DETAILED DESCRIPTION OF THE INVENTION

[0009] (Power management system 100) FIG. 1 is a schematic block diagram showing the system configuration of a power management system 100 according to the present disclosure. The power management system 100 includes a display control device 10, a planning device 20, and a control device 30. The display control device 10, the planning device 20, and the control device 30 are communicatively connected 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.

[0010] The power management system 100 performs processing related to an EMS (Energy Management System). For example, if the target of the EMS is a single factory, the EMS can be applied to, for example, efficient operation (e.g., optimal operation) of factory demand, power generation by a generator, and charging and discharging of a storage battery. Furthermore, if the target of the EMS is a power storage station or a power plant, the EMS can be applied to, for example, efficient operation (e.g., optimal operation) of a storage battery (demand when charging, supply when discharging). For example, if the target of the EMS is a power source and consumers in a specific area, the EMS can be applied to efficient operation (e.g., optimal operation) of the amount of power demand and supply in that area. Introducing an EMS can, for example, improve the efficiency (e.g., optimize) of each of the above-mentioned operations. As a result, it may be possible to reduce costs compared to not introducing an EMS.

[0011] The power management system 100 considers the cost reduction effect assuming the introduction of a storage battery, for example. In this case, the power management system 100 can, for example, charge the storage battery with power during the day when the price of electricity is low, and discharge the power stored in the storage battery during the night when the price of electricity is high.

[0012] The power management system 100, for example, formulates a power plan (plan of demand, supply, sale, purchase, etc.) for a predetermined combination (hereinafter simply referred to as a combination) of power source (power supply) and demand (power demand), and controls, for example, the power source based on the plan. The power source includes, for example, a plurality of storage batteries (a first storage battery and a second storage battery). The power source includes, for example, a power generation facility in addition to the storage batteries. The power generation facility includes, for example, a waste disposal facility, a solar power generation facility, a wind power generation facility, etc. The power management system 100 may control not only a power source that supplies power, but also a demand facility that demands power. The demand facility is, for example, a facility that uses power. The demand facility includes, for example, a plant, etc. Note that a storage battery functions as both a power source and a demand facility. In other words, when a storage battery discharges, it functions as a power source, and when a storage battery charges, it can be said that it is apparently using power, and therefore functions as a demand facility.

[0013] The user of the power management system 100 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 power source or the demand facility, or a corporation that manages the power source or the demand facility. The power source and the demand facility may be located on the same premises. The power source may be a so-called on-site power generation facility.

[0014] (Planning device 20, control device 30) The planning device 20 creates a power plan. The control device 30 controls power sources and demand facilities based on the plan created by the planning device 20. The planning device 20 and the control device 30 are configured using information devices (information processing devices) such as smartphones, tablets, personal computers, dedicated devices, and server devices.

[0015] The planning device 20, for example, creates a plan that optimizes a predetermined objective variable in a combination. The objective variable may be, for example, cost or environmental load (e.g., CO2 emissions). When the objective variable is cost, the planning device 20 creates a plan that achieves cost optimization for the entire combination. For example, machine learning artificial intelligence may be implemented in the planning device 20, and this artificial intelligence may create the plan.

[0016] The planning device 20 acquires power selling price information, power purchasing price information, power demand information, and adjustment capacity information in order to create a plan. The planning device 20 creates a plan based on each of these pieces of information. Each of these pieces of information may be stored in the planning device 20, may be directly input to the planning device 20, or may be acquired from outside via the network 70, for example.

[0017] The power selling price information is information about the power selling price at each time (each unit period). The power purchasing price information is information about the power purchasing price at each time (each unit period). The unit periods for the power selling price information and the power purchasing price information may be, for example, 30 minutes, one hour, one day, one month, 10 minutes, or one minute. The power selling price information and the power purchasing price information may be, for example, predicted prices for each hour in the power market. The power market is a market where power is traded, such as the Japan Electric Power Exchange (JEPX). The power market may be, for example, a spot market or a supply and demand adjustment market. The power price may take into account subsidies from the national or local government. When the power selling price and the power purchasing price are equal, the power selling price information and the power selling price information may be combined into one, for example, as power price information or market price information.

[0018] The power demand information is information about the power demand at each time (each unit period). The unit period of the power demand information may be, for example, 30 minutes, one hour, one day, one month, 10 minutes, or one minute. The power demand may be, for example, the power demand in the combination. The power demand may be, for example, an actual value for any past year (for example, last year). The power demand may be, for example, an average value of actual values ​​for any past several years. The power demand information may be, for example, a result of a simulation using software. The power demand information may be, for example, a result generated by artificial intelligence. The power demand information may be, for example, input by a user.

[0019] Adjustment capacity information is information related to adjustment capacity. Adjustment capacity information is, for example, information related to adjustment capacity that has been publicly solicited in the supply and demand adjustment market. Adjustment capacity information is, for example, information related to the conditions of the adjustment capacity that has been publicly solicited (for example, the period, amount of power, and rate). Examples of adjustment capacity include primary adjustment capacity, secondary adjustment capacity (secondary adjustment capacity (1), secondary adjustment capacity (2)), and tertiary adjustment capacity (tertiary adjustment capacity (1), tertiary adjustment capacity (2)).

[0020] The planning device 20 creates an electric power plan that optimizes the objective variable based on the above-mentioned information. For example, when the objective variable is cost, the planning device 20 creates plans for the supply amount (amount of power generation), the amount of power sold, and the amount of power purchased that optimize costs while satisfying power demand. More specifically, the planning device 20 may create, for example, a power generation plan by a power generation facility, an operation plan (charge / discharge amount plan) for a rechargeable battery, a sales plan for surplus power, and a purchase plan for power shortages. When the planning device 20 determines that costs can be optimized by bidding in a public solicitation for adjustment capacity, it may create a plan assuming that the bid for adjustment capacity will be successful. In this way, when assuming that the bid for adjustment capacity will be successful, the planning device 20 may create a plan assuming that the adjustment capacity will be activated, or may create a plan that does not assume that the adjustment capacity will be activated.

[0021] The planning device 20, for example, periodically creates a power plan. The planning device 20 may create a power plan, for example, once a day at a set time (for example, a predetermined time in the morning). In this case, the planning device 20 may create a plan for a set period including the next day (for example, the next week, the next 10 days, or the next month including the next day).

[0022] The planning device 20 generates information about the created plan (hereinafter also referred to as plan information) and sends the plan information to the display control device 10 and the control device 30. The planning device 20 may send the plan information to the display control device 10 and the control device 30, for example, every time a plan is created. In the following, the plan created by the planning device 20 will also be referred to as a plan created by the EMS.

[0023] The control device 30 controls power sources and demand facilities based on the planning information acquired from the planning device 20. However, when the planning device 20 creates a plan assuming the activation of adjustment capacity but the adjustment capacity is not activated, the control device 30 modifies the plan based on the planning information acquired from the planning device 20 in accordance with the adjustment capacity that was not activated, and controls the power sources and demand facilities. On the other hand, when the planning device 20 creates a plan not assuming the activation of adjustment capacity but the adjustment capacity is activated, the control device 30 modifies the plan based on the planning information acquired from the planning device 20 in accordance with the activated adjustment capacity, and controls the power sources and demand facilities. The control device 30 may determine whether or not adjustment capacity will be activated based on, for example, an input from a user, or may determine based on a signal (e.g., a signal indicating the presence or absence of an activation command) received from an external device via the network 70. The control device 30 may send information about the modified plan (hereinafter, “modification information”) to the display control device 10 and the planning device 20. The plan may be changed by the planning device 20, and in this case, the planning device 20 may send change information to the display control device 10 and the control device 30.

[0024] (Display control device 10) 2 is a schematic block diagram showing a specific example of the functional configuration of the display control device 10. The display control device 10 is configured using an information device (information processing device) such as a smartphone, tablet, personal computer, dedicated device, or server device. The display control device 10 includes a communication unit 11, an input unit 12, an output unit 13, a storage unit 14, and a control unit 15.

[0025] 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.

[0026] 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 a user when inputting the user's instructions to the display control device 10. The input unit 12 may be an interface for connecting the input device to the display control device 10. In this case, the input unit 12 inputs an input signal generated in the input device in response to the user's input to the planning device 20. 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 display control device 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 the user's instructions to the display control device 10.

[0027] The output unit 13 outputs information in a form that can be recognized by the user. The output unit 13 may be, for example, an image display device (display unit) such as a liquid crystal display or an organic EL (Electro Luminescence) display. The output unit 13 may be an interface for connecting the image display device to the display control device 10. In this case, the output unit 13 generates a video signal for displaying image data and outputs the video signal to the image display device connected to the output unit 13. The output unit 13 may be a device for outputting audio such as a speaker. The output unit 13 may be an interface for connecting an audio output device such as a speaker or headphones to the display control device 10. In this case, the output unit 13 generates an audio signal for playing audio data and outputs the audio signal to the audio output device connected to the output unit 13. The output unit 13 may be, for example, a printer. The output unit 13 may be an interface for connecting a printer to the display control device 10. In this case, the output unit 13 generates a print signal for printing print data and outputs the print signal to the printer connected to the output unit 13. The output unit 13 may be configured as a touch panel integrated with the input unit 12. In this embodiment, the output unit 13 is an image display device (display unit), and functions as a display unit 13a.

[0028] 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.

[0029] The control unit 15 is configured using a processor such as a CPU (Central Processing Unit) and a memory (main storage device). When the processor executes a program, the control unit 15 functions as an image source information acquisition means 151, an image generation means 152, a first display control means 153, a second display control means 154, an adjustment reserve bid success determination means 155, an adjustment reserve activation determination means 156, a plan modification determination means 157, and a plan confirmation determination means 158. Note that 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 above program may be recorded on a computer-readable recording medium. Examples of computer-readable recording media include portable media such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, and a semiconductor storage device (e.g., a solid-state drive (SSD)), as well as storage devices such as a hard disk or semiconductor storage device built into a computer system. The above program may be transmitted via a telecommunications line.

[0030] The control unit 15 may execute, for example, an application installed on its own device (the display control device 10). A specific example of such an application is an application provided to the display control device 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 on the display control device 10, or may be downloaded each time a determination process is executed. For example, when implemented as a web browser application, the display control device 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 display control device 10 connecting to the web server. The control unit 15 operates according to the program of the application being executed.

[0031] The image source information acquisition means 151 acquires information that is the source of the image generated by the image generation means 152. The image source information means acquires, for example, plan information generated by the planning device 20. The image source information means may acquire, for example, plan source information that is the source of the plan information from the planning device 20. Examples of the plan source information include electricity selling price information, electricity purchasing price information, and electricity demand information. Note that these pieces of information may be stored in advance in the storage unit 14, and in that case, the image source information acquisition means 151 may acquire each piece of information from the storage unit 14.

[0032] FIG. 3 is a schematic block diagram showing a specific example of the functional configuration of the image generating means 152. The image generation means 152 generates an image based on the information acquired by the image source information acquisition means 151. The image generation means 152 includes, for example, an operation plan image generation means 152a, a state-of-charge image generation means 152b, an adjustment capacity image generation means 152c, a power selling price image generation means 152d, a power purchasing price image generation means 152e, a power generation amount image generation means 152f, and a power demand image generation means 152g. Each of these image generation means 152 will be described below together with a screen (hereinafter also referred to as a review screen) on which a specific image generated by each of these image generation means 152 is displayed.

[0033] FIG. 4 is a first example of the review screen displayed by the first display control means 153. FIG. 5 is a second example of the review screen displayed by the first display control means 153. FIG. 6 is a third example of the review screen displayed by the first display control means 153. FIG. 7 is a fourth example of the review screen displayed by the first display control means 153. FIG. 8 is a fifth example of the review screen displayed by the first display control means 153. FIG. 9 is a sixth example of the review screen displayed by the first display control means 153. 4 to 9 are based on planning information that does not assume the activation of control reserves. A consideration screen based on planning information that assumes the activation of control reserves will be described later.

[0034] The operation plan image generating means 152a generates an operation plan image 41 (charge / discharge amount image 48) as shown in FIGS. 4 to 9 based on, for example, plan information. The operation plan image 41 is an image related to an operation plan (charge / discharge plan) for a storage battery. The operation plan image 41 may be represented in a graph format as shown in FIGS. 4 to 7, or in a table format as shown in FIG. 9. As shown in FIGS. 4 to 7, the operation plan image 41 may be, for example, a line graph in which the horizontal axis indicates time and the vertical axis indicates the charge / discharge amount. As shown in FIG. 9, the operation plan image 41 may be, for example, a table including a plurality of records indicating a start time, an end time, and a charge / discharge amount. Note that in the illustrated example, in the operation plan image 41, a positive charge / discharge amount indicates discharging, and a negative charge / discharge amount indicates charging, but this is not limited thereto.

[0035] The charge state image generating means 152b generates a charge state image 42 (charge / discharge amount image 48) as shown in Figs. 4 to 7, for example, based on the plan information. The charge state image 42 is an image related to the charge / discharge state of the storage battery. The charge / discharge state of the storage battery may be determined based on the operation plan of the storage battery. For example, if there is an operation plan for a 0 MWh rechargeable battery to be charged at 10 MWh for three hours, the charge state of the rechargeable battery after charging will be +30 MWh. The charge state image 42 may be, for example, a line graph in which the horizontal axis indicates time and the vertical axis indicates the charge / discharge amount.

[0036] The control capacity image generating means 152c generates a control capacity image 43 (reason image 49) as shown in FIGS. 4 to 7 based on, for example, the plan information. The control capacity image 43 is an image related to control capacity. The control capacity image 43 indicates, for example, a time period and the type of control capacity (power use) for that time period. The control capacity image 43 includes a time period display section 43a and a use display section 43b. The time period display section 43a may include, for example, a line diagram (e.g., multiple lines or a plane figure) indicating the time period (time range). The use display section 43b may include a message (e.g., "provision of primary control capacity") indicating the type of control capacity (power use). In the illustrated example, the control capacity image 43 indicates that "provision of primary control capacity" is scheduled between 3:00 and 6:00.

[0037] The power generation amount image generating means 152f generates a power generation amount image 44 (reason image 49) as shown in Figs. 6 and 8, for example, based on the plan information. The power generation amount image 44 is an image related to the operation plan (power generation amount) of the power generation facility. The power generation amount image 44 may be, for example, a line graph in which the horizontal axis indicates time and the vertical axis indicates the power generation amount. The power generation amount image 44 may be displayed on the display unit 13a together with a power demand image 47, which will be described later, as shown in Fig. 8, or may be displayed on the display unit 13a separately from the power demand image 47, as shown in Fig. 6.

[0038] The power selling price image generating means 152d generates a power selling price image 45 (reason image 49) as shown in FIG. 4, for example, based on the power selling price information. The power selling price image 45 is an image related to the power selling price at each time. The power selling price image 45 may be, for example, a line graph in which the horizontal axis indicates time and the vertical axis indicates the power selling price. In the example shown, the power selling price image 45 also shows a base price image 45a. The base price image 45a is an image indicating the base price. The base price image 45a is displayed superimposed on the power selling price image 45 (as part of the power selling price image 45). The base price is, for example, the cost of power generation. In this case, if the power selling price is higher than the base price, a profit can be made by selling power. The base price may be stored in, for example, the memory unit 14. However, the base price image 45a is not necessary. The power purchase price image generating means 152e generates a power purchase price image 46 (reason image 49) as shown in FIG. 5, for example, based on the power purchase price information. The power purchase price image 46 is an image relating to the power purchase price at each time. The power purchase price image 46 may be, for example, a line graph in which the horizontal axis indicates time and the vertical axis indicates the power purchase price. The power purchase price image 46 may also display the base price image 45a. However, the base price image 45a may not be present.

[0039] If the power selling price information and the power purchasing price information are combined into one information, such as power price information and market price information, the image generating means 152 may generate a power price image (market price image). The market price image is an image related to the market price of power at each time. The power selling price image 45, the power purchasing price image 46, and the market price image may be displayed for each market. For example, the power selling price image 45, the power purchasing price image 46, and the market price image may be provided separately for the spot market and the balancing market.

[0040] The power demand image generating means 152g generates a power demand image 47 (reason image 49) as shown in Figs. 7 and 8, for example, based on the power demand information. The power demand image 47 is an image relating to the power demand at each time. The power demand image 47 may be, for example, a line graph in which the horizontal axis indicates time and the vertical axis indicates power demand. The power demand image 47 may be displayed on the display unit 13a together with the power generation amount image 44, as shown in Fig. 8, or may be displayed on the display unit 13a separately from the power generation amount image 44, as shown in Fig. 7.

[0041] Here, of the above-mentioned images, the operation plan image 41 and the charging status image 42 function as the charging / discharging amount image 48, and the adjustment capacity image 43, the power generation amount image 44, the electricity selling price image 45, the electricity purchasing price image 46, and the electricity demand image 47 function as the reason image 49. The charge / discharge amount image 48 is an image that shows a future first time slot and the charge / discharge amount of the first storage battery planned by the EMS, which is the charge / discharge amount for the first time slot. In the present embodiment, if both the operation plan image 41 and the charge state image 42 are in a graph format as shown in Figs. 4 to 7, the horizontal axis indicates the time slot (first time slot) and the vertical axis indicates the charge / discharge amount for the corresponding time slot (first time slot). If the operation plan image 41 is in a table format as shown in Fig. 9, the start time and end time of each record indicate the time slot (first time slot), and the charge / discharge amount of each record indicates the charge / discharge amount for the corresponding time slot (first time slot).

[0042] The reason image 49 is an image corresponding to the reason for the charge / discharge amount (the amount of charge / discharge in the first time slot) corresponding to the charge / discharge amount image 48. By checking the reason image 49, the user may be able to understand the reason for the amount of charge / discharge in the first time slot. The reason image 49 includes, for example, a power usage image 50. The power usage image 50 is an image showing a future second time slot and a power usage planned by the EMS that corresponds to the second time slot. In this embodiment, the adjustment capacity image 43 of the reason image 49 shows the time slot (time slot display section 43a) and the usage corresponding to the time slot (usage display section 43b), as shown in FIGS. 4 to 7, and therefore functions as the power usage image 50. The power usage includes adjustment capacity. The first time slot and the second time slot may be different time slots or may be the same time slot.

[0043] The power use indicated by the power use image 50 is not limited to adjustment capacity. The power use may be, for example, any use of electricity excluding self-consumption. In this case, the power use may be, for example, trading in a wholesale electricity market, trading in a supply and demand balancing market, etc. Furthermore, in this case, the power use may be, for example, information indicating in which market the power will be traded. The power usage may be a usage of power including self-consumption. In this case, when the power demand image 47 indicates the power demand for self-consumption, the power demand image 47 functions as a power usage image 50. However, the reason image 49 is not limited to the power usage image 50, and as described above, the reason image 49 may include the power generation amount image 44, the power selling price image 45, the power purchasing price image 46, the power demand image 47, etc. The reason image 49 may include, for example, an image showing the power price in the wholesale power market, an image showing the price in the supply and demand balancing market, and an image showing the power usage (for example, in which market the power is traded). The function of the reason image 49 for the adjustment capacity image 43, the power generation amount image 44, the power selling price image 45, the power purchasing price image 46, and the power demand image 47 will be described later.

[0044] 4 to 8, the first display control means 153 causes the display unit 13a to display both the charge / discharge amount image 48 and the reason image 49. This allows the user to easily understand the reason for the charge / discharge amount corresponding to the first future time slot. This makes it easier for the user to understand, for example, the validity of the charge / discharge plan for the storage battery by the EMS. Below, a specific example of the review screen displayed by the first display control means 153 will be described.

[0045] For example, in the first example consideration screen shown in Fig. 4, the first display control means 153 causes the display unit 13a to display an operation plan image 41 and a charge state image 42 as a charge / discharge amount image 48. The first display control means 153 causes the display unit 13a to display an adjustment capacity image 43 (power use image 50) and a power selling price image 45 as a reason image 49. At this time, the first display control means 153 causes the display unit 13a to display the charge / discharge amount image 48 and the reason image 49 in association with each other. This allows the user to more easily understand the charge / discharge amount image 48 and the reason image 49 corresponding to this charge / discharge amount image 48. Hereinafter, the manner in which the charge / discharge amount image 48 and the reason image 49 are associated with each other will be specifically described for each type of reason image 49.

[0046] Among the reason images 49 in the first example, the power selling price image 45, like the operation plan image 41 and the charging state image 42, is in a graph format with the horizontal axis representing the time axis (reference axis). The first display control means 153 aligns the horizontal axes of these images and arranges them vertically, thereby displaying these images in association with each other on the display unit 13a. In the illustrated example, the horizontal axes of the operation plan image 41, the charging state image 42, and the power purchasing price image 46 indicate the 24-hour period of the most recent day (e.g., the day after the day the plan was created) in the created plan. Furthermore, these horizontal axes are aligned horizontally. In the illustrated example, an auxiliary line 51 is provided vertically across each of these images, but this auxiliary line 51 may be omitted. Note that multiple auxiliary lines 51 are provided at equal intervals along the time axis. Note that the power selling price image 45 can be said to be an image showing the third time slot and the power selling price corresponding to the third time slot. The first time slot and the third time slot described above may be the same time slot or different time slots.

[0047] Among the reason images 49 in the first example, the first display control means 153 displays the adjustment capacity image 43 in the time period indicated by the adjustment capacity image 43 (second time period) among the time periods indicated by the time axes of the operation plan image 41 and the charge state image 42 (charge / discharge amount image 48), thereby causing these images to be displayed in association on the display unit 13a. In the example shown, the adjustment capacity image 43 is associated not only with the operation plan image 41 and the charge state image 42 (charge / discharge amount image 48), but also with the power selling price image 45 (reason image 49). Note that in this embodiment, the adjustment capacity image 43 is superimposed on at least one of the operation plan image 41 and the charge state image 42 (charge / discharge amount image 48) (in the example shown, the charge state image 42), and the first display control means 153 displays the charge / discharge amount image 48 and the adjustment capacity image 43 (reason image 49) in an overlapping manner. Therefore, the user can view, in a narrow field of view, the charge / discharge amount image 48 and the reason image 49 superimposed on the charge / discharge amount image 48. This makes it possible to more easily grasp the charge / discharge amount image 48 and the reason image 49.

[0048] According to this first example consideration screen, the user can compare the charge / discharge amount image 48 with the reason image 49 to determine and confirm the validity of the charge / discharge plan for the next day proposed (planned) by the EMS.

[0049] For example, the operation plan image 41 and the charge status image 42 display that the storage battery is charging 30 MWh from midnight to 3:00 (first time slot). Furthermore, the control capacity image 43 displays that the storage battery will be contributed to the primary control capacity as an electric power use from 3:00 to 6:00 (second time slot different from the first time slot). Therefore, from these displays on the display unit 13a, the user can easily understand that the reason for charging from midnight to 3:00 is to prepare for contributing to the primary control capacity from 3:00 to 6:00. For example, the operation plan image 41 and the charge state image 42 display that the storage battery is on standby from 3:00 to 6:00 (first time slot) without charging or discharging. Furthermore, the control capacity image 43 displays that the storage battery will be contributed to the primary control capacity as an electric power use from 3:00 to 6:00 (second time slot, which is the same as the first time slot). Therefore, from these displays on the display unit 13a, the user can easily understand that the reason for the standby from 3:00 to 6:00 is to prepare for contribution to the primary control capacity from 3:00 to 6:00.

[0050] For example, the operation plan image 41 and the charge status image 42 display that the storage battery is discharging from 6:00 to 9:00 (first time slot). Furthermore, the power selling price image 45 displays the power selling price from 6:00 to 9:00 (third time slot, the same as the first time slot). The power selling price from 6:00 to 9:00 (third time slot) is higher than the power selling prices in other time slots. Furthermore, in the illustrated example, the power selling price from 6:00 to 9:00 is higher than the base price displayed by the base price image 45a. Therefore, from these displays on the display unit 13a, the user can easily understand that the reason for this discharging is to sell power. For example, the operation plan image 41 and the charge status image 42 display that the storage battery is on standby from 3:00 to 6:00 (first time slot). In addition, the power selling price image 45 displays the power selling price from 6:00 to 9:00 (third time slot, different from the first time slot). The power selling price from 6:00 to 9:00 (third time slot) is higher than the power selling price in other time slots. Therefore, from these displays on the display unit 13a, the user can easily understand that the reason for this standby is to prepare for selling power. For example, the operation plan image 41 and the charging status image 42 display that the storage battery is charging from midnight to 3:00 (first time slot). In addition, the electricity selling price image 45 displays the electricity selling price from 6:00 to 9:00 (third time slot different from the first time slot). The electricity selling price from 6:00 to 9:00 (third time slot) is higher than the electricity selling price in the other time slots. Therefore, from these displays on the display unit 13a, the user can easily understand that the reason for this charging is to prepare for selling electricity.

[0051] For example, in the second example of the consideration screen shown in FIG. 5, the first display control means 153 causes the display unit 13a to display an operation plan image 41 and a charge state image 42 as a charge / discharge amount image 48. The first display control means 153 causes the display unit 13a to display an adjustment capacity image 43 (power use image 50) and a power purchase price image 46 as a reason image 49. The first example and the second example differ in that the power selling price image 45 is replaced with a power purchase price image 46. The power purchase price image 46 can be said to be an image showing the fourth time slot and the power purchase price corresponding to the fourth time slot. The first time slot and the fourth time slot may be the same time slot or different time slots.

[0052] According to the consideration screen of this second example, for example, the operation plan image 41 and the charging status image 42 display that the storage battery is charging from midnight to 3:00 (first time slot). Furthermore, the power purchase price image 46 displays the power purchase price from midnight to 3:00 (fourth time slot, the same as the first time slot). The power purchase price from midnight to 3:00 (fourth time slot) is lower than the power purchase price in other time slots. Therefore, from these displays on the display unit 13a, the user can easily understand that the reason for this charging is to purchase power during a time slot when the price is relatively low.

[0053] For example, in the consideration screen of the third example shown in FIG. 6, the first display control means 153 causes the display unit 13a to display an operation plan image 41 and a charge state image 42 as a charge / discharge amount image 48. The first display control means 153 causes the display unit 13a to display an adjustment capacity image 43 (power use image 50) and a power generation amount image 44 as a reason image 49. The first example and the third example differ in that the power selling price image 45 is replaced with the power generation amount image 44. The power generation amount image 44 can be said to be an image showing the fifth time slot and the power selling amount corresponding to the fifth time slot. The first time slot and the fifth time slot may be the same time slot or different time slots.

[0054] According to the consideration screen of the third example, for example, the operation plan image 41 and the charge state image 42 display that the storage battery is charging from midnight to 3:00 (first time slot). In addition, the power generation amount image 44 displays that power is being generated from midnight to 3:00 (fifth time slot, the same as the first time slot). Therefore, from these displays on the display unit 13a, the user can understand that the amount of charge is increasing as the amount of power generation increases.

[0055] Incidentally, in the consideration screen of the third example, it can be said that the first display control means 153 displays the power generation amount image 44 together with the operation plan image 41, the charge state image 42 (charge / discharge amount image 48), and the adjustment capacity image 43 (reason image 49). The adjustment capacity image 43 (reason image 49) also corresponds to the power generation amount image 44. According to the consideration screen of the third example, for example, the power generation amount image 44 displays that the power generation facility is generating 10 MWh of electricity from midnight to 3:00 (fifth time slot), and that the rechargeable battery is charging. Furthermore, the control capacity image 43 displays that the power usage will be contributed to the primary control capacity from 3:00 to 6:00 (second time slot different from the fifth time slot). Therefore, from these displays on the display unit 13a, the user can easily understand that the reason for power generation and charging from midnight to 3:00 is to prepare for contribution to the primary control capacity from 3:00 to 6:00.

[0056] For example, in the fourth example of the consideration screen shown in FIG. 7, the first display control means 153 causes the display unit 13a to display an operation plan image 41 and a charge state image 42 as a charge / discharge amount image 48. The first display control means 153 causes the display unit 13a to display an adjustment capacity image 43 (power use image 50) and a power demand image 47 as a reason image 49. The first example differs from the fourth example in that the power selling price image 45 is replaced with a power demand image 47. The power demand image 47 can be said to be an image showing the sixth time slot and the power demand corresponding to the sixth time slot. The first time slot and the sixth time slot may be the same time slot or different time slots.

[0057] According to the consideration screen of the fourth example, for example, the operation plan image 41 and the charge state image 42 display that the storage battery is discharging from 6:00 to 9:00 (first time slot). In addition, the power demand image 47 displays that there is a power demand from 6:00 to 9:00 (sixth time slot, which is the same as the first time slot). Therefore, from these displays on the display unit 13a, the user can easily understand that the reason for this discharge is to meet the power demand. For example, the operation plan image 41 and the charge status image 42 display that the storage battery is on standby from 3:00 to 6:00 (first time slot). In addition, the power demand image 47 displays that there is a demand for power from 6:00 to 9:00 (sixth time slot different from the first time slot). Therefore, from these displays on the display unit 13a, the user can easily understand that the reason for this standby is to prepare for a demand for power. For example, the operation plan image 41 and the charging status image 42 show that the storage battery is charging from midnight to 3:00 (first time slot). In addition, the power demand image 47 shows that there is a demand for power from 6:00 to 9:00 (sixth time slot different from the first time slot). Therefore, from these displays on the display unit 13a, the user can easily understand that the reason for this charging is to prepare for the power demand.

[0058] For example, in the consideration screen of the fifth example shown in Fig. 8, the first display control means 153 causes the display unit 13a to display an operation plan image 41 and a charge state image 42 as a charge / discharge amount image 48. The first display control means 153 causes the display unit 13a to display an adjustment capacity image 43 (power use image 50), a power generation amount image 44, and a power demand image 47 as a reason image 49. The first example and the fifth example differ in that the power selling price image 45 is replaced with a combination of the power generation amount image 44 and the power demand image 47. According to the consideration screen of the fifth example, the operation plan image 41, the charge state image 42, the power generation amount image 44, and the power demand image 47 are displayed on the display unit 13a, so that, for example, it is possible to easily understand both the reasons for charging and discharging the storage battery. Therefore, for example, it becomes easier to appropriately evaluate whether the operation plan of the storage battery is correct.

[0059] Here, the image generating means 152 may display, in addition to the above-mentioned images, an electricity sales amount image showing the amount of electricity sold, an electricity purchase amount image showing the amount of electricity purchased, etc. These electricity sales amount images and electricity purchase amount images function as reason images 49. In addition, the electricity sales amount image indicates electricity sales to the market, and also functions as an electricity use image 50. Furthermore, the image generating means 152 may display an image (hereinafter also referred to as a contract power image) showing the contract power (upper limit of power purchase amount) as the reason image 49. An example of the contract power image is a display such as "Power purchase amount 500 kW or less." The contract power image may be displayed together with the power purchase amount image, or may be displayed separately from the power purchase amount image. Generally, a penalty is incurred when purchasing power in excess of the contract power. For this reason, in order to refrain from purchasing power in excess of the contract power, a rechargeable battery may be discharged, and the contract power image can function as the reason image 49.

[0060] The first display control means 153 displays a storage battery identification image 52 and a display switching image 53, which are common to all of the review screens of the first to sixth examples shown in FIGS. 4 to 9 . The storage battery identification image 52 and the display switching image 53 are displayed in an area different from the area displaying the above-mentioned images (in the illustrated example, the area above). The storage battery identification image 52 displays information for identifying the storage battery being displayed. The display switching image 53 is an image that accepts switching between displaying the operation plan image 41 (charge / discharge amount image 48) in graph format or table format. When the user selects this display switching image 53 through the input unit 12, the first display control means 153 that accepts the selection switches, for example, the operation plan image 41 between graph format and table format. In this way, the first display control means 153 displays the charge / discharge amount image 48 in graph format or table format. Therefore, for example, the user can check the charge / discharge amount image 48 in a desired format.

[0061] FIG. 10 is a seventh example of the review screen displayed by the first display control means 153. 4 to 9 are based on planning information that does not assume the activation of adjustment capacity, as described above. As in the planning screen shown in Fig. 10, the first display control means 153 may display a planning screen that is based on planning information that assumes the activation of adjustment capacity.

[0062] FIG. 11 shows an example of a selection screen for the reason image 49. Here, the first display control means 153 can, for example, display each of the reason images 49 of the first to fifth examples shown in FIGS. 4 to 8 on the display unit 13a together with the operation plan image 41 and the charging state image 42. However, which image to display on the display unit 13a may be determined, for example, based on a user input. In this case, for example, the first display control means 153 may display a display image selection screen as shown in FIG. 11 on the display unit 13a. The selection screen displays selection images 54 corresponding to each of the above-mentioned reason images 49. The second display control means 154 may display the reason image 49 corresponding to the selected selection image 54 together with the operation plan image 41 and the charging state image 42. For example, multiple selection images 54 may be selected.

[0063] However, the method of selecting the display image is not limited to this. Furthermore, all of the reason images 49 may be displayed together with the operation plan image 41 and the charge state image 42 without selecting a display image. Here, displaying the reason image 49 together with the charge / discharge amount image 48 is not necessarily limited to the case where the reason image 49 and the charge / discharge amount image 48 are simultaneously displayed on the display unit 13a. For example, even if the reason image 49 and the charge / discharge amount image 48 are included on the same page but the entire page does not fit on the display unit 13a, the reason image 49 and the charge / discharge amount image 48 are not simultaneously displayed, and the reason image 49 and the operation plan image 41 are displayed by scrolling the screen, the reason image 49 may also be displayed together with the charge / discharge amount image 48.

[0064] FIG. 12 is an example of a portal screen displayed by the second display control means 154. As shown in FIG. The second display control means 154 causes the display unit 13a to display a first storage battery image 55 corresponding to the first storage battery and a second storage battery image 56 corresponding to the second storage battery. The second display control means 154 causes the display unit 13a to display both the first storage battery image 55 and the second storage battery image 56. When the user selects the first storage battery image 55 via the input unit 12, the first display control means 153 accepts the selection and displays an examination screen for the first storage battery image 55. When the user selects the second storage battery image 56 via the input unit 12, the first display control means 153 accepts the selection and displays an examination screen for the second storage battery image 56. In the illustrated example, the second display control means 154 causes the display unit 13a to display a display image setting image 57 together with the first storage battery image 55 and the second storage battery image 56. When the user selects the display image setting image 57 via the input unit 12, the first display control means 153 accepts the selection and displays a selection screen. However, the display image setting image 57 does not have to be present.

[0065] 2, the adjustment capacity bid success determination means 155 determines whether or not the bid for adjustment capacity was not successful. The adjustment capacity bid success determination means 155 may determine whether or not the bid for adjustment capacity was not successful by receiving an input from a user via the input unit 12, or may determine whether or not the bid for adjustment capacity was not successful by receiving a signal from an external device (for example, the planning device 20) via the network 70. The adjustment power activation determination means 156 determines whether or not an adjustment power has been activated. The adjustment power activation determination means 156 may determine whether or not an adjustment power has been activated by receiving an input from a user via the input unit 12, or may determine whether or not an adjustment power has been activated by receiving a signal from an external device (for example, the control device 30) via the network 70.

[0066] The plan correction determination means 157 determines whether the plan has been corrected. The plan correction determination means 157 may determine whether the plan has been corrected by receiving an input from a user via the input unit 12, or may determine whether the plan has been corrected by receiving a signal from an external device via the network 70. The plan correction determination means 157 may, for example, store the time when each storage battery image (first storage battery image 55 and second storage battery image 56) or the portal screen was last displayed, and determine that the plan has been corrected if the plan for each storage battery has been changed since that time. Note that the method for determining whether the plan has been corrected is not limited to this, and any method can be adopted.

[0067] The plan confirmation determination means 158 determines whether the plan has been confirmed. The plan confirmation determination means 158 may determine whether the plan has been confirmed by receiving an input from a user via the input unit 12, or by receiving a signal from an external device via the network 70. The plan confirmation determination means 158 may determine, for example, that the plan for a predetermined period has been confirmed when a predetermined time before the predetermined period has passed. Specifically, for example, the plan confirmation determination means 158 may determine that the plan has been confirmed when a plan for one day until the next day (e.g., January 2) has passed noon on the previous day (e.g., January 1). In this case, for example, the plan confirmation determination means 158 may determine that the plan for the next day has been confirmed if the current time is after noon (afternoon). Note that the method for determining whether the plan has been confirmed is not limited to this, and any method may be adopted. For example, when the planning device 20 transmits a plan (a signal corresponding to the plan) for a specific period to an external system, it may be determined that the plan for that period has been finalized. The external system may be, for example, a system that receives information about the plan from each electric utility. The system sends the received information about the plan to, for example, the Organization for Cross-regional Coordination of Transmission Operators (hereinafter also referred to as "OCCTO"). The Organization for Cross-regional Coordination of Transmission Operators is, for example, an organization that consolidates plans from each electric utility.

[0068] (Display control method) The following describes a display control method implemented by the display control device 10. The steps of the display control method differ depending on whether it is the planning stage or the plan execution stage. The display control device 10 may determine whether it is the planning stage or the plan execution stage by receiving input from a user via the input unit 12, or by receiving a signal from an external device via the network 70.

[0069] (Display control method in the planning stage) FIG. 13 is a flowchart showing a display control method implemented by the display control device 10 in the planning stage. A display control method in the planning stage, which is implemented by the display control device 10, will be described with reference to FIG.

[0070] First, the image source information acquisition means 151 acquires image source information (S10: information acquisition step). In the following, it is assumed that the plan information among the image source information acquired at this time is information that is based on the premise that a bid has been made in response to a public invitation for adjustment capacity. Next, the second display control means 154 causes the display unit 13a to display a portal screen such as that shown in FIG. 12 (S20: second display step). At this time, the second display control means 154 may change the display mode of one of the first storage battery image 55 and the second storage battery image 56 when either the charge / discharge amount of the first rechargeable battery or the charge / discharge amount of the second rechargeable battery is modified. The charge / discharge amount of the first rechargeable battery is the charge / discharge amount of the first storage battery planned by the EMS for a first future time slot. The charge / discharge amount of the second rechargeable battery is the charge / discharge amount of the second storage battery planned by the EMS for an eighth future time slot. This allows the user to easily identify the storage battery whose charge / discharge amount is to be modified. Whether either the charge / discharge amount of the first rechargeable battery or the charge / discharge amount of the second rechargeable battery has been modified can be determined, for example, by the plan modification determination means 157. In this embodiment, when one of the charge / discharge amounts of the first storage battery and the second storage battery is modified, the second display control means 154 changes the display mode of the first storage battery image 55 or the second storage battery image 56 corresponding to the modified amount. This allows the user to easily identify the storage battery whose charge / discharge amount is to be modified. As an example of changing the display mode, the second display control means 154 may change the background color of the first storage battery image 55 or the second storage battery image 56 or apply a blinking effect to the background color.

[0071] Next, the control unit 15 receives from the user a selection of a storage battery for which the user wishes to display a review screen (S30: selection receiving step). At this time, the control unit 15 may determine the selected storage battery, for example, based on an image selected on the portal screen. Furthermore, before this step, the first display control means 153 may display a selection screen for a reason image 49, for example, as shown in FIG. 11, and receive a selection of the reason image 49 to be displayed on the review screen.

[0072] Next, the first display control means 153 displays an examination screen, for example, as shown in Figures 4 to 10, on the display unit 13a (S40: first display control step). This step can also be said to display both the charge / discharge amount image 48 and the reason image 49 on the display unit 13a. In this embodiment, the first display control means 153 changes the display mode of at least a part of the review screen from the standard display mode depending on the conditions. This is expected to have the effect of, for example, alerting a user who views the display unit 13a. This will be specifically described below.

[0073] In the first display control step (S40), first, the control unit 15 determines whether or not there is adjustment capacity as a reason image 49 to be displayed on the consideration screen (S41). If it is determined that there is adjustment capacity (S41: Yes), the adjustment capacity success determination means 155 determines whether or not the bid for adjustment capacity was not successful (S42). If it is determined that the bid for adjustment capacity was not successful (S42: Yes), the first display control means 153 changes the display mode of at least one of the charge / discharge amount image 48 displayed on the display unit 13a and the reason image 49 displayed on the display unit 13a from the standard display mode (S43). Specific examples of changing the display mode include the first display control means 153 changing the color of the image, or the first display control means 153 superimposing a message image such as "The bid for adjustment capacity was not successful" on the charge / discharge amount image 48. By visually checking the consideration images with different display modes, for example, if the display mode of the charge / discharge amount image 48 is changed, the user can more easily understand that the charge / discharge plan for the storage battery should be revised. Alternatively, for example, if the display mode of the reason image 49 is changed, the user can more easily understand the reason for the revision of the charge / discharge plan (i.e., the adjustment capacity was not awarded).

[0074] When it is determined that there is no adjustable capacity (S41: No), when it is determined that there is no adjustable capacity and the bidder is not successful (S42: No), or when the display mode is changed after the successful bid determination (S43), the plan confirmation determination means 158 determines whether the plan is confirmed (S44). Here, the first display control means 153 changes the display mode of the charge / discharge amount image 48 depending on whether the charge / discharge amount is confirmed or not. In this embodiment, when it is determined that the plan is confirmed (S44: Yes), the display mode is changed from the standard charge / discharge amount image 48 (S45). A specific example of the change in the display mode is, for example, changing the color of the image by the first display control means 153. However, it is preferable that the change in the display mode in this step (S45) be different from the change in the display mode in step (S43) performed after the successful bid determination. In this embodiment, the first display control means 153 changes the display mode of the charge / discharge amount image 48 depending on whether the charge / discharge amount has been determined or not, thereby enabling the user to easily understand whether the charge / discharge amount has been determined or not.

[0075] If it is determined that the plan is not finalized (S44: No), or if the display mode is changed after the finalization determination (S45), the first display control means 153 displays the review image on the display unit 13a (S46). This completes the first display control step (S40).

[0076] Thereafter, the control unit 15 accepts the plan change (S50: plan change acceptance step). At this time, for example, the user may input the plan change to the display control device 10 by operating a table-formatted charge / discharge amount image 48 as shown in FIG. 9 via the input unit 12. For example, the control unit 15 may accept a change to the charge / discharge amount of each record in the table-formatted charge / discharge amount image 48 from the user, and the first display control means 153 may update the charge / discharge amount image 48 based on the accepted result. In this way, the table-formatted charge / discharge amount image 48 may be easier for the user to operate than the graph-formatted charge / discharge amount image 48. When the control unit 15 accepts the plan change, it may send information related to the change to the planning device 20 or the control device 30. This completes the display control method in the planning stage.

[0077] As described above, according to the display control device 10 of this embodiment, the first display control means 153 displays both the charge / discharge amount image 48 and the reason image 49 on the display unit 13a. This allows the user to easily understand the reason for the charge / discharge amount corresponding to the first future time slot. This makes it easier for the user to understand, for example, the validity of the EMS-based charge / discharge plan for the storage battery. Note that if the reason image 49 includes the power usage image 50, the user can understand the reason in more detail if the reason for the charge / discharge amount corresponding to the first time slot is related to the power usage.

[0078] (Display control method in execution stage) FIG. 14 is a flowchart showing a display control method performed by the display control device 10 in the plan execution stage. FIG. 15 is an eighth example of the review screen displayed by the first display control means 153. In FIG. FIG. 16 is a ninth example of the review screen displayed by the first display control means 153. A display control method in the plan execution stage, which is carried out by the display control device 10, will be described with reference to FIGS.

[0079] In this display control method, the acquisition of image source information (S10: information acquisition step), display of the portal screen (S20: second display control step), and acceptance of the selection of a storage battery (S30: selection acceptance step) are performed in the same manner. Note that, hereinafter, among the image source information acquired at this time, the plan information is assumed to be information that is based on the assumption that a bid for adjustment capacity has been won. Furthermore, it is assumed that the plan information is a plan that does not assume the activation of adjustment capacity. Thereafter, in the first display control step (S40), first, a review screen for the standard display mode is displayed (S46). Next, the adjustment power activation determination unit determines whether or not adjustment power has been activated (S47). If it is determined that adjustment power has been activated (S47: Yes), the first display control means 153 changes the display mode of at least one of the charge / discharge amount image 48 displayed on the display unit 13a and the reason image 49 displayed on the display unit 13a (S48a). As an example of changing the display mode, the first display control means 153 may superimpose a message image such as "Adjustment power has been activated" on the charge / discharge amount image 48, and may further highlight the reason image 49, for example. In addition, the first display control means 153 adds the charge / discharge amount after the plan change (the dashed graph line shown in FIG. 15) to the charge / discharge amount image 48 (S48b). In this way, the first display control means 153 displays the charge / discharge amount image 48 on the display unit 13a so that the charge / discharge amount before the adjustment capacity is activated and the charge / discharge amount after the adjustment capacity is activated can be compared. At this time, the display control device 10 may acquire plan information after the plan change (updated plan information) from, for example, the planning device 20 or the control device 30, and the image generation means 152 and the first display control means 153 may add the charge / discharge amount after the plan change to the charge / discharge amount image 48 based on the updated plan information. Specifically, at this time, for example, as shown in FIG. 15 , the background color of the reason image 49 may be changed and the charge / discharge amount after the plan change may be added to the charge / discharge amount image 48.

[0080] If it is determined that the adjustment power will not be activated in the second time slot (S47: No), the first display control means 153 changes the display mode of at least one of the charge / discharge amount image 48 displayed on the display unit 13a and the reason image 49 displayed on the display unit 13a (S49). The change in the display mode in this step (S49) is preferably different from the change in the display mode in step (S48a) performed after it is determined that the adjustment power has been activated. As an example of the change in the display mode, the first display control means 153 may superimpose a message image such as "Adjustment power has not been activated" on the charge / discharge amount image 48, and may further make the display of the reason image 49 less noticeable, for example.

[0081] The first display control step (S40) ends by adding the charge / discharge amount image 48 (S48b) or changing the display mode when it is determined that the adjustment power is not activated (S49). This completes the display control method.

[0082] In this method, the display mode is changed in both cases, when it is determined that the adjustment force has been activated, and when it is determined that the adjustment force will not be activated, but the display mode may be changed in only one of the cases. For example, as described above, when the plan information does not assume the activation of the adjustment capacity, if the adjustment capacity is not activated, there is no change in the plan. Therefore, when it is determined that the adjustment capacity will not be activated in the second time slot (S47: No), the first display control means 153 does not need to perform the step (S49) of changing the display mode of at least one of the charge / discharge amount image 48 displayed on the display unit 13a and the reason image 49 displayed on the display unit 13a. On the other hand, when the plan information assumes the activation of adjustment capacity, if adjustment capacity is not activated, there will be no change to the plan. Therefore, if it is determined that adjustment capacity has been activated (S47: Yes), the first display control means 153 does not need to perform the step (S48a) of changing the display mode of at least one of the charge / discharge amount image 48 displayed on the display unit 13a and the reason image 49 displayed on the display unit 13a. In this case, there is also no need to perform the step (S48b) of the first display control means 153 adding the charge / discharge amount after the plan change to the charge / discharge amount image 48. However, in this case, if adjustment capacity is not activated, there will be a change to the plan. Therefore, if it is determined that the adjustment power will not be activated in the second time zone (S47: No), the first display control means 153 may perform a step (S49) of changing the display mode of at least one of the charge / discharge amount image 48 displayed on the display unit 13a and the reason image 49 displayed on the display unit 13a, and then, as shown in Figure 16, the first display control means 153 may perform a step of adding the charge / discharge amount after the plan change (the dashed graph line shown in Figure 16) to the charge / discharge amount image 48.

[0083] Here, the plan is changed, for example, as follows. For example, if a change to the plan becomes necessary depending on whether or not adjustment power is activated, the user (e.g., an EMS operator) considers changing the plan using the planning device 20. After the changed plan is formulated, the user, for example, completes power trading in the hourly market at least one hour before the actual power sale, then sends information about the plan to an external system (a system that sends information to OCCTO) and submits a plan revision to OCCTO at least one hour before the actual supply and demand. The planning device 20 may send this changed plan information to the display control device 10.

[0084] As described above, according to the display control device 10 of this embodiment, when the adjustment capability is activated, the first display control means 153 changes the display mode of at least one of the charge / discharge amount image 48 and the reason image 49. Therefore, for example, when the adjustment capability is activated, the user can more easily understand that the charge / discharge plan of the storage battery will be modified, or the reason for the modification of the charge / discharge plan.

[0085] When the adjustment capacity is not activated, the first display control means 153 changes the display mode of at least one of the charge / discharge amount image 48 and the reason image 49. Therefore, for example, when the adjustment capacity is not activated, the user can more easily understand that the charge / discharge plan of the storage battery will not be corrected, or the reason why the charge / discharge plan will not be corrected.

[0086] The first display control means 153 displays the charge / discharge amount image 48 on the display unit 13a so that the charge / discharge amount before the regulation power is activated and the charge / discharge amount after the regulation power is activated can be compared. This allows the user to easily compare the charge / discharge amounts before and after the regulation power is activated.

[0087] (Hardware configuration of each device) FIG. 17 is a diagram illustrating an outline of an example hardware configuration of an information processing device 90 applied to this embodiment.

[0093] The embodiments of this disclosure have been described in detail above with reference to the drawings, but the specific configuration is not limited to this embodiment, and includes designs within the scope that do not deviate from the gist of this disclosure.

[0094] For example, in the above embodiment, the display control device 10, the planning device 20, and the control device 30 are configured as separate devices, but they may also be configured as an integrated device. For example, the functions of the planning device 20 and the control device 30 may be included in the display control device 10 as planning means and control means. At least one of the display control device 10, the planning device 20, and the control device 30 may be implemented using a plurality of information processing devices.

For example, the planning device 20 and the control device 30 may not be required. The present disclosure may simply display the review screen on the display unit 13a.

[0095] The first display control means 153 does not have to display the charge / discharge amount image 48 in a graph format or a table format. The first display control means 153 may display the charge / discharge amount image 48 only in a graph format, or may display the charge / discharge amount image 48 only in a table format.

[0096] The second display control means 154, the adjustment capacity bid determination means 155, the adjustment capacity activation determination means 156, the plan modification determination means 157, and the plan confirmation determination means 158 may not be present.

The first display control means 153 does not have to cause the display unit 13a to display the reason image 49 superimposed on the charge / discharge amount image 48. The reason image 49 does not have to include the power use image 50.

[0098] (Addendum) The embodiment can be understood, for example, as follows.

[0099] <1> A display control device according to one embodiment of the present invention is characterized by comprising a first display control means for causing a display unit to display a charge / discharge amount image showing a future first time period and the charge / discharge amount of a first storage battery planned by an EMS, which is the charge / discharge amount during the first time period, and a reason image corresponding to the reason for the charge / discharge amount corresponding to the charge / discharge amount image.

[0100] The first display control means causes the display unit to display both the charge / discharge amount image and the reason image. This allows the user to easily understand the reason for the charge / discharge amount corresponding to the first future time slot. This makes it easier for the user to understand, for example, the validity of the EMS's charge / discharge plan for the storage battery.

[0101] <2> the above <1> In the display control device according to the present invention, a configuration may be adopted in which the reason image includes a power usage image showing a future second time period and a power usage planned by the EMS that corresponds to the second time period.

[0102] The reason image includes a power usage image. Therefore, if the reason for the charge / discharge amount corresponding to the first time slot is related to the power usage, the user can understand the reason in more detail.

[0103] <3> the above <2> In the display control device according to the present invention, the power usage may include an adjustment power, and the first display control means may change the display mode of at least one of the charge / discharge amount image displayed on the display unit and the reason image displayed on the display unit when the adjustment power is activated.

[0104] When the adjustment capability is activated, the first display control means changes the display mode of at least one of the charge / discharge amount image and the reason image. Thus, for example, when the adjustment capability is activated, the user can more easily understand that the charge / discharge plan of the storage battery will be modified or the reason for the modification of the charge / discharge plan.

[0105] <4> the above <3> In the display control device according to the above, the first display control means may be configured to display the charge / discharge amount image on the display unit so that the charge / discharge amount before the adjustment force is activated and the charge / discharge amount after the adjustment force is activated can be compared.

[0106] The first display control means displays the charge / discharge amount image on the display unit so that the charge / discharge amount before the regulation power is activated and the charge / discharge amount after the regulation power is activated can be compared, thereby enabling the user to easily compare the charge / discharge amounts before and after the regulation power is activated.

[0109] <6> the above <2> ~ <5> In the display control device according to any one of the above aspects, the power usage may include adjustment capacity, and the first display control means may change the display mode of at least one of the charge / discharge amount image displayed on the display unit and the reason image displayed on the display unit when the adjustment capacity cannot be awarded.

[0110] When the bid for the adjustment capacity is not successful, the first display control means changes the display mode of at least one of the charge / discharge amount image and the reason image. Therefore, for example, when the bid for the adjustment capacity is not successful, the user can more easily understand that the charge / discharge plan of the storage battery will be revised or the reason for the revision of the charge / discharge plan.

[0111] <7> the above <2> ~ <6> In the display control device according to any one of the above aspects, a configuration may be employed in which the first time period and the second time period are different time periods.

[0112] The first time slot and the second time slot are different time slots. Therefore, even if the reason for the charge / discharge amount corresponding to the first time slot is the power usage corresponding to the second time slot, which is the time slot before or after the first time slot, the user can easily understand the reason.

[0113] <8> the above <1> ~ <7> In a display control device according to any one of the above embodiments, a configuration may be adopted in which the reason image includes a power selling price image showing a third time period and a power selling price corresponding to the third time period.

[0115] <9> the above <8> In the display control device according to the above, a configuration may be adopted in which the first time period and the third time period are the same time period.

[0116] The first time slot and the third time slot are the same time slot. Therefore, even if the reason for the charge / discharge amount corresponding to the first time slot is the electricity selling price corresponding to the third time slot, which is the same time slot as the first time slot, the user can easily understand the reason.

[0117] <10> the above <1> ~ <9> In a display control device according to any one of the above embodiments, a configuration may be adopted in which the reason image includes a power purchase price image showing a fourth time period and a power purchase price corresponding to the fourth time period.

[0119] <11> the above <1> ~ <10> In a display control device according to any one of the above embodiments, a configuration may be adopted in which the reason image includes a power generation amount image showing a fifth time period and the power generation amount corresponding to the fifth time period.

[0120] The reason image includes an image of the amount of power generation, so that if the reason for the charge / discharge amount corresponding to the first time slot is related to the amount of power generation, the user can understand the reason in more detail.

[0121] <12> the above <1> ~ <11> In any one of the above display control devices, a configuration may be adopted in which the reason image includes a power demand image showing a sixth time zone and the power demand corresponding to the sixth time zone.

[0122] The reason image includes an image of power demand, so that if the reason for the charge / discharge amount corresponding to the first time slot is related to power demand, the user can understand the reason in more detail.

[0123] <13> the above <1> ~ <12> In the display control device according to any one of the above embodiments, the first display control means may be configured to display, on the display unit, a power generation amount image showing a seventh time period and the amount of power generation in the seventh time period, together with the charge / discharge amount image and the reason image, and the reason image also corresponds to the power generation amount image.

[0124] The first display control means displays the power generation amount image on the display unit together with the charge / discharge amount image and the reason image, and the reason image also corresponds to the power generation amount image. Therefore, the user can easily understand the reason for the charge / discharge amount corresponding to the first time slot and the reason for the power generation amount corresponding to the seventh time slot by visually checking the same reason image. For example, the user can easily understand the validity of the power generation plan by the EMS.

[0125] <14> the above <1> ~ <13> In the display control device according to any one of the above aspects, the first display control means may be configured to cause the display unit to display the charge / discharge amount image and the reason image in association with each other.

[0127] <15> the above <1> ~ <14> In the display control device according to any one of the above aspects, the first display control means may be configured to superimpose the reason image on the charge / discharge amount image and display it on the display unit.

[0128] The first display control means causes the display unit to display the reason image superimposed on the charge / discharge amount image. This allows the user to view the charge / discharge amount image and the reason image superimposed on the charge / discharge amount image in a narrow field of view. This makes it easier for the user to understand the charge / discharge amount image and the reason image.

[0129] <16> the above <1> ~ <15> In the display control device according to any one of the above aspects, the first display control means may adopt a configuration that changes the display mode of the charge / discharge amount image depending on whether the charge / discharge amount is determined or not.
