[0017] The power supply facility 3 is a power generation facility or a power storage facility including a distributed power source. The power supply facility 3 includes, for example, a storage battery, a solar power generation facility, an electric vehicle, and the like. The power demanding facility 4 is a facility that demands power in the power system and is owned by a consumer. The power demanding facility 4 includes, for example, lighting facilities and air conditioning facilities that can adjust power demand.

[0018] The evaluation device 10 is a server device that evaluates each facility (power supply facility 3 or power demand facility 4) in the power system, consumers, and the power system based on various information acquired from the power management system 2. The evaluation device 10 includes an NW (network) communication unit 11, a device storage unit 12, and a device control unit 13.

[0019] The NW communication unit 11 is a functional unit realized by a communication device such as a network adapter. The NW communication unit 11 is connected to the network NW1 and performs communication between the evaluation device 10 and the power management system 2 or the user terminal 30.

[0020] The device storage unit 12 stores various information used by the evaluation device 10.

[0021] The master information storage unit 121 stores master information of the power supply facility 3 and the power demanding facility 4 managed by the power management system 2. The master information of the power supply facility 3 includes, for example, identification information of the power supply facility 3 (facility identification information), power supply information, owner information, VPP information, BG information, and facility area information. That is, the master information storage unit 121 stores, as the master information of the power supply facility 3, for example, the identification information of the power supply facility 3, power supply information, owner information, VPP information, BG information, and facility area information in association with each other.

[0022] The power supply information also includes, for example, performance information of the power supply facility 3. The performance information of the power supply facility 3 includes, for example, the response speed, response power amount (response power amount: SOC), maximum power amount (facility capacity), rated power, controllable time period, etc. The owner information is information indicating the owner of the power supply facility 3, and is, for example, identification information of the consumer.

[0023] Furthermore, the VPP information is information indicating the VPP to which the power supply facility 3 belongs, and the BG information is information indicating the BG to which the power supply facility 3 belongs. Furthermore, the facility area information is information indicating the location, area, etc. where the power supply facility 3 is installed.

[0024] Furthermore, the master information of the power demanding facility 4 includes, for example, identification information of the power demanding facility 4, power demand information, owner information, customer group information, BG information, and facility area information. That is, the master information storage unit 121 stores, as the master information of the power demanding facility 4, for example, identification information of the power demanding facility 4 (facility identification information), power demand information, owner information, customer group information, BG information, and facility area information in association with each other.

[0025] Furthermore, the power demand information of the power demanding facility 4 includes, for example, demand fluctuation information of the power demanding facility 4 and performance information of the power demanding facility 4. The demand fluctuation information of the power demanding facility 4 includes, for example, the demand fluctuation trend of the power demanding facility 4, a prediction error, a demand fluctuation waveform, and a change rate of the demand fluctuation. Furthermore, the performance information of the power demanding facility 4 includes, for example, the power consumption (power demand) of the facility, the power demand adjustment capability, and the time period during which control is possible or not.

[0026] Moreover, the owner information is information indicating the owner of power demanding facility 4, and is, for example, identification information of the customer. Furthermore, customer group information is information indicating the customer group to which the power demanding facility 4 belongs, and BG information is information indicating the BG to which the power demanding facility 4 belongs. Furthermore, facility area information is information indicating the location, area, etc. where the power demanding facility 4 is installed.

[0027] The performance value storage unit 122 stores performance information related to the power supply and demand of the power supply facility 3 and the power demanding facility 4. The performance value storage unit 122 includes, for example, identification information of each facility of the power supply facility 3 and the power demanding facility 4, control date and time information, and control performance values ​​(supply and demand performance values).

[0028] The consumer information storage unit 123 stores various information related to each consumer managed by the power management system 2. The consumer information storage unit 123 stores, for example, identification information of each consumer, facility information owned by the consumer (facility identification information, facility type, etc.), consumer group information, BG information, etc. in association with each other. The consumer information storage unit 123 may also store information (user ID, password, etc.) used for login processing to the evaluation device 10 for each consumer.

[0029] The index information storage unit 124 stores indexes indicating the degree of contribution to stabilization of the power system, which are generated by the index generation unit 132 described below. The index information storage unit 124 stores, for example, an index for each facility, an index for each time period, an index aggregated for each owner (each consumer), an index aggregated for each location or area where the facility is located, and the like.

[0030] The output information storage unit 125 stores output information (for example, display information) generated by the output processing unit 133, which will be described later. The output information (for example, display information) includes, for example, ranking list information of consumers or facilities.

[0031] The proposal information storage unit 126 stores proposal information generated by the proposal processing unit 134, which will be described later. The proposal information is, for example, information for improving the index value and stabilizing the grid power.

[0032] The device control unit 13 is a functional unit realized by, for example, causing a processor including a CPU (Central Processing Unit) to execute a program stored in the device storage unit 12. The device control unit 13 includes an information collection unit 131, an index generation unit 132, an output processing unit 133, a proposal processing unit 134, and a reward granting unit 135.

[0033] The information collection unit 131 collects master information of the power supply facility 3, master information of the power demand facility 4, performance information, consumer information, and the like from the power management system 2 via the NW communication unit 11. The information collection unit 131 collects the above-mentioned various types of information from the power management system 2 periodically or, for example, in response to a request from the user terminal 30.

[0034] The information collection unit 131 stores the collected master information of the power supply facility 3 and the collected master information of the power demand facility 4 in the master information storage unit 121. The information collection unit 131 also stores the collected performance information in the performance value storage unit 122. The information collection unit 131 also stores the collected consumer information in the consumer information storage unit 123.

[0035] The index information storage unit 124 generates an index indicating the contribution of each facility in the power system to the stabilization of the power system based on information on the demand for power consumed by a plurality of power demand facilities 4 and information on the power supply supplied by a plurality of power supply facilities 3 including distributed power sources. Here, the index is a contribution that follows fluctuations in power supply and demand and is a score value indicating the contribution to the stabilization of the power system.

[0036] The power demand information is information stored in the master information storage unit 121, and includes at least either the equipment performance or actual demand of the power demanding equipment 4. The power supply information is information stored in the master information storage unit 121, and includes at least either the response speed, response power amount, or maximum power amount of the power supply equipment 3.

[0037] The index generating unit 132 generates an index indicating the degree of contribution based on, for example, various pieces of information stored in the master information storage unit 121, the actual value storage unit 122, and the consumer information storage unit 123. The index generating unit 132 uses, for example, each piece of information such as power demand information and power demand information as parameters, multiplies the parameters by coefficient information as weighting, and generates a score value as an index value by adding up the sum. That is, the index generating unit 132 generates a score value as an index value by using a linear combination model.

[0038] Furthermore, the index generating unit 132 generates an index value indicating the degree of contribution according to a setting condition (narrowing condition) specified by the user terminal 30. The narrowing condition is, for example, a specific unit period (e.g., one day, one week, one month, etc.), and in this case, the index generating unit 132 generates an index for each specific unit period (e.g., one day, one week, one month, etc.) according to the narrowing condition.

[0039] The narrowing-down condition is, for example, a time period. In this case, the index generating unit 132 generates an index for each time period according to the narrowing-down condition. The index generating unit 132 stores the generated index (index value) in the index information storage unit .

[0040] The output processing unit 133 outputs output information according to the index generated by the index generating unit 132. The output processing unit 133 transmits the output information to the user terminal 30 via the NW communication unit 11, and causes the output information to be displayed on the display unit 33 of the user terminal 30.

[0041] The output processing unit 133 outputs, as output information, a list (contribution ranking) in which the contributions are arranged in descending order, as shown in FIG. 2, for example. The output processing unit 133 generates display information for the contribution ranking such as the screen G1 shown in FIG. 2 in accordance with the narrowing-down conditions acquired from the user terminal 30, and displays it on the display unit 33 of the user terminal 30.

[0042] 2 is a display example showing a contribution ranking for each piece of equipment for the period: 2024 / MM / D1 00:00 to 2024 / MM / D2 00:00, and is displayed in descending order of score value, which is an index value. In this way, the output processing unit 133 outputs, as output information (display information), information in which the equipment is arranged in descending order of contribution indicated by the index.

[0043] The output processing unit 133 may generate contribution rankings by time period, day (per day), week (per week), month (per month), etc. as output information according to the filtering conditions set by the user terminal 30, and display the rankings on the display unit 33 of the user terminal 30.

[0044] Furthermore, the output processing unit 133 may generate a contribution ranking for each owner (e.g., consumer) instead of for each facility (power demand facility 4 and power supply facility 3) according to the narrowing-down conditions acquired from the user terminal 30, as output information, and display it on the display unit 33 of the user terminal 30. In this case, the output processing unit 133 aggregates the index for each consumer, and outputs the evaluation value (score value) for each consumer as output information (contribution ranking).

[0045] In addition, the output processing unit 133 may aggregate indicators, for example, for each location or area where power system equipment is located, for each VPP, or for each consumer group, depending on the filtering conditions obtained from the user terminal 30, and output output information for each location or area, for each VPP, or for each consumer group.

[0046] The output processing unit 133 stores the generated output information (display information) in the output information storage unit 125. In response to a request from the user terminal 30, the output processing unit 133 outputs the output information (display information) stored in the output information storage unit 125 to the user terminal 30 via the NW communication unit 11.

[0047] Returning to the explanation of Fig. 1, the proposal processing unit 134 makes a proposal to improve the index generated by the index generating unit 132. The proposal processing unit 134 makes a proposal to improve the index, for example, for the power demanding facility 4, based on the power supply information. The power supply information here includes, for example, the response speed, response power amount (responseable power amount: SOC), maximum power amount (facility capacity), rated power, controllable / non-controllable time period, etc. of the power supply facility 3 stored in the master information storage unit 121, as well as performance information of the power supply facility 3 stored in the performance value storage unit 122.

[0048] Based on the power supply information, the proposal processing unit 134 proposes a control and operation method for the power demanding equipment 4, addition of the power demanding equipment 4, etc., so as to improve the contribution in response to the power supply from the power supply facility 3. Specifically, the proposal processing unit 134 proposes, for example, operation settings (set temperature, light intensity, etc.) of the power demanding equipment 4 such as air conditioning equipment and lighting equipment, shifting of operation time periods, etc. The proposal processing unit 134 also proposes addition or replacement of the power demanding equipment 4 to improve the index. As a proposal for fluctuations in power consumption of the power demanding equipment, the proposal processing unit 134 may propose, for example, keeping the air conditioning equipment operating in an energy-saving mode instead of repeatedly stopping and starting it.

[0049] Furthermore, the proposal processing unit 134 makes proposals for improving the index based on the power demand information for the power supply facility 3. The power demand information here includes, for example, the trend of demand fluctuations of the power demanding facility 4 stored in the master information storage unit 121, the prediction error, the demand fluctuation waveform, the change rate of the demand fluctuation, and the like, as well as the performance information of the power demanding facility 4 stored in the performance value storage unit 122.

[0050] Based on the power demand information, the proposal processing unit 134 proposes methods for controlling and operating the power supply facility 3 and additional power supply facility 3 so as to improve the contribution of the power demand facility 4 in response to the power demand. Specifically, the proposal processing unit 134 makes proposals for controlling the charging and discharging of storage batteries and electric vehicles, for adding storage batteries and solar power generation facilities, and for replacing facilities with ones with improved performance such as capacity.

[0051] The proposal processing unit 134 stores the generated proposal for improving the index (degree of contribution) in the proposal information storage unit 126. The proposal processing unit 134 transmits a proposal to improve the generated index (contribution degree) to the user terminal 30 via the NW communication unit 11, and displays the proposal to improve the index (contribution degree) on the display unit 33 of the user terminal 30.

[0052] The reward granting unit 135 grants rewards to consumers (owners) who own power system facilities (power supply facilities 3 and power demand facilities 4) according to the indexes of the owned power system facilities. Here, the rewards are, for example, a certificate of commendation commending the consumer (owner), a certificate certifying the level or rank of the consumer (owner) (for example, gold certification, platinum certification, meister certification, etc.), etc.

[0053] The reward granting unit 135 grants a reward to the consumer (owner), for example, when the total score for the year exceeds a threshold of the certification level (or award level). The reward granting unit 135 may grant a reward to the consumer (owner) for another unit period, such as monthly, instead of annually, or when other conditions based on the indicators of the owned power system equipment are satisfied.

[0054] The user terminal 30 is a terminal device owned by a user who uses the evaluation system 1. Here, the user is, for example, a consumer who is the owner of the facilities (power supply facility 3 and power demand facility 4). The user terminal 30 is, for example, a terminal device such as a personal computer, tablet terminal, or smartphone, and is used to input various information and display information when using the evaluation system 1.

[0055] The user terminal 30 transmits, for example, input information for evaluating a power system (for example, the above-mentioned narrowing down conditions, etc.) to the evaluation device 10, receives evaluation results (for example, the above-mentioned output information) etc. from the evaluation device 10, and displays them on the display unit 33. The user terminal 30 also displays, for example, the above-mentioned proposals and the awarded rewards (certificates, certificates, etc.) received from the evaluation device 10 on the display unit 33. The user terminal 30 includes a network communication unit 31, an input unit 32, a display unit 33, a terminal storage unit 34, and a terminal control unit 35.

[0057] The input unit 32 is an input device such as a keyboard, a mouse, a touch panel, etc., and receives various information in response to user operations. The input unit 32 outputs the received various information to the terminal control unit 35.

[0058] The display unit 33 is, for example, a display device such as a liquid crystal display, etc. The display unit 33 displays display information such as the above-mentioned output information, suggestions, and rewards. The terminal storage unit 34 stores various information used by the user terminal 30.

[0059] The terminal control unit 35 is a functional unit realized by, for example, causing a processor including a CPU to execute a program stored in the terminal storage unit 34, and performs overall control of the user terminal 30.

[0084] Next, the output processing unit 133 outputs the output information to the user terminal 30 and displays it on the display unit 33 (step S203). The output processing unit 133 transmits the output information as shown on screen G1 in Fig. 2 to the user terminal 30 via the NW communication unit 11. After processing in step S203, the output processing unit 133 ends the processing.

[0085] Next, the proposal processing of the evaluation system 1 according to this embodiment will be described with reference to FIG. FIG. 8 is a diagram showing an example of the proposal process of the evaluation system 1 according to this embodiment.

[0086] 8, the user terminal 30 displays a My Page screen (step S301). The terminal control unit 35 of the user terminal 30 displays a My Page screen, such as screen G4 shown in FIG.

[0087] Next, the terminal control unit 35 requests the evaluation device 10 for a proposal to improve the score in response to the operation of the input unit 32 on a My Page screen such as screen G4 shown in Fig. 5 (step S302). When the button BT6 for "Proposal to improve the score" is pressed (selected) by the input unit 32 on the My Page screen such as screen G4 shown in Fig. 5, the terminal control unit 35 transmits a proposal request for a proposal to improve the score to the evaluation device 10 via the NW communication unit 31.

[0088] Next, the proposal processing unit 134 of the evaluation device 10 generates proposal information according to the consumer based on the index (score) indicating the degree of contribution (step S303). The proposal processing unit 134 generates proposal information such as a control and operation method for the power demanding facility 4 and additional proposals for the power demanding facility 4 based on, for example, the power supply information so that the degree of contribution increases in response to the power supply from the power supply facility 3. Specifically, the proposal processing unit 134 generates proposal information such as, for example, operation settings (set temperature, light intensity, etc.) of the power demanding facility 4 such as air conditioning equipment and lighting equipment, shifting of operation time periods, etc.

[0089] Furthermore, the proposal processing unit 134 generates proposal information such as a control and operation method for the power supply facility 3 and a proposal for adding the power supply facility 3, based on the power demand information, for example, so as to improve the contribution in response to the power demand of the power demanding facility 4.

[0093] As shown in FIG. 9, the reward granting unit 135 of the evaluation device 10 first determines whether or not the reward conditions based on the indexes are satisfied (step S401). The reward granting unit 135 determines, for example, for each consumer, whether or not the reward conditions based on the indexes are satisfied. The reward granting unit 135 determines whether or not the reward conditions are satisfied based, for example, on whether or not the total score value for the year exceeds the threshold of the certification level (or award level). For example, if the reward conditions based on the indexes are satisfied (step S401: YES), the reward granting unit 135 proceeds to step S402. On the other hand, for example, if the reward conditions based on the indexes are not satisfied (step S401: NO), the reward granting unit 135 returns the process to step S401.

[0094] In step S402, the reward granting unit 135 grants a reward to the consumer according to the index. The reward granting unit 135 grants, for example, a certificate of commendation to commend the consumer (owner), a certificate of recognition of the level or rank of the consumer (owner) (for example, gold certification, platinum certification, meister certification, etc.), etc.

[0095] Next, the reward granting unit 135 outputs information indicating the reward to the user terminal 30 and causes the display unit 33 to display the information indicating the reward (step S403). The reward granting unit 135 transmits the information indicating the reward to the user terminal 30 via the NW communication unit 11 and causes the display unit 33 to display the information indicating the reward. After the processing of step S305, the reward granting unit 135 ends the reward granting process.
