[0005] However, in Patent Document 1, the price of the battery system was not assumed. Further, in Patent Document 2, it was not assumed to use an EMS that outputs power trading instruction information.

[0006] The present disclosure has been made in view of such problems, and an object thereof is to provide a technology that can easily enable a user to The cost of implementing a battery storage system controlled by an EMS, comprehend.

Means for Solving the Problems

[0007] A display control system according to one aspect of the present disclosure includes a display control means that causes a display unit to display in association first price information indicating the price of a first battery storage system and first revenue information indicating the revenue obtained by controlling the first battery storage system by an EMS, wherein the EMS outputs transaction instruction information indicating an instruction to trade electricity. [Effects of the Invention]

[0008] In this disclosure, the user will be informed that The cost of implementing a battery storage system controlled by an EMS, We can provide technology that makes it easy to understand. [Brief explanation of the drawing]

[0009] [Figure 1] This is a block diagram showing the configuration of the output device in this embodiment. [Figure 2] This is a block diagram showing the configuration of the control unit of this embodiment. [Figure 3] This embodiment shows an example of a screen displayed on the display unit. [Modes for carrying out the invention]

[0010] Traditionally, power generation companies, acting on instructions from the general transmission and distribution companies that deliver electricity generated at power plants to consumers, were sometimes required to reduce their power output (electricity supply) during periods when demand for electricity decreased and supply became excessive (such as in spring and autumn). There was no compensation for such output reductions, and when output was reduced, power generation companies were essentially wasting electricity and therefore unable to obtain the profits they would have earned from selling it.

[0011] To address these issues, power generators can install battery storage systems, for example, to store surplus electricity generated during power output curtailment. Furthermore, they can generate revenue by efficiently trading this stored electricity through an Energy Management System (EMS).

[0012] An Energy Management System (EMS) is a system designed to monitor energy use and improve the efficiency of power operations. For example, if the target of the EMS is a battery storage system or a power plant, the EMS can be applied to the efficient operation of batteries (demand during charging, supply during discharging) (for example, optimal operation of charging and discharging for each time period). For example, if the target of the EMS is a power source and consumer in a specific region, it can be applied to the efficient operation of the amount of electricity demanded and supplied in that region (for example, optimal operation). By introducing an EMS, for example, the efficiency of each of the operations mentioned above (for example, optimization) can be improved. As a result, it may be possible to reduce costs or increase profits compared to not introducing an EMS.

[0013] On the other hand, the introduction of energy storage systems and EMS (Energy Management Systems) incurs costs.

[0014] The technology disclosed herein can be used, for example, to understand the costs involved in implementing a battery storage system and an EMS, and to obtain information regarding the operation of the battery storage system and the EMS. The user may be, for example, a business that sells, leases, or provides battery storage systems or EMS, or a business (e.g., a power generation company) that is considering implementing a battery storage system or an EMS.

[0015] Hereinafter, a display control system 1, a display control method, and a display control program according to one embodiment of this disclosure will be described with reference to the drawings.

[0016] (Display control system) Figure 1 is a block diagram showing a specific example of the configuration of the display control system 1 of this embodiment. The display control system 1 comprises a communication unit 10, an input unit 20, a display unit 30, a storage unit 40, and a control unit 50.

[0017] The communication unit 10 is a communication device. The communication unit 10 may be configured as, for example, a network interface. The communication unit 10 performs data communication with other devices via a network according to the control of the control unit 50. The communication unit 10 may be a device that performs wireless communication or a device that performs wired communication.

[0018] The input unit 20 is configured using existing input devices such as a keyboard, a pointing device (mouse, tablet, etc.), buttons, a touch panel, etc. The input unit 20 is operated by the user when inputting the user's instructions into the display control system 1. The input unit 20 may be an interface for connecting the input device to the display control system 1. In this case, the input unit 20 inputs an input signal generated according to the user's input in the input device into the display control system 1. The input unit 20 may be configured using a microphone and a voice recognition device. In this case, the input unit 20 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 into the display control system 1. The voice recognition processing may be executed by the control unit 50. The input unit 20 may be configured in any manner as long as it can input the user's instructions into the display control system 1.

[0019] The display unit 30 displays information, for example, in a form recognizable by the user. The display unit 30 may be an image display device such as a liquid crystal display, an organic EL (Electro Luminescence) display, etc. Note that the display unit 30 may be configured as a touch panel integrated with the input unit 20.

[0020] The storage unit 40 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 40 stores data used by the control unit 50. The storage unit 40 stores data required when the control unit 50 performs processing.

[0021] The control unit 50 is composed of a processor P such as a CPU (Central Processing Unit) and a memory M (main storage device). As shown in FIG. 2, the control unit 50 functions as a calculation means 51 and a display control means 52 when the processor P executes a program (display control program). 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 storage device (e.g., SSD: Solid State Drive), or a storage device such as a hard disk or a semiconductor storage device built into a computer system. The above program may be transmitted via a telecommunication line.

[0022] The calculation means 51 calculates, for example, the following-described information based on various information of the battery.

[0023] The display control means 52 causes the display unit 30 to display various information of the battery stored in the storage unit 40 and the calculation result calculated by the calculation means 51, for example, as a table image 100. The display control means 52 may function as a change means 52a and change a part or all of the table image 100 displayed on the display unit 30 based on various information of the battery stored in the storage unit 40 and the calculation result calculated by the calculation means 51.

[0024] The display control system 1 of the present embodiment includes display control means 52 that causes the display unit 30 to display, in association with each other, first price information 111 indicating the price of the first battery system and first revenue information 211 indicating the revenue obtained by controlling the first battery system by the EMS. The EMS outputs transaction instruction information indicating a power transaction instruction. Note that the EMS may be on a system different from the display control system 1 or may be on the display control system 1.

[0025] While referring to FIG. 3, an example of information displayed by the display control means 52 in the display control system 1 of the present embodiment on the display unit 30 will be described. Note that the strings and numbers shown in Figure 3 are merely hypothetical examples used for illustrative purposes and do not necessarily correspond to actual strings or numbers.

[0026] Figure 3 is an example of an image displayed on the display unit 30 by the display control means 52. The image may change, for example, by the modification means 52a changing the information. The image may also change, for example, by updating the information through user input. The information shown in Figure 3, or information for calculating the information shown in Figure 3, may be stored in the storage unit 40. In this case, the display control means 52 may read this information from the storage unit 40 and display it on the display unit 30. The calculation means 51 may also calculate other information to be displayed on the display unit 30 based on the information read from the storage unit 40.

[0027] In the following explanation, we will describe a case where multiple candidates are displayed on the display unit 30 in a comparable manner. Each candidate employs a different battery system. Specifically, we will describe a case where candidate 1, which uses the first battery system, is compared with candidate 2, which uses the second battery system. However, the display unit 30 may display one candidate or three or more. Furthermore, the specific display format of the various information is not limited to the images shown.

[0028] The first battery system and the second battery system may differ in at least one of the following: capacity, manufacturer, type, and remaining lifespan. The first battery system and the second battery system may be subject to different controls. Specifically, the first battery system and the second battery system may differ in at least one of the following: charge / discharge amount, charge / discharge time, and time of day (timing) in which charge / discharge occurs. The first battery system and the second battery system may differ in at least one of the following: power source for charging, power application to which discharge occurs (details below), charge / discharge amount, charge / discharge time, and time of day (timing) in which charge / discharge occurs.

[0029] Here, displaying information in a corresponding manner means that the information is displayed in a form that allows the user to recognize the correspondence between the pieces of information. Displaying information in a corresponding manner may mean, for example, displaying the information in the same column or the same row in the table image 100 displayed on the display unit 30, as shown in the illustrated example. This information may be based on information received by the communication unit 10, or on information stored in the storage unit 40, or on information calculated by the calculation means 51 based on the information stored in the storage unit 40. The display control means 52 displays this various information on the display unit 30 as described above.

[0030] According to the display control system 1 (display control means 52) of this embodiment, as shown in Figure 3, price information 110, revenue information 210, location information 130, power generation type information 140, power generation amount information 150, transaction power generation amount information 160, function information 180, EMS price information 190, facility type information 170, and remaining lifespan information 120 are associated with each other and displayed on the display unit 30.

[0031] In the display control system 1 of this embodiment, the display control means 52 only needs to display at least the first price information 111 indicating the price of the first battery system and the first revenue information 211 indicating the revenue obtained by controlling the first battery system by the EMS on the display unit 30, and is not limited to displaying all of the above information on the display unit 30. The information displayed by the display control means 52 may be only a part of the above information.

[0032] Price information 110 is information indicating the price of the battery storage system. In this embodiment, first price information 111, which indicates the price of the first battery storage system, and second price information 112, which indicates the price of the second battery storage system, are displayed on the display unit 30. In this embodiment, the capacity of the second battery storage system is greater than the capacity of the first battery storage system, and the price of the second battery storage system is higher than the price of the first battery storage system. The capacity and price of the first and second battery storage systems may be the same. The price information 110 may be stored in the memory unit 40, or it may be calculated by the calculation means 51 based on information regarding the price of the battery system.

[0033] Because the amount of electricity that can be traded varies depending on the storage capacity of the battery system, revenue information 210 may change. Capacity information indicating the capacity of the battery storage system may be used instead of price information 110. Capacity information may be stored in the storage unit 40, or it may be entered by the user.

[0034] Revenue information 210 is information that shows the revenue obtained by controlling the battery storage system by the EMS. More specifically, for example, it may show the revenue obtained by charging the battery storage system with electricity generated during a period when the power generation system suppresses the supply of power (output suppression period), and then selling the charged electricity after the output suppression period. In this embodiment, the revenue shown as revenue information 210 is a predicted value.

[0035] In this embodiment, first revenue information 211, which is information indicating the revenue obtained by controlling the first battery storage system by the EMS, and second revenue information 212, which is information indicating the revenue obtained by controlling the second battery storage system by the EMS, are displayed. The revenue information 210 may be, for example, an amount calculated by the calculation means 51 based on past operational results, based on the amount of power generated and traded under the control of the EMS, and information indicating the function of the EMS that controls the battery storage system described later (function information 180).

[0036] Even when operating the same battery storage system, the revenue obtained may differ depending on the functions of the EMS (Energy Management System) that control the battery storage system. For example, the revenue obtained for each function of the EMS that controls the battery storage system may be displayed on the display unit 30.

[0037] The function information 180 is information indicating the function of the EMS that controls the battery storage system. The function information 180 may also be information indicating the power use, which is the use of the power used by the charging and discharging of the battery storage system. The types of functions of an EMS are not limited, but examples include: (1) trading in the supply and demand adjustment market, (2) buying and selling in the advance market, (3) trading in multiple markets (for example, trading as primary or secondary adjustment power), (4) using it for imbalance control, (5) buying and selling in the wholesale (spot) market, (6) earning revenue through FIP (Feed In Premium), (7) earning revenue through environmental value, (8) using it for peak shifting, (9) using it for over-the-counter trading, and (10) using it for self-consignment. The functions of the EMS in this embodiment are for power applications, and the type is one of the above applications (1) to (10).

[0038] The display control means 52 of this embodiment displays the first function information 181 indicating the first function of the EMS, the second function information 182 indicating the second function of the EMS, the first price information 111, and the first revenue information 211 on the display unit 30 in association with each other. In addition, the first revenue information 211 in this embodiment includes the first-first revenue information 211a and the first-second revenue information 211b, and the display control means 52 displays the first function information 181 and the first-first revenue information 211a on the display unit 30 in association with each other, and also displays the second function information 182 and the first-second revenue information 211b on the display unit 30 in association with each other. In this embodiment, the second revenue information 212 includes the second-first revenue information 212a and the second-second revenue information 212b, and the display control means 52 displays the first function information 181 and the second-first revenue information 212a in association with each other on the display unit 30, and also displays the second function information 182 and the second-second revenue information 212b in association with each other on the display unit 30.

[0039] In the example in Figure 3, the column for Candidate 1 is partially divided into two columns depending on whether the first battery system is controlled by the first function of the EMS or by the second function of the EMS. In such cases, for example, in order to display the first function information 181 and the second function information 182 in association with the first price information 111 on the display unit 30, it is also possible to divide the column displaying the first price information 111 into multiple columns in the cells where the first function information 181 and the second function information 182 are displayed, and then display the first function information 181 and the second function information 182 in these divided cells.

[0040] In this embodiment, as shown in Figure 3, the first function information 181a, which indicates the first function of the EMS controlling the first battery system, and the second function information 181b, which indicates the first function of the EMS controlling the second battery system, display "peak shift" indicating that it will be used for the peak shift function. The first function information 182a, which indicates the second function of the EMS controlling the first battery system, and the second function information 182b, which indicates the second function of the EMS controlling the second battery system, display "supply and demand adjustment" indicating that it will be traded in the supply and demand adjustment market.

[0041] In this embodiment, "￥〇〇〇" is displayed as the first-1 revenue information 211a, which shows the revenue when the first battery storage system is operated using the first function (peak shift) of the EMS; "￥〇〇〇" is displayed as the first-2 revenue information 211b, which shows the revenue when the first battery storage system is operated using the second function (supply and demand adjustment) of the EMS; "￥△△△" is displayed as the second-1 revenue information 212a, which shows the revenue when the second battery storage system is operated using the first function of the EMS; and "￥△△△" is displayed as the second-2 revenue information 212b, which shows the revenue when the second battery storage system is operated using the second function of the EMS.

[0042] In the example shown in Figure 3, for convenience, the first revenue information 211a and the first revenue information 211b are both displayed as "￥〇〇〇", and the second revenue information 212a and the second revenue information 212b are both displayed as "￥△△△". However, in reality, each of these pieces of information may be completely different, partially different, or all identical.

[0043] In this embodiment, the first function of the EMS in both the first battery system and the second battery system is peak shifting, and the second function is supply and demand adjustment; however, the first and second functions of the EMS in the first battery system and the second battery system do not have to be the same.

[0044] Next, we will explain the power applications (1) to (10).

[0045] The supply and demand adjustment market described in (1) above is a market for adjustment capacity. The supply and demand adjustment market is a market for procuring the adjustment capacity necessary to balance the supply and demand of electricity. The supply and demand adjustment market publicly offers for adjustment capacity. Those who own power sources (for example, batteries or power generation equipment) have the right to supply electricity as adjustment capacity if they win a bid in the public offering of the supply and demand adjustment market. If a power source owner wins a bid for a buffering capacity, they will supply electricity as buffering capacity when the buffering capacity is activated. However, even if a power source owner wins a bid for a buffering capacity, they will not supply electricity as buffering capacity if the buffering capacity is not activated. When a power source owner wins a bid for a buffering capacity, they receive income in proportion to the amount of electricity supplied for that buffering capacity. Furthermore, when a buffering capacity is activated and electricity is supplied as buffering capacity, the power source owner can earn profits from selling electricity to the buffering capacity market (income in proportion to the amount of electricity supplied).

[0046] The pre-hours market mentioned in (2) above is, for example, a market where trading is possible up to one hour before actual supply and demand. The Organization for Cross-regional Coordination of Transmission Operators (hereinafter also referred to as "OCCTO") is an organization that aggregates plans from each electric utility. OCCTO receives sales plans, and in return, it submits generation plans and corresponding sales plans, as well as demand plans and corresponding procurement plans. However, at the actual supply and demand level, discrepancies may arise between the sales plans sent to OCCTO and the actual amount of power generated and demanded, resulting in differences between actual sales and procurement and the sales and procurement plans. Such discrepancies (imbalances) can arise, for example, from failures in power generation equipment. Specifically, the following types of imbalances occur at the actual supply and demand level: • When power generation decreases, actual sales decrease. The difference between the actual decrease in sales and the sales plan becomes an imbalance. • When power generation increases, actual sales increase. The difference between the actual increase in sales and the sales plan becomes a surplus imbalance. When demand increases, the actual amount procured increases. The difference between the increased actual amount procured and the procurement plan becomes a shortage or imbalance. When demand decreases, the actual amount procured decreases. The difference between the actual amount procured and the procurement plan becomes an imbalance. In the event of any surplus or deficit imbalance as described above, the customer (electricity provider) will bear the final adjustment costs, for example, the marginal costs incurred by the former general electric utility, as imbalance unit prices and imbalance expenses. The deficit and surplus imbalance charges will be determined, for example, by methods determined by the Electricity and Gas Market Surveillance Commission. Customers (electricity providers) need to strive to minimize such imbalances. Therefore, if an imbalance is anticipated and trading is possible in the aforementioned pre-market, they will attempt to resolve the imbalance by, for example, trading in the pre-market.

[0047] The above (3) Buying and selling electricity in multiple markets may include, for example, buying and selling electricity in different markets such as the spot market and the supply and demand adjustment market. Furthermore, buying and selling electricity in multiple markets may also include, for example, buying and selling electricity as primary and secondary adjustment power in the supply and demand adjustment market (buying and selling as different commodities in the same market).

[0048] The imbalance control described in (4) above involves, for example, adjusting the timing of imbalance generation. Specifically, for instance, while predicting the imbalance price, when the imbalance price is high (supply and demand are tight), a shortage is not generated, and a surplus is created to supply power to the grid. On the other hand, when the imbalance price is low (there is a surplus of electricity in the grid), a shortage is created to take in the surplus electricity from the grid, and no surplus is generated.

[0049] Regarding (5) to (7) above, for example, with regard to the buying and selling of electricity, the EMS, for example, formulates the buying and selling plan for the following day by 12:00 the day before and sends it to OCCTO. When electricity is bought and sold in accordance with this plan, it is bought and sold in the spot market as described in (5) above. When electricity is sold to the market, if that electricity is generated based on renewable energy, the FIP premium described in (6) above is added to the normal electricity price. The FIP premium is the value added to electricity generated from renewable energy. This added value may be, for example, a subsidy from a public institution such as the national or local government. Incidentally, if the electricity is from renewable energy sources, the generated electricity will have environmental value as described in (7) above. This environmental value can be bought and sold, for example, in an environmental value trading market different from the electricity market (for example, a non-fossil fuel value trading market).

[0050] The peak shift function described in (8) above is a function related to the formulation of a plan. The peak shift function is a function that equalizes the supply and demand of electricity. When the peak shift function equalizes the demand for electricity, for example, electricity demand during peak demand hours (e.g., daytime electricity consumption) is reallocated to electricity demand during off-peak hours (e.g., nighttime electricity consumption). Reallocation of electricity demand is achieved, for example, by changing the time of day when batteries are charged. When the peak shift function equalizes the supply for electricity, for example, electricity supply during peak supply hours is reallocated to electricity supply during off-peak hours. Reallocation of electricity supply is achieved, for example, by changing the time of day when power generation equipment generates electricity, or by changing the time of day when batteries are discharged.

[0051] The over-the-counter transactions described in (9) above refer to a form of transaction in which power generators and retailers trade directly with each other without going through a wholesale market.

[0052] The self-consignment described in (10) above refers to the transmission of electricity generated from power generation facilities owned by the company in remote locations to the company's own facilities that use the electricity, for use by the company itself.

[0053] The function information 180 to be displayed may be determined by the user, for example, or by the user selecting from a list of EMS function candidates proposed by AI or the like. The function information 180 to be displayed may be changed by the user. If the function information 180 is changed by the user, the information displayed on the display unit 30 may be changed by the changing means 52a. If the function information 180 is changed by the user, the revenue information 210 and the EMS price information 190 displayed on the display unit 30 may be updated and changed by the changing means 52a.

[0054] Depending on the type of power generation system owned by the user implementing the EMS, the order in which output curtailment is applied and the amount of power generated may differ. Therefore, the type of power generation system owned by the user implementing the EMS may affect price information 110 and revenue information 210.

[0055] The power generation type information 140 is information indicating the type of power generation system owned by the user who is installing the EMS. For example, the power generation type information 140 should be information that allows the user to recognize the type of power generation system owned by the user who is installing the EMS. The type of power generation system owned by a user who implements an EMS is not limited. Examples of power generation systems owned by users who implement an EMS include solar power, wind power, thermal power, and cogeneration systems.

[0056] In this embodiment, as shown in Figure 3, "Solar power generation" is displayed as the type information, which is the type of power generation system owned by the user who is introducing the EMS.

[0057] The power generation type information 140 may be stored in the memory unit 40, or it may be entered by the user.

[0058] The power generation information 150 is information indicating the power generation amount of the power generation system owned by the user who is installing the EMS. The power generation information 150 only needs to be information that allows the user to recognize the power generation amount of the power generation system owned by the user who is installing the EMS.

[0059] In this embodiment, as shown in Figure 3, the power generation amount information 150, which indicates the amount of power generated by the power generation system owned by the user who is introducing the EMS, is displayed as "〇kWh". The amount of power generated shown in the power generation amount information 150 may be the past operating performance of the power generation system or it may be a predicted value. The power generation amount information 150 may be stored in the storage unit 40, for example, or it may be entered by the user. The power generation amount information 150 may be calculated by the calculation means 51 based on, for example, the power generation type information 140, the location information 130 described later, etc.

[0060] Even when operating the same power generation system, the amount of power generated or the frequency of output curtailment may differ depending on the location of the power generation system.

[0061] Location information 130 is information indicating the location of the power generation system. Location information 130 only needs to be information that allows the user to recognize the location of the power generation system.

[0062] In this embodiment, as shown in Figure 3, the location information 130 indicating the location of the power generation system is displayed as "〇 Prefecture 〇 City". The location information 130 may be, for example, an address, or for example, a power area. The power area displayed as location information 130 may be any of the following: Hokkaido Electric Power area, Tohoku Electric Power area, Hokuriku Electric Power area, Chubu Electric Power area, Tokyo Electric Power area, Kansai Electric Power area, Chugoku Electric Power area, Shikoku Electric Power area, Kyushu Electric Power area, or Okinawa Electric Power area.

[0063] If not all of the power generation amount shown in power generation information 150 is used for trading by the EMS, the amount of power generated by the power generation system as electricity and the amount of power generated for trading that is the subject of the trading instruction information output by the EMS may differ.

[0064] The transactional power generation information 160 is information that indicates the transactional power generation amount, which is the amount of power generation that is subject to the transaction instruction information output by the EMS, out of the total power generation. The transactional power generation information 160 only needs to be information that the user can recognize as the transactional power generation amount, which is the amount of power generation that is subject to the transaction instruction information output by the EMS, out of the total power generation.

[0065] In this embodiment, as shown in Figure 3, when the first battery storage system is used, "〇kWh" is displayed as the first transactional power generation information, which indicates the amount of power generated that is the subject of the transaction instruction information output by the EMS. When the second battery storage system is used, "△kWh" is displayed as the second transactional power generation information, which indicates the amount of power generated that is the subject of the transaction instruction information output by the EMS.

[0066] The amount of electricity traded changes depending on the amount of electricity that can be stored in the battery storage system, for example, depending on the size of the battery storage system. For example, the amount of electricity traded may be calculated by the calculation means 51 for each battery storage system based on the amount of electricity that can be stored in the battery storage system.

[0067] EMS price information 190 shows the price of EMS (Electronic Mail Service). EMS prices vary depending on, for example, their features.

[0068] In this embodiment, as shown in Figure 3, the first-1 EMS price information 191a, which is the price of an EMS having a first function (peak shift function) for controlling the first battery system, is displayed as "￥〇〇〇", the first-2 EMS price information 191b, which is the price of an EMS having a second function (supply and demand adjustment function) for controlling the first battery system, is displayed as "￥〇〇〇", the second-1 EMS price information 192a, which is the price of an EMS having a first function (peak shift function) for controlling the second battery system, is displayed as "￥△△△", and the second-2 EMS price information 192b, which is the price of an EMS having a second function (supply and demand adjustment function) for controlling the second battery system, is displayed as "￥△△△".

[0069] In the example shown in Figure 3, for convenience, the 1st-1 EMS price information 191a and the 1st-2 EMS price information 191b are both displayed as "￥〇〇〇", and the 2nd-1 EMS price information 192a and the 2nd-2 EMS price information 192b are both displayed as "￥△△△". However, in reality, each of these pieces of information may be completely different, partially different, or all the same.

[0070] The EMS price information 190 may be stored in the storage unit 40 or entered by the user. The EMS price information 190 may be calculated by the calculation means 51 based on information regarding the scale of the battery storage system controlled by the EMS and information regarding the required functions of the EMS (function information 180).

[0071] Facility type information 170 is information indicating the type of facility owned by the user installing the battery storage system. Facility type information 170 only needs to be information that the user can recognize, indicating the type of facility owned by the user installing the battery storage system.

[0072] In this embodiment, as shown in Figure 3, "Plant" is displayed as facility type information 170. The type of facility displayed as facility type information 170 is not limited, but it is preferably a large-scale facility with multiple tenants, and may be, for example, a plant, a logistics warehouse, a shopping mall, or a residential building (such as a high-rise apartment building). The plant is not limited, but may be, for example, a chemical plant, a steel plant, a food processing plant, a sludge solid fuel plant, an on-site energy plant (cogeneration plant), a biomass power plant, a geothermal power plant, a carbon dioxide capture plant, a bioethanol plant, or a data center.

[0073] The facility type information 170 may be stored in the memory unit 40, or it may be entered by the user.

[0074] The remaining lifespan information 120 is information indicating the remaining lifespan of the battery system. The remaining lifespan information 120 should be information that the user can recognize regarding the remaining lifespan of the battery system. The remaining lifespan information 120 may be, for example, the number of times the battery system can be charged and discharged (remaining cycle count), for example, the degree of degradation, or for example, the monetary value (market value) of the battery system. The degree of degradation indicates the current performance level of the battery system, for example, when the performance of a new (undegraded) battery system is set to 100%. Specifically, for example, if the degree of degradation of a battery system is 60%, it indicates that the battery system has 60% of the performance of a new system.

[0075] In this embodiment, as shown in Figure 3, the remaining life information is indicated by the number of remaining cycles. In this embodiment, the first remaining life information indicating the expected life of the first battery system is displayed as "〇 cycles", and the second remaining life information indicating the expected life of the second battery system is displayed as "△ cycles".

[0076] The first remaining life information and the second remaining life information may be different or the same.

[0077] Users can easily understand the costs involved in installing a battery storage system or EMS, and how much profit they can expect to gain from trading electricity through the EMS, given those costs. Specifically, for example, when a company selling battery storage systems or EMS proposes the installation of such a system to a power generation company that owns a power generation system, the power generation company can easily understand the costs involved in installing the system and the resulting profits.

[0078] (Display control method) The display control method of this embodiment comprises a display control step and a modification step. However, the display control method only needs to include the display control step; the modification step is not required.

[0079] In the display control step of this embodiment, price information 110, revenue information 210, location information 130, power generation type information 140, power generation amount information 150, transaction power generation amount information 160, function information 180, EMS price information 190, facility type information 170, and remaining lifespan information 120 are displayed in association with each other on the display unit 30.

[0080] In the display control step, it is sufficient that at least the first price information 111 indicating the price of the first battery system and the first revenue information 211 indicating the revenue obtained by controlling the first battery system by the EMS are associated and displayed on the display unit 30, and it is not limited that all of the above information is displayed on the display unit 30. The information displayed on the display unit 30 in the display control step may be only a part of the above information, or it may include information other than the above information.

[0081] In the display control step of this embodiment, the table image 100 shown in Figure 3 is output. Detailed explanations of each of the above pieces of information can be the same as those provided in the display control system 1, so they are omitted here.

[0082] In the change step, the information displayed on the display unit 30 is changed. In the change step, for example, the information displayed on the display unit 30 is changed based on the information changed according to the user's input.

[0083] Furthermore, if the information displayed on the display unit 30 is changed during the change step, the user may be notified of the changed information. The notification may be, for example, by displaying the information in a pop-up manner on the display unit 30, or by highlighting the information displayed on the display unit 30. The specific form of the highlighting is not limited, but for example, the color of the information may be changed, or the information may be displayed in bold.

[0084] As described above, the display control system 1 of this disclosure includes a display control means 52 that displays in association with first price information 111 indicating the price of the first battery storage system and first revenue information 211 indicating the revenue obtained by controlling the first battery storage system by the EMS on the display unit 30, and the EMS outputs transaction instruction information indicating a power transaction instruction. With this configuration, the user can understand the price of the first battery storage system by checking the first price information 111, and understand the revenue obtained by controlling the first battery storage system by the EMS by checking the corresponding first revenue information 211. As a result, the user can check, for example, the cost of investing in the battery storage system or EMS, and how much revenue can be obtained from the operation of the battery storage system and EMS, by looking at the display unit 30. Thus, the user can easily understand the cost of introducing the battery storage system and EMS, and information regarding the operation of the battery storage system and EMS. Based on this information, the user can decide whether or not to introduce the battery storage system or EMS.

[0085] Furthermore, the display control means 52 may display on the display unit 30 the power generation type information 140, which indicates the type of power generation system owned by the user introducing the EMS, along with the first price information 111 and the first revenue information 211. The price of the battery storage system and the revenue generated by installing the battery storage system may vary depending on the type of power generation system owned by the user. With the above configuration, by checking the power generation type information 140, the user installing the EMS can understand the type of power generation system owned by the user, and can also reliably understand the first price information 111 and first revenue information 211 corresponding to the power generation type information 140.

[0086] Furthermore, the first revenue information 211 may also be revenue generated by charging the first battery storage system with electricity generated by the power generation system during the output curtailment period, and then selling the charged electricity after the output curtailment period. Traditionally, periods of output curtailment have been implemented during times of excessive power supply. With this configuration, users can charge the battery system with the electricity generated during the power curtailment period and then track the profits they can earn by trading the charged electricity through an Energy Management System (EMS) after the curtailment period.

[0087] Furthermore, the display control means 52 may display location information 130 indicating the location of the power generation system owned by the user introducing the EMS, along with the first price information 111 and the first revenue information 211, on the display unit 30 in association with each other. Even when operating the same power generation system, the amount of power generated or the frequency of output curtailment may differ depending on the location of the power generation system. With the above configuration, by checking the location information 130, the user can understand the location of the power generation system owned by the user introducing the EMS, and can also reliably understand the first price information 111 and first revenue information 211 corresponding to the location information 130.

[0088] Furthermore, the display control means 52 may display on the display unit 30 the power generation amount information 150, which indicates the amount of power generated by the power generation system owned by the user introducing the EMS, in association with the first price information 111 and the first revenue information 211. With this configuration, users can understand the amount of power generated by their own power generation system by checking the power generation amount information 150, and can also reliably understand the first price information 111 and first revenue information 211 corresponding to the power generation amount information 150. As a result, users can understand, for example, that when the amount of power generated is large, the required battery storage system will be larger and the first price information 111 will be more expensive, and that when the amount of power stored in the battery storage system is large, the first revenue information 211 will also be more expensive.

[0089] Furthermore, the display control means 52 may display on the display unit 30 a transaction power generation amount information 160, which indicates the transaction power generation amount that is the amount of power generation that is the subject of the transaction instruction information output by the EMS, in association with the first price information 111 and the first revenue information 211. With this configuration, the user can understand the amount of electricity that is subject to the trading instruction information output by the EMS by checking the trading amount information 160, and can also understand the first price information 111 and first revenue information 211 that correspond to the trading amount information 160. As a result, the user can understand that, for example, when the amount of electricity generated is large, the amount of electricity traded by the EMS will be large, and therefore the first price information 111 and first revenue information 211 will be high.

[0090] Furthermore, the display control means 52 may display the first function information 181 indicating the first function of the EMS, the second function information 182 indicating the second function of the EMS, the first price information 111, and the first revenue information 211 in association with each other on the display unit 30. With this configuration, users can reliably grasp the first function information 181 and the second function information 182, and the corresponding first price information 111 and first revenue information 211. This makes it easy to understand the differences in implementation costs and revenues resulting from differences in EMS functions.

[0091] Furthermore, the first revenue information 211 includes the first-1 revenue information 211a and the first-2 revenue information 211b, and the display control means 52 may display the first function information 181 and the first-1 revenue information 211a in association with each other on the display unit 30, and also display the second function information 182 and the first-2 revenue information 211b in association with each other on the display unit 30. With this configuration, users can reliably grasp the first function information 181 and the corresponding first-1 revenue information 211a, as well as the second function information 182 and the corresponding first-2 revenue information 211b. This allows users to compare the first-1 revenue information 211a when an EMS with the first function is introduced with the first-2 revenue information 211b when an EMS with the second function is introduced. Therefore, users can easily consider whether to introduce the first or second function of the EMS.

[0092] Furthermore, the display control means 52 may display the EMS price information 190, which indicates the price of the EMS, in association with the first price information 111 and the first revenue information 211 on the display unit 30. With this configuration, the user can access EMS price information 190 and the corresponding first price information 111 and first revenue information 211. This allows the user to easily understand, for example, how much investment in EMS and battery systems will yield what kind of revenue.

[0093] Furthermore, the display control means 52 may display facility type information 170, which indicates the type of facility owned by the user introducing the battery storage system, along with the first price information 111 and the first revenue information 211, on the display unit 30 in association with each other. With this configuration, users can easily understand the type of facility owned by the user installing the battery storage system by checking the facility type information 170, and can also easily understand the first price information 111 and first revenue information 211 that correspond to the facility type information 170.

[0094] Furthermore, the display control means 52 may use first capacity information indicating the capacity of the first battery system instead of the first price information 111. By checking the first capacity information, the user can easily understand the capacity of the first battery storage system and reliably understand the first revenue information 211 corresponding to the first capacity information. This allows the user to easily understand, for example, how much revenue can be obtained depending on the capacity of the battery storage system.

[0095] Furthermore, the display control means 52 may display on the display unit 30 a second price information 112 indicating the price of the second battery system and a second revenue information 212 indicating the revenue obtained by controlling the second battery system by the EMS, in association with each other. With this configuration, users can reliably grasp the first price information 111 and the corresponding first revenue information 211, as well as the second price information 112 and the corresponding second revenue information 212. Therefore, users can easily understand, for example, how much the revenue information 210 changes due to differences in the price of battery storage systems. This allows them to compare battery storage systems at different prices and easily consider which battery storage system to install.

[0096] Furthermore, the display control means 52 may display the first remaining life information 120, which indicates the remaining life of the first battery system, along with the first price information 111 and the first revenue information 211, on the display unit 30 in association with each other. With this configuration, users can easily understand the remaining lifespan of the battery system by checking the remaining lifespan information 120, and can also understand the first price information 111 and first revenue information 211 that correspond to the remaining lifespan information 120. This allows users to consider, for example, the price of the battery system necessary to obtain the first revenue, taking its remaining lifespan into account.

[0097] The display control method of this disclosure includes a display control step of displaying in association with first price information 111 indicating the price of the first battery storage system and first revenue information 211 indicating the revenue obtained by controlling the first battery storage system by the EMS on the display unit 30, wherein the EMS outputs transaction instruction information indicating a power transaction instruction. With this configuration, users can, by looking at the display unit 30, confirm, for example, the costs associated with investing in a battery storage system or EMS, and how much revenue can be obtained from trading electricity through the EMS. Therefore, users can easily grasp the costs of introducing a battery storage system and EMS, as well as information regarding the operation of the battery storage system and EMS. Based on this information, users can decide whether or not to introduce a battery storage system or EMS.

[0098] The display control program of this disclosure causes a computer to function as the display control system 1 described in claim 1.
