Embodiments for Carrying Out the Invention

[0009] Hereinafter, with reference to the drawings, a power management system 100, a consideration calculation method, and a program according to an embodiment of the present disclosure will be described.

[0010] FIG. 1 is a diagram showing the relationship between an EMS operator 1 and a customer 2 on the premise of the introduction of the power management system 100. The EMS operator 1 provides the functions of the EMS to the customer 2. The customer 2, for example, owns or manages a facility. The facility includes a storage battery and power generation equipment. The facility is not particularly limited, and examples include a logistics warehouse, a plant, a building, and a house. Examples of the power generation equipment include power generation equipment using fossil energy and power generation equipment using renewable energy. The facility may further include power consumption equipment. Examples of the power consumption equipment include lighting equipment, air conditioning equipment, and general machinery. When the storage battery or the power generation equipment consumes power, it can be said that these storage batteries and power generation equipment are also power consumption equipment.

[0011] An EMS (Energy Management System) is, for example, a system for managing the demand and supply of electric power in a specific facility. By introducing an EMS, for example, optimization of the demand and supply of electric power (optimization of the power supply and demand plan) can be achieved. The demand includes, for example, the charge amount of a storage battery and the power consumption amount in power-consuming equipment. The supply includes, for example, the discharge amount of a storage battery and the power generation amount in power generation equipment. Further, in this embodiment, the EMS includes, in the demand and supply, the buying and selling of electric power in the market. The demand includes, for example, in addition to the above-mentioned charge amount and consumption amount, the amount of electricity sold. The supply includes, for example, in addition to the above-mentioned discharge amount and supply amount, the amount of electricity purchased. The optimization of the supply and demand plan by the EMS includes not only the optimization of the supply and demand plan limited within the target facility but also the optimization of the supply and demand plan including the market outside the target facility (for example, the power market). As a result, compared with the case where the EMS is not introduced, it may be possible to optimize the objective variable such as cost reduction. The EMS assumes, for example, various revenue opportunities (for example, trading profits in the spot market described later, sales in the environmental value market, FIP profits, profits in the supply and demand adjustment market, trading profits in the forward market, imbalance costs), and plans the power generation and power storage plan that maximizes the profit and the power trading partners (when, in which market, how much to trade and monetize).

[0012] The introduction of the EMS into the facility may include, for example, that the plan of the demand and supply of electric power (power supply and demand plan) in the facility is formulated by the EMS. In this embodiment, the power supply and demand plan includes the power trading plan as described above. The introduction of EMS to a facility may include, for example, the facility being controlled (the power consumption of the facility being controlled) based on the power supply and demand plan formulated by EMS. In this case, the role of EMS itself may be either of the following (1) or (2). For example, (1) EMS itself may directly control the facility. Further, for example, (2) EMS itself may only present the power supply and demand plan, and a person who has received the presentation of the supply and demand plan (for example, the administrator of the facility) or another device may control the facility. In the case of (2), the actual control of the power supply and demand of the facility may not be carried out by EMS itself. The introduction of EMS to a facility may include, for example, the power supply and demand plan formulated by EMS being changed in response to changes in the environment (prerequisites), and the facility being controlled based on the changed power supply and demand plan. The detailed functions of EMS will be described later.

[0013] EMS provider 1 may provide the functions of EMS to each of a plurality of customers 2. By introducing EMS to the facility, customer 2 of EMS can obtain benefits as described above. EMS provider 1 obtains consideration for the provision of the functions of EMS from each customer 2. In the present embodiment, EMS provider 1 obtains a part of the above-mentioned benefits as consideration from customer 2 of EMS. The power management system 100 according to the present embodiment implements the functions of EMS and calculates this consideration. In the example shown in FIG. 1, for the sake of clarity, EMS is shown as being included in each customer. However, EMS may be provided by a cloud service. For example, EMS may include an EMS cloud and an EMS gateway. In this case, the EMS cloud may formulate operation plans for power generation facilities, storage batteries, and power trading. And in order to control the power generation facilities and storage battery facilities owned by the customer according to the operation plan, an instruction signal may be sent from the EMS cloud to the EMS gateway installed at each site. Furthermore, the EMS gateway may rewrite the set values of the power generation facilities and storage battery facilities owned by the customer. Thereby, the control systems of the power generation facilities and storage facilities owned by the customer may control the power generation facilities and storage facilities.

[0014] FIG. 2 is a schematic block diagram showing the system configuration of the power management system 100 of the present disclosure. The power management system 100 includes a management device 10 (consideration calculation device) and a trading device 20. The management device 10 and the trading device 20 are communicably 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 be configured by combining a plurality of networks.

[0015] The power management system 100 is owned or managed by the operator 1 of the EMS. The management device 10 implements the functions of the EMS. The management device 10 calculates the consideration for the operator 1 to provide the functions of the EMS to the customer 2. The trading device 20 is connected to, for example, a power trading market (not shown) and an environmental value trading market (not shown) via the network 70. The trading device 20 conducts trading of electric power and environmental values for each facility. The management device 10 and the trading device 20 may each be provided for each facility or may be provided in common for a plurality of facilities.

[0016] (Management device 10) FIG. 3 is a schematic block diagram showing a specific example of the functional configuration of the management device 10. The management device 10 is configured using an information device (information processing device) such as a smartphone, a tablet, a personal computer, a dedicated device, or a server device. The management device 10 includes a communication unit 11, an input unit 12, an output unit 13, a storage unit 14, and a control unit 15.

[0017] 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 performs data communication with other devices via a network according to the control of the control unit 15. The communication unit 11 may be a device that performs wireless communication or a device that performs wired communication.

[0018] The input unit 12 is configured using existing input devices such as a keyboard, a pointing device (mouse, tablet, etc.), buttons, a touch panel, etc. The input unit 12 is operated by the user when inputting the user's instruction to the management device 10. The input unit 12 may be an interface for connecting the input device to the management device 10. In this case, the input unit 12 inputs an input signal generated according to the user's input in the input device to the management device 10. The input unit 12 may be configured using a microphone and a voice recognition device. In this case, the input unit 12 acquires an acoustic signal generated by the user's speech, recognizes the words spoken by the user, and inputs the string information of the recognition result to the management device 10. The voice recognition process may be executed by the control unit 15. The input unit 12 may be configured in any way as long as it can input the user's instruction to the management device 10.

[0019] The output unit 13 outputs information in a form recognizable by the user. The output unit 13 may be, for example, an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The output unit 13 may also be an interface for connecting the image display device to the management 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 itself. The output unit 13 may be a device that outputs sound such as a speaker. The output unit 13 may also be an interface for connecting an acoustic output device such as a speaker or headphones to the management device 10. In this case, the output unit 13 generates an acoustic signal for reproducing acoustic data and outputs the acoustic signal to the acoustic output device connected to itself. The output unit 13 may be, for example, a printer. The output unit 13 may also be an interface for connecting the printer to the management 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 itself. Note that the output unit 13 may be configured as a touch panel integrated with the input unit 12.

[0020] The storage unit 14 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 14 stores data used by the control unit 15. The storage unit 14 stores data required when the control unit 15 performs processing. The storage unit 14 functions, for example, as a function information storage unit 141.

[0021] The function information storage unit 141 stores function information. The function information is information related to functions. The functions are the functions of the EMS. The format of the function information stored by the function information storage unit 141 will be described later.

[0022] The control unit 15 is configured using a processor such as a CPU (Central Processing Unit) and a memory (main storage device). The control unit 15 functions as an EMS execution means 151, an EMS price calculation means 152, a price presentation means 153, and a ratio presentation means 154 when the processor executes a program. Note that all or part of each function of the control unit 15 may be realized using hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The above program may be recorded on a computer-readable recording medium. A computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, a semiconductor memory device (e.g., SSD: Solid State Drive), or a storage device such as a hard disk or a semiconductor memory device built into a computer system. The above program may be transmitted via a telecommunication line.

[0023] The control unit 15 may execute, for example, an application installed in the own device (management device 10). As a specific example of such an application, there is an application provided to the management device 10 as a dedicated application of the power management system 100. As another specific example of such an application, there is a WEB browser application. Such an application may be installed in the management device 10 in advance, or may be downloaded each time the determination process is executed. For example, when implemented as a WEB browser application, when the management device 10 connects to a specific WEB server, the management device 10 may download and execute the application from a device specified by the WEB server (for example, the WEB server itself or another server). The control unit 15 operates according to the program of the running application.

[0024] The EMS execution means 151 executes processing related to the EMS. The processing related to the EMS may include, for example, (A) formulating a power supply and demand plan for each facility, (B) implementing the formulated power supply and demand plan, and (C) controlling the facility based on the changed power supply and demand plan while changing the power supply and demand plan formulated by the EMS according to changes in the environment (prerequisites). The processing (function of the EMS) related to the EMS may be the formulation of a power supply and demand plan. The formulation of a power supply and demand plan may include the formulation of a power generation and storage plan and the formulation of a market trading plan.

[0025] The EMS execution means 151 formulates (A) a power supply and demand plan for each facility. The EMS execution means 151 formulates, for example, a plan such that optimization of a predetermined objective variable is achieved at each facility. The objective variable may be, for example, a monetary profit (cost) or an environmental load (e.g., CO2 emission amount, etc.). In this embodiment, the objective variable is profit. The EMS execution means 151 may implement, for example, a machine-learned artificial intelligence, and this artificial intelligence may formulate the plan. The EMS execution means 151 may implement, for example, a known algorithm, and the plan may be formulated by this algorithm.

[0026] In formulating the supply and demand plan, information such as the power generation amount, demand amount, and market price of power (selling price of power, buying price of power) in the facility may be predicted by the EMS execution means 151 (e.g., artificial intelligence) or may be given in advance. The EMS execution means 151 formulates a power plan that optimizes the objective variable based on the above-described respective information. For example, when the objective variable is cost, the EMS execution means 151 formulates a plan for the power supply amount (generation amount), demand amount, selling amount, and buying amount of power such that the cost is optimized while satisfying the power demand. The EMS execution means 151 may formulate, for example, a power generation plan by a power generation facility, an operation plan for a rechargeable battery (plan for charge and discharge amount), a sales plan for surplus power, and a purchase plan for insufficient power.

[0027] The EMS implementation means 151 implements the power supply and demand plan formulated in (B). The implementation of the power supply and demand plan by the EMS implementation means 151 may include, for example, the EMS implementation means 151 controlling each facility based on the formulated supply and demand plan, presenting the formulated supply and demand plan to the people related to each facility or other devices related to each facility, or implementing processing regarding the buying and selling of power for each facility based on the formulated supply and demand plan. The EMS implementation means 151 implementing processing regarding the buying and selling of power for each facility based on the formulated supply and demand plan may be, for example, outputting power trading instruction information (for example, power supply and demand plan information, operation plan information) to the trading device 20. The power trading instruction information is information used for power trading. For example, the power trading instruction information may be data in which a time zone is associated with the amount of power sold or purchased required for the corresponding time zone. The power trading instruction information may include not only information related to the trading of power itself but also information related to the trading of environmental value based on the generation of renewable energy.

[0028] The EMS implementation means 151 controls the facility based on the changed power supply and demand plan while changing the power supply and demand plan formulated by the EMS according to changes in the environment (prerequisite conditions). It can be said that the function related to this (C) varies greatly according to the environment, is more complex than the functions related to (A) and (B), and is a difficult-to-realize function. While the functions related to (A) and (B) are the basic functions of the EMS, the function related to (C) can be said to be an extended function of the EMS.

[0029] The EMS realized by such EMS implementation means 151 includes a first function and a second function different from the first function. Examples of the first function include (1) the function of buying and selling power in the supply and demand adjustment market, (3) the function of buying and selling power in the time-ahead market, (3) the function of buying and selling power in multiple markets, and (4) the imbalance avoidance function. Examples of the second function include (5) the function of buying and selling power in the spot market, (6) the function of obtaining income through FIP, (7) the function of obtaining income through environmental value, and (8) the peak shifting function. Each of these functions may also include formulating a power generation and storage plan and a market trading plan (formulating a power supply and demand plan) after considering each function. For example, the function of buying and selling electricity in the supply and demand adjustment market may include the EMS formulating a power supply and demand plan after considering buying and selling electricity in the supply and demand adjustment market. For example, the function of buying and selling electricity in the pre-time market may include the EMS formulating a power supply and demand plan after considering buying and selling electricity in the pre-time market. For example, the function of buying and selling electricity in multiple markets may include the EMS formulating a power supply and demand plan after considering buying and selling electricity in multiple markets. For example, the imbalance avoidance function may include the EMS formulating a power supply and demand plan after considering imbalance avoidance. For example, the function of buying and selling electricity in the spot market may include the EMS formulating a power supply and demand plan after considering buying and selling electricity in the spot market. For example, the function of obtaining income through FIP may include the EMS formulating a power supply and demand plan after considering obtaining income through FIP. For example, the function of obtaining income through environmental value may include the EMS formulating a power supply and demand plan after considering obtaining income through environmental value. For example, the peak shifting function may include the EMS formulating a power supply and demand plan after considering peak shifting. The benefits obtained by introducing the EMS into the facility are obtained by introducing the first function and the second function into the facility. Hereinafter, these first function and second function will be described.

[0030] First, the (5) to (7) related to the second function will be described. The (5) to (7) related to the second function are functions related to general electricity trading related to the above (A) and (B).

[0031] Regarding the buying and selling of electricity, the EMS formulates, for example, the trading plan for the next day by 12:00 on the previous day and sends it to 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 an organization that aggregates plans from each electric utility, for example. When buying and selling electricity in accordance with this plan, it is traded in the spot market according to (5) above. And when electricity is sold in the market, if the electricity is generated based on renewable energy, the Feed In Premium (FIP) according to (6) above is added to the normal electricity price. FIP is the value added to electricity generated by renewable energy power generation. This added value may be, for example, a subsidy by a public institution such as a country or a local government. By the way, when electricity is renewable energy, an environmental value according to (7) above is generated in the generated electricity. This environmental value can be traded, for example, in an environmental value trading market different from the electricity market (for example, a non-fossil value trading market). As a basic function of the EMS, it aims to maximize the profit obtained from the trading in the spot market according to (5) and (6) and the FIP associated with the trading, and the trading of the environmental value according to (7).

[0032] The peak shifting function according to (8) above is one function related to the formulation of the plan. The peak shifting function is a function that implements the leveling of the electricity supply and demand. When the peak shifting function implements the leveling of the electricity demand, for example, the electricity demand in a time period with a high demand (for example, daytime electricity consumption) is allocated to the electricity demand in a time period with a low demand (for example, nighttime electricity consumption). The allocation of the electricity demand is realized, for example, by changing the time period when the rechargeable battery is charged. When the peak shifting function implements the leveling of the electricity supply, for example, the electricity supply in a time period with a high supply is allocated to the electricity supply in a time period with a low supply. The allocation of the electricity supply is realized, for example, by changing the time period when the power generation facility generates electricity. By virtue of the peak shifting function according to (8), the EMS can, for example, reduce the power purchased from the spot market according to (5), and can further increase the profit obtained by the functions according to (5) to (7). Regarding the peak shifting function according to (8), for example, it may function as a part of other functions such as the function of buying and selling the power according to (5) and (6) in the spot market, the function of obtaining income through FIP, etc. That is, the plan formulated considering the buying and selling of power in the spot market may be a plan with peak shifting as a result.

[0033] Next, the above (1) to (4) related to the first function will be described. The above (1) to (4) related to the first function are mainly extended functions related to the buying and selling of the power according to (C).

[0034] The supply and demand adjustment market related to (1) is a market for regulation power. The supply and demand adjustment market is a market for procuring the regulation power necessary for adjusting the power supply and demand balance. The supply and demand adjustment market is soliciting bids for regulation power. Those who own power sources (for example, storage batteries and power generation facilities) bid in the solicitation of the supply and demand adjustment market, and when winning the bid, they have the right to supply power as regulation power. When a person who owns a power source wins the bid for regulation power and when the regulation power is activated, the person supplies power as regulation power. Even when a person who owns a power source wins the bid for regulation power, if the regulation power is not activated, the person does not supply power as regulation power. When a person who owns a power source wins the bid for regulation power, the person obtains income corresponding to the amount of power of the winning regulation power. Further, when a person who owns a power source supplies power as regulation power when the regulation power is activated, the person can obtain the profit from selling electricity to the regulation power market (income corresponding to the amount of supplied power).

[0035] The electricity sales in the supply and demand adjustment market related to (1) like this require, for example, a formulated operation plan depending on whether it is activated, and an extended function of the EMS according to (C) is required. For example, when formulating a plan on the premise of the activation of regulation power, if the regulation power is not activated, the plan needs to be changed.

[0036] Examples of the adjustment power include primary adjustment power, secondary adjustment power (secondary adjustment power (1), secondary adjustment power (2)), tertiary adjustment power (tertiary adjustment power (1), tertiary adjustment power (2)), etc. These adjustment powers differ, for example, in response time and duration. The response time is, for example, the upper limit of the interval from the time when the adjustment power is activated to the time when power supply starts. The response time of the primary adjustment power is, for example, within 10 seconds, the response time of the secondary adjustment power (1) and (2) is, for example, within 5 minutes, the response time of the tertiary adjustment power (1) is, for example, within 15 minutes, and the response time of the tertiary adjustment power (2) is, for example, within 45 minutes. The duration is, for example, the minimum time during which power supply can continue from the time when the adjustment power is activated. The duration of the primary adjustment power is, for example, 5 minutes or more, the duration of the secondary adjustment power (1) and (2) is, for example, 30 minutes or more, and the duration of the tertiary adjustment power (1) and (2) is, for example, 3 hours. When the response time is short, discharging from the storage battery is preferred because power sales in a short period are required. When the duration is long, power generation by the power generation facility is preferred because power sales over a long period are required.

[0037] The time pre-market related to the above (2) is, for example, a market in which transactions can be made until 1 hour before the actual supply and demand. As described above, trading plans are sent to the OCCTO, and a power generation plan, a sales plan corresponding thereto, a demand plan, and a procurement plan corresponding thereto are submitted. However, in the actual supply and demand section, differences in the actual power generation amount and demand amount occur with respect to the trading plan sent to the OCCTO, and differences may occur between the actual sales volume, procurement, and the sales plan and procurement plan. Such differences (imbalances) are caused, for example, by failures of power generation facilities. Specifically, the following shortage imbalances and surplus imbalances occur in the actual supply and demand section. · When the power generation amount decreases, the actual sales volume decreases. The difference between the actually decreased sales volume and the sales plan becomes a shortage imbalance. ·When the power generation increases, the actual sales volume increases. The difference between the actually increased sales volume and the sales plan becomes the surplus imbalance. ·When the demand increases, the actual procurement volume increases. The difference between the actually increased procurement volume and the procurement plan becomes the shortage imbalance. ·When the demand decreases, the actual procurement volume decreases. The difference between the actually decreased procurement volume and the procurement plan becomes the surplus imbalance. When surplus imbalances or shortage imbalances as described above occur, for final adjustment, for example, the marginal cost required by the former general electricity undertaker is used as the imbalance unit price and imbalance cost, and Customer 2 (electricity undertaker) will bear it. Note that the shortage imbalance fee and surplus imbalance fee are obtained as follows, for example. Shortage imbalance fee (the cost for the general power transmission and distribution undertaker to make up for the shortfall in actual performance compared to the plan) = (weighted average value of the spot market and the pre-time market) × α + β + K Surplus imbalance fee (the cost for the general power transmission and distribution undertaker to purchase the surplus in actual performance compared to the plan) = weighted average value of the spot market and the pre-time market × α + β - L α: Adjustment term according to the supply and demand situation of the entire system β: Adjustment term reflecting the market price difference for each region K, L: Incentive constants Since Customer 2 (electricity undertaker) needs to strive to minimize such imbalances, when an imbalance is expected to occur and trading is possible in the pre-time market, for example, it tries to conduct transactions in the pre-time market to eliminate the imbalance. Such a function of buying and selling electricity in the pre-time market as described in (2) becomes an extended function of the EMS related to the above (C).

[0038] Regarding the function of buying and selling electricity in multiple markets (3), it is naturally more complex because multiple factors need to be considered compared to the case of buying and selling in a single market. Note that 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-demand adjustment market. Also, buying and selling electricity in multiple markets may include, for example, buying and selling electricity as primary and secondary frequency control reserves (1) in the supply-demand adjustment market (buying and selling as different commodities in the same market).

[0039] The imbalance avoidance related to (4) is, for example, when there are differences in the actual power generation and demand compared to the trading plan sent to the OCCTO, resulting in differences between the actual sales volume, procurement volume and the sales plan, procurement plan. For example, it is implemented when the imbalance cannot be resolved even in the case of forward trading as described above. For example, in the case of solar power generation, the power generation amount varies depending on the weather of the day, and an imbalance may occur. At this time, when the imbalance cannot be resolved even by implementing forward trading, for example, the shortage imbalance may be avoided by discharging from the battery or generating power from other power generation facilities. Furthermore, at this time, the surplus imbalance may be avoided by, for example, charging the battery or stopping the power generation of other power generation facilities. The imbalance avoidance related to (2) is an extended function of the EMS related to (C).

[0040] As described above, the EMS implementation means 151 performs processing (information processing) related to each of the first function and the second function. The EMS implementation means 151 realizes the first function and the second function by means of artificial intelligence and algorithms as described above. The information processing used for predicting the profit obtained by introducing the first function into the facility is more complex than the information processing used for predicting the profit obtained by introducing the second function into the facility. For example, in order to obtain profit by the first function, it is necessary to consider transactions in various markets, which is complex, so it can be said that it is more difficult to accurately predict than in the case of obtaining profit by the second function. Thus, the foreseeability of obtaining profit by introducing the first function into the facility is lower than the foreseeability of obtaining profit by introducing the second function into the facility. The profit obtained by introducing the first function into the facility has greater volatility (fluctuation) than the profit obtained by introducing the second function into the facility. And the EMS realized by the EMS implementation means 151 is premised on the buying and selling of electricity. It can be said that this EMS implements the basic function of formulating a power supply and demand plan and outputs power trading instruction information. The EMS outputs, for example, power trading instruction information to the trading device 20.

[0041] The EMS price calculation means 152 calculates the price for introducing EMS into the facility. The EMS price calculation means 152 takes a part of the profit obtained by introducing EMS into the facility as the price. The price includes a first price and a second price. The EMS price calculation means 152 takes a part of the profit obtained by introducing the first function into the facility as the first price, and takes a part of the profit obtained by introducing the second function into the facility as the second price. Note that the EMS price calculation means 152 may be able to calculate the profit for each function of the EMS implementation means 151. The profit for each function of the EMS implementation means 151 may be, for example, the profit obtained more when the algorithm (program) for implementing the function of the EMS implementation means 151 is executed compared to when the algorithm is not executed. In this case, the EMS price calculation means 152 may multiply the profit calculated for each function by the rate per unit period set for each function to obtain the price for each function. The rate per unit period is the ratio of the price obtained by the operator 1 to the profit obtained by the customer 2 by introducing EMS.

[0042] For the description of the EMS price calculation means 152, a specific example of the function information stored in the function information storage unit 141 of the storage unit 14 will be described. FIG. 4 is a diagram showing a specific example of the function information table stored in the function information storage unit 141. The function information table has a plurality of function information records. The function information record has values of an identification number, a function name, a function attribute, and a rate per unit period. The identification number is a unique identification number corresponding to each function. The function name is a unique name used for the function corresponding to the identification number. The function attribute is information indicating whether the function corresponding to the identification number belongs to either the first function or the second function. The rate per unit period is the rate set for the function corresponding to the identification number in the corresponding unit period. The unit period may be, for example, a year (e.g., January to December, April to the following March, September to the following August), a month (e.g., the 1st to the end of the month, the 16th to the 15th of the following month), or other periods (e.g., half a year, etc.).

[0043] The EMS price calculation means 152 may be able to calculate the profit for each function of the EMS execution means 151 and for each unit period. The EMS price calculation means 152 may, for example, multiply the profit calculated for each function of the EMS execution means 151 and for each unit period by the rate per function and per unit period stored in the function information storage unit 141 as shown in FIG. 4 to obtain the price for each function. However, the rate may only be set for each function and may not be set for each unit period. Here, as described above, since higher-level processing is required for the first function compared to the second function, in this embodiment, the rate for each function belonging to the first function is higher than the rate for each function belonging to the second function. As a result, the ratio of the first price to the profit obtained by introducing the first function into the facility is larger than the ratio of the second price to the profit obtained by introducing the second function into the facility.

[0044] FIG. 5 is a diagram showing an example of the user interface presented by the price presentation means 153 and the ratio presentation means 154.

[0045] As shown in FIG. 5, the price presentation means 153 presents the first function information and the first price to the user in association with each other, and presents the second function information and the second price to the user in association with each other. The first function information is information indicating the first function, and the second function information is information indicating the second function. Here, the price presentation means 153 presenting various information may mean that the price presentation means 153 displays the various information on a display surface such as the screen of an image display device or the paper surface of a printed matter, or in an electronic file, or may output it as voice. The user may be, for example, a person related to the facility (for example, a facility manager, a facility owner, or a person considering the introduction of EMS).

[0046] The ratio presentation means 154 presents the first function information and the first ratio information to the user in association with each other, and presents the second function information and the second ratio information to the user in association with each other. The first ratio information is information indicating the ratio of the first consideration, and the second ratio information is information indicating the ratio of the second consideration. Here, the ratio presentation means 154 presenting various information may be the ratio presentation means 154 displaying various information on a display surface such as the screen of an image display device or the paper surface of a printed matter, or in an electronic file, or outputting it by voice.

[0047] In the illustrated example, the consideration presentation means 153 and the ratio presentation means 154 display various information as the first table T1 on the display surface 30. The first table T1 includes one heading row T1a and a plurality of record rows T1b.

[0048] The heading row T1a is the top row in the first table T1. The heading row T1a represents the content indicated by the information of each cell (information cell T1d) in the record row T1b. In the present embodiment, each heading in the heading row T1a is, for example, the X-year rate, X-year income, X-year fee, Y-year rate, Y-year income, Y-year fee. The X-year rate is the X-year rate stored in the function information table. The X-year income and the X-year fee are the profit and consideration for each function calculated by the EMS consideration calculation means 152. The same applies to the Y-year rate, Y-year income, and Y-year rate with different unit periods.

[0049] Each record row T1b represents the rate, profit, and consideration for the function corresponding to each record row T1b. The record row T1b includes a heading cell T1c and an information cell T1d. The heading cell T1c is the first cell in the record row T1b. The heading cell T1c indicates which function the corresponding record row T1b is.

[0050] In addition, when the first table T1 is displayed on, for example, an image display device, the input unit 12 may enable the operation of the first table T1, and the control unit 15 may receive an input for changing the rate from the input unit 12. When receiving the change in the rate, the control unit 15 may update the contents of the first table T1 and the function information.

[0051] FIG. 6 is a diagram showing an example of a user interface presented by the consideration presenting means 153 and the ratio presenting means 154. As in the first table T1 of the modified example shown in FIG. 6, the consideration presenting means 153 and the ratio presenting means 154 may display on the display surface 30 a plurality of functions grouped by attribute (for example, the first attribute and the second attribute) and then display them as the first table T1.

[0052] In this embodiment, the EMS consideration calculation means 152 calculates the profit for each function of the EMS execution means 151, but it is not necessary to calculate the profit for each function. The EMS consideration calculation means 152 may calculate the total profit for a specific period and calculate the consideration at a uniform rate (for example, a rate between the first rate and the second rate) regardless of the function. In this case, the control unit 15 may simply present the consideration and the ratio in association with each other to the user. Further, in addition to calculating the profit for each function, the EMS consideration calculation means 152 may calculate the profit for each facility of the target facility and set the rate for each facility.

[0053] (Trading device 20) The trading device 20 is configured by using an information device (information processing device) such as a smartphone, a tablet, a personal computer, a dedicated device, or a server device. The trading device 20 conducts transactions with the market based on the trading instruction information received from the management device 10.

[0054] (Consideration calculation method) Hereinafter, the consideration calculation method implemented by the management device 10 will be described. In the consideration calculation method, for example, it is premised that the management device 10 conducts operations for a predetermined unit period and that profit is generated for the customer 2 of the EMS by the management (processing by the EMS) by the management device 10.

[0055] FIG. 7 is a flowchart showing an example of a consideration calculation method using the management device 10. The consideration calculation method includes an EMS consideration calculation step S101 and a presentation step S102.

[0056] First, the management device 10 performs the EMS consideration calculation step S101. In the EMS consideration calculation step S101, the EMS consideration calculation means 152 calculates the consideration for introducing EMS into the facility. In the EMS consideration calculation step S101, the EMS consideration calculation means 152 uses a part of the profit obtained by introducing EMS into the facility as the consideration. The EMS consideration calculation means 152 calculates the consideration, for example, by multiplying the profit amount for each function obtained by the EMS execution means 151 by the rate stored in the function information storage unit 141.

[0057] Next, the management device 10 performs the presentation step S102. In the presentation step S102, the consideration presentation means 153 presents the consideration as shown in FIG. 5. At this time, in the present embodiment, the consideration presentation means 153 associates and presents the first function information and the first consideration to the user, and also associates and presents the second function information and the second consideration to the user (consideration presentation step). Further, at this time, in the present embodiment, the ratio presentation means 154 associates and presents the first function information and the first ratio information to the user, and also associates and presents the second function information and the second ratio information to the user (ratio presentation step). At this time, the consideration presentation means 153 and the ratio presentation means 154 present to the user, for example, by associating the consideration calculated by the EMS consideration calculation means 152 and the storage information stored in the function information storage unit 141.

[0058] The consideration calculation method ends here. Note that the presentation step S102 may not be provided.

[0059] As described above, according to the power management system 100 according to the present embodiment, the EMS price calculation means 152 uses, as the price, a part of the profit obtained by introducing, into the facility, the EMS that outputs the power trading instruction information. Therefore, the EMS operator 1 can actively propose to the customer 2 considering the introduction of the EMS an EMS that generates a high profit with, as one factor, outputting the power trading instruction information. Furthermore, the customer 2 considering the introduction of the EMS can enjoy a part of the high profit thus generated (the remainder after excluding the price from the profit), and can actively introduce the EMS because the price can be covered by a part of the profit thus generated.

[0060] The EMS price calculation means 152 uses, as the first price, a part of the profit obtained by introducing the first function into the facility, and uses, as the second price, a part of the profit obtained by introducing the second function into the facility. Therefore, the EMS operator 1 can obtain the function by the first function as the first price, and can obtain the function by the second function as the second price.

[0061] The price presentation means 153 presents to the user the first function information and the first price in association with each other, and presents to the user the second function information and the second price in association with each other. Therefore, for example, the customer 2 considering the introduction of the EMS can associate and grasp the first price and the first function that is the function used to obtain the first price, and can associate and grasp the second price and the second function that is the function used to obtain the second price. Thereby, the customer 2 considering the introduction of the EMS can, for example, enhance the sense of acceptance for the price for each function that can obtain the profit.

[0062] The ratio presentation means 154 presents to the user by associating the first function information with the first ratio information and by associating the second function information with the second ratio information. Thus, for example, a customer 2 who is considering introducing EMS grasps by associating a first ratio indicating the ratio of the first consideration to the profit with a first function which is the function used to obtain the first consideration, and also grasps by associating a second ratio indicating the ratio of the second consideration to the profit with a second function which is the function used to obtain the second consideration. Thereby, the customer 2 who is considering introducing EMS can, for example, enhance the sense of acceptance with respect to the consideration for each function that can obtain a profit.

[0063] The ratio of the first consideration in the profit obtained by introducing the first function into the facility is larger than the ratio of the second consideration in the profit obtained by introducing the second function into the facility. Thus, for example, the EMS provider 1 can obtain different ratios of consideration for each function that can obtain a consideration. The customer 2 who is considering introducing EMS can, for example, enhance the sense of acceptance with respect to the consideration for each function that can obtain a profit.

[0064] The predictability that a profit can be obtained by introducing the first function into the facility is lower than the predictability that a profit can be obtained by introducing the second function into the facility. Thus, the consideration is set for each function with different predictability of obtaining a profit. For example, when the ratio of the first consideration in the profit obtained by introducing the first function into the facility is larger than the ratio of the second consideration in the profit obtained by introducing the second function into the facility, etc., the ratio of the first consideration which is a function with low predictability of obtaining a profit becomes lower than the ratio of the second consideration which is a function with high predictability of obtaining a profit. In this case, the customer 2 who is considering introducing EMS can, for example, enhance the sense of acceptance with respect to the consideration for each function that can obtain a profit.

[0065] (Hardware Configuration of Each Device) FIG. 8 is a diagram showing an outline of a hardware configuration example of an information processing apparatus 90 to which the present embodiment is applied. The information processing apparatus 90 includes a processor 91, a main memory device 92, a communication interface 93, an auxiliary storage device 94, an input / output interface 95, and an internal bus 96. The processor 91, the main memory device 92, the communication interface 93, the auxiliary storage device 94, and the input / output interface 95 are communicably connected to each other via the internal bus 96. The information processing apparatus 90 may be applied to, for example, the management apparatus 10 and the trading apparatus 20. In this case, for example, the communication unit 11 may be configured using the communication interface 93. For example, the storage unit 14 may be configured using the auxiliary storage device 94. Further, the control unit 15 may be configured using the processor 91 and the main memory device 92.

[0066] The operations of the control unit described above are stored in the auxiliary storage device 94 (storage) in the form of a program. The processor 91 reads the program from the auxiliary storage device 94 and expands it in the main memory device 92, and executes the above processing according to the program. Further, the processor 91 secures a storage area corresponding to each of the above storage units in the main memory device 92 according to the program. Examples of the processor 91 include a CPU (Central Processing Unit), a GPU (Graphic Processing Unit), and a microprocessor.

[0067] The program may be for realizing a part of the functions to be exerted by the information processing apparatus 90. For example, the program may exert functions in combination with other programs already stored in the auxiliary storage device 94 or in combination with other programs implemented in other devices. In other examples of the embodiment, the information processing apparatus 90 may include a custom LSI (Large Scale Integrated Circuit) such as a PLD (Programmable Logic Device) in addition to or instead of the above configuration. Examples of the PLD include PAL (Programmable Array Logic), GAL (Generic Array Logic), CPLD (Complex Programmable Logic Device), and FPGA (Field Programmable Gate Array). In this case, some or all of the functions realized by the processor 91 may be realized by the integrated circuit. Such an integrated circuit is also included as an example of a processor.

[0068] Examples of the auxiliary storage device 94 include a magnetic disk, a magneto-optical disk, an optical disk, a semiconductor memory, etc. The auxiliary storage device 94 may be an internal medium directly connected to the bus of the information processing apparatus 90, or may be an external medium connected to the information processing apparatus 90 via the input / output interface 95 or a communication line. Also, when this program is distributed to the information processing apparatus 90 via a communication line, the information processing apparatus 90 that has received the distribution may expand the program in the main storage device 92 and execute the above processing. In at least one embodiment, the auxiliary storage device 94 is a non-transitory tangible storage medium.

[0069] Also, the program may be for realizing a part of the functions described above. Furthermore, the program may be a so-called difference file (difference program) that realizes the functions described above in combination with other programs already stored in the auxiliary storage device 94.

[0070] For example, the program may be a program for causing a computer (information processing apparatus) to function as the management device 10.

[0071] As described above, the embodiments of this disclosure have been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and designs and the like within the scope not departing from the gist of this disclosure are also included.

[0072] For example, the ratio presentation means 154 may not be provided. For example, the consideration presentation means 153 may not be provided. The consideration presentation means 153 may not present the correspondence between the function and the consideration, and the consideration presentation means 153 may simply present the consideration. For example, the EMS implementation means 151 may not be provided. The management device 10 may function as a consideration calculation system that mainly calculates the consideration without implementing the EMS.

[0073] (Appendix) The above embodiment is understood as follows, for example.

[0074] <1>A consideration calculation system according to an aspect of the present invention includes an EMS consideration calculation means for calculating the consideration for introducing the EMS into a facility including a storage battery and power generation facilities. The EMS outputs power trading instruction information, and the EMS consideration calculation means uses a part of the profit obtained by introducing the EMS into the facility as the consideration.

[0075] The EMS price calculation means uses, as the price, a part of the profit obtained by introducing into the facility an EMS that outputs power trading instruction information. Therefore, it becomes possible for the EMS operator to actively propose to customers who are considering introducing an EMS an EMS that generates high profits with the factor of outputting power trading instruction information. Furthermore, customers who are considering introducing an EMS can enjoy a part of the high profit thus generated (the remainder after excluding the price from the profit), and since the price can be covered by a part of the profit thus generated, it becomes possible to actively introduce the EMS.

[0076] <2>In the price calculation system according to <1> above, the EMS includes a first function, and the profit is obtained by introducing the first function into the facility. A configuration characterized by this may be adopted.

[0077] The profit is obtained by introducing the first function into the facility. Therefore, the EMS operator can more surely obtain the price due to the first function.

[0078] <3>In the price calculation system according to <2> above, the EMS includes a second function different from the first function, and the profit is obtained by introducing the first function and the second function into the facility. A configuration characterized by this may be adopted.

[0079] The profit is obtained by introducing the first function and the second function into the facility. Therefore, the EMS operator can more surely obtain the price due to both the first function and the second function.

[0080] <4>In the price calculation system according to <3> above, the price includes a first price and a second price, and the EMS price calculation means uses, as the first price, a part of the profit obtained by introducing the first function into the facility, and uses, as the second price, a part of the profit obtained by introducing the second function into the facility. A configuration characterized by this may be adopted.

[0081] The EMS consideration calculation means sets a part of the profit obtained by introducing the first function into the facility as the first consideration, and a part of the profit obtained by introducing the second function into the facility as the second consideration. Therefore, the EMS operator can obtain the function by the first function as the first consideration and the function by the second function as the second consideration.

[0082] <5>In the consideration calculation system according to <4> above, the consideration presentation means further includes presenting the user with the first function information indicating the first function and the first consideration associated with each other, and presenting the user with the second function information indicating the second function and the second consideration associated with each other. You may adopt a configuration characterized by this.

[0083] The consideration presentation means presents the user with the first function information and the first consideration associated with each other, and presents the user with the second function information and the second consideration associated with each other. Therefore, for example, a customer considering the introduction of EMS can grasp the first consideration and the first function, which is the function used to obtain the first consideration, in association with each other, and can grasp the second consideration and the second function, which is the function used to obtain the second consideration, in association with each other. As a result, a customer considering the introduction of EMS can, for example, enhance the sense of acceptance for the consideration for each profit-obtaining function.

[0084] <6>In the consideration calculation system according to <4> or <5> above, the ratio of the first consideration to the profit obtained by introducing the first function into the facility is larger than the ratio of the second consideration to the profit obtained by introducing the second function into the facility. You may adopt a configuration characterized by this.

[0085] The ratio of the first consideration to the profit obtained by introducing the first function into the facility is larger than the ratio of the second consideration to the profit obtained by introducing the second function into the facility. Therefore, the EMS operator can obtain different ratios of consideration for each function that can obtain consideration. For example, a customer considering the introduction of EMS can enhance the sense of acceptance for the consideration for each profit-obtaining function.

[0086] <7>In the consideration calculation system according to any one of the above aspects <4> to <6>, the first function information indicating the first function and the first ratio information indicating the ratio of the first consideration are presented to the user in association with each other, and the second function information indicating the second function and the second ratio information indicating the ratio of the second consideration are presented to the user in association with each other. A configuration may be adopted which further includes a ratio presentation means.

[0087] The ratio presentation means presents the first function information and the first ratio information to the user in association with each other, and presents the second function information and the second ratio information to the user in association with each other. Thus, for example, a customer considering the introduction of EMS can associate and grasp the first ratio indicating the ratio of the first consideration to the profit and the first function which is the function used to obtain the first consideration, and can associate and grasp the second ratio indicating the ratio of the second consideration to the profit and the second function which is the function used to obtain the second consideration. Thereby, a customer considering the introduction of EMS can, for example, enhance the sense of acceptance of the consideration for each function that can obtain profit.

[0088] <8>In the consideration calculation system according to any one of the above aspects <3> to <7>, the predictability that profit can be obtained by introducing the first function into the facility is lower than the predictability that profit can be obtained by introducing the second function into the facility. A configuration may be adopted which is characterized by this.

[0089] The predictability of obtaining benefits by introducing the first function into the facility is lower than the predictability of obtaining benefits by introducing the second function into the facility. Therefore, a consideration is set for each function with different predictability of obtaining benefits. For example, when the ratio of the first consideration to the profit obtained by introducing the first function into the facility is larger than the ratio of the second consideration to the profit obtained by introducing the second function into the facility, etc., the ratio of the first consideration, which is a function with low predictability of obtaining benefits, becomes lower than the ratio of the second consideration, which is a function with high predictability of obtaining benefits. In this case, a customer considering the introduction of EMS can, for example, enhance the sense of acceptance for the consideration for each function that can obtain benefits.

[0090] <9>In the consideration calculation system according to any one of the above aspects <2> to <7>, the first function may be any one of a function of buying and selling the electric power in the supply and demand adjustment market, a function of buying and selling the electric power in the time - ahead market, a function of buying and selling the electric power in a plurality of markets, and an imbalance avoidance function.

[0091] <10>In the consideration calculation system according to any one of the above aspects <3> to <7>, the second function may be any one of a function of buying and selling the electric power in the spot market, a function of obtaining income by FIP, and a function of obtaining income by environmental value.

[0092] <11>A consideration calculation method according to an aspect of the present invention includes an EMS consideration calculation step of calculating a consideration for introducing an EMS into a facility including a storage battery and power generation equipment, the EMS outputs electric power trading instruction information, and the EMS consideration calculation step uses a part of the profit obtained by introducing the EMS into the facility as the consideration.

[0093] <12>A program according to an aspect of the present invention is a program for causing a computer to function as the consideration calculation system according to any one of the above aspects <1> to <10>.
