Mode for Carrying Out the Invention

[0009] Hereinafter, with reference to the drawings, a display control device, a display control method, and a program according to an embodiment of the present disclosure will be described. The display control device manages, for example, a plan regarding the trading of the electric power generated by the plant. At this time, the display control device displays the plan regarding the trading of the electric power in a manner that can be grasped by the user. Thereby, the user can consider and determine the plan regarding the trading of the electric power. Hereinafter, the display control device according to the present embodiment will be described.

[0010] (Display control device) FIG. 1 is a schematic block diagram showing the system configuration of a power management device 10 (display control device) according to the present disclosure. The power management device 10 is communicably 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 may be configured using a local area network (LAN). The network 70 may be configured by combining a plurality of networks.

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

[0012] Here, the plant P may be at least a part of facilities such as a water treatment facility, a production facility, a power generation facility, a storage facility, a waste treatment facility, etc. In the present embodiment, it is assumed that the plant P is a power generation facility using wind power, thermal power, hydraulic power, etc. When the plant P is a facility other than a power generation facility, the plant P may generate power secondarily by using the energy etc. generated within the plant P when fulfilling the main purpose of the plant P. For example, when the plant P includes a waste treatment facility, the plant P may generate power secondarily by using the thermal energy generated when the plant P treats waste (for example, incinerates).

[0013] The plant P may be a single plant (one facility), or may be a group of plants (multiple facilities) capable of supplying and receiving power from each other. For example, when the plant P is a group of plants, the plant P may include, in addition to at least a part of the said facilities, a solar power generation facility, a storage battery, an on-site cogeneration system, etc. When the plant P is a group of plants, the distance between the facilities in the multiple facilities is not limited, and the multiple facilities do not have to be close to each other.

[0014] The power management device 10 may consider, for example, the cost reduction effect premised on the introduction of a storage battery. In this case, the power management device 10 can, for example, charge the storage battery during the daytime when the electricity price is low, while discharging the electricity stored in the storage battery, for example, during the nighttime when the electricity price is high. Note that the electricity discharged from the storage battery may be sold to the market or consumed in the plant P. The power management device 10 may consider, for example, the cost reduction effect premised on the control of the power generation amount of the plant P. In this case, the power management device 10 can, for example, suppress the power generation amount of the plant P during the daytime when the electricity price is low, while increasing the power generation amount of the plant P, for example, during the nighttime when the electricity price is high. For example, when the plant P is a power generation facility, the power generation amount may be set to 0 by not operating the power generation facility during the daytime, and the power generation facility may be operated at the upper limit of its capacity during the nighttime so that the power generation amount is 100% of its capacity. The power management device 10 may consider, for example, the cost reduction effect premised on the adjustment of the demand amount (for example, air conditioning, etc.). For example, the power management device 10 may level the demand amount, may change the demand amount according to the electricity price, or may change the demand amount according to the supply amount.

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

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

[0017] FIG. 2 is a schematic block diagram showing a specific example of the functional configuration of the power management device 10 (display control device). The power management device 10 is configured using an information device (information processing device) such as a smartphone, a tablet, a personal computer, a dedicated device, or a server device. The power management device 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, for example, as a network interface. The communication unit 11 performs data communication with other devices via a network according to 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 (mouse, tablet, etc.), buttons, a touch panel, etc. The input unit 12 is operated by the user when inputting the user's instructions to the power management device 10. The input unit 12 may be an interface for connecting the input device to the power management device 10. In this case, the input unit 12 inputs an input signal generated in response to the user's input in the input device to the power management device 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, recognizes the words spoken by the user, and inputs the character string information of the recognition result to the power management device 10. The voice recognition process may be executed by the control unit 15. The input unit 12 may be configured in any manner as long as it can input the user's instructions to the power management device 10.

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

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

[0022] The power source information storage unit 141 stores power source information. The power source information is information regarding 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 treatment facility, a wind power generation facility, a storage battery, a cogeneration system, or the like.

[0023] Here, the information serving as the basis for calculating the power generation cost varies depending on the type of the plant P. For example, when the power source is a waste treatment facility, the information serving as the basis for calculation may be information regarding the cost of the combustion aid. The combustion aid is necessary for incinerating (burning) waste. For example, when the power source is a cogeneration system, the information serving as the basis for calculation may be information regarding the cost of fuel. Examples of the fuel include natural gas, petroleum, and LP gas. The fuel is used for power generation in the cogeneration system. When the power source is a storage battery, the information serving as the basis for 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 regarding the power price. 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 certain 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 regarding the CO2 emission price. The CO2 emission price is, for example, the cost required for CO2 emission per unit quantity. The cost may include, for example, fines imposed by a country or a local government. The CO2 emission price may be a fixed price or a variable price. When 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 the same structure as the electricity price information table.

[0026] The electricity demand information storage unit 144 stores electricity demand information. The electricity demand information is information regarding the electricity demand volume in the plant P. The plant P consumes electricity, for example, for an air conditioner or the like 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 regarding a plan formulated by the plan means 151 described later. The plan information is updated, for example, after the plan is formulated by the plan means 151. In addition to the plan information by the plan means 151 (hereinafter also referred to as "plan information at the time of EMS introduction"), the plan information storage unit 145 may store information regarding a plan in the case where EMS is not introduced (hereinafter also referred to as "plan information at the time of non-EMS introduction"). The plan information at the time of non-EMS introduction is, for example, pre-set plan information without relying on the power management device 10. The plan information at the time of non-EMS introduction may be input from the input unit 12, for example.

[0028] The performance information storage unit 146 stores performance information. The performance information is information regarding the performance controlled by the control means 152 described later. The performance information is updated, for example, after the control is implemented by the control means 152.

[0029] The control unit 15 is composed of a processor such as a CPU (Central Processing Unit) and a memory (main storage device). The control unit 15 functions as a planning means 151 and a control means 152 when the processor executes a program. Note that all or part of each function 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 above program may be recorded on a computer-readable recording medium. A computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, a semiconductor memory device (e.g., SSD: Solid State Drive), or a storage device such as a hard disk or a semiconductor memory device built into a computer system. The above program may be transmitted via a telecommunication line.

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

[0031] The planning means 151 formulates a plan regarding, for example, the use of the electric power generated by the plant P. In the present embodiment, the electric power generated by the plant P is used, for example, <1> for trading electric power in the electric power market, <2> for bilateral trading, <3> for controlling self-consumption electric power, etc. Hereinafter, the electric power generated by the plant P may be simply referred to as the generated electric power.

[0032] <1> Trading electric power in the electric power market The generated electric power is used, for example, for trading electric power in the electric power market. The trading of electric power is carried out, for example, <1-1> in the wholesale market, <1-2> in the demand-supply adjustment market, <1-3> in the capacity market.

[0033] <1-1> Wholesale market The buying and selling of electric power in the wholesale market is an example of trading electric power in the electric power market. The buying and selling of electric power in the wholesale market is carried out, for example, between the plant P and the Japan Electric Power Exchange. The wholesale market includes, for example, the spot market and the forward market. The spot market is a market where the transaction is completed on the day before the day when the actual demand and supply of electric power occur. The forward market is a market where the transaction is carried out until immediately before the actual demand and supply of electric power occur (at least within the day, for example, one hour before). <1-2> Demand-supply adjustment market The buying and selling of electric power in the demand-supply adjustment market is an example of trading electric power in the electric power market. The demand-supply adjustment market is a market for securing adjustment power for adjusting the balance between demand and supply in the electric power market. The transactions in the demand-supply adjustment market include, for example, primary adjustment power, secondary adjustment power (1), secondary adjustment power (2), tertiary adjustment power (1), and tertiary adjustment power (2). The primary adjustment power is, for example, the adjustment power for suppressing the increase or decrease of the electric frequency. The secondary adjustment power (1) and the secondary adjustment power (2) are, for example, the adjustment power for restoring the electric frequency to the reference frequency. The tertiary adjustment power (1) and the tertiary adjustment power (2) are, for example, the adjustment power for economically adjusting the demand and supply of electricity.

[0034] <1-3> Capacity market The buying and selling of electricity in the capacity market is an example of electricity trading in the electricity market. The capacity market is a market for ensuring a certain amount of electricity that can respond in case of a shortage in the electricity supply to stabilize the electricity supply-demand relationship. Transactions in the capacity market are conducted, for example, when Plant P is a thermal power plant where it is easy to adjust the power generation amount. The operator of the EMS or the customer of the operator determines, in advance by contract, the supply amount when there is a request to supply electricity to the capacity market. The request is made, for example, from a general power transmission and distribution operator to the operator of the EMS or the customer of the operator. The supply amount related to the contract is determined, for example, on an annual basis. And when there is actually a request to supply electricity to the capacity market, the EMS provides at least the amount of electricity equal to or more than the supply amount determined by the contract to the market. The request is made, for example, on the day when the electricity transaction is conducted. For this reason, the planning means 151 does not have to consider the request to supply electricity to the capacity market.

[0035] <2> Bilateral trading The generated electricity may be used, for example, in bilateral trading. The bilateral trading of electricity may be conducted, for example, between Plant P and a retail electricity business operator. In this embodiment, the bilateral trading may be, for example, the bilateral trading of renewable energy electricity. The generated electricity may be used, for example, for imbalance avoidance in electricity trading. Imbalance means that a difference occurs between the power generation plan and the power generation actual performance of electricity, or between the demand plan and the demand actual performance. Imbalance avoidance means avoiding imbalance. In this embodiment, imbalance avoidance may include imbalance avoidance corresponding to a single facility and imbalance avoidance corresponding to a plurality of facilities.

[0036] <3> Control of self-consumed electricity The generated power may be used, for example, for controlling the power consumed at home. The control of the power consumed at home may include, for example, home consumption, self-dispatch, demand response, peak shaving, and peak shifting. In such a case, the generated power may be temporarily charged in a storage battery provided in the plant P and transmitted from the storage battery as needed.

[0037] The planning means 151 examines which of the above uses to apply the generated power after adjusting the power generation amount of the plant P and the stored power amount of the storage battery of the EMS, and formulates a plan that results in higher profits. The planning means 151 first calculates, for example, the predicted amount of profit based on the predicted value of the electricity price in the use of electricity, the predicted value of the power generation amount of the solar power generation facilities etc. included in the plant P, and the predicted value of the demand for electricity in the plant P etc. The above-mentioned calculation of the predicted amount may be performed for each time period for each of the plurality of uses of electricity. For example, when there are facilities such as thermal power generation and storage batteries that can adjust the amount of electricity, the operating plan of these facilities is set so that the predicted amount of profit becomes larger in consideration of the power generation cost etc. for each time period of these facilities, and the predicted amount of profit may be calculated. Next, the planning means 151 lists several cases with large predicted amounts of profit calculated. Then, the planning means 151 proposes several combinations that are more likely to obtain profits in consideration of the prediction accuracy for each use.

[0038] The control means 152 controls the plant P based on the plan information by the planning means 151. The control means 152 may read the plan information from the plan information storage unit 145, for example. After controlling the plant P, 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, for example.

[0039] (Regarding the information displayed on the display unit) The information displayed on the display unit 13 in this embodiment will be described. FIG. 3 is a schematic diagram of the screen displayed on the display unit 13. 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 examines and determines, for example, the uses of the generated power.

[0040] Specifically, the user uses the power management device 10 to check the plan for controlling the power balance of the plant P formulated by the planning means 151 of the power management device 10. Then, the user creates a plan that appropriately reflects the user's intention based on the plan formulated by the power management device 10. The power management device 10 conducts power trading in accordance with the plan created as described above. The power management device 10 displays, for example, an interface for the user to perform such operations on the display unit 13.

[0041] As shown in FIG. 3, the power management device 10 displays a profit calculation table I1, a fluctuation prediction 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, these pieces of information are arranged without overlapping on the same screen. This enables the user to grasp these pieces of information by visually observing the display unit 13. In the example shown in FIG. 3, the profit calculation table I1 and the fluctuation prediction 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 prediction graph I2. However, the positional relationship among the profit calculation table I1, the fluctuation prediction graph I2, the individual use image I3, and the suppression mode intensity image I4 is not limited to this.

[0042] The profit calculation table I1 is a table that displays, for every 24 hours, the uses of the generated electric power and the profits corresponding to the uses in association with each other. In this profit calculation table I1, the first row at the beginning is a heading, and the rows from the second row onwards are records corresponding to the heading. In the illustrated example, the number of records is 4, and the table is provided with 5 rows in total. Alternatively, the number of records may be 5 or more, or may be 3 or less. The table may have 6 or more rows in total, or may have 3 or less rows. Each record is, for example, a plan predetermined by the power management device 10 or the user. In each plan, one or more uses are determined for each time zone. In each plan, for example, the profit for each plan is obtained. In each record, a plurality of images are displayed as information corresponding to each heading row. As shown in FIG. 3, in the profit calculation table I1, for example, an image SB for selection operation, a use image I1a, a suppression mode setting image I1b, a profit image I1c, and an actual result image I1d are displayed. Each of these images displayed in the profit calculation table I1 is included one by one in each record. In the example shown in FIG. 3, the profit calculation table I1 is provided with 5 columns, and these images are displayed one by one in each column.

[0043] The image SB for selection operation is an image that enables the user to select any one of the plurality of records displayed in the profit calculation table I1. The image SB for selection operation is, for example, a so-called toggle button. The image SB for selection operation is provided one by one for each of the plurality of records displayed from the second row onwards in the profit calculation table I1. The user selects any one of the images SB for selection operation, for example, via the input unit 12. This operation is performed, for example, in the first selection step S2 described later. In the example shown in FIG. 3, the uppermost one of the plurality of provided images SB for selection operation 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 SB for selection operation. In the example shown in FIG. 3, it means that the first use (described later) in the profit calculation table I1 is selected.

[0044] The usage image I1a is an image showing the usage of the generated power every 24 hours. Here, the usage of power may be, for example, any one of <1> power trading in the power market described above, <2> relative trading, <3> control of self-consumed power, etc., or a combination of a plurality of these usages. In the usage image I1a, for example, the usage of power is represented by the market in which the power is traded. For example, when "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 power is used only for trading in the wholesale market within 24 hours. For example, when "multiple market combination" is displayed in the usage image I1a, it means that the generated power is used for multiple usages within 24 hours. Using the generated power for multiple usages means, for example, that the usage of the generated power changes depending on the time zone within 24 hours. Alternatively, using the generated power for multiple usages may mean using the generated power for multiple usages in the same time zone.

[0045] In the present embodiment, four records are displayed in the profit calculation table I1 as described above. In other words, the first to fourth usages are displayed in the profit calculation table I1. In the example shown in FIG. 3, the usage image I1a includes a first usage image I1a1, a second usage image I1a2, a third usage image I1a3, and a fourth usage image I1a4.

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

[0047] The first usage image I1a1 is an image showing the first usage of power by the EMS. In the example shown in FIG. 3, the first usage is a multiple market combination. The second-use image I1a2 is an image showing the second use of power by the EMS. In the example shown in FIG. 3, the second use is a plurality of market combinations. In the illustrated example, the first use and the second use coincide. The fact that the first use and the second use coincide means that both the first use and the second use are a plurality of market combinations, including cases where the breakdown of the multiple uses is different. In other words, even if the first use and the second use coincide as a plurality of market combinations, the specific combinations themselves of the first use and the second use do not have to be the same. The third-use image I1a3 is an image showing the third use of power by the EMS. In the example shown in FIG. 3, the third use is the wholesale market. The wholesale market as a use means that, out of 24 hours, the generated power is used only for transactions in the wholesale market. The fourth-use image I1a4 is an image showing the fourth use of power by the EMS. In the example shown in FIG. 3, the fourth use is the supply-demand adjustment market. The supply-demand adjustment market as a use means that, out of 24 hours, the generated power is used only for transactions in the supply-demand adjustment market.

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

[0049] In the present embodiment, one of the first-use image I1a1 and the second-use image I1a2 may correspond to, for example, a use of power by the EMS that is a plurality of uses. The same applies to the third-use image I1a3 and the fourth-use image I1a4. That is, the first use to the fourth use may include a plurality of the above-described uses of power. In this embodiment, the plurality of applications included in the first to fourth applications are, for example, one application expected to have high profits or a combination of a plurality of applications expected to have higher profits selected appropriately by the planning means 151 from among the applications specified in advance by the user. The specification of the application by the user is performed, for example, by the user appropriately inputting information into the power management device 10 via the input unit 12 in advance before the display control method according to this embodiment is implemented.

[0050] The power management device 10 may display on the display unit 13 so as to be distinguishable that the first to fourth applications indicate a plurality of applications. That is, for example, as shown in FIG. 3, the power management device 10 may display a plurality of market combinations in the first application image I1a1 or the second application image I1a2. Each of the plurality of applications included in the plurality of market combinations may be selected, for example, by the planning means 151 or may be selected by the user appropriately inputting information via the input unit 12. Further, the power management device 10 may display the characters displayed in the first application image I1a1 or the second application image I1a2 in a color different from other characters or in bold.

[0051] The suppression mode setting image I1b indicates that the battery deterioration suppression mode is ON or OFF in each of the first to fourth applications. The battery deterioration suppression mode will be described later.

[0052] The profit image I1c is an image showing the predicted value of the profit corresponding to the application image I1a. In the example shown in FIG. 3, the profit image I1c includes a first profit image I1c1, a second profit image I1c2, a third profit image I1c3, a fourth profit image I1c4, and a detailed profit image I1c5. The first profit image I1c1 is an image showing the predicted value of the first profit corresponding to the first application indicated by the first application image I1a1. In the example shown in FIG. 3, the first profit is 29,000 yen. The second profit image I1c2 is an image showing the predicted value of the second profit corresponding to the second application indicated by the second application image I1a2. In the example shown in FIG. 3, the second profit is 28,000 yen. The third revenue image I1c3 is an image showing the 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 the predicted value of the 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 device 10 associates the first use image I1a1 with the first revenue image I1c1 and displays them on the display unit 13, and also associates the second use image I1a2 with the second revenue image I1c2 and displays them on the display unit 13. This enables the user to compare the first use image I1a1 and the first revenue image I1c1 with the second use image I1a2 and the second revenue image I1c2. In addition to the above, the power management device 10 may associate the third use image I1a3 with the third revenue image I1c3, and the fourth use image I1a4 with the fourth revenue image I1c4, and display them on the display unit 13 in association with each other. The first use image I1a1 to the fourth use image I1a4 each correspond to each record.

[0054] The detailed revenue image I1c5 is an image showing the details of the revenue. The detailed revenue image I1c5 is, for example, an image showing any one of the predicted revenue and the actual revenue included in each of the first revenue to the fourth revenue shown by each of the first revenue image I1c1 to the fourth revenue image I1c4, and the cost of the storage battery. Hereinafter, the detailed revenue image I1c5 related to the first revenue image I1c1 will be described as an example, but the same applies to the second revenue image I1c2 to the fourth revenue image I1c4. In the detailed revenue image I1c5, which of the first revenue image I1c1 to the fourth revenue image I1c4 it is related to is determined by which of the first to fourth uses is selected by the selection operation image SB. The detailed revenue image I1c5 shows the one related to the use corresponding to the one selected by the selection operation image SB among the first revenue image I1c1 to the fourth revenue image I1c4 displayed in the revenue calculation table I1. The detailed profit image I1c5 is an image showing, for example, either the predicted profit or the actual profit included in the first profit shown by the first profit image I1c1, and the cost of the storage battery. That is, in the present embodiment, the first profit includes the predicted profit or the actual profit. For example, when the user selects, using the input unit 12, a selection operation image SB corresponding to the first usage image I1a1 displayed on the display unit 13, the detailed profit image I1c5 corresponding to the first profit is displayed in a pop-up manner as shown in FIG. 3.

[0055] In the example shown in FIG. 3, the detailed profit image I1c5 shows, for example, the breakdown of the predicted profit from the power transaction in the predicted profit and the profit (cost of the storage battery) due to the extended life of the storage battery. The profit from the power transaction is the profit obtained by buying and selling the power generated by the plant P. The profit (cost of the storage battery) due to the extended life of the storage battery is, for example, the effect amount obtained by suppressing the deterioration of the storage battery by operating the storage battery in a deterioration suppression mode, which is a mode for suppressing its deterioration, and delaying the replacement of the storage battery. In other words, the first profit includes the cost of the storage battery that can be reduced by operating the storage battery in the deterioration suppression mode of the first intensity described later.

[0056] Alternatively, the detailed profit image I1c5 may display the cost of the storage battery that occurs when the storage battery is not operated in the deterioration suppression mode instead of the profit due to the extended life of the storage battery when the storage battery is operated in the deterioration suppression mode. In other words, the first profit may include the cost of the storage battery that occurs when the storage battery is not operated in the deterioration suppression mode of the first intensity described later. By visually observing the detailed profit image I1c5 thus displayed, the user can grasp the predicted profit or the actual profit and the cost of the storage battery.

[0057] The performance image I1d is an image showing the actual results of revenue when the generated power is used for the applications corresponding to the application image I1a. The performance information displayed in the performance image I1d is output based on past information on 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 between the predicted revenue value shown in the average revenue image I1d2 and the actual revenue value on the same day in the past for the date related to the predicted value. In the example shown in FIG. 3, for example, 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 value of the revenue on the same day in the past for the date related to the average revenue image I1d2. In the example shown in FIG. 3, for example, the average value of the revenue on the same day in the past for the date related to the first revenue image I1c1 is 30,000 yen. Four accuracy images I1d1 and four average revenue images I1d2 are provided corresponding to the first to fourth application images I1a1 to I1a4, respectively.

[0058] The fluctuation prediction graph I2 is a graph showing the predicted values of the fluctuations in price for each time zone for each power market and the predicted values of the fluctuations in power generation amount for each time zone. In the present embodiment, for example, the fluctuation prediction graph I2 corresponding to the application selected by the selection operation image SB among the revenue calculation tables I1 is displayed. In the example shown in FIG. 3, the fluctuation prediction graph I2 corresponding to the first application image I1a1 is displayed. FIG. 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 at the position of the fluctuation prediction graph I2 shown in FIG. 3 on the display unit 13. As shown in FIG. 4, a fluctuation image I2a, a time zone image I2b, and a detailed application image I2c are displayed on the fluctuation prediction graph I2.

[0059] The variable image I2a is a line graph showing the fluctuations in price or power generation volume for each electricity market. The variable image I2a shows, for example, the fluctuations in electricity price or power generation volume every 30 minutes. By visually observing the variable image I2a, the user can grasp the fluctuations in electricity price for each time zone. The variable image I2a includes a price graph I2a1 and a power generation volume graph I2a2. The price graph I2a1 shows the fluctuations in price for each time zone for each electricity market. The price graph I2a1 shows, for example, the prediction of price fluctuations every 24 hours. The vertical axis of the price graph I2a1 is the trading price of electricity. The unit of the trading price of electricity is, for example, yen / kWh in the wholesale market or imbalance market, and yen / kW in the demand-supply adjustment market. The power generation volume graph I2a2 shows the fluctuations in power generation volume for each time zone. The power generation volume graph I2a2 shows, for example, the prediction of power generation volume every 24 hours. The vertical axis of the power generation volume graph I2a2 is the unit of power generation volume (for example, kWh).

[0060] The time zone image I2b shows each of a plurality of time zones in the variable prediction graph I2. A plurality of time zone images I2b are provided along the horizontal axis in the variable prediction graph I2. In other words, the horizontal axis of the variable prediction graph I2 is time. Here, in the present embodiment, the use of the generated electricity is determined every 30 minutes. The variable prediction graph I2 shows the predicted price values every 24 hours. Therefore, in the variable prediction graph I2, 48 time zone images I2b each showing 30 minutes are provided. Alternatively, the time shown by the time zone image I2b may be any time other than 30 minutes. For example, the time zone image I2b may show 1 hour, 15 minutes, or any other arbitrary time.

[0061] The detailed use image I2c is an image showing the use of the generated electricity in the variable prediction graph I2. In the present embodiment, the detailed use image I2c shows, for example, the one corresponding to the use selected by the selection operation image SB in the profit calculation table I1. In the examples shown in FIGS. 3 and 4, the detailed use image I2c shows the one corresponding to the first use image I1a1. For example, in the example shown in FIG. 3, it shows that the generated power is used for trading in the wholesale market during the time period from 0:00 to 4:00. It shows that the generated power is used for trading in multiple markets (multiple market combinations) during the time period from 4:00 to 12:00. It shows that the generated power is used for imbalance avoidance during the time period from 12:00 to 18:00. It shows that the generated power is used for trading in the wholesale market again during the time period from 18:00 to 0:00 of the next day. By visually observing the detailed usage image I2c, the user can grasp the usage of the generated power for each time period. Also, the user may determine the usage of the generated power for each time period by operating the detailed usage image I2c via the input unit 12 (details will be described later).

[0062] The individual usage image I3 is a pie chart showing the ratio of the usage of the generated power for each time period. In the present embodiment, the individual usage image I3 shows the ratio of the usage of the generated power for each time shown by the time period image I2b. In the example shown in FIG. 3, the individual usage image I3 shows the ratio of the usage of the generated power every 30 minutes. In the present embodiment, such a pie chart corresponding to one day is composed of 48 time frames every 30 minutes. When the time period image I2b shows an arbitrary time other than 30 minutes, the time shown by the individual usage image I3 may also correspond to the time shown by the time period image I2b.

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

[0064] FIG. 5 is a first example of the individual use image I3 corresponding to a plurality of market combinations. FIG. 6 is a second example of the individual use image I3 corresponding to a plurality of market combinations. Here, in the same time period, the generated power may be used for multiple purposes. In such a case, the individual use image I3 may show each of the multiple purposes, that is, as shown in FIG. 5, in the individual use image I3 which is a pie chart, by displaying the multiple purposes by ratio, the ratio of the purposes for which the power is used can be made visible. In the example shown in FIG. 5, for example, during the time period exactly from 16:00 to 16:30, 1 / 3 of the generated power is used for trading in the wholesale market, 1 / 3 is used for the supply-demand adjustment market, and the remaining 1 / 3 is used for imbalance avoidance and others. Also, for example, as shown in FIG. 6, the individual use image I3 may be a stacked bar graph. At this time, the vertical axis of the individual use image I3 may be, for example, any one of the power amount of each market, the revenue of each market, and the revenue fluctuation risk of each market including the past accuracy variation. In the individual use image I3, the vertical axis may be displayed so as to be switchable among the above. The horizontal axis of the individual use image I3 may be time. Specifically, a plurality of time frame images I2b may be arranged 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 indicating the intensity of the deterioration suppression mode by the EMS of the storage battery. Here, the deterioration suppression mode of the storage battery is a mode for suppressing the deterioration of the storage battery by suppressing the output of the storage battery. For example, when increasing the profit by trading more power in a time zone with a relatively high power price, it is preferable to increase the output of the storage battery by lowering the intensity of the deterioration suppression mode or turning it off. When suppressing the amount of power traded or consuming the power at home in a time zone with a relatively low power price, the intensity of the deterioration suppression mode may be increased to suppress the output of the storage battery.

[0066] As shown in FIG. 3, the suppression mode intensity image I4 includes a time zone-by-time zone intensity image I4a, a time zone-by-time zone 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-by-time zone intensity image I4a (time zone image) is an image indicating the time zone in the suppression mode intensity image I4. In the example shown in FIG. 3, the time zone-by-time zone intensity image I4a shows the one corresponding to the first usage image I1a1 selected by the selection operation image SB. That is, in the example shown in FIG. 3, the time zone-by-time zone intensity image I4a shows 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 of the next day.

[0067] The time zone-by-time zone usage image I4b is an image indicating the usage of power corresponding to each of the time zones indicated by the time zone-by-time zone intensity image I4a. The time zone-by-time zone usage image I4b appropriately displays the usage of power in the corresponding time zone corresponding to each of the times displayed in the time zone-by-time zone intensity image I4a.

[0068] The first intensity image I4c is an image showing the intensity in the deterioration suppression mode corresponding to the first application image I1a1. In the present embodiment, the first intensity image I4c is associated with each of a plurality of intensity images I4a for each time zone showing a plurality of time zones and is displayed on the display unit 13. In the example shown in FIG. 3, the first intensity image I4c shows that the intensity in the deterioration suppression mode changes to Lv.7, Lv.2, Lv.7, Lv.7 as time progresses.

[0069] In the present embodiment, the intensity in the deterioration suppression mode indicates that, for example, the larger the numerical value of Lv., the stronger, and the smaller the numerical value, the weaker. Alternatively, the intensity in the deterioration suppression mode may be shown as a percentage of 0 to 100% instead of the numerical value of Lv. In this case, the intensity in the deterioration suppression mode may indicate that, for example, the smaller the numerical value of the percentage, the stronger, and the larger the numerical value, the weaker.

[0070] The second intensity image I4d, the third intensity image I4e, and the fourth intensity image I4f are all the same as the first intensity image I4c, but are different in the following points. The second intensity image I4d shows the intensity in the deterioration suppression mode corresponding to the second application image I1a2. The third intensity image I4e shows the intensity in the deterioration suppression mode corresponding to the third application image I1a3. The fourth intensity image I4f shows the intensity in the deterioration suppression mode corresponding to the fourth application 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 application to the fourth application the user selects. For example, in the example shown in FIG. 3, as described above, the first application is selected by the selection operation image SB. Therefore, in the example shown in FIG. 3, the first intensity image I4c corresponding to the first application image I1a1 is displayed. For example, when the second application is selected by the selection operation image SB, the second intensity image I4d corresponding to the second application 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 Lv. of the intensity in the deterioration suppression mode. The numerical value of the Lv. of the intensity in the deterioration suppression mode is, for example, appropriately selected and operated by the user via the input unit 12 from any of the first intensity images I4c that are displayed corresponding to each of the time zones indicated by the time zone-by-time zone intensity image I4a. When operating the intensity in the deterioration suppression mode using the intensity adjustment operation image I4g, the user selects any one of the first intensity image I4c to the 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 Lv. of the intensity of the selected one among the first intensity image I4c to the fourth intensity image I4f changes in the deterioration suppression mode. For example, the user may increase the numerical value of the Lv. of the intensity in the deterioration suppression mode by selecting the upper triangular button of the intensity adjustment operation image I4g using the input unit 12. The numerical value of the Lv. of the intensity in the deterioration suppression mode may be decreased by selecting the lower triangular button of the intensity adjustment operation image I4g. In the power management device 10 according to the present embodiment, each of the above information is displayed on the display unit 13.

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

[0073] The operations of the control unit 15 described above are stored in the auxiliary storage device 94 (storage) in the form of a program. The processor 91 reads the program from the auxiliary storage device 94, expands it in the main storage device 92, and executes the above processing according to the program. Further, the processor 91 secures a storage area corresponding to each of the above-described storage units 14 in the main storage device 92 according to 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 a part of the functions to be exhibited by the information processing apparatus 90. For example, the program may exhibit functions by combination with other programs already stored in the auxiliary storage device 94 or combination with other programs implemented in other devices. In other examples of the embodiment, the information processing apparatus 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 the PLD include a PAL (Programmable Array Logic), a GAL (Generic Array Logic), a CPLD (Complex Programmable Logic Device), and an 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, a semiconductor memory, etc. The auxiliary storage device 94 may be an internal medium directly connected to the bus of the information processing device 90, or may be an external medium connected to the information processing device 90 via the input / output interface 95 or a communication line. Also, when this program is distributed to the information processing device 90 via a communication line, the information processing device 90 that has received the distribution may expand the program in the main storage device 92 and execute the above processing. In at least one embodiment, the auxiliary storage device 94 is a non-transitory tangible storage medium.

[0076] Also, the program may be for realizing a part of the functions described above. Furthermore, the program may be a so-called difference file (difference program) that realizes the functions described above in combination with other programs already stored in the auxiliary storage device 94.

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

[0078] (Display control method) Next, the display control method according to this embodiment will be described. That is, the processing content for causing the display unit 13 to display various information by the power management device 10 will be described. FIG. 8 is a flowchart of the display control method of this embodiment. As shown in FIG. 8, the display control method according to the present 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. Each of these steps is repeatedly executed as long as the user does not give an end instruction for the display control method (S0: NO). In the following description, only the first use and the second use will be described as examples, but the display control method according to the present embodiment may be implemented including the third use and the fourth use.

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

[0080] In the present embodiment, the uses related to the first use image I1a1 and the second use image I1a2 displayed as described above may be, for example, in accordance with a plan formulated by the planning means 151. Also, the first use may be included in the use selected by the user among the uses of electric power. Here, the user may view the change image I2a of the change prediction graph I2 and consider and determine whether to include a use to be included in the first use or a use not to be included in the first use. In such a case, the user inputs, via the input unit 12, the use to be included in the first use. The planning means 151 may determine the first use based on the information input from the user in this way.

[0081] In the present embodiment, one of the first use image I1a1 and the second use image I1a2 corresponds to the use of electric power by the EMS for a plurality of uses. That is, one of the first use related to the first use image I1a1 or the second use related to the second use image I1a2 may be the use of a plurality of market combinations. The plurality of uses are, for example, those selected by the planning means 151 as appropriate from among the uses specified in advance by the user, which have high revenue or a combination with high revenue. At this time, the power management device 10 may display on the display unit 13 in a discriminable manner that one of the first usage image I1a1 and the second usage image I1a2 indicates a plurality of usages in the first display control step S1. Specifically, for example, as shown in FIG. 3, the power management device 10 may display a plurality of market combinations in the first usage image I1a1 or the second usage image I1a2. Further, 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 other characters, or in bold.

[0082] In the first display control step S1, the power management device 10 may display at least one of the first usage image I1a1 and the second usage image I1a2 on the display unit 13 so as to be selectable in the first selection step S2. Further, in the first display control step S1, the power management device 10 may cause the display unit 13 to display the first usage image I1a1 and the first profit image I1c1, and the second usage image I1a2 and the second profit image I1c2, in a comparable manner.

[0083] The first selection step S2 is a step in which the user selects one of the first usage image I1a1 and the second usage image I1a2 that indicates a plurality of usages. In the first selection step S2, one of the first usage image I1a1 and the second usage image I1a2 that indicates only one usage may be selected. The selection in the first selection step S2 is made by the user appropriately selecting any one of the selection operation images SB corresponding to each of the first usage and the second usage via the input unit 12. Hereinafter, for example, the selection of the first usage in the first selection step S2 may be referred to as the selection of the first usage image I1a1.

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

[0085] As described above, when the number of repetitions of the first selection step S2 is 0 (S2.5: NO), it returns to the first display control step S1, and each of the 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 is 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, for example, operate the ratio of the uses of the generated power by changing the ratio 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 display the suppression mode intensity image I4 on the display unit 13 in association with the profit calculation table I1. For example, when the first use image I1a1 displayed in the profit calculation table I1 is selected by the user, the power management device 10 may display the time zone-by-intensity image I4a corresponding to the first use on the display unit 13. Also, 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 profit image I1c1, or may display the second intensity image I4d on the display unit 13 in association with the second use image I1a2 and the second profit image I1c2. By this, when the user examines the details of the first use or the second use, it may be made possible to easily change the intensity of the battery degradation suppression mode.

[0087] Also, in this first display control step S1, the power management device 10 may display each of a plurality of detailed usage images I2c indicating each of the plurality of usages indicated by one of the first usage image I1a1 and the second usage image I1a2, in association with each of a plurality of time zone images I2b indicating each of a plurality of time zones, on the display unit 13. This may facilitate the user to perform the designation step S5.

[0088] As described above, when the number of repetitions of the first selection step S2 is 1 or more (S2.5: YES), the power management device 10 performs the determination step S3. The determination step S3 is a step of determining whether one of the first usage image I1a1 and the second usage image I1a2 is selected in the first selection step S2. In the present embodiment, further, in the determination step S3, it is determined that one of the first usage image I1a1 and the second usage image I1a2 is selected, and it is determined whether the user has selected a different usage from the usage selected in the previous first selection step S2. When a usage different from the usage selected in the previous first selection step S2 is selected (S3: YES), the first display control step S1 is performed again corresponding to the selected usage. When there is no change from the usage selected in the previous first selection step S2 (S3: NO), the process proceeds to the second display control step S4.

[0089] The second display control step S4 is a step of causing the display unit 13 to display a detailed usage image I2c indicating each of the plurality of usages indicated by one of the selected first usage image I1a1 and the second usage image I1a2, when it is determined in the determination step S3 that one of the first usage image I1a1 and the second usage image I1a2 is selected and there is no change in the selected usage (S3: NO). For example, when the user selects the first usage image I1a1, as shown in FIGS. 3 and 4, the power management device 10 makes a plurality of usages included in the first usage referable for each time zone in the fluctuation prediction graph I2. In the second display control step S4, a detailed usage image I2c corresponding to the selected first usage or second usage is displayed for each of the plurality of time zone images I2b displayed in the fluctuation prediction graph I2.

[0090] The specifying step S5 is a step of specifying, from among a plurality of time zones indicated by the plurality of time-zone images I2b, one to be associated with one of the plurality of detailed usage images I2c. Specifically, for example, the user selects one of the time-zone images I2b displayed a plurality of times on the fluctuation prediction graph I2, and designates one of the plurality of detailed usage images I2c, and associates one of the selected time-zone images I2b with one of the designated detailed usage images I2c. In this way, as shown in FIGS. 3 and 4, each of the plurality of time-zone images I2b and each of the plurality of detailed usage images I2c are associated with each other and displayed on the display unit 13. The specifying step S5 may be performed until one hour before the actual start of the power transaction for the time zone displayed on the display unit 13, for example.

[0091] Here, in the power transaction, the primary regulation power, the secondary regulation power, the tertiary regulation power (1), and the transaction in the capacity market may be awarded before the day before the implementation date of the display control method. In this case, the contents of these transactions cannot be changed on the implementation date of the display control method and the day after. In the present embodiment, in such a case, one of the plurality of detailed usage images I2c displayed on the display unit 13 may not include the primary regulation power, the secondary regulation power, the tertiary regulation power (1), and the transaction in the capacity market. That is, the power management device 10 may not include the primary regulation power, the secondary regulation power, the tertiary regulation power (1), and the transaction in the capacity market in the selectable usages in the specifying step S5. If these usages are included in the first usage or the second usage in advance, in the specifying step S5, the power management device 10 may make the detailed usage images I2c indicating these usages unselectable by graying out or the like on the display unit 13.

[0092] The second selection step S6 is a step in which the user selects any one of the first to fourth revenue images I1c1 to I1c4 via the input unit 12. In the second selection step S6, when any one of the first to fourth revenue images I1c1 to I1c4 is selected (S6: YES), the process returns to the first display control step S1, and the power management device 10 causes the display unit 13 to display the detailed revenue image I1c5 of the selected one among the selected 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 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. In the second selection step S6, when none of the first to fourth revenue images I1c1 to I1c4 is selected (S6: NO), the process returns to the determination of whether or not the user has given an instruction to end the display control method (S0). When the user gives an instruction to end the display control method (S0: YES), the above flow ends. By the above steps, the display control method according to the present embodiment is implemented.

[0093] As described above, according to the display control method and the display control device according to the present embodiment, the first display control step S1 is provided. In the first display control step S1, first, the first use image I1a1 showing the first use of power by the EMS and the first revenue image I1c1 showing the first revenue corresponding to the first use are associated and displayed on the display unit 13. Then, the second use image I1a2 showing the second use of power by the EMS and the second revenue image I1c2 showing the second revenue corresponding to the second use are associated and displayed on the display unit 13. Thereby, the user can easily grasp the first use and the revenue corresponding to the first use, and the second use and the revenue corresponding to the second use. Thus, the user can, for example, select an appropriate use according to the intention from among the uses of power by the EMS. Therefore, for example, the user can select a use that results in a greater revenue when selling electricity.

[0094] Also, the first use is for the next day's power, and the second use is for the next day's power. That is, both the first use and the second use are for the day after the implementation date of the display control method. Thereby, the user can select an appropriate use according to the intention from among the uses of the power by the EMS on the day after the implementation date of the display control method. Therefore, the user can make the operation plan of the EMS on the day after the implementation date of the display control method appropriate according to the intention.

[0095] Also, one of the first use image I1a1 and the second use image I1a2 is for the use of power by the EMS and corresponds to a plurality of uses. Thereby, one of the first use and the second use can be a combination of a plurality of uses. Thus, for example, the options for the use of power by the EMS can be increased. By this, the user can more efficiently select an appropriate use of power. Also, the user can select, for example, a use that results in a greater profit when selling electricity.

[0096] Also, 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 distinguishable that the one indicates a plurality of uses. Thereby, the user can grasp that the one indicates a plurality of uses by looking at one of the first use image I1a1 and the second use image I1a2. Thus, the user can more efficiently select an appropriate use of power.

[0097] Further, it includes a first selection step S2. In the first display control step S1, one of the first usage image I1a1 and the second usage image I1a2 is selectively displayed on the display unit 13 in the first selection step S2. Thereby, the user can select, in the first selection step S2, one of the first usage image I1a1 and the second usage image I1a2 that indicates a plurality of usages. Thus, for example, when the user selects one of the first usage image I1a1 and the second usage image I1a2 in the first selection step S2, a plurality of usages corresponding to the one can be displayed on the display unit 13. In this case, the user can grasp the details of the plurality of usages combined in the first usage or the second usage.

[0098] Furthermore, it further includes a determination step S3 and a second display control step S4. In the determination step S3, it is determined whether one of the first usage image I1a1 and the second usage image I1a2 is selected in the first selection step S2. And in the second control step, when 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 each indicating a plurality of usages indicated by the one are displayed on the display unit 13. Thereby, the user can grasp each of the plurality of usages corresponding to the one by selecting one of the first usage image I1a1 and the second usage image I1a2. Thus, the user can more efficiently select an appropriate power usage.

[0099] Also, in the first display control step S1, a plurality of detailed usage images I2c each indicating a plurality of usages indicated by one of the first usage image I1a1 and the second usage image I1a2 are respectively associated with a plurality of time zone images I2b each indicating a plurality of time zones, and are displayed on the display unit 13. Thereby, the user can grasp the correspondence between each of the plurality of usages and each of the plurality of time zones corresponding to each of the plurality of usages. Thus, the user can select the power usage for each time zone. Thus, the user can more efficiently select an appropriate power usage.

[0100] Furthermore, it further includes a specified step S5. In the specified step S5, from among the plurality of time zones indicated by each of the plurality of time zone images I2b, what corresponds to one of the plurality of detailed use images I2c is specified. As a result, the user can associate one of the plurality of uses indicated by one of the first use image I1a1 and the second use image I1a2 with one of the plurality of time zones. Therefore, the user can, for example, set the use of electric power for each time zone.

[0101] Here, in the electricity transaction, the primary frequency control power, secondary frequency control power, tertiary frequency control power (1), and transactions in the capacity market may be awarded before the day before the implementation date of the display control method. In this case, the details of these transactions cannot be changed on the implementation date of the display control method and the day after. Therefore, one of the plurality of detailed use images I2c to be displayed does not include the primary frequency control power, secondary frequency control power, tertiary frequency control power (1), and transactions in the capacity market. As a result, for example, in the specified step S5, it is possible to prevent the time zones corresponding to the primary frequency control power, secondary frequency control power, and transactions in the capacity market from being changed. Therefore, for example, it is possible to prevent the user from accidentally changing the details of the transaction.

[0102] Also, in the first display control step S1, each of the 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 is displayed on the display unit 13 in a size corresponding to the amount of electric power corresponding to each of the plurality of individual use images I3. As a result, the user can grasp the amount of electric power corresponding to the individual use image I3 by looking at the individual use image I3.

[0103] Also, in the first display control step S1, the first usage image I1a1 and the first profit image I1c1, and the second usage image I1a2 and the second profit image I1c2 are displayed on the display unit 13 so as to be comparable. Thereby, the user can compare the first usage image I1a1 and the first profit image I1c1 with the second usage image I1a2 and the second profit image I1c2. Therefore, the user can more efficiently select an appropriate use of electric power.

[0104] Also, the first profit or the second profit includes a predicted profit or an actual profit. Thereby, the user can easily grasp the predicted profit or the actual measured profit. Therefore, the user can more effectively and efficiently select an appropriate use of electric power by comparing the predicted profit with the actual measured profit.

[0105] Also, the first usage is included in the usage of electric power selected by the user. Thereby, the user can select an appropriate usage according to his or her intention from among the first usage and the second usage included in the usage of electric power selected by himself or herself. For example, the user can select an appropriate usage according to his or her intention from among the first usage and the second usage that do not include the usage of electric power that he or she felt risky and did not select in advance. Therefore, the user can more effectively select a usage.

[0106] Also, 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 usage image I1a1 and the first profit image I1c1, and a second intensity image I4d indicating the intensity is displayed on the display unit 13 in association with the second usage image I1a2 and the second profit image I1c2. Thereby, the user can grasp the first intensity corresponding to the first usage image I1a1 and the first profit image I1c1 and the second intensity corresponding to the second usage image I1a2 and the second profit 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] In addition, each of the first intensity image I4c and the second intensity image I4d is associated with each of a plurality of time zone images I2b each indicating a plurality of time zones and is displayed on the display unit 13. Thereby, the user can grasp the intensity of the deterioration suppression mode corresponding to each of the plurality of time zones.

[0108] In addition, the first profit includes the cost of the storage battery that can be reduced by operating the storage battery in the deterioration suppression mode of the first intensity. Thereby, the user can grasp the cost of the storage battery that can be reduced by operating the storage battery in the deterioration suppression mode of the first intensity.

[0109] In addition, the first profit includes the cost of the storage battery that occurs when the storage battery is not operated in the deterioration suppression mode of the first intensity. Thereby, the user can grasp the cost of the storage battery that has occurred due to not operating the storage battery in the deterioration suppression mode of the first intensity.

[0110] In addition, it further includes a second selection step S6. And in the first display control step S1, when the first profit image I1c1 is selected in the second selection step S6, a detailed profit image I1c5 showing either the predicted profit or the actual profit included in the first profit shown by the first profit image I1c1 and the cost of the storage battery is displayed on the display unit 13. Thereby, the user can grasp the predicted profit or the actual profit and the cost of the storage battery by selecting the first profit image I1c1.

[0111] In addition, the first use includes the transaction of the electric power in the electric power market. Thereby, the profit at the time of conducting the transaction of the electric power in the electric power market by the EMS can be grasped.

[0112] In addition, the first use includes the relative transaction of the electric power. Thereby, the profit at the time of conducting the relative transaction of the electric power by the EMS can be grasped.

[0113] In addition, the first use includes the control of the self-consumption electric power. Thereby, the effective amount at the time of consuming the electric power for self-consumption by the EMS can be grasped.

[0114] In addition, the first use includes either imbalance avoidance or self-delivery. Thereby, the effect amount when performing imbalance avoidance or self-delivery by EMS can be grasped.

[0115] Note that 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, among the plurality of detailed use images I2c displayed on the display unit 13, one of them is made not to include the primary adjustment force, the secondary adjustment force, the tertiary adjustment force (1), and the transaction in the capacity market. Thus, in the designation step S5, it has been described that the time zones corresponding to the primary adjustment force, the secondary adjustment force, and the transaction in the capacity market may not be changed, but the present invention is not limited thereto. For example, in the power transaction, the primary adjustment force, the secondary adjustment force, the tertiary adjustment force (1), and the transaction in the capacity market are not awarded before the day before the implementation date of the display control method. For example, in the case where they are awarded on the day before the implementation date, the primary adjustment force, the secondary adjustment force, the tertiary adjustment force (1), and the transaction in the capacity market may be included in the plurality of detailed use images I2c displayed on the display unit 13.
