Description

  The present invention relates to a power management device, a terminal device, a power management method, and a power management program.

  2. Description of the Related Art Conventionally, a system for managing power consumption in a power demand facility has been developed so that power consumption in a power demand facility such as a general home and an office is suppressed when the power supply and demand is tight.

  For example, Patent Document 1 (Japanese Patent Laid-Open No. 2012-205358) discloses the following technique. That is, the power management system includes a holding unit that holds a participant list related to a community including a plurality of registered participants, a determination unit that determines whether or not to execute power reduction control, and execution of power reduction control. When the determination unit determines that it is necessary, a selection unit that selects one or more target persons to be subjected to power reduction control from a plurality of participants included in the participant list, and a selection unit With respect to the selected target person, the control part which performs power reduction control, and the provision part which provides the privilege based on reduced power with respect to the target person by which power reduction control was performed are provided.

  Further, for the purpose of power saving, an energy management system xEMS (Energy Management System) has been introduced into a power demand facility such as a home or a building.

  xEMS is a system for monitoring power consumption in a power demand facility and managing power consumption in the power demand facility by managing the operating state of equipment or equipment in the power demand facility. The xEMS is a Home Energy Management System (HEMS) when it is for a home, and a BEMS (Building Energy Management System) when it is for a building.

  xEMS realizes suppression of power demand by, for example, cooperating with a VPP (Virtual Power Plant) operator, that is, an operator called an aggregator. The aggregator provides an energy management support service to a power demand facility in which xEMS is introduced.

  In addition, for example, a technique for preventing a reverse power flow (power sale) to a system of generated power by a power generation device in a power demand facility such as solar power generation provided in a general household has been developed.

  For example, Patent Document 3 (Japanese Patent Laid-Open No. 2013-172495) discloses a power storage type power generation system that can use generated power without waste. The power storage type power generation system is connected to an external system, generates a power by receiving natural energy, and stores a power generated by the power generation unit and power from the system, and is connected to the power generation unit in a DC connection. And a control unit that controls power generation of the power generation unit and charge / discharge of the power storage unit. When the generated power is flowing backward toward the grid, the control unit stops the reverse flow of the generated power based on the comparison between the grid voltage and a predetermined threshold voltage, or generates power that flows backward. The power is reduced and the generated power is charged to the storage battery.

  Further, for example, in Patent Document 4 (Japanese Patent Laid-Open No. 11-299110), when a private power generator and a commercial power source are operating in parallel, a reverse power flow caused by a sudden load fluctuation is applied to the generator or engine. An electric power reverse flow preventing device that prevents the load without imposing a large burden is disclosed. In the reverse power flow prevention device, the engine governor adjusts the amount of fuel supplied to the generator driving engine of the private power generation facility according to the speed. The speed control means controls the fuel supply amount of the engine governor so as to adjust the speed of the generator driving engine according to the predicted value of load fluctuation. The received power detection means detects power received from a commercial power source. Then, the high speed control means responds to the output from the received power detection means, and when the reduced state of the received power with respect to the preset minimum received power value continues so as to satisfy a predetermined condition for the received power reduction time, The control over the engine governor by the control means is stopped, and the engine governor is controlled within the allowable reverse power flow time so that the fuel supply amount corresponds to the preset reduction of the received power amount, and the received power is predetermined. When the recovery condition is satisfied, the control to the engine governor by the speed control means is recovered.

  For example, transmission / distribution operators and power retailers can easily adjust the overall power demand over a wide range by introducing xEMS in many power demand facilities.

  For example, a power transmission / distribution company and a power retailer make a power-saving request in advance to the aggregator when power supply and demand are expected to be tight. Then, the aggregator makes a power saving request to a consumer of the power demand facility.

  Also, for example, if the power supply / distribution company is expected to exceed the demand, the power transmission / distribution company supplies power to the grid with respect to the renewable energy company and consumers who own the power generation equipment. Request suppression.

<First Embodiment>
[Configuration and basic operation]
FIG. 1 is a diagram showing a configuration of a power management system according to the first embodiment of the present invention.

  Referring to FIG. 1, a power management system 301 includes a power management server (power management device) 101, a system side server 121, a terminal device 171, and three customer devices 202.

  In FIG. 1, three customer devices 202 are representatively shown, but a larger or smaller number of customer devices 202 may be provided. In addition, two loads 205 are representatively shown corresponding to the consumer device 202, but a larger or smaller number of loads 205 may be provided corresponding to the consumer device 202.

  In the power management system 301, for example, when the supply and demand of power is tight or when there is a possibility that the supply and demand of power may be tight, each customer issues a demand response (DR: Demand Response) for suppressing power consumption. Is possible.

  The grid-side server 121 in the power management system 301 is operated by a power transmission / distribution provider or a power retailer on the power grid side, and transmits suppression information S1 indicating a request for suppression of power consumption to the power management server 101. The suppression information S1 includes, for example, request power R1 indicating the start timing of the request period for power consumption suppression (hereinafter also referred to as DR period), the length of the DR period, and the amount of power consumption suppression. Note that the suppression information S1 may include the end timing of the DR period instead of the length of the DR period.

  The consumer device 202 is used in a power demand facility such as a building, a factory, or a general household that receives power supply from an electric power company. One consumer device 202 may be provided for each power demand facility, or a plurality of customer devices 202 may be provided for each power demand facility. The power company is, for example, a power generation company or a power retailer.

  The consumer device 202 can control one or a plurality of loads 205 in the power demand facility. The load 205 is a secondary battery type electric vehicle and a plug-in hybrid car using a secondary battery as an energy source, and an electric device such as a lighting, a television, and an air conditioner.

  More specifically, the consumer device 202 is a device used in xEMS for reducing power consumption by controlling the operation of electric equipment, and is introduced by, for example, an aggregator.

  The power management server 101 is operated by, for example, an aggregator, and manages power consumption in one or more power demanding facilities by communicating with one or more consumer devices 202. The power management server 101 is often installed, for example, at a location remote from the power demand facility where the customer apparatus 202 is provided.

  The wholesale power exchange server 111 provides, for example, a power trading market for each contract such as a one-hour contract and a four-hour contract. Details of the operation of the wholesale power exchange server 111 will be described later.

  With reference to FIG. 2, the power management server 101 includes a communication unit (notification unit) 21, a processing unit (creation unit) 22, and a storage unit 23.

  The communication unit 21 in the power management server 101 can transmit / receive information to / from other devices. In this example, the communication unit 21 can transmit / receive information to / from the wholesale power exchange server 111, the grid-side server 121, the terminal device 171, and the customer device 202.

  The storage unit 23 holds management information, performance aggregation information, DR possible amount information, and various types of registration information. The DR possible amount information and various registration information will be described later.

  Here, the management information includes, for example, a customer ID of each customer managed by the aggregator, a contract content corresponding to the customer ID, a schedule, and a device ID of the customer device 202. For example, the customer ID belongs to a group corresponding to the contract content. Each of these contracts has an incentive for saving electricity. A schedule shows the period when a consumer cannot participate in DR, for example.

  The result aggregation information indicates, for example, the DR results of each customer. Specifically, the performance aggregation information includes the DR period and requested power R1 requested from the grid-side server 121 for each customer ID, and the actual value of power saved during the period.

  For example, the processing unit 22 periodically predicts the DR possible amount of each customer managed by its own power management server 101.

Each of the programs of the plurality of apparatuses can be installed from the outside. The programs of the plurality of apparatuses are distributed while being stored in a recording medium.

  FIG. 5 is a diagram illustrating an example of a sequence of each process before DR execution in the power management system according to the first embodiment of the present invention.

  With reference to FIG. 5, first, the power management server 101 periodically predicts the DR possible amount (step S102).

  Next, the power management server 101 performs the recommendation process RP1 (step S104).

[Recommendation Processing RP1]
FIG. 6 is a diagram showing an example of a recommendation processing sequence in the power management system according to the first embodiment of the present invention. FIG. 6 shows details of the operation in step S104 of FIG.

  With reference to FIGS. 2 to 4 and 6, it is assumed that the display control unit 62 in the terminal device 171 performs control to display the screen Sc <b> 1 shown in FIG. 4 on the display device.

  First, the terminal device 171 performs input reception processing (step S702).

  More specifically, for example, the operator refers to the screen Sc1 and performs an operation on the terminal device 171 to input at least a “control period”. Here, the “control period” is, for example, a period during which the aggregator participates in DR, and can be specified in units of 30 minutes.

  Further, the operator can designate “control amount” and “control condition” as options. Here, the “control amount” indicates a target of power saving power in the “control period”.

  “Control condition” indicates a condition of a request destination, that is, a customer. Specifically, the “control condition” includes the specification of the number of consumers to be extracted, the specification of the region where the power demand facility of the consumers to be extracted is located, and the method of extracting customers such as turn number and priority order. The designation and presence / absence of participation of the customer in the past period.

  When the input of each item is completed, the operator performs an operation of selecting an “execute” button.

  The receiving unit 64 in the terminal device 171 receives an operation of the operator, creates operation information indicating the received operation, and outputs the operation information to the notification unit 65.

  Next, when the notification unit 65 receives the operation information from the reception unit 64, the notification unit 65 transmits the received operation information to the power management server 101 (step S704).

  Next, the power management server 101 performs candidate information creation processing (step S706).

  The processing unit 22 in the power management server 101 creates a plurality of candidate information indicating a request destination and details of power consumption suppression.

  More specifically, the processing unit 22 creates candidate information prior to reception of the suppression information S1, for example.

  For example, the processing unit 22 creates a plurality of pieces of candidate information based on the content of power consumption suppression and the condition information indicating the request destination condition.

  Specifically, the processing unit 22 creates candidate information based on, for example, a control period and a control amount indicating the period and amount of power consumption suppression, condition information, and a schedule included in a request destination schedule, that is, management information, for example. To do.

  In addition, for example, the processing unit 22 creates candidate information such that one or more request destinations indicated by the candidate information are different between at least two pieces of candidate information.

  Specifically, when receiving the operation information from the terminal device 171 via the communication unit 21, the processing unit 22 recognizes the control period and the control amount as the content of power consumption suppression based on the received operation information. For example, when the operator does not designate “control amount”, the processing unit 22 uses the DR possible amount in the control period based on the DR possible amount information as the control amount.

  Further, the processing unit 22 acquires “control condition” designated by the operator from the operation information as condition information, and recognizes the content of the acquired condition information. For example, when the operator does not designate a “control condition”, the processing unit 22 uses at least one of the above-described “control conditions” as default condition information.

  The processing unit 22 creates a plurality of pieces of candidate information that are different from each other based on the management information and the result aggregation information in the storage unit 23, the control period, the control amount, and the condition information.

  Specifically, for example, the processing unit 22 determines a request destination to be included in the candidate information based on the content of suppression of power consumption and the condition information.

  More specifically, for example, the processing unit 22 provisionally determines a request destination based on the content of power consumption suppression, and based on the condition information, selects a request destination to be included in the candidate information from the provisionally determined request destination. decide.

  Specifically, the processing unit 22 creates input data including the DR performance, schedule, control period, and control amount of each consumer using, for example, management information, performance aggregation information, control period, and control amount. . Further, the processing unit 22 creates control condition data including the contents of the condition information.

  For example, the processing unit 22 has an optimization engine, and by inputting the created input data and control condition data to the optimization engine, the customer ID of each customer that satisfies the input data is temporarily stored. Extract.

  The processing unit 22 fully extracts the customer ID of each customer that satisfies the condition indicated by the condition information from the customer IDs of the temporarily extracted customers.

  Specifically, the processing unit 22, for example, satisfies 70 customer IDs, 100 customer IDs, and 150 customer IDs that satisfy the input data. A customer ID of an arbitrary number of customers such as a customer ID is temporarily extracted.

  Then, for example, when the number of consumers to be extracted is specified as 100 as the condition indicated by the condition information, the processing unit 22 has 100 customers in the set of temporarily extracted customer IDs. The customer ID is extracted.

  Note that the processing unit 22 does not temporarily determine the request destination, and finally extracts the customer ID of each customer that satisfies the input data and the control condition based on the content of the suppression of power consumption and the condition information. May be. This determination method is suitable, for example, when the area where the power demand facility of the consumer to be extracted is located is specified as the condition indicated by the condition information.

  Further, the processing unit 22 may determine the request destination based on the content of power consumption suppression without using the condition information. Specifically, the processing unit 22 may extract the customer ID of each customer that satisfies the control period and the control amount based on the turn number, or may extract it randomly.

  The processing unit 22 calculates the power saving power allocated to each extracted consumer, the total of each allocated power saving power, that is, the expected power saving power, and the total of the incentives to be paid to each consumer, that is, the cost.

  Then, the processing unit 22 creates, for example, three pieces of candidate information including the extracted customer ID and the calculated power saving power, power saving power expected value, and cost, and adds indexes to the created three candidate information.

  Next, the processing unit 22 creates processing result information including three candidate information and control amounts, and transmits the created processing result information to the terminal device 171 via the communication unit 21. The acquisition unit 61 in the terminal device 171 acquires a plurality of candidate information from the power management server 101. More specifically, the acquisition unit 61 receives processing result information from the power management server 101 (step S708).

  Next, the terminal device 171 performs display processing (step S710). Specifically, the acquisition unit 61 in the terminal device 171 outputs the received processing result information to the display control unit 62.

  FIG. 7 is a diagram illustrating an example of a screen created by the terminal device in the power management system according to the first embodiment of the present invention. FIG. 7 shows a DR plan candidate screen.

  Referring to FIG. 7, when receiving the processing result information from acquisition unit 61, display control unit 62 performs control to display screen Sc2 shown in FIG. 7 on the display device based on the received processing result information.

  In the screen Sc2, the contents of the three pieces of candidate information are displayed in the index order. “Achievment rate expected (%)” is a value obtained by dividing the expected value of power saving power by the control amount in percentage. “Estimated amount of power reduction (kW)” and “Total paid incentive (yen)” are an expected value of power saving and a cost, respectively. “Number of selected resources” is the number of customer IDs extracted by the power management server 101.

  Further, by performing an operation for selecting the “detail” button on the terminal device 171, it is possible to display details about the corresponding candidate on the display device.

  Next, the terminal device 171 performs input reception processing (step S712).

  More specifically, for example, the operator refers to the screen Sc2, determines a candidate that suits his preference, in this example, the first candidate, and “selects this candidate” corresponding to the candidate whose index is 1. An operation for selecting a button is performed on the terminal device 171.

  The accepting unit 64 accepts an operator's operation, creates operation information indicating the accepted operation, and outputs the created operation information to the notification unit 65.

  The notification unit 65 notifies the power management server 101 of candidate information selected by the operator, for example, from among the candidate information acquired by the acquisition unit 61. Specifically, when receiving the operation information from the receiving unit 64, the notification unit 65 transmits the received operation information to the power management server 101 (step S714).

  Next, the power management server 101 performs market registration information creation processing (step S716). More specifically, when the processing unit 22 in the power management server 101 receives operation information from the terminal device 171 via the communication unit 21, based on the received operation information, candidate information with an index of 1 is selected by the operator.

More specifically, the processing unit 22 in the power management server 101 stores the created market registration information in the storage unit 23, that is, registers it.

  Next, a successful bid process is performed among the grid-side server 121, the wholesale power exchange server 111, and the power management server 101 (step S108).

  More specifically, based on the market registration information, the power management server 101 uses its own ID and control period, and the cost and power saving power expected value for the candidate information selected by the operator as a product, the wholesale power exchange server 111. Register with.

  The system server 121 purchases a product from the products registered in the wholesale power exchange server 111 so as to satisfy the DR plan, that is, makes a successful bid.

  Next, the system side server 121 transmits the suppression information S1 to the power management server 101 (step S110). More specifically, the system side server 121 transmits, for example, the suppression information S1 including the DR period and the requested power R1 to the power management server 101 in accordance with the content of the successful bid product. The system-side server 121 may transmit suppression information S1 that does not conform to the content of the successful bid product to the power management server 101.

  Next, the power management server 101 performs a suppression information registration process (step S112). More specifically, the communication unit 21 in the power management server 101 receives the suppression information S1 from, for example, another device, specifically, the system side server 121, and outputs the received suppression information S1 to the processing unit 22.

  When receiving the suppression information S <b> 1 from the communication unit 21, the processing unit 22 stores the received suppression information S <b> 1 in the storage unit 23.

  Next, the processing unit 22 performs a recommendation process RP2 (step S114).

[Recommendation Processing RP2]
FIG. 8 is a diagram illustrating an example of a recommendation processing sequence in the power management system according to the first embodiment of the present invention. FIG. 8 shows details of the operation in step S114 of FIG.

  Referring to FIG. 2, FIG. 3, FIG. 8, and FIG. 9, when the DR is not urgent, the processing unit 22 specifically, the time until the start timing of the DR period included in the suppression information S1 is a predetermined value. If it is equal to or less than Th1 (NO in step S802), the suppression information S1 and the processing result information are transmitted to the terminal device 171 via the communication unit 21 (step S804).

  Next, the terminal device 171 performs display processing (step S806). More specifically, when receiving the suppression information S1 and the processing result information from the power management server 101, the acquisition unit 61 in the terminal device 171 outputs the received suppression information S1 and the processing result information to the display control unit 62.

  When receiving the suppression information S1 and the processing result information from the acquisition unit 61, the display control unit 62 performs control for displaying the screen Sc3 illustrated in FIG. 9 on the display device based on the received suppression information S1 and the processing result information.

  In the screen Sc3, in the graph Gr1, the vertical axis indicates power, and the horizontal axis indicates time. In this example, in the graph Gr1, a rectangle indicating a control request of 200 kW from 10:00 to 12:00 based on the DR period and the requested power R1 included in the suppression information S1 is drawn.

  Further, the three candidates in the “DR plan candidate” are the same as the three candidates shown in FIG. 7, for example.

  Further, by performing an operation for selecting the “recreate” button on the terminal device 171, it is possible to recreate a plurality of candidates. In this case, the power management server 101 performs the recommendation process RP1 to recreate a plurality of pieces of candidate information.

  Next, the terminal device 171 performs input reception processing (step S808).

  More specifically, for example, when the operator refers to the screen Sc3 and does not change the candidate selected on the screen Sc2 shown in FIG. 7, the operator performs an operation of selecting the “select this candidate” button corresponding to No. 1 To the device 171.

  On the other hand, for example, the operator performs an operation of selecting the “select this candidate” button corresponding to No. 2 or No. 3 on the terminal device 171 to reselect the No. 2 or No. 3 candidate. Is possible.

  The accepting unit 64 accepts an operator's operation, creates operation information indicating the accepted operation, and outputs the created operation information to the notification unit 65.

  Upon receiving the operation information from the reception unit 64, the notification unit 65 transmits the received operation information to the power management server 101 (step S810).

  Next, the power management server 101 performs request information creation processing (step S812). More specifically, the processing unit 22 in the power management server 101 creates request information having contents based on candidate information selected from the three candidate information created by itself.

  Here, since the DR is not urgent, the processing unit 22 receives the operation information from the terminal device 171 via the communication unit 21 and creates request information based on the received operation information.

  More specifically, the processing unit 22 recognizes that the candidate information with the index of 1 is selected by the operator based on the operation information. From the candidate information with the index of 1, each customer ID and each demand The power saving power allocated to the consumer indicated by the house ID is acquired.

  And the process part 22 acquires apparatus ID corresponding to each acquired customer ID from management information as a destination of request information, and contains a corresponding destination, DR period, and corresponding power-saving power for every apparatus ID. Create request information.

  On the other hand, if it is an emergency DR (YES in step S802), the processing unit 22 selects candidate information from among the three candidate information created by itself according to the specified criteria, and the content based on the selected candidate information Create request information. Here, the designated criteria are, for example, “estimated achievement rate (%)”, “estimated power reduction amount (kW)”, “total payment reward (yen)” and “selected resources” shown in FIG. It is a criterion using any one of “number of”.

  The processing unit 22 outputs the created request information to the communication unit 21.

  Referring to FIG. 5 again, next, communication unit 21 notifies the request destination of request information having contents based on the candidate information selected from the candidate information created by processing unit 22 (step S116). .

  More specifically, when receiving the request information from the processing unit 22, the communication unit 21 transmits the received request information to the customer device 202 indicated by the destination included in the request information.

  Next, when each customer apparatus 202 receives request information from the power management server 101, it performs a request information registration process for registering the received request information (step S118).

  Next, each consumer device 202 transmits response information indicating whether or not to permit the contents of the request information to the power management server 101 (step S120).

  Next, each consumer device 202 periodically transmits performance value information indicating the performance of its own DR to the power management server 101 (step S122).

  Next, for example, after the request information is notified by the communication unit 21, the processing unit 22 in the power management server 101 determines whether or not a request for suppressing power consumption can be achieved (step S124).

  More specifically, the processing unit 22 receives response information and actual value information from each consumer device 202 via the communication unit 21, and based on the response information, actual value information, and suppression information S1, the system side server 121. It is determined whether adjustment is necessary to satisfy the DR request from

  When determining that the adjustment is necessary (YES in step S124), the processing unit 22 creates new candidate information (step S128). Specifically, the processing unit 22 performs a recommendation process RP2.

  On the other hand, when determining that the adjustment is not necessary (NO in step S124), the processing unit 22 transmits a permission response signal indicating permission of the suppression information S1 to the system side server 121 via the communication unit 21 (step S124). S126).

  The order of steps S120 and S122 is not limited to the above, and the order may be changed.

  FIG. 10 is a diagram illustrating an example of a sequence of processes during and after DR execution in the power management system according to the first embodiment of the present invention.

  Referring to FIG. 10, each customer device 202 assumes a situation in which DR is being executed according to the request information received from power management server 101.

  First, each customer device 202 periodically transmits actual value information to the power management server 101 during DR execution (step S202).

  Next, the power management server 101 performs a monitoring process (step S204). More specifically, the processing unit 22 in the power management server 101 receives the actual value information from each customer device 202 via the communication unit 21, and based on the actual value information and the suppression information S1, the currently executing DR The degree of achievement is monitored (step S204).

  Next, when the processing unit 22 determines that the achievement level does not reach the target (YES in step S206), the processing unit 22 performs a recommendation process RP3 (step S208). Here, since DR is being executed, the processing unit 22 performs the recommendation process RP3 without making an inquiry to the operator, for example.

  More specifically, the processing unit 22 creates, for example, three candidate information. Specifically, for example, the processing unit 22 creates candidate information in which the number of customer IDs included in the candidate information created before the start of DR (hereinafter also referred to as pre-start candidate information) is increased or decreased, Create candidate information including customer IDs not included in the candidate information before start in the candidate information before start, or create candidate information including customer IDs of consumers belonging to other groups in the candidate information before start Or

  Then, for example, the processing unit 22 selects candidate information from among the three candidate information created by the processing unit 22 in accordance with a designated standard.

  The processing unit 22 creates request information for each customer whose DR content is to be changed based on the selected candidate information and management information, and outputs the created request information to the communication unit 21.

  Next, when receiving the request information from the processing unit 22, the communication unit 21 transmits the received request information to the consumer device 202 indicated by the destination included in the request information (step S210).

  Next, when each customer device 202 whose DR content is to be changed receives request information from the power management server 101, it performs a request information registration process for registering the received request information (step S212).

  Next, each customer apparatus 202 subject to change of the contents of DR executes DR according to the request information (step S214).

  On the other hand, if the processing unit 22 determines that the achievement level has reached the target (NO in step S206), the processing unit 22 does not perform the recommendation process RP3.

  The processes in steps S204 to S214 are repeated, for example, periodically until DR ends.

  Next, each customer apparatus 202 periodically transmits the actual value information to the power management server 101 after the DR is executed (step S216).

  Next, the power management server 101 performs aggregation processing. More specifically, the processing unit 22 in the power management server 101 receives the actual value information from each consumer device 202 via the communication unit 21, and participates in the DR based on the actual value information and the suppression information S1. The results of power saving in the customer's DR period are tabulated (step S218).

  Next, the power management server 101 performs an update process. More specifically, the processing unit 22 updates the result aggregation information in the storage unit 23 based on the aggregation result (step S220).

  Next, the processing unit 22 transmits actual value information including the total value of the power saving power in the DR period of each customer who participated in the DR to the system side server 121 via the communication unit 21 (step S222).

  Next, when the system side server 121 receives the actual value information from the power management server 101, the system side server 121 performs an actual value registration process for registering the content of the received actual value information (step S224).

  In the power management server according to the first embodiment of the present invention, the processing unit 22 is configured to create a plurality of candidate information indicating both the request destination and the content of suppression of power consumption. It is not limited to. The processing unit 22 may be configured to create a plurality of candidate information indicating either the request destination of power consumption suppression or the content.

  By the way, for example, power transmission / distribution operators and power retailers can easily adjust the overall power demand in a wide range by introducing xEMS in many power demand facilities.

  For example, a power transmission / distribution company and a power retailer make a power-saving request in advance to the aggregator when power supply and demand are expected to be tight. Then, the aggregator makes a power saving request to a consumer of the power demand facility.

  Also, for example, if the power supply / distribution company is expected to exceed the demand, the power transmission / distribution company supplies power to the grid with respect to the renewable energy company and consumers who own the power generation equipment. Request suppression.

  However, if the content of the request to the renewable energy business operator and the customer is not appropriate, it is not preferable because the power supply / demand is tight or the supply of power exceeds the demand, and the power supply / demand balance in the system is lost.

  On the other hand, the power management server according to the first embodiment of the present invention is a power management device that manages power consumption. The processing unit 22 creates a plurality of candidate information indicating at least one of the request destination and the content of the power consumption suppression.

  With such a configuration, for example, it is possible to set conditions such as the contents of suppression and the results, area, and priority of the client, so that more appropriate candidate information can be recommended.

  Further, in the power management server according to the first embodiment of the present invention, the processing unit 22 creates candidate information based on the request destination schedule.

  With such a configuration, for example, it is possible to create candidate information in which a period inconvenient for the client is excluded, so that it is possible to increase the possibility that power consumption or power supply to the system will be suppressed as scheduled. Can do.

  In the power management server according to the first embodiment of the present invention, the processing unit 22 creates candidate information based on at least one of the period and the amount of power consumption suppression.

  With such a configuration, candidate information reflecting the target can be created, so that it is possible to increase the possibility that the power consumption will be suppressed according to the target.

  In addition, the power management server according to the first embodiment of the present invention receives suppression information S1 indicating a request regarding suppression of power consumption from another device. Then, the processing unit 22 creates candidate information prior to receiving the suppression information S1.

  With such a configuration, for example, the executable content based on the candidate information selected in the power management server 101 can be notified to another device, so that the feasibility of the content of the suppression information S1 can be enhanced. . Thereby, the content of suppression information S1 can be performed smoothly.

  In addition, the power management server according to the first embodiment of the present invention receives suppression information S1 indicating a request regarding suppression of power consumption from another device. Then, after the request information is notified by the communication unit 21, the processing unit 22 creates new candidate information when determining that the request cannot be achieved.

  With such a configuration, when the suppression is not performed according to the content of the suppression information S1, the request destination and the request amount can be added or reduced, so that the execution possibility of the content of the suppression information S1 can be reduced. Can be increased.

  Further, in the terminal device according to the first embodiment of the present invention, the acquisition unit 61 uses the power management server that manages power consumption as candidate information indicating a request destination of power consumption suppression and / or content. A plurality are acquired from 101. The notification unit 65 notifies the power management server 101 of candidate information selected from the candidate information acquired by the acquisition unit 61.

  With such a configuration, for example, various candidate information acquired from the power management server 101 can be recommended to the user, so that the user can select candidate information that suits the taste. Then, with the configuration in which the candidate information selected by the user is notified to the power management server 101, for example, the power management server 101 can notify the request destination of request information with more appropriate content based on the selected candidate information. As a result, power consumption can be appropriately suppressed. Therefore, it is possible to realize a good balance between power supply and demand.

For example, the customer ID belongs to a group corresponding to the contract content. Each of these contracts has an incentive for supply restraint power. A schedule shows the period when a consumer cannot participate in PV output control, for example.

  The track record information indicates, for example, track record of PV output suppression of each consumer. Specifically, the performance aggregation information includes the PV suppression period and the requested power R2 requested from the transmission / distribution company server 141 for each customer ID, and the actual value of the power suppressed during the period.

[Operation]
FIG. 13: is a figure which shows an example of the sequence of each process before PV output suppression execution in the power management system which concerns on the 2nd Embodiment of this invention.

  With reference to FIG. 13, the retailer server 151 first periodically notifies the power transmission and distribution company server 141 of the demand plan value for each predetermined period (step S302).

  Next, the renewable energy company server 131 periodically notifies the transmission / distribution company server 141 of the predicted power generation amount for each predetermined period, for example (step S304).

  Next, the power transmission / distribution company server 141 determines whether or not it is necessary to suppress the power supply to the grid based on the notification contents notified from the retail company server 151 and the renewable energy server 131. Processing is performed (step S306). Here, the power transmission / distribution company server 141 determines that it is necessary to suppress power supply to the grid.

  Next, the power transmission and distribution company server 141 transmits the suppression information S2 to the power management server 102 (step S308).

  Next, the power transmission / distribution company server 141 transmits the suppression information S3 to the renewable energy company server 131 (step S310).

  Next, when the renewable energy company server 131 receives the suppression information S3 from the power transmission and distribution company server 141, the renewable energy company server 131 performs a suppression information registration process for registering the received suppression information S3 (step S312).

  Next, the power management server 102 performs a suppression information registration process (step S314). More specifically, for example, the communication unit 21 in the power management server 102 receives the suppression information S2 from another device, specifically, the power transmission and distribution company server 141, and outputs the received suppression information S2 to the processing unit 32. To do.

  When receiving the suppression information S2 from the communication unit 21, the processing unit 32 stores the received suppression information S2 in the storage unit 23.

  Next, the consumer device 202 periodically transmits solar radiation amount information indicating the current and future solar radiation amounts in its own power demand facility to the power management server 102 (step S316).

  Next, the power management server 102 performs a power generation amount prediction process (step S318). More specifically, the processing unit 32 in the power management server 102 predicts the power generation amount in the PV suppression period included in the suppression information S2 based on the solar radiation amount information received from the consumer device 202 via the communication unit 21.

  Next, for example, the processing unit 32 determines whether or not to respond to the request indicated by the suppression information S2 based on the predicted power generation amount (step S320).

  More specifically, the processing unit 32 determines whether suppression of the requested power R2 can be achieved in the PV suppression period using the predicted power generation amount. Specifically, when the amount of solar radiation is small and the predicted power generation amount is small, the processing unit 32 determines that the request power R2 cannot be suppressed, and determines that the request indicated by the suppression information S2 is not satisfied. Further, when the predicted power generation amount is large because the amount of solar radiation is large, the processing unit 32 determines that suppression of the requested power R2 can be achieved, and determines that the request indicated by the suppression information S2 is satisfied.

  When the processing unit 32 determines that the request indicated by the suppression information S2 is not satisfied (NO in step S320), the processing unit 32 transmits a non-permission response signal to the power transmission and distribution company server 141 via the communication unit 21 (step S322).

  Next, when receiving the non-license response signal from the power management server 102, the transmission / distribution company server 141 performs a recording process for recording the received non-license response signal (step S324).

  On the other hand, if the processing unit 32 determines that the request indicated by the suppression information S2 is satisfied (YES in step S320), the processing unit 32 performs a recommendation process RP4 (step S326).

[Recommendation Processing RP4]
FIG. 14 is a diagram showing an example of a recommendation process sequence in the power management system according to the second embodiment of the present invention. FIG. 14 shows details of the operation in step S326 of FIG.

  Referring to FIGS. 3, 12, and 14, first, power management server 102 performs candidate information creation processing (step S900).

  More specifically, the processing unit 32 in the power management server 102 creates a plurality of candidate information indicating a request destination and details of suppression of power supply to the system.

  The processing unit 32 creates a plurality of candidate information based on, for example, the content of suppression of power supply to the grid and the condition information indicating the request destination condition.

  Here, the condition information indicates, for example, the condition of the request destination, here, the customer, and is registered in advance by the operator. Specifically, for example, the condition of the consumers is the specification of the number of consumers to be extracted, the specification of the region where the power demand facility of the consumers to be extracted is located, the extraction of consumers such as the turn number and the priority order, etc. It is the designation | designated of a method, the presence or absence of participation of the consumer's PV output suppression in the past period, etc.

  Specifically, the processing unit 32 is based on, for example, a PV suppression period and requested power R2 that indicate the period and amount of suppression of power supply to the system, condition information, and a schedule included in a request destination schedule, that is, management information, respectively. To create candidate information.

  In addition, for example, the processing unit 32 creates candidate information so that one or more request destinations indicated by the candidate information are different between at least two pieces of candidate information.

  The processing unit 32 creates a plurality of pieces of candidate information that are different from each other based on the management information and the result aggregation information in the storage unit 23, the PV suppression period, the requested power R2, and the condition information.

  Specifically, the processing unit 32 determines a request destination to be included in the candidate information based on, for example, the content of suppression of power supply to the grid and the condition information.

  Specifically, the processing unit 32 uses, for example, management information, performance aggregation information, PV suppression period, and requested power R2 to obtain the PV output suppression results, schedule, PV suppression period, and requested power R2 of each consumer. Create input data including. In addition, the processing unit 32 creates control condition data including the contents of the condition information.

  For example, the processing unit 32 inputs the created input data and control condition data to the optimization engine, thereby extracting the customer ID of each customer that satisfies the input data and the control condition data.

  In addition, the process part 32 may determine a request destination based on the content of suppression of the electric power supply to a system | strain, without using condition information. Specifically, the processing unit 32 may extract the customer ID of each customer that satisfies the PV suppression period and the requested power R2 by the turn number, or may extract it randomly.

  The processing unit 32 calculates the supply suppression power allocated to each extracted consumer, the total of all allocated supply suppression power, that is, the expected supply suppression power, and the total of incentives to be paid to each extracted consumer, that is, the cost.

  Then, the processing unit 32 creates, for example, three pieces of candidate information including the extracted customer ID and the calculated supply suppression power, supply suppression power expected value, and cost, and attaches indexes to the three candidate information created.

  Next, when the PV output suppression is not urgent, specifically, when the time until the start timing of the PV suppression period included in the suppression information S2 is equal to or less than the predetermined value Th2 (NO in step S902) ), The following processing is performed.

  That is, the processing unit 32 transmits each candidate information and the suppression information S2 to the terminal device 171 via the communication unit 21. The acquisition unit 61 in the terminal device 171 receives the candidate information and the suppression information S2 from the power management server 102 (step S904).

  FIG. 15 is a diagram illustrating an example of a screen created by the terminal device in the power management system according to the second embodiment of the present invention. FIG. 15 shows an event screen.

  Referring to FIG. 15, next, terminal apparatus 171 performs display processing (step S906). More specifically, the acquisition unit 61 in the terminal device 171 outputs the received candidate information and suppression information S2 to the display control unit 62.

  Upon receiving each candidate information and suppression information S2 from the acquisition unit 61, the display control unit 62 performs control to display the screen Sc4 illustrated in FIG. 15 on the display device based on the received candidate information and suppression information S2.

  In the screen Sc4, in the graph Gr2, the vertical axis indicates power and the horizontal axis indicates time. In this example, in the graph Gr2, a rectangle indicating a control request of 200 kW from 10:00 to 12:00 based on the PV suppression period and the requested power R2 included in the suppression information S2 is drawn.

  In addition, in “PV output suppression plan candidates”, the contents of three pieces of candidate information are displayed in the order of indexes. “Expected achievement rate (%)” is a value obtained by dividing the expected supply suppression power value by the requested power R2 in percentage. “Supply suppression power amount expected (kW)” and “Payment incentives (yen)” are supply suppression power expectation value and cost, respectively. The “number of selected resources” is the number of customer IDs extracted by the power management server 102. The “control condition” is a condition registered in advance by an operator, for example.

  Further, by performing an operation for selecting the “recreate” button on the terminal device 171, for example, it is possible to recreate a plurality of candidates and reset the “control condition”. In this case, a plurality of candidates are recreated by performing the recommendation process RP4 in the power management server 102.

  With reference to FIG. 14 and FIG. 15, next, the terminal device 171 performs an input reception process (step S908).

  More specifically, the operator refers to the screen Sc4 and performs an operation on the terminal device 171 to select a “select this candidate” button corresponding to No. 1, for example.

  The accepting unit 64 accepts an operator's operation, creates operation information indicating the accepted operation, and outputs the created operation information to the notification unit 65.

  Upon receiving the operation information from the reception unit 64, the notification unit 65 transmits the received operation information to the power management server 102 (step S910).

  Next, the power management server 102 performs request information creation processing (step S912). More specifically, the processing unit 32 in the power management server 102 creates request information having contents based on candidate information selected from the three candidate information created by itself.

  Here, since the PV output suppression is not urgent, the processing unit 32 creates request information based on the received operation information when receiving the operation information from the terminal device 171 via the communication unit 21.

  More specifically, the processing unit 32 recognizes that the candidate information with the index of 1 is selected by the operator based on the operation information. From the candidate information with the index of 1, each customer ID and each demand The supply suppression power allocated to the consumer indicated by the house ID is acquired.

  And the process part 32 acquires apparatus ID corresponding to each acquired customer ID from management information as a destination of request information, and respond | corresponds to each apparatus ID, PV suppression period, and corresponding supply suppression power. Create request information including.

  On the other hand, in the case of urgent PV output suppression (YES in step S902), the processing unit 32 selects candidate information from the three candidate information created by itself according to the specified criteria, and sets the selected candidate information as the selected candidate information. Create request information based on the content. Here, the specified criteria are, for example, as shown in FIG. 15, “Achievement rate expected (%)”, “Supply suppression power amount expected (kW)”, “Payment incentives (yen)” and “Selected” This is a criterion using any one of “the number of resources”.

  The processing unit 32 outputs the created request information to the communication unit 21.

  Referring to FIG. 13 again, next, when receiving the request information from the processing unit 32, the communication unit 21 transmits the received request information to the customer apparatus 202 indicated by the destination included in the request information. (Step S328).

  Next, when each customer apparatus 202 receives request information from the power management server 102, it performs a request information registration process for registering the received request information (step S330).

  Next, each customer apparatus 202 transmits response information indicating whether or not to permit the contents of the request information to the power management server 102 (step S332).

  Next, each customer apparatus 202 periodically transmits performance value information indicating the performance of its own PV suppression request to the power management server 102 (step S334).

  Next, for example, after the request information is notified by the communication unit 21, the processing unit 32 in the power management server 102 determines whether or not a request regarding suppression of power supply to the system can be achieved (step S336).

  More specifically, the processing unit 32 receives response information and actual value information from each consumer device 202 via the communication unit 21, and based on the response information, actual value information, and suppression information S2, the transmission / distribution company It is determined whether or not adjustment for satisfying the content of the suppression information S2 from the server 141 is necessary.

  When determining that the adjustment is necessary (YES in step S336), the processing unit 32 creates new candidate information (step S344). Specifically, the processing unit 32 performs a recommendation process RP4.

  On the other hand, when determining that the adjustment is not necessary (NO in step S336), the processing unit 32 transmits a permission response signal indicating permission of the suppression information S2 to the transmission / distribution company server 141 via the communication unit 21. (Step S338).

  Next, the renewable energy provider server 131 transmits a permission response signal indicating that the suppression information S3 is permitted to the transmission / distribution provider server 141 (step S340).

  Next, when the power transmission / distribution provider server 141 receives the permission response signals from the renewable energy provider server 131 and the power management server 102, it performs a recording process for recording the received permission response signals (step S342).

  The order of steps S302 and S304 is not limited to the above, and the order may be changed.

  The order of steps S332 and S334 is not limited to the above, and the order may be changed.

  Next, when determining that the degree of achievement has not reached the target (YES in step S406), the processing unit 32 performs a recommendation process RP5 (step S408). Here, since PV output suppression is being executed, the processing unit 32 performs the recommendation process RP5 without making an inquiry to the operator, for example.

  More specifically, the processing unit 32 creates, for example, three candidate information. Specifically, for example, the processing unit 32 creates candidate information created before or after starting PV output suppression, that is, candidate information obtained by increasing or decreasing the number of customer IDs included in the pre-start candidate information, or pre-start candidate information. Candidate information including a customer ID that is not included in the pre-start candidate information is created, or candidate information including a customer ID of a customer belonging to another group is created in the pre-start candidate information.

  Then, for example, the processing unit 32 selects candidate information from among the three candidate information created by the processing unit 32 in accordance with a designated standard.

  Based on the selected candidate information and management information, the processing unit 32 creates request information for each customer whose PV output suppression content is to be changed, and outputs the created request information to the communication unit 21.

  Next, when receiving the request information from the processing unit 32, the communication unit 21 transmits the received request information to the consumer device 202 indicated by the destination included in the request information (step S410).

  Next, when each customer device 202 whose PV output suppression content is to be changed receives request information from the power management server 102, it performs a request information registration process for registering the received request information (step S412).

  Next, each customer device 202 subject to change of PV output suppression content executes PV output suppression according to the request information (step S414).

  On the other hand, if the processing unit 32 determines that the achievement level has reached the target (NO in step S406), the processing unit 32 does not perform the recommendation process RP5.

  The processes in steps S404 to S414 are repeated, for example, periodically until the PV output suppression is finished.

  Next, each consumer device 202 periodically transmits the actual value information to the power management server 102 after executing the PV output suppression (step S416).

  Next, the power management server 102 performs aggregation processing. More specifically, the processing unit 32 in the power management server 102 receives the actual value information from each consumer device 202 via the communication unit 21, and participates in PV output suppression based on the actual value information and the suppression information S2. The result of the supply suppression electric power in the PV suppression period of each consumer who did it is totaled (step S418).
