[0009] A display control device, a display control method, and a program according to an embodiment of the present disclosure will be described below with reference to the drawings. The display control device manages, for example, plans for trading electricity generated by a plant. At this time, the display control device displays the plans for trading electricity in a manner that is understandable to the user, thereby enabling the user to consider and decide on the plans for trading electricity. The display control device according to this embodiment will be described below.

[0010] (Display control device) FIG. 1 is a schematic block diagram showing a system configuration of a power management device 10 (display control device) according to the present disclosure. The power management device 10 is communicatively connected to a plant P via a network 70. The network 70 may be a network using wireless communication or a network using wired communication. The network 70 may be configured using, for example, the Internet or a local area network (LAN). The network 70 may also be configured by combining a plurality of networks.

[0011] The power management device 10 performs processing related to an EMS (Energy Management System). An EMS is, for example, a system for managing the demand and supply of electric power in a specific plant P. By introducing an EMS, for example, the demand and supply of electric power can be optimized. As a result, it may be possible to reduce costs compared to not introducing an EMS. Introducing an EMS in a plant P means, for example, that the plant P is controlled by the EMS. Introducing an EMS in a plant P may also mean, for example, that the demand and supply of electric power in the plant P are controlled by the EMS.

[0012] Here, the plant P may be at least a part of a facility such as a water treatment facility, a production facility, a power generation facility, a storage facility, a waste disposal facility, etc. In this embodiment, the plant P is assumed to be a power generation facility that uses wind power, thermal power, hydropower, etc. If the plant P is a facility other than a power generation facility, the plant P may secondarily generate electricity by utilizing energy generated within the plant P when the plant P fulfills its primary purpose. For example, if the plant P includes a waste treatment facility, the plant P may secondarily generate electricity by utilizing thermal energy generated when the plant P treats (e.g., incinerates) waste.

[0013] The plant P may be a single plant (one facility) or a group of plants (multiple facilities) that can supply and demand power to each other. For example, if the plant P is a group of plants, the plant P may include, in addition to at least some of the facilities, a solar power generation facility, a storage battery, and an on-site cogeneration system. If the plant P is a group of plants, the distance between the multiple facilities is not limited, and the multiple facilities do not need to be located close to each other.

[0014] The power management device 10 may consider, for example, the cost reduction effect assuming the introduction of a storage battery. In this case, the power management device 10 may, for example, charge the storage battery with power during the day when the electricity price is low, and discharge the power stored in the storage battery during the night when the electricity price is high. The power discharged from the storage battery may be sold to the market or consumed in the plant P. The power management device 10 may, for example, consider the cost reduction effect on the premise of controlling the amount of power generated by the plant P. In this case, the power management device 10 may, for example, suppress the amount of power generated by the plant P during the day when electricity prices are low, and increase the amount of power generated by the plant P during the night when electricity prices are high. For example, if the plant P is a power generation facility, the power generation facility may not be operated during the day to set the amount of power generated to 0, and may be operated at the upper limit of its capacity at night to set the amount of power generated to 100% of its capacity. For example, the power management apparatus 10 may consider the cost reduction effect based on the adjustment of the demand (e.g., air conditioning, etc.). For example, the power management apparatus 10 may level the demand, change the demand in accordance with the electricity price, or change the demand in accordance with the supply.

[0015] The power management device 10 introduces an EMS into the plant P and functions as a control device that controls the plant P using the EMS. For example, the power management device 10, as the control device, formulates a plan for controlling the power supply and demand of the plant P. For example, the power management device 10, as the control device, controls the power supply and demand of the plant P in accordance with the formulated plan.

[0016] The user of the power management apparatus 10 may be, for example, an EMS business operator or a customer of the business operator. The customer may be, for example, a corporation that owns the plant P or a corporation that manages the plant P.

[0017] 2 is a schematic block diagram showing a specific example of the functional configuration of a power management apparatus 10 (display control device). The power management apparatus 10 is configured using information devices (information processing devices) such as smartphones, tablets, personal computers, dedicated devices, and server devices. The power management apparatus 10 includes a communication unit 11, an input unit 12, a display unit 13, a storage unit 14, and a control unit 15.

[0018] The communication unit 11 is a communication device. The communication unit 11 may be configured as, for example, a network interface. The communication unit 11 communicates data with other devices via a network in accordance with the control of the control unit 15. The communication unit 11 may be a device that performs wireless communication or a device that performs wired communication.

[0019] The input unit 12 is configured using existing input devices such as a keyboard, a pointing device (such as a mouse or tablet), buttons, or a touch panel. The input unit 12 is operated by a user when inputting user instructions to the power management apparatus 10. The input unit 12 may be an interface for connecting the input device to the power management apparatus 10. In this case, the input unit 12 inputs an input signal generated in the input device in response to a user input to the power management apparatus 10. The input unit 12 may be configured using a microphone and a voice recognition device. In this case, the input unit 12 acquires an acoustic signal generated by the user's speech, performs voice recognition on the words spoken by the user, and inputs character string information of the recognition result to the power management apparatus 10. The voice recognition process may be performed by the control unit 15. The input unit 12 may be configured in any way as long as it is capable of inputting user instructions to the power management apparatus 10.

[0020] Display unit 13 outputs information in a form that can be recognized by the user. Display unit 13 may be, for example, an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. Display unit 13 may be an interface for connecting an image display device to power management device 10. In this case, display unit 13 generates a video signal for displaying image data and outputs the video signal to an image display device connected to itself. Display unit 13 may be, for example, a printer. Display unit 13 may be an interface for connecting a printer to power management device 10. In this case, display unit 13 generates a print signal for printing print data and outputs the print signal to a printer connected to itself. Note that display unit 13 may be configured as a touch panel integrated with input unit 12. The various types of information displayed on the display unit 13 in this embodiment will be described in detail later.

[0021] The storage unit 14 is configured using a storage device such as a magnetic hard disk drive or a semiconductor storage device. The storage unit 14 stores data used by the control unit 15. The storage unit 14 stores data required when the control unit 15 performs processing. The storage unit 14 functions as a power supply information storage unit 141, an electricity price information storage unit 142, a CO2 emission price information storage unit 143, an electricity demand information storage unit 144, a plan information storage unit 145, and a performance information storage unit 146.

[0022] The power source information storage unit 141 stores power source information. The power source information is information related to a power source. The power source is, for example, a power generation facility. The power generation facility is, for example, a solar power generation facility, a waste disposal facility, a wind power generation facility, a storage battery, a cogeneration system, etc.

[0023] Here, the information that serves as the basis for calculating the power generation cost differs depending on the type of plant P. For example, if the power source is a waste treatment facility, the information that serves as the basis for the calculation may be information regarding the cost of a combustion aid. The combustion aid is required to incinerate (combust) the waste. For example, if the power source is a cogeneration system, the information that serves as the basis for the calculation may be information regarding the cost of fuel. Examples of such fuel include natural gas, oil, and LP gas. The fuel is used to generate power in the cogeneration system. If the power source is a storage battery, the information that serves as the basis for the calculation may be information regarding the depreciation cost of the storage battery (for example, storage battery cost / useful life, etc.).

[0024] The power price information storage unit 142 stores power price information. The power price information is information relating to power prices. The power price may be treated as not varying over time, or may be treated as varying over time. When the power price is treated as not varying over time, the power price is a fixed price. In this case, the power price information storage unit 142 may store a constant value (fixed price) as the power price information.

[0025] The CO2 emission price information storage unit 143 stores CO2 emission price information. The CO2 emission price information is information related to the CO2 emission price. The CO2 emission price is, for example, the cost required to emit a unit amount of CO2. The cost may include, for example, a fine imposed by the national or local government. The CO2 emission price may be a fixed price or a variable price. If the CO2 emission price is a variable price, the CO2 emission price information storage unit 143 may store a CO2 emission price information table. In this case, the CO2 emission price information table may have a structure similar to that of the electricity price information table.

[0026] The power demand information storage unit 144 stores power demand information. The power demand information is information related to the amount of power demanded in the plant P. The plant P consumes power, for example, for air conditioning devices in a warehouse owned by the plant P.

[0027] The plan information storage unit 145 stores plan information. The plan information is, for example, information about a plan created by the planning means 151 described below. The plan information is updated, for example, after the plan is created by the planning means 151. The plan information storage unit 145 may store information about a plan in the case where an EMS is not introduced (hereinafter also referred to as "plan information in the case where an EMS is not introduced") in addition to the plan information created by the planning means 151 (hereinafter also referred to as "plan information in the case where an EMS is not introduced"). The plan information in the case where an EMS is not introduced is, for example, plan information that is set in advance and not by the power management apparatus 10. The plan information in the case where an EMS is not introduced may be input, for example, from the input unit 12.

[0028] The performance information storage unit 146 stores performance information. The performance information is information relating to the performance of control performed by the control means 152, which will be described later. The performance information is updated, for example, after the control is performed by the control means 152.

[0029] The control unit 15 is configured using a processor such as a CPU (Central Processing Unit) and a memory (main storage device). The control unit 15 functions as planning means 151 and control means 152 when the processor executes a program. All or part of the functions of the control unit 15 may be realized using hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The program may be recorded on a computer-readable recording medium. Examples of computer-readable recording media include portable media such as flexible disks, magneto-optical disks, ROMs, CD-ROMs, and semiconductor storage devices (e.g., SSDs: Solid State Drives), as well as storage devices such as hard disks and semiconductor storage devices built into computer systems. The program may be transmitted via a telecommunications line.

[0030] The control unit 15 may execute, for example, an application installed in its own device (the power management apparatus 10). A specific example of such an application is an application provided to the power management apparatus 10 as a dedicated application for the power management system 100. Another specific example of such an application is a web browser application. Such an application may be pre-installed in the power management apparatus 10, or may be downloaded each time a determination process is executed. For example, when implemented as a web browser application, the power management apparatus 10 may download and execute the application from a device specified by a specific web server (for example, the web server itself or another server) in response to the power management apparatus 10 connecting to the web server. The control unit 15 operates according to the program of the application being executed.

[0031] The planning means 151, for example, makes a plan regarding the use of the power generated by the plant P. In this embodiment, the power generated by the plant P is, for example, <1> Trading electricity in the electricity market; <2> Negotiated transactions, <3> It is used to control the amount of power consumed by the facility, etc. Hereinafter, the power generated by the plant P may be simply referred to as the generated power.

[0032] <1> Electricity trading in the electricity market The generated electricity is used for trading in electricity markets, for example. Electricity trading takes place in, for example, <1-1> wholesale markets, <1-2> supply and demand balancing markets, and <1-3> capacity markets.

[0033] <1-1> Wholesale Market The buying and selling of electricity in a wholesale market is an example of trading of electricity in an electricity market. The buying and selling of electricity in a wholesale market is conducted, for example, between a plant P and the Japan Electric Power Exchange. The wholesale market includes, for example, a spot market and an hour-ahead market. The spot market is a market in which transactions are completed the day before the actual supply and demand of electricity. The hour-ahead market is a market where trading takes place up until just before the actual supply and demand of electricity (at least within the day, for example, one hour before). <1-2> Supply and demand adjustment market The buying and selling of electricity in a supply and demand balancing market is an example of electricity trading in an electricity market. A supply and demand balancing market is a market for securing adjustment power to adjust the balance between supply and demand in the electricity market. Transactions in the supply and demand balancing market include, for example, primary adjustment power, secondary adjustment power (1), secondary adjustment power (2), tertiary adjustment power (1), and tertiary adjustment power (2). Primary adjustment power is, for example, adjustment power for suppressing an increase or decrease in the frequency of electricity. Secondary adjustment power (1) and secondary adjustment power (2) are, for example, adjustment power for restoring the frequency of electricity to a reference frequency. Tertiary adjustment power (1) and tertiary adjustment power (2) are, for example, adjustment power for economically adjusting the supply and demand of electricity.

[0034] <1-3>Capacity market The buying and selling of electricity in a capacity market is an example of electricity trading in an electricity market. The capacity market is a market for securing an amount of electricity that can be used to respond to electricity supply shortages in order to stabilize the supply and demand relationship of electricity. Trading in a capacity market is carried out, for example, when plant P is a thermal power plant where it is easy to adjust the amount of power generated. EMS operators or their customers predetermine through contracts the amount of electricity they will supply when they receive a request to supply electricity to the capacity market. Such requests are made, for example, by general electricity transmission and distribution companies to EMS operators or their customers. The supply amount under the contract is determined, for example, on a yearly basis. When an EMS receives a request to actually supply power to the capacity market, the EMS provides the market with at least the supply amount determined by the contract. The request is made, for example, on the day the power trading takes place. Therefore, the planning unit 151 does not need to take into account requests to supply power to the capacity market.

[0035] <2> Negotiated transactions The generated electricity may be used, for example, in bilateral trading. Bilateral trading of electricity may be conducted, for example, between the plant P and a retail electricity supplier. In this embodiment, the bilateral trading may be, for example, bilateral trading of renewable energy electricity. The generated power may be used, for example, to avoid imbalances in power trading. An imbalance refers to a difference between a power generation plan and actual power generation, or between a power demand plan and actual demand. Imbalance avoidance refers to avoiding imbalances. In this embodiment, imbalance avoidance may include imbalance avoidance corresponding to a single facility and imbalance avoidance corresponding to multiple facilities.

[0036] <3> Control of self-power consumption The generated power may be used, for example, to control the self-consumption power. The control of the self-consumption power may include, for example, self-consumption, self-transportation, demand response, peak cutting, and peak shifting. In such cases, the generated power may be temporarily charged in a storage battery provided in the plant P, for example, and transmitted from the storage battery as needed.

[0037] The planning means 151 adjusts the amount of power generated by the plant P and the amount of power stored in the storage battery of the EMS, and then considers which of the above-mentioned uses the generated power should be used for, thereby formulating a plan that will result in higher profits. For example, the planning means 151 first calculates the predicted amount of revenue based on the predicted value of the electricity price for the use of electricity, the predicted value of the amount of power generated by the solar power facilities and the like included in the plant P, and the predicted value of the amount of power demand in the plant P and the like. The calculation of the above-mentioned predicted amount may be performed for each time period for each of the multiple uses of electricity. For example, if there is equipment that can adjust the amount of power, such as a thermal power plant or a storage battery, the predicted amount of revenue may be calculated by taking into account the power generation costs and the like of these equipment for each time period and creating an operation plan for these equipment so that the predicted amount of revenue is larger. Next, the planning means 151 lists several combinations with large calculated predicted profit amounts, and then, taking into consideration the accuracy of the predictions for each use, the planning means 151 proposes several examples of combinations that are likely to generate profits more reliably.

[0038] The control means 152 controls the plant P based on the planning information from the planning means 151. The control means 152 may read out the planning information from, for example, the planning information storage unit 145. After controlling the plant P, for example, the control means 152 updates the performance information stored in the performance information storage unit 146 based on the performance of controlling the plant P.

[0039] (Information displayed on the display) The information displayed on the display unit 13 in this embodiment will be described. FIG. 3 is a schematic diagram of a screen displayed on the display unit 13. As shown in FIG. The power management device 10 (control unit 15 (display control device)) displays various information related to the management of power demand and supply by the EMS on the display unit 13. While checking the information displayed on the display unit 13, the user considers and decides, for example, how to use the generated power.

[0040] Specifically, the user uses the power management apparatus 10 to check the plan for controlling the power supply and demand of the plant P, which has been prepared by the planning means 151 of the power management apparatus 10. Then, the user creates a plan that appropriately reflects the user's intentions based on the plan prepared by the power management apparatus 10. The power management apparatus 10 trades power in accordance with the plan prepared as described above. The power management apparatus 10 displays, for example, on the display unit 13 an interface that allows the user to perform such operations.

[0041] As shown in Fig. 3, the power management apparatus 10 displays a profit calculation table I1, a fluctuation forecast graph I2, an individual use image I3, and a suppression mode intensity image I4 on the display unit 13. As shown in Fig. 3, on the display unit 13, for example, each of these pieces of information is arranged without overlapping on the same screen. This allows the user to grasp each piece of information by visually checking the display unit 13. In the example shown in Fig. 3, the profit calculation table I1 and the fluctuation forecast graph I2 are arranged side by side in the left-right direction of the display unit 13. The individual use image I3 and the suppression mode intensity image I4 are arranged side by side in the left-right direction of the display unit 13 below the profit calculation table I1 and the fluctuation forecast graph I2. However, the positional relationship between the profit calculation table I1, the fluctuation forecast graph I2, the individual use image I3, and the suppression mode intensity image I4 is not limited to this.

[0042] Revenue calculation table I1 is a table that displays the use of generated electricity for each 24-hour period in association with the revenue corresponding to that use. In this revenue calculation table I1, the first line is a heading, and the second line and subsequent lines are records corresponding to the heading. In the example shown, there are four records, and the table has five rows in total. Alternatively, the number of records may be five or more, or three or less. The table may have six or more rows, or three or less rows in total. Each record is, for example, a plan determined in advance by the power management apparatus 10 or a user. In each plan, one or more uses are determined for each time period. In each plan, for example, revenue for each plan is required. In each record, multiple images are displayed as information corresponding to each header row. As shown in FIG. 3, in the income calculation table I1, for example, a selection operation image SB, a usage image I1a, a suppression mode setting image I1b, an income image I1c, and an achievement image I1d are displayed. Each of these images displayed in the income calculation table I1 is included in each record. In the example shown in FIG. 3, the income calculation table I1 has five columns, and one of these images is displayed in each column.

[0043] The image for selection operation SB is an image that allows the user to select one of the multiple records displayed in the income calculation table I1. The image for selection operation SB is, for example, a so-called toggle button. One image for selection operation SB is provided for each of the multiple records displayed from the second row onwards in the income calculation table I1. The user selects one of the images for selection operation SB, for example, via the input unit 12. This operation is performed, for example, in the first selection step S2 described below. In the example shown in FIG. 3, the topmost of the multiple images for selection operation SB is displayed in black, and the others are displayed in white. This means that the record located at the top of the table is selected by the image for selection operation SB. In the example shown in FIG. 3, this means that the first use (described later) in the income calculation table I1 is selected.

[0044] The usage image I1a is an image showing the usage of generated power every 24 hours. Here, the usage of power is, for example, the above-mentioned <1> Trading electricity in the electricity market; <2> Negotiated transactions, <3> The purpose of the present invention may be to control the power consumption of the home, or may be to combine two or more of these purposes. In the usage image I1a, for example, the usage of electricity is represented by the market in which the electricity is traded. For example, if "wholesale market" is displayed in the usage image I1a (for example, the third record from the top in the illustrated example), it means that the generated electricity will be used only for trading in the wholesale market during 24 hours. For example, when "multiple market combination" is displayed in the usage image I1a, it means that the generated electricity is used for multiple purposes within a 24-hour period. Using the generated electricity for multiple purposes means, for example, that the usage of the generated electricity changes depending on the time of day within a 24-hour period. Alternatively, using the generated electricity for multiple purposes may mean using the generated electricity for multiple purposes within the same time period.

[0045] In this embodiment, the income calculation table I1 displays four records as described above. In other words, the income calculation table I1 displays first to fourth uses. In the example shown in Fig. 3, the use image I1a includes a first use image I1a1, a second use image I1a2, a third use image I1a3, and a fourth use image I1a4.

[0046] In this embodiment, for example, the second use image I1a2 (and the second revenue image I1c2 described later) is displayed below the first use image I1a1 (and the first revenue image I1c1 described later). More specifically, in the revenue calculation table I1, the first use image I1a1 to the fourth use image I1a4 are displayed in order from top to bottom. The first use image I1a1 to the fourth use image I1a4 correspond to each record, respectively.

[0047] The first use image I1a1 is an image showing a first use of power by the EMS. In the example shown in Fig. 3, the first use is a combination of multiple markets. The second use image I1a2 is an image showing the second use of electricity by the EMS. In the example shown in FIG. 3, the second use is a multiple market combination. In the illustrated example, the first use and the second use match. A match between the first use and the second use means that both the first use and the second use are a multiple market combination, and includes cases where the breakdown of the multiple uses is different. In other words, even if the first use and the second use match in a multiple market combination, the specific combination of the first use and the second use does not have to match. The third use image I1a3 is an image showing a third use of the electricity generated by the EMS. In the example shown in Fig. 3, the third use is a wholesale market. The wholesale market use means that the generated electricity is used only for trading in the wholesale market during a 24-hour period. The fourth use image I1a4 is an image showing a fourth use of electricity by the EMS. In the example shown in Fig. 3, the fourth use is the balancing market. The balancing market use means that the generated electricity is used only for trading in the balancing market during a 24-hour period.

[0048] In this embodiment, the first to fourth uses are uses on the same day. More specifically, in this embodiment, the first to fourth uses are uses of electricity on the following day. That is, the first to fourth uses are all uses on the day following the implementation date of the display control method according to this embodiment. By implementing the display control method according to this embodiment, the user makes an EMS operation plan for the day following the implementation date of the display control method according to this embodiment (details will be described later).

[0049] In this embodiment, one of the first purpose image I1a1 and the second purpose image I1a2 may correspond to, for example, a plurality of purposes of power provided by the EMS. The same applies to the third purpose image I1a3 and the fourth purpose image I1a4. That is, the first to fourth purposes may include a plurality of the above-mentioned purposes of power. In this embodiment, the multiple uses included in the first to fourth uses are, for example, one use that is expected to be highly profitable, or a combination of multiple uses that are expected to be even more profitable, selected appropriately by the planning means 151 from uses that the user has specified in advance. The use is specified by the user by, for example, inputting appropriate information into the power management device 10 via the input unit 12 in advance before the display control method according to this embodiment is performed.

[0050] The power management apparatus 10 may display on the display unit 13 in a manner that enables it to be distinguished that the first to fourth uses indicate multiple uses. That is, for example, the power management apparatus 10 may display a "multiple market combination" in the first use image I1a1 or the second use image I1a2 as shown in FIG. 3. Each of the multiple uses included in the multiple market combination may be selected, for example, by the planning means 151, or may be selected by the user inputting appropriate information via the input unit 12. Furthermore, the power management apparatus 10 may display the characters displayed in the first use image I1a1 or the second use image I1a2 in a color different from the other characters, or may display them in bold.

[0051] The degradation prevention mode setting image I1b indicates that the degradation prevention mode of the storage battery is ON or OFF for each of the first to fourth uses. The degradation prevention mode of the storage battery will be described later.

[0052] The revenue image I1c is an image showing the predicted revenue corresponding to the usage image I1a. In the example shown in Figure 3, the revenue image I1c includes a first revenue image I1c1, a second revenue image I1c2, a third revenue image I1c3, a fourth revenue image I1c4, and a detailed revenue image I1c5. The first revenue image I1c1 is an image showing a predicted value of the first revenue corresponding to the first use shown in the first use image I1a1. In the example shown in Figure 3, the first revenue is 29,000 yen. The second revenue image I1c2 is an image showing a predicted value of the second revenue corresponding to the second use shown in the second use image I1a2. In the example shown in Figure 3, the second revenue is 28,000 yen. The third revenue image I1c3 is an image showing a predicted value of the third revenue corresponding to the third use shown in the third use image I1a3. In the example shown in Fig. 3, the third revenue is 20,000 yen. The fourth revenue image I1c4 is an image showing a predicted value of a fourth revenue corresponding to the fourth use shown in the fourth use image I1a4. In the example shown in FIG. 3, the fourth revenue is 10,000 yen.

[0053] In the present embodiment, the power management apparatus 10 causes the display unit 13 to display the first usage image I1a1 and the first revenue image I1c1 in association with each other, and also causes the display unit 13 to display the second usage image I1a2 and the second revenue image I1c2 in association with each other. This allows the user to compare the first usage image I1a1 and the first revenue image I1c1 with the second usage image I1a2 and the second revenue image I1c2. In addition to the above, the power management device 10 may cause the display unit 13 to display the third use image I1a3 and the third revenue image I1c3, and the fourth use image I1a4 and the fourth revenue image I1c4 in correspondence with each other. The first purpose-use image I1a1 to the fourth purpose-use image I1a4 correspond to each record.

[0054] The detailed revenue image I1c5 is an image showing details of the revenue. For example, the detailed revenue image I1c5 is an image showing one of the predicted revenue and the actual revenue included in each of the first to fourth revenues shown in the first to fourth revenue images I1c1 to I1c4, and the cost of the storage battery. The following description will be given taking the detailed revenue image I1c5 related to the first revenue image I1c1 as an example, but the same applies to the second to fourth revenue images I1c2 to I1c4. Which of the first to fourth revenue images I1c1 to I1c4 is related to in the detailed revenue image I1c5 depends on which of the first to fourth uses is selected by the selection operation image SB. The detailed revenue image I1c5 shows which of the first to fourth revenue images I1c1 to I1c4 displayed in the revenue calculation table I1 is related to the use selected by the selection operation image SB. The detailed revenue image I1c5 is, for example, an image showing either the predicted revenue or the actual revenue included in the first revenue indicated by the first revenue image I1c1, and the cost of the storage battery. That is, in this embodiment, the first revenue includes the predicted revenue or the actual revenue. For example, when a user selects the selection operation image SB corresponding to the first use image I1a1 displayed on the display unit 13 using the input unit 12, the detailed revenue image I1c5 corresponding to the first revenue is displayed in a speech bubble, as shown in FIG. 3.

[0055] In the example shown in FIG. 3, the detailed revenue image I1c5 shows, for example, a breakdown of the predicted revenue from the electricity trading portion and the revenue resulting from the extended life of the storage battery (the cost of the storage battery). The revenue from the power trading is the revenue from buying and selling the power generated by the plant P. The revenue (cost of the storage battery) resulting from the extended life of the storage battery is, for example, the benefit of suppressing the deterioration of the storage battery by operating the storage battery in a degradation suppression mode that suppresses its deterioration, thereby delaying the replacement of the storage battery. In other words, the first revenue includes the cost of the storage battery that can be reduced by operating the storage battery in a degradation suppression mode with a first intensity, which will be described later.

[0056] Alternatively, the detailed revenue image I1c5 may display the cost of the battery incurred by not operating the battery in the degradation control mode, instead of the revenue for the extended battery life due to operating the battery in the degradation control mode. In other words, the first revenue may include the cost of the battery incurred by not operating the battery in the degradation control mode with the first intensity, which will be described later. By visually checking the detailed revenue image I1c5 displayed in this way, the user can understand the expected revenue or actual revenue and the cost of the storage battery.

[0057] The performance image I1d is an image showing the performance of revenue when the generated electricity is used for the purpose corresponding to the purpose image I1a. The performance information displayed in the performance image I1d is output based on past information as of the date related to the information shown in the revenue calculation table I1, for example. The performance image I1d includes an accuracy image I1d1 and an average revenue image I1d2. The accuracy image I1d1 displays the accuracy of the predicted revenue shown in the revenue image I1c based on the ratio of the predicted revenue shown in the average revenue image I1d2 to the actual revenue for the same date in the past. In the example shown in Figure 3, the accuracy of the predicted revenue shown in the first revenue image I1c1 is -6 to +7%. The average revenue image I1d2 displays the average revenue for the same day in the past for the date associated with the average revenue image I1d2. In the example shown in Figure 3, for example, the average revenue for the same day in the past for the date associated with the first revenue image I1c1 is 30,000 yen. Four precision images I1d1 and four average profit images I1d2 are provided corresponding to the first purpose-use images I1a1 to the fourth purpose-use images I1a4.

[0058] The fluctuation forecast graph I2 is a graph showing predicted fluctuations in the price of electricity for each market by time period and predicted fluctuations in the amount of power generated by each time period. In this embodiment, the fluctuation forecast graph I2 displays, for example, the revenue calculation table I1 that corresponds to the use selected by the selection operation image SB. In the example shown in FIG. 3, the fluctuation forecast graph I2 that corresponds to the first use image I1a1 is displayed. 4 is an enlarged view of the fluctuation prediction graph I2 displayed on the display unit 13. The fluctuation prediction graph I2 shown in FIG. 4 is displayed on the display unit 13 at the position of the fluctuation prediction graph I2 shown in FIG. As shown in FIG. 4, a fluctuation prediction graph I2 displays a fluctuation image I2a, a time period image I2b, and a detailed use image I2c.

[0059] The fluctuation image I2a is a line graph showing fluctuations in the price or power generation amount for each electricity market. The fluctuation image I2a shows fluctuations in the price or power generation amount for each 30-minute period, for example. By visually checking the fluctuation image I2a, the user can understand fluctuations in the price of electricity for each time period. The fluctuation image I2a includes a price graph I2a1 and an electricity generation amount graph I2a2. Price graph I2a1 shows fluctuations in electricity prices by time period for each market. Price graph I2a1 shows, for example, forecasts of price fluctuations every 24 hours. The vertical axis of price graph I2a1 is the trading price of electricity. The unit of electricity trading price is, for example, yen / kWh in wholesale markets and imbalance markets, and yen / kW in supply and demand adjustment markets. The power generation amount graph I2a2 shows fluctuations in the amount of power generated for each time period. The power generation amount graph I2a2 shows, for example, a forecast of the amount of power generated for each 24-hour period. The vertical axis of the power generation amount graph I2a2 is the unit of the amount of power generated (for example, kWh).

[0060] The time zone images I2b respectively represent multiple time zones in the fluctuation prediction graph I2. Multiple time zone images I2b are provided along the horizontal axis of the fluctuation prediction graph I2. In other words, the horizontal axis of the fluctuation prediction graph I2 is time. In this embodiment, the use of generated electricity is determined every 30 minutes. The fluctuation forecast graph I2 shows the predicted price value for every 24 hours. Therefore, in the fluctuation forecast graph I2, 48 time zone images I2b are provided, each representing a 30-minute interval. Alternatively, the time zone image I2b may represent any time other than 30 minutes. For example, the time zone image I2b may represent one hour, 15 minutes, or any other time zone.

[0061] The detailed use image I2c is an image that shows the use of the generated electricity in the fluctuation forecast graph I2. In this embodiment, the detailed use image I2c displays, for example, an image from the profit calculation table I1 that corresponds to the use selected in the selection operation image SB. In the example shown in FIGS. 3 and 4, the detailed use image I2c displayed corresponds to the first use image I1a1. For example, the example shown in Figure 3 indicates that the generated electricity will be used for trading in the wholesale market during the time period from 0:00 to 4:00. The generated electricity will be used for trading in multiple markets (multiple market combination) during the time period from 4:00 to 12:00. The generated electricity will be used to avoid imbalances during the time period from 12:00 to 18:00. The generated electricity will be used again for trading in the wholesale market during the time period from 18:00 to 0:00 the following day. The user can visually check the detailed use image I2c to understand the use of the generated power for each time period. The user may also determine the use of the generated power for each time period by operating the detailed use image I2c via the input unit 12 (details will be described later).

[0062] The individual use image I3 is a pie chart showing the proportion of uses of generated electricity for each time period. In this embodiment, the individual use image I3 shows the proportion of uses of generated electricity for each time period indicated by the time period image I2b. In the example shown in FIG. 3, the individual use image I3 shows the proportion of uses of generated electricity for each 30-minute period. In this embodiment, such a pie chart, which corresponds to one day, is made up of 48 time frames, each 30 minutes long. If the time period image I2b shows any time other than 30 minutes, the time shown by the individual use image I3 may also correspond to the time shown by the time period image I2b.

[0063] In this embodiment, the display unit 13 displays an individual use image I3 corresponding to one of the 48 time frames. In the example shown in FIG. 3, the individual use image I3 displayed corresponds to the time slot from 0:00 to 0:30. The example shown in FIG. 3 indicates that all of the electricity generated during the time slot from 0:00 to 0:30 is used for trading in the wholesale market. Note that which of the individual use images I3 composed of the 48 time frames corresponds to which time slot is displayed on the display unit 13 is determined, for example, by the user selecting one of multiple time slot images I2b via the input unit 12. This operation is performed, for example, in a first selection step S2 described later.

[0064] FIG. 5 is a first example of an individual use image I3 corresponding to a combination of multiple markets. FIG. 6 is a second example of an individual use image I3 corresponding to a combination of multiple markets. Here, the generated electricity may be used for multiple purposes during the same time period. In such cases, the individual use image I3 may show each of the multiple purposes. That is, as shown in Fig. 5, the individual use image I3, which is a pie chart, may display the multiple purposes by percentage, so that the percentage of the purpose to which the electricity is used can be visually seen. The example shown in Fig. 5 shows that, for example, during the time period from exactly 4:00 PM to 4:30 PM, one-third of the generated electricity is used for trading in the wholesale market, one-third is used in the balancing market, and the remaining one-third is used for imbalance prevention and other purposes. Furthermore, as shown in FIG. 6, for example, the individual use image I3 may be a stacked bar graph. In this case, the vertical axis of the individual use image I3 may be, for example, the amount of electricity in each market, the profit in each market, or the profit fluctuation risk in each market including the variation in past accuracy. In the individual use image I3, the vertical axis may be displayed so that any of the above can be switched. The horizontal axis of the individual use image I3 may be time. Specifically, a plurality of time period images I2b may be displayed side by side on the horizontal axis of the individual use image I3.

[0065] Returning to FIG. 3, the suppression mode intensity image I4 is an image showing the intensity of the deterioration suppression mode by the EMS of the storage battery. Here, the battery degradation suppression mode is a mode that suppresses the degradation of the storage battery by suppressing its output. For example, if profits are to be increased by trading more electricity during a time period when the price of electricity is relatively high, it is preferable to increase the output of the storage battery by lowering the intensity of the degradation suppression mode or turning it off. If the amount of electricity traded is reduced or electricity is consumed for personal consumption during a time period when the price of electricity is relatively low, the intensity of the degradation suppression mode may be increased to suppress the output of the storage battery.

[0066] As shown in Figure 3, the suppression mode intensity image I4 includes a time-zone-specific intensity image I4a, a time-zone-specific usage image I4b, a first intensity image I4c, a second intensity image I4d, a third intensity image I4e, a fourth intensity image I4f, and an intensity adjustment operation image I4g. The time-zone intensity image I4a (time zone image) is an image that indicates the time zones in the suppression mode intensity image I4. In the example shown in Fig. 3, the time-zone intensity image I4a displayed corresponds to the first purpose image I1a1 selected with the selection operation image SB. That is, in the example shown in Fig. 3, the time-zone intensity image I4a indicates the time zones from 0:00 to 4:00, from 4:00 to 12:00, from 12:00 to 18:00, and from 18:00 to 0:00 the next day.

[0067] The time-zone usage image I4b is an image showing the usage of power corresponding to each of the time periods shown in the time-zone intensity image I4a. The time-zone usage image I4b appropriately displays the usage of power in the corresponding time period corresponding to each of the times displayed in the time-zone intensity image I4a.

[0068] The first intensity image I4c is an image indicating the intensity of the degradation suppression mode corresponding to the first purpose image I1a1. In the present embodiment, the first intensity image I4c is displayed on the display unit 13 in association with each of the multiple time-slot intensity images I4a indicating multiple time slots, respectively. In the example shown in Fig. 3, the first intensity image I4c indicates that the intensity of the degradation suppression mode changes from Level 7 to Level 2, Level 7, and Level 7 as time progresses.

[0069] In this embodiment, the strength of the degradation suppression mode is, for example, stronger as the Lv. value is larger, and weaker as the value is smaller. Alternatively, the intensity of the degradation suppression mode may be indicated as a percentage from 0 to 100% instead of a numerical value of Level. In this case, the intensity of the degradation suppression mode may be indicated, for example, as the percentage value is smaller, the intensity is stronger, and as the value is larger, the intensity is weaker.

[0070] The second intensity image I4d, the third intensity image I4e, and the fourth intensity image I4f are all similar to the first intensity image I4c, but differ in the following respects: The second intensity image I4d indicates the intensity of the degradation control mode corresponding to the second-purpose image I1a2; The third intensity image I4e indicates the intensity of the degradation control mode corresponding to the third-purpose image I1a3; and The fourth intensity image I4f indicates the intensity of the degradation control mode corresponding to the fourth-purpose image I1a4. Which of the first intensity image I4c to the fourth intensity image I4f is displayed on the display unit 13 is determined by which of the first to fourth uses the user selects. For example, in the example shown in FIG. 3, the first use is selected by the selection operation image SB as described above. Therefore, in the example shown in FIG. 3, the first intensity image I4c corresponding to the first use image I1a1 is displayed. For example, when the second use is selected by the selection operation image SB, the second intensity image I4d corresponding to the second use image is displayed on the display unit 13. The same applies to the third intensity image I4e and the fourth intensity image I4f.

[0071] The intensity adjustment operation image I4g is used to operate the numerical value of the intensity level of the degradation suppression mode. The numerical value of the intensity level of the degradation suppression mode is operated, for example, by the user appropriately selecting, via the input unit 12, one of the first intensity images I4c displayed corresponding to each of the time periods indicated by the time period intensity image I4a. When operating the intensity of the degradation suppression mode using the intensity adjustment operation image I4g, the user selects one of the first intensity image I4c to fourth intensity image I4f displayed in the suppression mode intensity image I4. When the user operates the intensity adjustment operation image I4g, the numerical value of the intensity level of the degradation suppression mode of the selected one of the first intensity image I4c to fourth intensity image I4f changes. The user may increase the level of the intensity of the degradation suppression mode by, for example, selecting the upper triangular button of the intensity adjustment operation image I4g using the input unit 12. The user may decrease the level of the intensity of the degradation suppression mode by selecting the lower triangular button of the intensity adjustment operation image I4g. In the power management device 10 according to this embodiment, the above information is displayed on the display unit 13.

[0072] 7 is a diagram illustrating an outline of an example of the hardware configuration of an information processing device 90 applied to this embodiment. The information processing device 90 includes a processor 91, a main memory device 92, a communication interface 93, an auxiliary memory device 94, an input / output interface 95, and an internal bus 96. The processor 91, the main memory device 92, the communication interface 93, the auxiliary memory device 94, and the input / output interface 95 are communicably connected to each other via the internal bus 96. The information processing device 90 may be applied to, for example, a power management device 10. In this case, for example, the communication unit 11 may be configured using the communication interface 93. For example, the memory unit 14 may be configured using the auxiliary memory device 94. Furthermore, the control unit 15 may be configured using the processor 91 and the main memory device 92.

[0073] The operations of the control unit 15 described above are stored in the form of a program in an auxiliary storage device 94 (storage). The processor 91 reads the program from the auxiliary storage device 94, loads it into the main storage device 92, and executes the above-mentioned processing in accordance with the program. The processor 91 also allocates storage areas in the main storage device 92 corresponding to the above-mentioned storage units 14 in accordance with the program. Examples of the processor 91 include a CPU (Central Processing Unit), a GPU (Graphic Processing Unit), and a microprocessor.

[0074] The program may be for realizing some of the functions to be performed by the information processing device 90. For example, the program may be combined with other programs already stored in the auxiliary storage device 94 or other programs implemented in other devices to perform the functions. In another example of the embodiment, the information processing device 90 may include a custom LSI (Large Scale Integrated Circuit) such as a PLD (Programmable Logic Device) in addition to or instead of the above configuration. Examples of PLDs include PAL (Programmable Array Logic), GAL (Generic Array Logic), CPLD (Complex Programmable Logic Device), and FPGA (Field Programmable Gate Array). In this case, some or all of the functions realized by the processor 91 may be realized by the integrated circuit. Such an integrated circuit is also included as an example of a processor.

[0075] Examples of the auxiliary storage device 94 include a magnetic disk, a magneto-optical disk, an optical disk, and a semiconductor memory. The auxiliary storage device 94 may be an internal medium directly connected to the bus of the information processing device 90, or an external medium connected to the information processing device 90 via the input / output interface 95 or a communication line. Furthermore, when this program is distributed to the information processing device 90 via a communication line, the information processing device 90 that has received the program may load the program into the main storage device 92 and execute the above-mentioned processing. In at least one embodiment, the auxiliary storage device 94 is a non-transitory tangible storage medium.

[0076] The program may also be for realizing part of the above-mentioned functions. Furthermore, the program may be a so-called differential file (differential program) that realizes the above-mentioned functions in combination with another program already stored in the auxiliary storage device 94.

[0077] The power management apparatus 10 may be implemented using a plurality of information processing devices. For example, the power management apparatus 10 may be implemented using a device such as a cloud. For example, in the power management apparatus 10, the storage unit 14 and the control unit 15 may be implemented in different information processing devices. For example, the storage unit 14 of the power management apparatus 10 may be distributed and implemented in a plurality of information processing devices.

[0078] (Display control method) Next, a display control method according to this embodiment will be described, that is, the processing content of the power management apparatus 10 for displaying various types of information on the display unit 13 will be described. FIG. 8 is a flowchart of the display control method of this embodiment. 8, the display control method according to this embodiment includes a first display control step S1, a first selection step S2, a repetition count determination step S2.5, a determination step S3, a second display control step S4, a designation step S5, and a second selection step S6. These steps are repeatedly performed unless the user issues an instruction to end the display control method (S0: NO). In the following description, only the first and second uses will be described as examples, but the display control method according to this embodiment may also be implemented for uses including the third and fourth uses.

[0079] The first display control step S1 is a step of associating the first use image I1a1 and the first revenue image I1c1 and displaying them on the display unit 13, and also of associating the second use image I1a2 and the second revenue image I1c2 and displaying them on the display unit 13.

[0080] In this embodiment, the uses related to the first use image I1a1 and the second use image I1a2 displayed as described above may be in accordance with a plan drawn up by the planning means 151, for example. The first use may also be included in the uses of power selected by the user. Here, the user may visually check the fluctuation image I2a of the fluctuation forecast graph I2 to consider and decide which uses should be included in the first use or which uses should not be included in the first use. In such a case, the user inputs the uses to be included in the first use via the input unit 12. The planning means 151 may determine the first use based on the information thus input by the user.

[0081] In this embodiment, one of the first use image I1a1 and the second use image I1a2 corresponds to a plurality of uses of power provided by the EMS. That is, either the first use related to the first use image I1a1 or the second use related to the second use image I1a2 may be a use for a combination of multiple markets. Note that the plurality of uses are, for example, high-profit uses or high-profit combinations appropriately selected by the planning unit 151 from uses previously designated by the user. At this time, in the first display control step S1, the power management device 10 may display on the display unit 13 in a manner that makes it possible to distinguish that one of the first usage image I1a1 and the second usage image I1a2 indicates multiple usages. Specifically, for example, the power management device 10 may display "multiple market combinations" in the first usage image I1a1 or the second usage image I1a2 as shown in Fig. 3. Furthermore, the power management device 10 may display the characters displayed in the first usage image I1a1 or the second usage image I1a2 in a color different from the other characters, or may display them in bold.

[0082] In the first display control step S1, the power management apparatus 10 may display at least one of the first-purpose image I1a1 and the second-purpose image I1a2 on the display unit 13 so that the image can be selected in the first selection step S2. In addition, in the first display control step S1, the power management device 10 may cause the display unit 13 to display the first use image I1a1 and the first revenue image I1c1, and the second use image I1a2 and the second revenue image I1c2 so that they can be compared.

[0083] The first selection step S2 is a step in which the user selects one of the first-purpose image I1a1 and the second-purpose image I1a2, which indicates multiple purposes. In the first selection step S2, the user may select one of the first-purpose image I1a1 and the second-purpose image I1a2, which indicates only one purpose. The selection in the first selection step S2 is made by the user appropriately selecting either one of the selection operation images SB corresponding to the first use or the second use via the input unit 12. Hereinafter, for example, the selection of the first use in the first selection step S2 may be referred to as the selection of the first use image I1a1.

[0084] After first selection step S2, power management device 10 determines the number of repetitions of first selection step S2 in repetition count determination step S2.5. If the repetition count is less than 1, i.e., 0 (S2.5: NO), power management device 10 returns to first display control step S1 and performs the following additional processing in first display control step S1. On the other hand, if the repetition count is 1 or more (S2.5: YES), power management device 10 performs determination step S3.

[0085] As described above, if the number of repetitions of the first selection step S2 is 0 (S2.5: NO), the process returns to the first display control step S1, and a plurality of individual use images I3 indicating each of the plurality of uses indicated by one of the first use image I1a1 and the second use image I1a2 are displayed on the display unit 13 in a size corresponding to the amount of power corresponding to each of the plurality of individual use images I3. At this time, the user may manipulate the proportion of the uses of the generated power, for example, by changing the proportion of the plurality of uses included in the individual use image I3 shown in FIG. 5 via the input unit 12.

[0086] In this first display control step S1, the power management device 10 may associate the suppression mode intensity image I4 with the profit calculation table I1 and display it on the display unit 13. For example, when the user selects the first use image I1a1 displayed on the profit calculation table I1, the power management device 10 may display the time-of-day intensity image I4a corresponding to the first use on the display unit 13. Furthermore, in this first display control step S1, the power management device 10 may display the first intensity image I4c on the display unit 13 in association with the first use image I1a1 and the first revenue image I1c1, and may display the second intensity image I4d on the display unit 13 in association with the second use image I1a2 and the second revenue image I1c2. This may allow the user to easily change the intensity of the deterioration suppression mode of the storage battery when considering the details of the first use or the second use.

[0087] Furthermore, in this first display control step S1, the power management device 10 may display, on the display unit 13, a plurality of detailed use images I2c indicating each of the multiple uses indicated by one of the first use image I1a1 and the second use image I1a2, in association with a plurality of time period images I2b indicating each of the multiple time periods. This may make it easier for the user to perform the designation step S5.

[0088] As described above, if the number of repetitions of the first selection step S2 is one or more (S2.5: YES), the power management apparatus 10 performs the determination step S3. The determination step S3 is a step for determining whether or not one of the first-purpose image I1a1 and the second-purpose image I1a2 is selected in the first selection step S2. In this embodiment, the determination step S3 further determines whether or not the user has selected a different purpose from the purpose selected in the previous first selection step S2. If a purpose different from the purpose selected in the previous first selection step S2 is selected (S3: YES), the power management apparatus 10 performs the first display control step S1 again in accordance with the selected purpose. If the purpose selected in the previous first selection step S2 has not changed (S3: NO), the power management apparatus 10 proceeds to the second display control step S4.

[0089] The second display control step S4 is a step of displaying, on the display unit 13, detailed use images I2c indicating each of the multiple uses indicated by the selected one of the first use image I1a1 and the second use image I1a2 when the determination step S3 determines that one of the first use image I1a1 and the second use image I1a2 has been selected and when there is no change in the selected use (S3: NO). For example, when the user selects the first use image I1a1, the power management apparatus 10 makes it possible to refer to the multiple uses included in the first use by time period in the fluctuation prediction graph I2, as shown in FIGS. 3 and 4. In the second display control step S4, detailed use images I2c corresponding to the selected first use or second use are displayed on each of the multiple time period images I2b displayed on the fluctuation prediction graph I2.

[0090] The designation step S5 is a step of designating one of the time periods indicated by the time period images I2b to correspond to one of the detailed use images I2c. Specifically, for example, the user selects one of the multiple time zone images I2b displayed on the fluctuation forecast graph I2, and also specifies one of the multiple detailed use images I2c, and associates one of the selected time zone images I2b with one of the specified detailed use images I2c. As a result, as shown in FIGS. 3 and 4, the plurality of time zone images I2b and the plurality of detailed use images I2c are displayed on the display unit 13 in association with each other. The designation step S5 may be performed, for example, for the time period displayed on the display unit 13, up to one hour before the actual start of the electricity transaction.

[0091] In electricity trading, the primary control reserve, secondary control reserve, tertiary control reserve (1), and capacity market transactions may be awarded before the day before the implementation date of the display control method. In this case, the content of these transactions cannot be changed on the implementation date of the display control method or the day after. In this embodiment, in such a case, one of the multiple detailed use images I2c displayed on the display unit 13 may not include the primary control reserve, secondary control reserve, tertiary control reserve (1), and capacity market transactions. In other words, the power management apparatus 10 may not include the primary control reserve, secondary control reserve, tertiary control reserve (1), and capacity market transactions in the uses selectable in the designation step S5. If these uses are previously included in the first or second use, the power management apparatus 10 may make the detailed use images I2c indicating these uses unselectable in the designation step S5 by, for example, graying them out on the display unit 13.

[0092] The second selection step S6 is a step in which the user selects one of the first to fourth revenue images I1c1 to I1c4 via the input unit 12. When one of the first to fourth revenue images I1c1 to I1c4 is selected in the second selection step S6 (S6: YES), the process returns to the first display control step S1, and the power management apparatus 10 displays on the display unit 13 a detailed revenue image I1c5 of the selected one of the first to fourth revenue images I1c1 to I1c4. For example, when the first revenue image I1c1 is selected in the second selection step S6, in the first display control step S1, a detailed revenue image I1c5 showing one of the predicted revenue and actual revenue included in the first revenue indicated by the first revenue image I1c1 and the cost of the storage battery is displayed on the display unit 13. In the second selection step S6, if any of the first to fourth revenue images I1c1 to I1c4 is not selected (S6: NO), the process returns to determining whether or not the user has issued an instruction to end the display control method (S0). If the user has issued an instruction to end the display control method (S0: YES), the above flow ends. The display control method according to this embodiment is carried out through the above steps.

[0093] As described above, the display control method and display control device according to this embodiment include a first display control step S1. In the first display control step S1, first, a first use image I1a1 indicating a first use of power by the EMS and a first revenue image I1c1 indicating a first revenue corresponding to the first use are associated and displayed on the display unit 13. Then, a second use image I1a2 indicating a second use of power by the EMS and a second revenue image I1c2 indicating a second revenue corresponding to the second use are associated and displayed on the display unit 13. This allows the user to easily understand the first use and the revenue corresponding to the first use, and the second use and the revenue corresponding to the second use. This allows users to select an appropriate use of the power generated by the EMS according to their intentions, for example, and thus to select a use that will bring in more profit when selling the power.

[0094] Furthermore, the first use is the use of the power on the following day, and the second use is the use of the power on the following day. In other words, both the first use and the second use are uses on the day after the implementation date of the display control method. This allows the user to select an appropriate use according to their intention from the uses of power by the EMS that are uses on the day after the implementation date of the display control method. Therefore, the user can make an appropriate EMS operation plan for the day after the implementation date of the display control method according to their intention.

[0095] Furthermore, one of the first use image I1a1 and the second use image I1a2 corresponds to a plurality of uses of power provided by the EMS. This allows one of the first use and the second use to be a combination of a plurality of uses. Therefore, for example, it is possible to increase the options for use of power provided by the EMS. This allows the user to more efficiently select an appropriate use of power. Furthermore, for example, the user can select a use that will result in a greater profit when selling the power.

[0096] Furthermore, in the first display control step S1, one of the first usage image I1a1 and the second usage image I1a2 is displayed on the display unit 13 in a manner that allows the user to discern that the one of the first usage image I1a1 and the second usage image I1a2 indicates multiple usages. This allows the user to understand that the one of the first usage image I1a1 and the second usage image I1a2 indicates multiple usages. This allows the user to more efficiently select an appropriate power usage.

[0097] The method also includes a first selection step S2. In the first display control step S1, one of the first-use image I1a1 and the second-use image I1a2 is displayed on the display unit 13 so as to be selectable in the first selection step S2. This allows the user to select one of the first-use image I1a1 and the second-use image I1a2 that indicates multiple uses in the first selection step S2. Therefore, for example, by the user selecting one of the first-use image I1a1 and the second-use image I1a2 in the first selection step S2, multiple uses corresponding to that one can be displayed on the display unit 13. In this case, the user can grasp the details of the multiple uses combined in the first use or the second use.

[0098] The method further includes a determination step S3 and a second display control step S4. In the determination step S3, it is determined whether or not one of the first usage image I1a1 and the second usage image I1a2 is selected in the first selection step S2. Then, in the second control step, if it is determined in the determination step S3 that one of the first usage image I1a1 and the second usage image I1a2 is selected, detailed usage images I2c indicating each of the multiple usages indicated by the one of the first usage image I1a1 and the second usage image I1a2 are displayed on the display unit 13. This allows the user to understand each of the multiple usages corresponding to the one of the first usage image I1a1 and the second usage image I1a2 by selecting the one of the first usage image I1a1 and the second usage image I1a2. This allows the user to more efficiently select an appropriate power usage.

[0099] Furthermore, in the first display control step S1, a plurality of detailed use images I2c indicating each of the multiple uses indicated by one of the first use image I1a1 and the second use image I1a2 are respectively associated with a plurality of time period images I2b indicating each of the multiple time periods, and are displayed on the display unit 13. This allows the user to understand the correspondence between each of the multiple uses and each of the multiple time periods corresponding to each of the multiple uses. This allows the user to select the use of power for each time period. This allows the user to more efficiently select an appropriate use of power.

[0100] The method further includes a designation step S5. In the designation step S5, one of the multiple time periods indicated by each of the multiple time period images I2b is designated to correspond to one of the multiple detailed use images I2c. This allows the user to associate one of the multiple uses indicated by one of the first use image I1a1 or the second use image I1a2 with one of the multiple time periods. Therefore, the user can, for example, set the use of power for each time period.

[0101] In electricity trading, the primary control reserve, secondary control reserve, tertiary control reserve (1), and capacity market transactions may be awarded before the day before the implementation date of the display control method. In this case, the content of these transactions cannot be changed on the implementation date of the display control method or the day after. Therefore, one of the multiple detailed use images I2c displayed does not include the primary control reserve, secondary control reserve, tertiary control reserve (1), and transactions in the capacity market. This makes it possible, for example, to prevent the time periods corresponding to the primary control reserve, secondary control reserve, and transactions in the capacity market from being changed in the designation step S5. This makes it possible, for example, to prevent the user from accidentally changing the details of the transaction.

[0102] Furthermore, in the first display control step S1, each of the multiple individual use images I3 indicating each of the multiple uses indicated by one of the first use image I1a1 and the second use image I1a2 is displayed on the display unit 13 in a size corresponding to the amount of power corresponding to each of the multiple individual use images I3. This allows the user to understand the amount of power corresponding to that individual use image I3 by looking at the individual use image I3.

[0103] Furthermore, in the first display control step S1, the first usage image I1a1 and the first revenue image I1c1 and the second usage image I1a2 and the second revenue image I1c2 are displayed on the display unit 13 so as to be comparable. This allows the user to compare the first usage image I1a1 and the first revenue image I1c1 with the second usage image I1a2 and the second revenue image I1c2. This allows the user to more efficiently select an appropriate power usage.

[0104] Furthermore, the first revenue or the second revenue includes the predicted revenue or the actual revenue. This allows the user to easily understand the predicted revenue or the actual revenue. Therefore, by comparing the predicted revenue with the actual revenue, the user can more effectively and efficiently select an appropriate use of electricity.

[0105] Furthermore, the first use is included among the uses of electricity selected by the user. This allows the user to select an appropriate use according to their own intentions from among the first and second uses included in the uses of electricity selected by the user. For example, the user can select an appropriate use according to their own intentions from among the first and second uses that do not include the uses of electricity that the user did not select in advance because they felt there were risks. This allows the user to more effectively select their use.

[0106] Furthermore, in the first display control step S1, a first intensity image I4c indicating the intensity of the deterioration suppression mode by the EMS of the storage battery is displayed on the display unit 13 in association with the first purpose image I1a1 and the first revenue image I1c1, and a second intensity image I4d indicating the intensity is displayed on the display unit 13 in association with the second purpose image I1a2 and the second revenue image I1c2. This allows the user to grasp the first intensity corresponding to the first purpose image I1a1 and the first revenue image I1c1, and the second intensity corresponding to the second purpose image I1a2 and the second revenue image I1c2. Therefore, it is possible to easily confirm whether the intensity of the deterioration suppression mode of the storage battery appropriately reflects the user's intention.

[0107] Furthermore, each of the first intensity image I4c and the second intensity image I4d is associated with each of the multiple time period images I2b, each indicating a multiple time period, and is displayed on the display unit 13. This allows the user to grasp the intensity of the degradation suppression mode corresponding to each of the multiple time periods.

[0108] The first revenue also includes the cost of the storage battery that can be reduced by operating the storage battery in the degradation suppression mode of the first strength, which allows the user to understand the cost of the storage battery that can be reduced by operating the storage battery in the degradation suppression mode of the first strength.

[0109] The first revenue also includes the cost of the storage battery incurred by not operating the storage battery in the degradation suppression mode of the first strength, which allows the user to grasp the cost of the storage battery incurred by not operating the storage battery in the degradation suppression mode of the first strength.

[0110] The method further includes a second selection step S6. When the first revenue image I1c1 is selected in the second selection step S6 in the first display control step S1, a detailed revenue image I1c5 showing either the predicted revenue or the actual revenue included in the first revenue indicated by the first revenue image I1c1 and the cost of the storage battery is displayed on the display unit 13. This allows the user to grasp the predicted revenue or the actual revenue and the cost of the storage battery by selecting the first revenue image I1c1.

[0111] The first use also includes trading of the electricity in an electricity market, which allows the EMS to grasp the profits generated when trading electricity in the electricity market.

[0112] The first use also includes the bilateral trading of electricity, which allows the profits generated when bilateral trading of electricity is carried out by the EMS to be ascertained.

[0113] The first use also includes controlling the amount of electricity consumed by the home, which allows the cost of electricity consumed by the home to be understood.

[0114] The first use includes either imbalance avoidance or self-consignment, which allows the user to grasp the benefit of imbalance avoidance or self-consignment using EMS.

[0115] The technical scope of the present disclosure is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present disclosure. For example, in the present embodiment, it has been described that one of the multiple detailed use images I2c displayed on the display unit 13 may not include primary control reserve, secondary control reserve, tertiary control reserve (1), and transactions in the capacity market, thereby preventing the time periods corresponding to the primary control reserve, secondary control reserve, and transactions in the capacity market from being changed in the designation step S5. However, this is not limited to this. For example, in electricity trading, if the primary control reserve, secondary control reserve, tertiary control reserve (1), and transactions in the capacity market are not sold before the day before the implementation date of the display control method, but are sold on the day before the implementation date, the multiple detailed use images I2c displayed on the display unit 13 may include the primary control reserve, secondary control reserve, tertiary control reserve (1), and transactions in the capacity market.

[0116] In addition, within the scope of the present disclosure, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modified examples may be combined as appropriate.

[0117] (Addendum) The display control method, the power management device, and the program according to the embodiment can be understood, for example, as follows.

[0118] <1> A display control method according to one embodiment of the present disclosure is characterized by comprising a first display control step of associating and displaying on a display unit a first use image indicating a first use of electricity by an EMS and a first revenue image indicating a first revenue corresponding to the first use indicated by the first use image, and also associating and displaying on the display unit a second use image indicating a second use of the electricity and a second revenue image indicating a second revenue corresponding to the second use indicated by the second use image.

[0119] The display control method includes a first display control step, in which a first use image showing a first use of power provided by the EMS and a first revenue image showing a first revenue corresponding to the first use are displayed in association with each other on the display unit, and a second use image showing a second use of power provided by the EMS and a second revenue image showing a second revenue corresponding to the second use are displayed in association with each other on the display unit. This allows the user to easily understand the first use and the revenue corresponding to the first use, and the second use and the revenue corresponding to the second use. This allows users to select an appropriate use of the power generated by the EMS according to their intentions, for example, and thus to select a use that will bring in more profit when selling the power.

[0120] <2> the above <1> In the display control method according to the present invention, the first use is a use of the power on the next day, and the second use is a use of the power on the next day.

[0121] Furthermore, the first use is the use of the power on the following day, and the second use is the use of the power on the following day. In other words, both the first use and the second use are uses on the day after the implementation date of the display control method. This allows the user to select an appropriate use according to their intention from the uses of power by the EMS that are uses on the day after the implementation date of the display control method. Therefore, the user can make an appropriate EMS operation plan for the day after the implementation date of the display control method according to their intention.

[0122] <3> the above <1> or <2> In the display control method according to the above, one of the first usage image and the second usage image may correspond to a plurality of usages of power from the EMS.

[0123] Furthermore, one of the first and second use images corresponds to a use of power by the EMS and corresponds to a plurality of uses. This allows one of the first and second uses to be a combination of a plurality of uses. Therefore, for example, it is possible to increase the options for use of power by the EMS. This allows the user to more efficiently select an appropriate use of power. Furthermore, for example, the user can select a use that will result in a greater profit when selling the power.

[0124] <4> the above <3> In the display control method according to the present invention, a configuration may be adopted in which, in the first display control step, one of the two is displayed on the display unit in a manner that makes it possible to distinguish that the one of the two indicates the multiple uses.

[0125] Furthermore, in the first display control step, one of the first and second usage images is displayed on the display unit in a manner that allows the user to distinguish that the one of the first and second usage images indicates multiple usages. This allows the user to understand that the one of the first and second usage images indicates multiple usages by looking at the one of the first and second usage images. This allows the user to more efficiently select an appropriate power usage.

[0126] <5> the above <3> The display control method according to the present invention may further include a first selection step, and may employ a configuration characterized in that, in the first display control step, the one of the two is displayed on the display unit so as to be selectable in the first selection step.

[0127] The method also includes a first selection step. In the first display control step, one of the first usage image and the second usage image is displayed on the display unit so as to be selectable in the first selection step. This allows the user to select one of the first usage image and the second usage image that indicates multiple usages in the first selection step. Therefore, for example, by the user selecting one of the first usage image and the second usage image in the first selection step, multiple usages corresponding to that one can be displayed on the display unit. In this case, the user can grasp the details of the multiple usages combined in the first usage or the second usage.

[0128] <6> the above <5> The display control method according to the present invention may further include a determination step of determining whether one of the two is selected in the first selection step, and a second display control step of displaying, on the display unit, a detailed use image indicating each of the multiple uses indicated by the one of the two, when it is determined in the determination step that the one of the two is selected.

[0129] The method further includes a determination step and a second display control step. In the determination step, it is determined whether or not one of the first and second usage images is selected in the first selection step. Then, in the second control step, if it is determined in the determination step that one of the first and second usage images is selected, detailed usage images indicating each of the multiple usages indicated by said one of the first and second usage images are displayed on the display unit. This allows the user to understand each of the multiple usages corresponding to said one of the first and second usage images by selecting said one of the first and second usage images. This allows the user to more efficiently select an appropriate power usage.

[0130] <7> the above <3> In the display control method according to the present invention, a configuration may be adopted in which, in the first display control step, a plurality of detailed use images each indicating a plurality of uses indicated by one of the devices are associated with a plurality of time zone images each indicating a plurality of time zones and displayed on the display unit.

[0131] Furthermore, in the first display control step, a plurality of detailed use images showing each of the multiple uses indicated by one of the first use image and the second use image are respectively associated with a plurality of time period images showing each of the multiple time periods, and are displayed on the display unit. This allows the user to understand the correspondence between each of the multiple uses and each of the multiple time periods corresponding to each of the multiple uses. Therefore, the user can select the use of power for each time period. Therefore, the user can more efficiently select an appropriate use of power.

[0132] <8> the above <7> The display control method according to the present invention may further include a designation step of designating one of the plurality of detailed use images to correspond to one of the plurality of time periods indicated by the plurality of time period images.

[0133] The method further includes a designation step. In the designation step, one of the multiple time periods indicated by the multiple time period images is designated to correspond to one of the multiple detailed usage images. This allows the user to associate one of the multiple usages indicated by one of the first usage image and the second usage image with one of the multiple time periods. Therefore, the user can, for example, set the usage of power for each time period.

[0134] <9> the above <8> In the display control method according to the present invention, one of the plurality of detailed usage images may be configured not to include primary control capacity, secondary control capacity, tertiary control capacity (1), and transactions in the capacity market.

[0135] In electricity trading, the primary control reserve, secondary control reserve, tertiary control reserve (1), and capacity market transactions may be awarded before the day before the implementation date of the display control method. In this case, the content of these transactions cannot be changed on the implementation date of the display control method or the day after. Therefore, one of the multiple detailed usage images displayed does not include the primary control reserve, secondary control reserve, tertiary control reserve (1), and transactions in the capacity market. This makes it possible, for example, to prevent the time periods corresponding to the primary control reserve, secondary control reserve, and transactions in the capacity market from being changed in the designation step. This makes it possible, for example, to prevent the user from accidentally changing the details of a transaction.

[0136] <10> the above <3> In the display control method according to the present invention, a configuration may be adopted in which, in the first display control step, each of a plurality of individual use images indicating each of a plurality of uses indicated by the one of the plurality of individual use images is displayed on the display unit at a size corresponding to the amount of power corresponding to each of the plurality of individual use images.

[0137] Furthermore, in the first display control step, each of the plurality of individual use images showing each of the plurality of uses indicated by one of the first use image and the second use image is displayed on the display unit in a size corresponding to the amount of power corresponding to each of the plurality of individual use images. This allows the user to understand the amount of power corresponding to each individual use image by looking at the individual use image.

[0139] In addition, in the first display control step, the first usage image and the first revenue image and the second usage image and the second revenue image are displayed on the display unit so that they can be compared. This allows the user to compare the first usage image and the first revenue image with the second usage image and the second revenue image. Therefore, the user can more efficiently select an appropriate power usage.

[0140] <12> the above <1> from <3> In the display control method according to any one of the above aspects, the first profit or the second profit may include a predicted profit or an actual profit.

[0141] Furthermore, the first revenue or the second revenue includes the predicted revenue or the actual revenue. This allows the user to easily understand the predicted revenue or the actual revenue. Therefore, by comparing the predicted revenue with the actual revenue, the user can more effectively and efficiently select an appropriate use of electricity.

[0142] <13> the above <1> from <3> In the display control method according to any one of the above aspects, the first use may be included in the uses of the power selected by a user.

[0143] Furthermore, the first use is included among the uses of electricity selected by the user. This allows the user to select an appropriate use according to their own intentions from among the first and second uses included in the uses of electricity selected by the user. For example, the user can select an appropriate use according to their own intentions from among the first and second uses that do not include the uses of electricity that the user did not select in advance because they felt there were risks. This allows the user to more effectively select their use.

[0144] <14> the above <1> from <10> In a display control method according to any one of the above embodiments, a configuration may be adopted in which, in the first display control step, a first intensity image indicating the intensity of the deterioration suppression mode by the EMS of the storage battery is displayed on the display unit in association with the first use image and the first revenue image, and a second intensity image indicating the intensity is displayed on the display unit in association with the second use image and the second revenue image.
