A device control unit 14 is functionally included.
In addition, the processing device 11 stores a device database 15 in which information related to the amount of power of each of the plurality of electrical devices 2 is registered in the storage device of the own device 11.

The specifying unit 13 has a function of specifying an adjustment capability amount that can be adjusted with respect to the power amount (total power amount) of the plurality of electric devices 2 before adjusting the power amount of the plurality of electric devices 2. The specifying unit 13 specifies the adjustment capability amount (total adjustment capability amount) that can be realized when the total power amount is adjusted by controlling the plurality of electrical devices 2.
The identifying unit 13 refers to the device database 15 and identifies the overall adjustment capability amount.

FIG. 2 is a diagram illustrating an example of the device database 15.
As shown in FIG. 2, in the device database 15, a device ID, a device type, a baseline, an individual adjustment capability amount, a priority, and basic information are registered in association with each other.
The device ID is information for identifying each electric device 2. The device ID is associated with, for example, the communication address of the control terminal 4 of each electric device 2 and is used to specify a transmission destination of control information or the like to be transmitted to the control terminal 4 based on the device ID. It is done.
The device type is a device name indicating each electric device 2 such as a solar power generation device or a power storage device as shown in FIG.

The baseline is a value of an average electric energy that is a reference for each electric device 2. The baseline of a power generation device such as a solar power generation device is the average amount of power generated by the power generation device over a predetermined period. The baseline of a power storage device is an average charge / discharge power amount of the power storage device during a predetermined period. The baseline of a load device such as an air conditioner or an electric water heater is the average power consumption of the load device over a predetermined period.
In the present embodiment, the amount of power in the forward tide direction is positive, and the amount of power in the reverse tide direction is negative. Therefore, the amount of power generated by the power generation device and the amount of power discharged by the power storage device to the power system are negative, and the amount of power consumed by the load device and the amount of power charged in the power storage device are positive.

  In the device database 15, for example, a baseline between midnight and 0:30 am, a baseline between 0:30 am and 1:00 am, for example, a predetermined period set for 30 minutes Each baseline is registered for one day (24 hours). That is, the baseline of each electrical device 2 is registered in the device database 15 over time. Note that the predetermined period for obtaining the baseline corresponds to a unit period for an adjustment period set by the specifying unit 13 described later.

The baseline can be registered with a preset value, or the control terminal 4 can acquire the power amount of the electrical device 2 for the past several days over time, and the power for each predetermined period in the past few days. It is also possible to obtain the quantity and update the baseline registered in the device database 15 at any time. For example, a later-described device control unit 14 having a function of controlling each electric device 2 is caused to sequentially acquire information on the electric energy from each electric device 2, obtain a baseline for each predetermined period, and update the device database 15. It can be constituted as follows.
In the present embodiment, the baseline is expressed as power consumption.

The individual adjustment capability amount indicates an amount that can be individually adjusted with respect to the electric energy of each electrical device 2.

The individual adjustment capability amount registered in the device database 15 is set in advance to a value that can be adjusted based on the rating and performance of the electric device 2 and the corresponding baseline value.
Since the baseline is expressed as the power consumption amount, when the individual adjustment capability amount is a positive value, the power amount of the electric device 2 is adjusted in the direction in which the power consumption amount increases. Further, when the individual adjustment capability amount is a negative value, the electric energy of the electric device 2 is adjusted in a direction in which the electric power consumption decreases.

Note that the overall adjustment capability amount is an adjustment capability amount that can be realized when the overall power amount of the plurality of electrical devices 2 is adjusted as described above. This overall adjustment capability amount is also expressed as a value based on the baseline, as is the case with the individual adjustment capability amount. The overall adjustment capability amount is based on the overall baseline obtained by adding the baselines of all the plurality of electrical devices 2.
Further, since the overall baseline is also expressed as the power consumption amount, when the overall adjustment capability amount is a positive value, the overall power amount is adjusted in the direction in which the power consumption amount increases. Further, when the total adjustment capacity amount is a negative value, the total power amount is adjusted in a direction in which the power consumption amount decreases.

  The priority is information for determining an electrical device 2 that preferentially adjusts the electric energy among the electrical devices 2 and is set in advance for each electrical device 2. By adjusting the priority, it is possible to limit the power supply and demand from being adjusted for a specific electrical device 2 among the electrical devices 2.

  The basic information is information such as a rated value related to basic performance of each electrical device 2. For example, in the case of a power storage device, it is a power storage capacity or the like, in the case of a power generation device, it is a power generation amount or the like, and in the case of a load device, it is power consumption or the like.

The communication control unit 12 has a function of transmitting the overall adjustment capability amount specified by the specifying unit 13 to the server device 5.
Further, the communication control unit 12 has a function of receiving a prior notice regarding the demand response request from the server device 5 before transmitting the demand response request.
Further, the communication control unit 12 has a function of receiving a demand response request from the server device 5.
The demand response request is a notification for the server device 5 of the power company to request the server device 3 to adjust the amount of power. When the server apparatus 3 receives the demand response request, the server apparatus 3 adjusts the total power amount of the plurality of electric devices 2 as a whole.

When the device control unit 14 receives and accepts a demand response request from the server device 5, the device control unit 14 has a function of remotely controlling the plurality of electric devices 2 and adjusting the total electric energy. In addition, upon receiving and receiving a prior notification from the server device 5, the device control unit 14 is necessary to remotely control the plurality of electric devices 2 and create an overall adjustment capability amount required based on the demand response request. A function of causing a plurality of electrical devices 2 to execute such prior control.
The device control unit 14 remotely controls each electrical device 2 by transmitting a control command to each control terminal 4.

[System operation]
FIG. 3 is a sequence diagram for explaining the operation of the power management system of the present embodiment.
First, the server device 3 of the aggregator specifies various information (Step S1). The specifying unit 13 of the server apparatus 3 refers to the device database 15 and specifies the total adjustment capacity amount.
In addition, the specifying unit 13 specifies a period during which adjustment based on the total adjustment capability amount is executed together with the total adjustment capability amount.

For example, the specifying unit 13 divides the period from the present to the seventh day ahead at an interval of 30 minutes, and specifies the total adjustment capacity amount for each divided unit period. That is, the specifying unit 13 specifies in advance an overall adjustment capability amount that can adjust the electric energy in each unit period that is a future period.
Thereby, the specific | specification part 13 specifies the unit period which performs adjustment by the specified total adjustment capability amount while specifying the total adjustment capability amount. Note that a unit period during which the server apparatus 3 can execute adjustment based on the total adjustment capability amount is also referred to as an adjustment period (adjustable period).

  The specifying unit 13 specifies the total adjustment capability amount based on a preset target value for specifying the total adjustment capability amount. The specifying unit 13 refers to the device database 15 and specifies the electric device 2 to be controlled from each of the plurality of electric devices 2 so that the overall adjustment capability amount becomes the target value.

The specifying unit 13 specifies the electric device 2 to be controlled based on the individual adjustment capability amount and priority of each electric device 2 registered in the device database 15. The specifying unit 13 adds the individual adjustment capability amounts of the electrical devices 2 according to the priority. The specifying unit 13 adds the individual adjustment capability amounts of the electrical devices 2 until the addition value of the individual adjustment capability amounts satisfies the target value.
When determining that the added value of the individual adjustment capability amount has reached the target value, the specifying unit 13 specifies the added value as the overall adjustment capability amount. Further, the specifying unit 13 specifies the electric device 2 to which the individual adjustment capability amount is added as a control target.
The specifying unit 13 performs the same process for each adjustment period, and specifies the total adjustment capacity amount and the electric device 2 to be controlled for each adjustment period.

FIG. 4 is a table showing an example of the total adjustment capability amount specified by the specifying unit 13 and the adjustment period corresponding to the total adjustment capability amount.
In FIG. 4, the total adjustment capability amount and the adjustment period are represented in association with each other.
In FIG. 4, the adjustment period includes a date and a time zone. The date represents the date of each adjustment period. In the time zone, the start time and end time of each adjustment period are shown.
Three plans are represented in the total adjustment capacity, and the total adjustment capacity is represented in each of the three plans.

The specifying unit 13 of the present embodiment is configured to specify three total adjustment capability amounts based on three different target values. As a result, three plans having different values for the overall adjustment capability are set.
For example, among the three plans, the plan A and the plan B have the total adjustment capacity amount set so as to reduce the total power amount from the total baseline. In the plan A and the plan B, the total power adjustment amount is set to a negative (minus) value in order to adjust the total power amount to decrease from the total baseline. That is, in the case of Plan A and Plan B, the power consumption of the plurality of electric devices 2 is adjusted so as to reduce the power consumption and reduce the power demand in the power company.
The difference between the plan A and the plan B is the size of the overall adjustment capability amount, and the plan A is set to a value with a larger overall adjustment capability amount.

  In the plan C, the total adjustment capacity amount is set so as to increase the total power amount from the total baseline by charging the electric device 2 to be controlled. In the plan C, the total power adjustment amount is set to a positive (plus) value in order to adjust the total power amount so as to increase from the total baseline. That is, in the case of plan C, the power consumption of the plurality of electrical devices 2 is adjusted so as to increase the power consumption and increase the power demand at the power company.

For example, in FIG. 4, in the plan A in which the adjustment period is ** month ** day “11: 00-11: 30” (11 am to 11:30 am), the total adjustment capacity amount is set to −2 kWh. .
This is because the server device 3 can adjust the total electric energy of the plurality of electric devices 2 in the direction of decreasing by 2 kWh from the entire baseline in the time zone of “11: 00-11: 30” on the day of the month. Is shown.

The specifying unit 13 specifies the total adjustment capacity amount of each adjustment period included in the period from the present to the seventh day ahead for each plan.
Thereby, the specifying unit 13 specifies a plurality of overall adjustment capability amounts having different values and corresponding adjustment periods.
Further, the specifying unit 13 specifies the total adjustment capability amounts having the same adjustment period and different values from each other by three plans as identification information for identifying the values.

Further, when the specifying unit 13 specifies the total adjustment capability amount, the specification unit 13 sets the content related to the advance control that is a process for creating the total adjustment capability amount.
The pre-control is a process that is executed in advance by the electrical device 2 specified as a control target, and is a process that is necessary to create an overall adjustment capability amount for power amount adjustment of the plurality of electrical devices 2.

The specifying unit 13 sets the content related to the prior control for each of the specified overall adjustment capacity amounts.
The specifying unit 13 refers to the baseline, the individual adjustment capability amount, and the basic information related to the electric device 2 to be controlled registered in the device database 15 and sets the content related to the prior control.

  FIG. 5 is a diagram illustrating an example of content related to the advance control set by the specifying unit 13. In the example illustrated in FIG. 5, a case where the electrical device 2 to be controlled is a power storage device is illustrated.

In FIG. 5, the adjustment period corresponds to the adjustment period shown in FIG.
Similar to FIG. 4, three plans (plans A to C) are shown in the contents related to the prior control. Each of the three plans shows the contents related to prior control.
These three plans correspond to the three plans in FIG.
In FIG. 5, for example, in the portion of plan A whose adjustment period is “month, day” “11: 00-11: 30”, the plan whose adjustment period is “11: 00-11: 30” in FIG. The contents related to the prior control corresponding to the total adjustment capacity amount of A are shown. Similarly, in the portion of plan B whose adjustment period is ** month ** day "11: 30-12: 00", the adjustment period in Figure 4 is ** month ** day "11: 30-12: 0". The contents regarding the pre-control corresponding to the overall adjustment capacity amount of the plan B are shown.
As described above, in FIG. 5, the contents related to the prior control and the adjustment period of the overall adjustment capability amount in FIG. 4 are shown in association with each other.

The contents relating to the pre-control indicate the time zone of pre-control, the control mode, the total charge amount, and the pre-control start time.
The pre-control time zone indicates a time zone in which the pre-control is executed.
The control mode indicates the processing content executed in the prior control. In the case of FIG. 5, since the electric device 2 to be controlled is a power storage device, either charge or discharge is represented as a control mode.
The total charge amount represents the total charge amount of the power storage device to be controlled.
The advance control start time represents the start time (start timing) at which the electrical device 2 that is the control target starts the advance control.

For example, in FIG. 5, in the plan A in which the adjustment period is “month / day / day” “11: 00-11: 30”, the total adjustment capacity amount is 2 kWh (FIG. 4). As shown in FIG. 5, the contents of the prior control for adjustment based on the total adjustment capacity amount are executed in the time zone of “9: 00-9: 30” and “9: 30-10: 00” on the same day. , Charging is performed so that the total charging amount becomes 1 kWh at “9: 00-9: 30”, and charging is performed so that the total charging amount becomes 2 kWh at “9: 30-10: 00”.
The advance control start time is set to 9:00, which is the start time of the advance control time zone.

When the server apparatus 3 executes the plan A in which the adjustment period is ** month ** day "11: 00-11: 30", the server apparatus 3 performs pre-control of the above contents from 9:00 of ** month ** day. Start and run. Thereby, the electric energy which can be discharged can be ensured and the whole adjustment capability amount for the electric energy adjustment of the some electric equipment 2 can be created.
Therefore, the server device 3 can adjust the total electric energy of the plurality of electrical devices 2 so as to increase by 2 kWh from the entire baseline at “11: 00-11: 30” on the day of ** Can be executed reliably.

As described above, the specifying unit 13 specifies a plurality of overall adjustment capability amounts corresponding to each adjustment period and each plan, and sets the content of the prior control for each specified overall adjustment capability amount.
The specifying unit 13 stores the specified total adjustment capability amount and the content of the prior control in the storage device of the processing device 11 as a list as illustrated in FIGS. 4 and 5.

  The specifying unit 13 specifies the total adjustment capacity amount without considering the influence on the adjustment in the adjustment period other than the corresponding adjustment period. Further, when setting the content of the advance control, the specifying unit 13 does not consider the influence on the adjustment in the time zone other than the time zone of the advance control to be set, as in the case of specifying the total adjustment capacity amount. Set.

Returning to FIG. 3, in step S <b> 1, when a plurality of overall adjustment capacity amounts corresponding to each adjustment period and each plan are specified and the content of the prior control is set, the server device 3 (the communication control unit 12 thereof) Then, an adjustment capability amount notification for notifying a plurality of specified overall adjustment capability amounts and the like is transmitted to the server device 5 (step S2).
The server device 3 uses the power adjustment information including information on the plurality of overall adjustment capability amounts specified in step S1 and the adjustment periods associated with the plurality of overall adjustment capability amounts as information on the adjustment capability amount notification. Send to.

FIG. 6 is a diagram illustrating an example of power adjustment information transmitted by the server device 3.
The power adjustment information shown in FIG. 6 includes a prior control start time corresponding to each total adjustment capability amount in addition to a plurality of overall adjustment capability amounts corresponding to each adjustment period and each plan shown in FIG.

The server device 3 transmits power adjustment information including a plurality of overall adjustment capability amounts corresponding to each adjustment period and each plan, and a pre-control start time corresponding to each overall adjustment capability amount.
The server device 3 is configured to perform identification of various types of information in step S1 and transmission of the adjustment capability amount notification in step S2 at a predetermined period, for example, once a day at a predetermined time.

  Returning to FIG. 3, the server device 5 of the power company that has received the power adjustment information outputs the power adjustment information to the operator of the server device 5, and the demand adjustment information is obtained from the plurality of overall adjustment capability amounts included in the power adjustment information. The operator is made to select one or a plurality of overall adjustment capability amounts for which a response request is to be made. The server device 5 causes the operator to specify and select the total adjustment capability amount based on the adjustment period corresponding to the total adjustment capability amount and the plan corresponding to the selected total adjustment capability amount.

The server device 5 receives selection information indicating the overall adjustment capability amount selected by the operator (step S3).
The selection information includes, as information, an adjustment period corresponding to the selected overall adjustment capability amount and a plan corresponding to the selected overall adjustment capability amount.
The server device 5 that has received the selection information determines transmission of a demand response request for requesting the adjustment of the electric energy with the overall adjustment capability amount indicated by the selection information. The server device 5 includes the selection information in the demand response request.

As described above, the power adjustment information transmitted by the server device 3 (a plurality of overall adjustment capability amounts included therein) is given to the server device 5 so that one or a plurality of whole items selected by the operator of the server device 5 are selected. It is possible to cause the server device 5 to determine transmission of a demand response request for requesting adjustment based on the adjustment capability amount.
That is, the power adjustment information transmitted by the server device 3 constitutes a transmission request for requesting the server device 5 to transmit a demand response request based on one or a plurality of overall adjustment capability amounts selected by the operator.

The power adjustment information includes the total adjustment capability amount for each adjustment period, and also includes different total adjustment capability amounts in the same adjustment period, such as Plan A-Plan C. Thus, a demand response request for requesting (requesting) adjustment by one or a plurality of overall adjustment capability amounts selected by the operator from among a plurality of overall adjustment capability amounts having different values and corresponding adjustment periods is transmitted. The request is requested from the server device 5.
Thereby, the operator of the server apparatus 5 can select the adjustment of the electric energy set to the required period and the required overall adjustment capability amount from the plurality of overall adjustment capability amounts.

Further, the server device 5 transmits a prior notice regarding the demand response request before transmitting the demand response request in accordance with the power adjustment information from the server device 3 (step S4).
The server device 5 transmits the selection information included in the prior notification.

The server device 5 transmits a prior notice regarding the demand response request that has been determined to be transmitted by the prior control start time corresponding to the selected overall adjustment capability amount.
As described above, the power adjustment information (included in the prior control start time) transmitted by the server device 3 is given to the server device 5, so that prior notification regarding the demand response request is sent to the server before the demand response request is transmitted. It can be transmitted to the device 5.
That is, the power adjustment information transmitted by the server device 3 constitutes a prior notification request for requesting the server device 5 to transmit a prior notification by the prior control start time.

  In the present embodiment, the power adjustment information includes both the overall adjustment capability amount and the advance control start time, thereby configuring both the transmission request and the advance notification request. The control start time can also be transmitted to the server device 5 as separate information. For example, information obtained by removing the advance control start time from the power adjustment information shown in FIG. 6 is transmitted to the server device 5 as a transmission request, and thereafter or simultaneously, the advance control start time is transmitted to the server device 5 as an advance notification request. Also good.

In addition, as shown in FIG. 4, the power adjustment information transmitted by the server device 3 is specified by plans (three plans A-plan C) for the total adjustment capability amounts having the same adjustment period and different values. ing.
Thereby, the server apparatus 5 specifies the total adjustment capability amount by the adjustment period and the plan as identification information. The server device 5 transmits selection information including, as information, an adjustment period corresponding to the selected overall adjustment capability amount and a plan corresponding to the selected overall adjustment capability amount.

That is, the power adjustment information as a transmission request transmitted by the server device 3 is a request for requesting the server device 5 to transmit a demand response request in which the total adjustment capability amount that requires adjustment is specified by the identification information.
As a result, the server device 3 can easily identify the overall adjustment capability amount requested by the server device 5.

  The server device 3 that has received the advance notification in step S5 identifies the overall adjustment capability amount selected by the operator of the server device 5 based on the selection information included in the advance notification. Accordingly, the server device 3 selects the selected overall adjustment capability amount, the adjustment period corresponding thereto, the content of the pre-control corresponding to the overall adjustment capability amount selected by the operator of the server device 5, and the electric device 2 to be controlled. Can be specified.

When the server device 3 (the device control unit 14) determines that the advance notification has been received by the advance control start time corresponding to the specified overall adjustment capability amount, the server device 3 (the device control unit 14) issues a control command for executing the advance control to the controlled electrical device. 2 (step S6).
The electric device 2 (the control processing unit 20) that has received the control command related to the pre-control executes the pre-control (step S7).

Note that even if the server apparatus 3 receives a prior notice after receiving the demand response request after the prior control start time, the server apparatus 3 issues a control command for executing the prior control to the electric device 2 to be controlled. May be transmitted.
In this case, the preliminary control is not completely completed until the adjustment of the electric energy is started for the plurality of electric devices 2, but the preliminary control can be executed to some extent. As a result, the adjustment of the electric energy can be performed more advantageously than when no prior control is executed.
In this way, even if the server device 3 receives the prior notification after the advance control start time has elapsed, the server device 3 performs the adjustment of the electric energy between the reception of the prior notification and the subsequent reception of the demand response request. It is possible to secure a period during which preparations are made.

  On the other hand, after transmitting the advance notice, the server device 5 of the power company waits for an operator to give a decision that the demand response request should be actually transmitted. The server device 5 determines whether or not the decision to transmit the demand response request has been received until it reaches an adjustment period during which the adjustment of the electric energy is executed (step S8).

When the determination of demand response request transmission is received before the adjustment period is reached, the server device 5 transmits a demand response request corresponding to the previously transmitted prior notification (step S9).
Upon receiving the demand response request from the server device 5 in step S10, the server device 3 (the device control unit 14) issues a control command for adjusting the electric energy to an appropriate timing for the electric device 2 to be controlled. (Step S11).
The server device 3 transmits a control command to the electric device 2 to be controlled so that the adjustment of the electric energy is executed in the adjustment period requested by the demand response request.
Note that the electrical device 2 to be controlled has finished the prior control when a control command for adjusting the electric energy is given.

  The electrical device 2 (the control processing unit 20) that has received the control command for adjusting the electric energy executes the adjustment of the electric energy (step S12). As a result, the server apparatus 3 adjusts the total power amount during the adjustment period in accordance with the demand response request from the server apparatus 5.

On the other hand, if the server apparatus 5 of the power company does not accept the demand response request transmission decision until the adjustment period is reached in step S8, the demand response request transmission is not performed and the process is terminated.
In this case, the server device 3 does not accept a demand response request corresponding to the prior notification transmitted from the server device 5 previously. Thus, when the adjustment period is reached, the server device 3 stops transmitting the control command for adjusting the electric energy.
Moreover, the electric equipment 2 which performed prior control finishes a process, without performing adjustment of electric energy.

  In this case, even if the demand response request from the server device 5 is not received after executing the pre-control, there is substantially no influence on the operating states of the plurality of electrical devices 2. For this reason, if the adjustment period is reached, the server device 3 can stop transmitting the control command to the plurality of electrical devices 2 for adjusting the electric energy.

As described above, the server device 3 according to the present embodiment adjusts the total electric energy of the plurality of electrical devices 2 based on the demand response request (adjustment request) transmitted from the server device 5 (external device). Yes, a specifying unit 13 that specifies an overall adjustment capability amount that can be adjusted with respect to the total electric energy of the plurality of electrical devices 2, and a communication control unit that transmits an adjustment capability amount notification (transmission request and advance notification request) to the server device 5. 12 (transmission unit).
In addition, the communication control unit 12 constitutes a reception unit that receives a demand response request and a prior notification transmitted by the server device 5.

According to the server device 3 configured as described above, the communication control unit 12 can receive a prior notification regarding a demand response request before receiving a demand response request from the server device 5. Therefore, the server device 3 secures a period during which preparation for executing adjustment based on the overall adjustment capability amount is performed on the plurality of electrical devices 2 after receiving the prior notification and subsequently receiving the demand response request. can do.
As a result, it is possible to suppress an error that occurs between the total adjustment capability amount obtained in advance and the adjustment amount that is adjusted when the power amount is actually adjusted based on the total adjustment capability amount.

In the present embodiment, the prior notification request transmitted by the server device 3 is a request for requesting the server device 5 to transmit the prior notification by the prior control start time. Further, when the server device 3 determines that the advance notification has been received by the advance control start time, the server device 3 transmits a control command for executing the advance control to the electric device 2 to be controlled.
Therefore, if the prior notification from the server device 5 can be received by the prior control start time, the prior control can be surely started from the prior control start time by the plurality of electrical devices 2.
As a result, it is possible to further suppress errors that occur between the overall adjustment capability amount and the adjustment amount that is adjusted when the power amount is actually adjusted.
