[Embodiment]
(Power management system)
Hereinafter, the power management system according to the embodiment will be described. FIG. 1 is a diagram illustrating a power management system 1 according to the embodiment. As shown in FIG. 1, the power management system 1 includes a customer facility 100, a network 200, a lower management server 300, and a higher management server 400.

  The customer facility 100 includes a customer communication device 110, a load 120, and a distributed power source 130. The customer communication device 110 is a communication device provided in the customer facility 100 and communicates with the lower management server 300 or the upper management server 400.

  The customer communication device 110 is a device (Energy Management System) that manages the power of equipment provided in the customer facility 100 or a PCS (Power Conditioning System) that controls the distributed power supply 130. The load 120 is a device that consumes power. The load 120 includes devices such as a refrigerator, lighting, an air conditioner, and a television, for example. The load 120 may be a single device or may include a plurality of devices. The distributed power supply 130 is a device that generates power. The distributed power supply 130 includes devices such as a solar cell, a fuel cell, and a storage battery, for example. The distributed power supply 130 may be a single device or may include a plurality of devices.

  In the embodiment, the customer facility 100 </ b> A, the customer facility 100 </ b> B, and the customer facility 100 </ b> C are illustrated as the customer facility 100. The customer facility 100A, the customer facility 100B, and the customer facility 100C have the same configuration. In the embodiment, the customer facility 100 includes three customer facilities 100A to 100C. However, the present invention is not limited thereto, and may be one customer facility 100 or a plurality of customers. The facility 100 may be used.

  The network 200 may be a communication unit that connects the customer facility 100 and the lower management server 300. Specifically, the network 200 is a communication line, for example, the Internet. The network 200 is provided by, for example, a provider contracted by each customer facility 100. The network 200 may be a dedicated line.

  The lower management server 300 is a server belonging to an aggregator such as a power distribution company. The aggregator is a business operator that manages the tide flow rate or the reverse tide flow rate of the customer facility 100 contracted with the aggregator.

  In the embodiment, the lower management server 300 </ b> A and the lower management server 300 </ b> B are illustrated as the lower management server 300. The lower management server 300A and the lower management server 300B have the same configuration. There may be one lower management server 300 or a plurality of lower management servers 300. The lower management server 300 may be integrated with the upper management server 400.

  The lower management server 300A and the lower management server 300B may manage different customer facilities 100, or may manage the customer facilities 100 in duplicate. The case where a plurality of lower-level management servers 300 overlap and manage the customer facility 100 is, for example, the case where the lower-level management server 300A and the lower-level management server 300B manage the customer facility 100A.

  The upper management server 400 is a server belonging to an electric power company such as an electric power company. The electric power company may entrust management of the tide flow rate or the reverse tide flow rate of the customer facility 100 to the aggregator.

  In the embodiment, the upper management server 400 transmits a tidal current suppression message (for example, DR; Demand Response) that requests suppression of tidal flow (power supply amount) to the customer facility 100 from the power system. The host management server 400 transmits a reverse flow suppression message requesting suppression of the reverse flow to the power system from the customer facility 100. In the embodiment, the power flow suppression message and the reverse power flow suppression message are collectively referred to as a power command message.

  Here, the tidal current suppression message includes information indicating the degree of suppression of the amount of power (tidal flow rate) supplied from the power system to the customer facility 100. The suppression degree may be represented by an absolute value (for example, OO kW) of the electric energy (tidal flow rate). Alternatively, the degree of suppression may be represented by a relative value of electric energy (tidal flow rate) (for example, a decrease in OO kW). Or the suppression degree may be represented by the suppression rate (for example, (circle)%) of electric energy (tidal flow).

  Alternatively, the tidal current suppression message may include information indicating a power purchase price that is a price of tidal current from the power system. By setting a high price as the power purchase price, it is expected that the amount of power (tidal flow) supplied from the power system to the customer facility 100 will be suppressed.

  The reverse power flow suppression message includes information indicating the degree of suppression of the amount of power (reverse power flow) output from the customer facility 100 to the power system. Specifically, the reverse power flow suppression message includes information indicating the degree of suppression of the output of the distributed power supply. The suppression degree may be represented by an absolute value (for example, OO kW) of the output of the distributed power source. Alternatively, the degree of suppression may be represented by a relative value of the output of the distributed power source (for example, a decrease in OO kW). Alternatively, the suppression degree may be expressed as a suppression ratio (for example, OO%) of the output of the distributed power source. The suppression ratio may be a ratio with respect to an output that is certified as an output capability of the PCS that controls the distributed power supply (hereinafter referred to as equipment certified output) when the distributed power supply is installed in the customer facility 100. When the output capability of the distributed power supply and the output capability of the PCS are different, the facility certified output is the smaller output capability of these output capabilities. In the case where a plurality of PCSs are installed, the facility authorization output is the sum of the output capacities of the plurality of PCSs.

  Here, as a format of the power flow suppression message and the reverse power flow suppression message, a format conforming to an automatic demand response (ADR) can be used. The communication between the upper management server 400 and the lower management server 300 and the communication between the lower management server 300 and the customer facility 100 may be performed by a method based on the same standard. As a method conforming to the same standard, for example, a method conforming to the Open ADR standard can be used.

  In the embodiment, the power command message includes a suppression schedule that is a schedule for requesting suppression of tidal flow from the power system to the customer facility 100 or suppression of reverse power flow from the customer facility 100 to the power system. In the suppression schedule, the schedule related to suppression of tidal current or reverse power flow can be set in units of 30 minutes. The suppression schedule may be calendar information expressed in a calendar format. The suppression schedule may include a one-day schedule, a one-month schedule, or a one-year schedule.

  The power command message may include an access date and time when the customer facility 100 accesses the lower management server 300 next. When it is necessary to make an inquiry about the presence or absence of the power command message from the customer facility 100 to the subordinate management server 300, the security can be improved by specifying the next access date and time with the power command message.

(Customer communication equipment)
Below, the customer communication apparatus which concerns on embodiment is demonstrated. FIG. 2 is a diagram illustrating the customer communication device 110 according to the embodiment. The customer communication device 110 includes a communication unit 111, a storage unit 112, and a control unit 113.

  The communication unit 111 is configured by a communication module or the like, and communicates with the lower management server 300 or the upper management server 400. Here, a case where the communication unit 111 communicates with the lower management server 300 is illustrated. For example, the communication unit 111 receives a power command message including a power flow suppression message or a reverse power flow suppression message from the lower management server 300 via the network 200 (communication line).

  Here, the communication unit 111 receives the power command message at a predetermined timing. For example, in the case where the power command message is received once a day, the predetermined timing is a time determined in the day. The communication unit 111 may request the lower management server 300 to transmit a new power command message (for example, transmission of “oadPoll” illustrated in FIG. 5).

  In the embodiment, the communication unit 111 communicates with the lower-level management server 300 by a method compliant with the Open ADR standard. The communication unit 111 transmits a predetermined message having a predetermined format to the lower management server 300. The predetermined format is a format defined by the Open ADR standard.

  The storage unit 112 is configured by a nonvolatile memory or an HDD (Hard Disk Drive), and stores various types of information. For example, the storage unit 112 stores an existing power command message that is a received power command message.

  The control unit 113 is configured by a CPU, a memory, and the like, and controls the customer communication device 110. Specifically, the control unit 113 stores a power command message received from the lower management server 300 in the storage unit 112. The control unit 113 executes suppression control of the tide flow rate or the reverse tide flow rate according to the existing power command message stored in the storage unit 112. The tidal flow suppression control includes control for reducing the power consumption of the load 120 and control for increasing the output power of the distributed power supply 130 (for example, a storage battery). The suppression control of the reverse power flow is a control for reducing the output power of the distributed power supply 130 (for example, a solar battery).

  In the embodiment, the control unit 113 stores the new power command message, which is a power command message newly received from the lower management server 300, at the predetermined timing, and is stored in the storage unit 112 in the target period. In accordance with the existing power command message that is a power command message, suppression control that suppresses the tidal flow or reverse power flow is executed. Examples of cases where reception is not possible at a predetermined timing include a case where reception is delayed with respect to a predetermined timing, or a case where reception is not possible at a predetermined timing.

  When the control unit 113 receives the new power command message at a timing later than the predetermined timing, the control unit 113 receives the new power command message based on the comparison result between the new power command message and the existing power command message. The suppression control in the subsequent correction period is corrected.

  For example, in the control unit 113, the suppression amount in the target period when the suppression control is executed according to the existing power command message is smaller than the suppression amount in the target period when it is assumed that the suppression control is executed according to the new power command message. In this case, the suppression control in the correction period is corrected. In such a case, the control unit 113 corrects the suppression control in the correction period so that the suppression amount is larger than the suppression amount in the correction period when it is assumed that the suppression control is executed according to the new power command message.

  On the other hand, the control unit 113 controls the suppression amount in the target period when the suppression control is executed according to the existing power command message, than the suppression amount in the target period when it is assumed that the suppression control is executed according to the new power command message. If it is larger, the suppression control may be executed according to the new power command message without correcting the suppression control.

  Even if the control unit 113 can receive the new power command message at a timing later than the predetermined timing, the control unit 113 corrects the suppression control in the correction period depending on the comparison result between the new power command message and the existing power command message. It is not necessary to execute. For example, when the content of the new power command message is the same as that of the existing power command message, the correction of the suppression control in the correction period is not executed. Alternatively, if the suppression amount in the target period when the suppression control is executed according to the existing power command message is larger than the suppression amount in the target period when it is assumed that the suppression control is executed according to the new power command message Correction of suppression control in the period is not executed.

  Here, when the power command message is a reverse power flow suppression message, the control unit 113 uses the suppression amount in the target period when the suppression control is executed according to the existing power command message as the power generation result in the customer facility 100. You may calculate based on. The power generation record in the customer facility 100 may be, for example, the output power of the distributed power supply 130 (for example, a solar battery), and the output of the PCS that controls the solar battery or the multi-PCS that controls both the solar battery and the storage battery. Electric power may be used.

  When the power command message is a power flow suppression message, the control unit 113 may correct the operation schedule of the distributed power source 130 (for example, one of the storage battery and the fuel cell) in the correction period. For example, the control unit 113 can suppress the tidal flow by correcting the operation schedule so as to increase the discharge power of the storage battery or the output power of the fuel cell. In other words, the convenience in the customer facility 100 can be improved by realizing the suppression amount for a plurality of days for which the suppression amount is determined for each day over a plurality of days.

  Further, when correcting the suppression control in the correction period after the timing when the new power command message is received, the communication unit 111 may transmit the correction to the lower management server 300. The content transmitted to the lower management server 300 may be only the presence or absence of correction, or the content of correction.

  Alternatively, the communication unit 111 may transmit the correction content together when transmitting the actual value of the suppression amount to the lower management server 300. By transmitting the actual value of the suppression amount and the correction content, the lower-level management server 300 can know why the actual value is such. As the actual value of the suppression amount, for example, the value of a PCS track record can be used.

(Management server)
Hereinafter, the management server according to the embodiment will be described. Here, the lower management server 300 is illustrated as the management server. However, the upper management server 400 may be the management server. FIG. 3 is a diagram illustrating the lower management server 300 according to the embodiment. As shown in FIG. 3, the lower management server 300 includes a communication unit 310 and a control unit 320.

  The communication unit 310 includes a communication module and the like, and communicates with the customer facility 100 and the upper management server 400. For example, the communication unit 310 receives a power command message including a power flow suppression message or a reverse power flow suppression message from the upper management server 400.

  The communication unit 310 transmits a power command message including a power flow suppression message or a reverse power flow suppression message to the customer facility 100 via the network 200 (communication line). Since the management of the tidal flow or the reverse tidal flow of the customer facility 100 is entrusted to the aggregator (lower management server 300), the content of the power command message transmitted to the customer facility 100 is the power received from the higher management server 400. It may be different from the content of the command message. More specifically, the power command message sent from the higher-level management server 400 may be achieved at each customer facility 100 or should be achieved at a plurality of customer facilities 100. Also good. When the power command message is to be achieved by a plurality of customer facilities 100, the lower management server 300 selects an appropriate customer facility 100. Then, the lower management server 300 transmits a power command message to be achieved at each customer facility 100 to the selected customer facility 100.

  In the embodiment, the communication unit 310 communicates with the customer communication device 110 by a method based on the Open ADR standard.

  The control unit 320 includes a CPU, a memory, and the like, and controls the lower management server 300. For example, the control unit 320 determines at least one of the transmission partner and contents of the power command message.

(Power command message)
Hereinafter, the power command message according to the embodiment will be described. FIG. 4 is a diagram illustrating a power command message according to the embodiment. In FIG. 4, the existing power command message and the new power command message are illustrated, and the suppression schedule for five days is illustrated. In FIG. 4, the reverse power flow suppression message is illustrated as the power command message.

  In FIG. 4, “date” indicates the date on which the control for suppressing the reverse power flow is executed. The “allowable output amount” is an amount in which the output of the distributed power supply 130 (for example, a solar cell) is allowed in the case where the suppression control of the reverse power flow is executed.

  For example, in the case illustrated in FIG. 4, a case where the target period is “May 26” is illustrated. In such a case, when the reverse power flow suppression control is executed in accordance with the existing power command message, the allowable output amount is 13 kW. On the other hand, when the reverse power flow suppression control is executed according to the new power command message, the allowable output amount is 13 kW.

  Here, when a new power command message cannot be received at a predetermined timing at which a power command message for performing suppression control for the target period should be received, the output of the distributed power supply 130 (for example, a solar cell) is 3 kW (13 kW-10 kW). ). In other words, the suppression amount in the target period when the suppression control is executed according to the existing power command message is about 3 kW smaller than the suppression amount in the target period when it is assumed that the suppression control is executed according to the new power command message.

  Therefore, in the embodiment, the control unit 113 corrects the suppression control in the correction period after the timing when the new power command message is received. The correction period is not particularly limited, and is, for example, “May 27”. When the correction period is “May 27”, the control unit 113 changes the allowable output amount on “May 27” from 10 kW to 7 kW, thereby allowing the allowable output amount on “May 27”. Is reduced by about 3 kW. That is, the control unit 113 increases the suppression amount by about 3 kW than the suppression amount in the correction period when it is assumed that the suppression control is executed according to the new power command message.

(Management method)
Hereinafter, a management method according to the embodiment will be described. 5 and 6 are diagrams illustrating a management method according to the embodiment.

  As shown in FIG. 5, in step S <b> 101, the customer communication device 110 transmits an inquiry message (for example, oadrPoll) for inquiring whether there is a message to the customer communication device 110 to the lower management server 300. An inquiry message (for example, oadrPoll) is an example of a request message for requesting transmission of a power command message. The process of step S101 is performed at a predetermined cycle, and FIG. 5 illustrates steps S101A to C as step S101.

  In step S <b> 102, the lower management server 300 transmits a message including the power command message (for example, oaderDistributionEvent) to the customer communication device 110. In FIG. 5, steps S102A to S102C are illustrated as step S102.

  In step S103, the consumer communication device 110 executes suppression control according to the power command message. In FIG. 5, steps S103A to S103 are exemplified as step S103.

  Here, consider a case where the new power command message cannot be received in step S102B and the new power command message can be received in step S102C. In such a case, for example, the period in which step S103B is executed is the target period, and the period in which step S103C is executed is the correction period.

  Specifically, in step S103B, the customer communication device 110 executes suppression control that suppresses the tide flow rate or the reverse tide flow rate according to the existing power command message stored in the storage unit 112. On the other hand, in step S103C, the consumer communication device 110, based on the comparison result between the new power command message received in step S102C and the existing power command message, the correction period after the timing when the new power command message is received. The suppression control in is corrected.

  Such an operation of the customer communication device 110 is represented by, for example, a flowchart shown in FIG.

  As shown in FIG. 6, in step S201, the customer communication device 110 fails to receive a new power command message at a predetermined timing (for example, step S102B shown in FIG. 5). The predetermined timing may be, for example, a time designated by the customer communication device 110 or a time designated by the lower management server 300. When the customer communication device 110 fails in reception, the customer communication device 110 executes suppression control that suppresses the tidal flow or the reverse tidal flow according to the existing power command message that is the power command message stored in the storage unit 112 (for example, FIG. 5). Step S103B).

  In step S202, the new power command message is successfully received at a timing later than the predetermined timing (for example, step S102C shown in FIG. 5).

  In step S <b> 203, the consumer communication device 110 determines whether or not suppression control correction in the correction period is necessary based on the comparison result between the new power command message and the existing power command message. For example, the consumer communication device 110 uses the suppression amount in the target period when it is assumed that the suppression amount in the target period when the suppression control is executed according to the existing power command message is executed according to the new power command message. Is also smaller, it is determined that the suppression control in the correction period is corrected. On the other hand, the consumer communication device 110 has a suppression amount in the target period when it is assumed that the suppression amount in the target period when the suppression control is executed according to the existing power command message is executed according to the new power command message. If it is greater than the limit, it is determined that the suppression control in the correction period is not corrected. When the determination result is YES, the customer communication device 110 proceeds to the process of step S204. If the determination result is NO, the customer communication device 110 proceeds to the process of step S205.

  In step S204, the consumer communication device 110 corrects the suppression control in the correction period. Specifically, the consumer communication device 110 corrects the suppression control in the correction period so that the suppression amount is larger than the suppression amount in the correction period when it is assumed that the suppression control is executed according to the new power command message. .

  In step S205, the consumer communication device 110 does not correct the suppression control during the correction period. The consumer communication device 110 executes suppression control according to the new power command message.

(Function and effect)
When the customer communication device 110 according to the embodiment can receive the new power command message at a timing later than the predetermined timing, the customer communication device 110 can generate a new power command based on the comparison result between the new power command message and the existing power command message. The suppression control in the correction period after the timing when the message is received is corrected. According to such a configuration, it is possible to reduce unfairness between the customer facility 100 that has received a new power command message at a predetermined timing and the customer facility 100 that has not been able to receive a new power command message at a predetermined timing. Can do.
