(Overview of the entire system)
FIG. 1 is a diagram showing a configuration of a power consumption management system according to an embodiment of the present invention.

  Referring to FIG. 1, a power consumption management system 201 according to an embodiment of the present invention includes a power company server 101, a power consumption management device 102, and a plurality of customer devices 151.

  The power company server 101 is operated by a power company on the power supply side, and transmits power management information related to power consumption to the power consumption management apparatus 102. This power management information is information indicating a period in which a tight supply and demand of power is expected, information on electricity charges by day or time, information indicating a power saving request, and the like.

  The consumer device 151 is provided in a power demand facility such as a building, factory, or home that receives power from an electric power company. The consumer device 151 is a device used in a system such as a BEMS (Building Energy Management System) or a HEMS (Home Energy Management System) for reducing power consumption by controlling the operation of electrical equipment in a power demand facility. Yes, for example, it is introduced by an operator called a BEMS aggregator.

  The power consumption management device 102 centrally manages power consumption in a plurality of power demanding facilities by communicating with a plurality of customer devices 151. Specifically, when the power consumption management apparatus 102 receives the power management information from the power company server 101, the instruction to notify the one or more customer apparatuses 151 of the instruction information regarding power consumption based on the received power management information. Process.

  For example, the power consumption management apparatus 102 sets a power saving period in which power consumption should be suppressed, a power saving target indicating the amount of power to be suppressed, and the like based on the received power management information, and the set power saving period and power saving target. Is sent to one or a plurality of customer devices 151.

  In addition, the power consumption management device 102 monitors the power consumption in each customer device 151 that has notified the instruction information, and changes the content of the instruction processing based on the monitoring result. For example, when the power consumption management apparatus 102 continuously monitors the power consumption by each customer apparatus 151 during the power saving period and determines that the power saving target cannot be achieved, one or more new instruction information is provided. To the consumer device 151. The instruction information newly notified based on the monitoring result is hereinafter referred to as “addition instruction information”.

(Specific example 1)
FIG. 2 is a diagram illustrating an example of instruction processing by the power consumption management device of the power consumption management system according to the embodiment of the present invention.

  Referring to FIG. 2, it is assumed that power consumption management system 201 includes customer apparatuses 151A, 151B, 151C, and 151D.

  First, the power consumption management apparatus 102 receives, from the power company server 101, power management information indicating that power supply / demand tightness is predicted in a period from time t1 to time t2.

  Next, the power consumption management apparatus 102 selects one or a plurality of consumer apparatuses 151 as the notification destination of the instruction information from the consumer apparatuses 151A, 151B, 151C, and 151D. Here, the power consumption management apparatus 102 selects the three consumer apparatuses 151 of the consumer apparatuses 151A, 151B, and 151C.

  Moreover, the power consumption management apparatus 102 has selected the period from the time t1 to the time t2 as the notification destination of instruction information, for example, in order to reduce the burden of each power demand facility by suppression of the power consumption over a long period of time. The number of home devices 151 is divided into three sub power saving periods. Then, the power consumption management apparatus 102 assigns each divided sub power saving period to each consumer apparatus 151 selected as a notification destination of instruction information.

  For example, the power consumption management apparatus 102 divides the period from time t1 to time t2 into a plurality of sub power saving periods divided at predetermined time intervals, and uses each divided sub power saving period as a notification destination of instruction information. The structure allocated to each selected consumer apparatus 151 may be sufficient.

  Here, the power consumption management apparatus 102 divides the period from time t1 to time t2 into three sub power saving periods of period A, period B, and period C, assigns period A to the consumer apparatus 151A, and sets period B Is assigned to the consumer device 151B, and the period C is assigned to the consumer device 151C.

  Next, the power consumption management apparatus 102 sets power saving targets Ga, Gb, and Gc in each sub power saving period, notifies the power saving request indicating the period A and the power saving target Ga to the consumer apparatus 151A as instruction information, and sets the period B In addition, a power saving request indicating the power saving target Gb is notified to the consumer device 151B as instruction information, and a power saving request indicating the period C and the power saving target Gc is notified to the consumer device 151C as instruction information.

  Next, in the period from time t1 to time t2, the consumer devices 151A, 151B, and 151C control the operation of the electrical equipment of the power demand facility in which they are provided according to the instruction information received from the power consumption management device 102. To do. For example, the consumer devices 151A, 151B, and 151C reduce power consumption by performing control such as increasing the set temperature of air conditioning.

  Thus, during the period from time t1 to time t2, the total power consumption (solid line graph in FIG. 2) in the power demand facility provided with the customer apparatuses 151A, 151B, 151C, 151D is the power consumption management. Compared to the total power consumption (dashed line graph in FIG. 2) in the case where it is assumed that the instruction processing by the device 102 has not been performed, the power consumption decreases.

(Specific example 2)
FIG. 3 is a diagram showing an example of instruction processing by the power consumption management apparatus of the power consumption management system according to the embodiment of the present invention.

  Referring to FIG. 3, here, similarly to the case shown in FIG. 2, the power consumption management apparatus 102 notifies the customer apparatus 151 </ b> A of the power saving request indicating the period A and the power saving target Ga as instruction information, and the period B And an instruction process of notifying the consumer device 151B of the power saving request indicating the power saving target Gb as instruction information and notifying the consumer device 151C of the power saving request indicating the period C and the power saving target Gc as instruction information before the time t1. To do.

  Next, it becomes difficult for the power demand facility provided with the consumer apparatus 151B to suppress power consumption according to the instruction information in the period B, and the power consumption management apparatus 102 performs the period B at the timing t3. It is determined that the power saving target Gb is not achieved.

  And the power consumption management apparatus 102 changes the content of the instruction | indication process performed before the time t1, for example, a consumer apparatus is set by using the power-saving request | requirement which shows the period from the timing t3 to the end of the period B as additional instruction information. 151D is notified. And consumer apparatus 151D controls operation | movement of the electric equipment in the electric power demand facility in which self is provided according to the instruction information received from the power consumption management apparatus 102. FIG.

  Thereby, power consumption is suppressed by the consumer device 151A in the period A, power consumption by the consumer device 151B and the consumer device 151D is suppressed in the period B, and power consumption is suppressed by the consumer device 151C in the period C. .

  As a result, during the period from time t1 to time t2, the total power consumption (solid line graph at the bottom of FIG. 3) in the power demand facilities provided with the customer apparatuses 151A, 151B, 151C, and 151D is the power consumption management. This is reduced compared to the total power consumption (dashed line graph in FIG. 3) when it is assumed that the instruction processing by the device 102 has not been performed.

  Note that the power consumption management apparatus 102 may select the consumer apparatus 151 that is the notification destination of the additional instruction information from the consumer apparatuses 151 other than the consumer apparatus 151 that has already notified the instruction information. You may select the consumer apparatus 151 used as the notification destination of additional instruction information from the consumer apparatuses 151 containing the consumer apparatus 151 which notified instruction information.

  That is, in the example described above, the power consumption management apparatus 102 has selected the consumer apparatus 151D other than the consumer apparatuses 151A, 151B, and 151C that have already notified the instruction information as the notification destination of the additional instruction information. As the notification destination, any one of the customer apparatuses 151A, 151B, 151C may be selected.

In addition, the instruction unit 12 sets a power saving target in each sub power saving period. And the instruction | indication part 12 notifies instruction | indication information which shows the allocated sub power-saving period and the set power-saving target to each consumer apparatus 151 selected as a notification destination of instruction information. Note that the instruction unit 12 may assign a plurality of sub power saving periods to one consumer device 151. Further, among the consumer devices 151 selected as the notification destination of the instruction information, there may be a consumer device 151 to which no sub power saving period is assigned.

  The reference information acquisition unit 14 receives, from the power company server 101, reference power consumption information that is a reference for power consumption in each power demand facility. The reference power consumption information indicates, for example, a baseline (hereinafter simply referred to as “reference value”) that is calculated by the power company server 101 based on past data and serves as a reference for the power consumption of the power demand facility. . Then, the reference information acquisition unit 14 outputs the received reference power consumption information to the monitoring unit 13.

  The monitoring unit 13 receives, from the instruction unit 12, information indicating each sub power saving period assigned to one or a plurality of customer devices 151 by the instruction unit 12 and a power saving target in each sub power saving period. Moreover, the monitoring part 13 receives the power consumption information in a corresponding power demand facility from each consumer apparatus 151 included in the power consumption management system 201 at a predetermined interval, for example.

Continue monitoring. When the monitoring unit 13 determines that the power saving target cannot be achieved, the monitoring unit 13 outputs a request for changing the content of the instruction process to the instruction unit 12.

  When the instruction unit 12 receives a request for changing the content of the instruction process from the monitoring unit 13, the instruction unit 12 acquires the selection information stored in the storage unit 15 via the selection information acquisition unit 17. This selection information is information used when selecting a notification destination of additional instruction information. For example, the selection information is timing information indicating the notification timing of past instruction information to each consumer device 151.

  Then, the instruction unit 12 selects a notification destination of the additional instruction information using the priority information received from the priority information acquisition unit 16 and the selection information received from the selection information acquisition unit 17. For example, the instruction unit 12 uses the customer device 151 having the oldest notification timing of the past instruction information as the notification destination of the additional instruction information from among the plurality of customer devices 151 to which the priority “2” is given. select.

  And the instruction | indication part 12 sets newly the power-saving period and power-saving target requested | required of the said consumer apparatus 151 selected as the notification destination of additional instruction information, and adds the power-saving request | requirement which shows the set power-saving period and power-saving target. The information is notified to the consumer device 151 as information. The power saving period and the power saving target indicated by the additional instruction information may be the same as the power saving period and the power saving target indicated by the already notified instruction information.

  Next, according to the instruction information received from the power consumption management device 102, the consumer device 151A controls the operation of the electrical equipment in the power demand facility in which the customer device 151A is provided so that the power saving target Ga is satisfied in the period A. (Step S17).

  Further, the consumer device 151B controls the operation of the electrical equipment in the power demand facility in which the customer device 151B is provided so that the power saving target Gb is satisfied in the period B according to the instruction information received from the power consumption management device 102 ( Step S18).

  Further, according to the instruction information received from the power consumption management device 102, the consumer device 151C controls the operation of the electrical equipment in the power demand facility in which the customer device 151C is provided so that the power saving target Gb is satisfied in the period C ( Step S19).

  In addition, the power consumption management apparatus 102 repeatedly receives power consumption information in the corresponding power demand facility from each consumer apparatus 151 from period A to period C, and based on the received power consumption information, each sub power saving period Monitoring processing is performed to continuously monitor whether or not the power saving target can be achieved.

  For example, the power consumption management apparatus 102 receives from the power company server 101 reference power consumption information that is a reference for power consumption in each power demand facility. Then, the power consumption management device 102 compares the received reference power consumption information with the power consumption information received from each consumer device 151 to determine whether or not the power saving target can be achieved in each sub power saving period. Determine whether.

  If the power consumption management apparatus 102 determines that the power saving target cannot be achieved as a result of the monitoring process, the power consumption management apparatus 102 notifies the customer apparatus 151D of additional instruction information, for example. And consumer apparatus 151D controls operation | movement of the electric equipment in the electric power demand facility in which it is provided according to the instruction information received from the power consumption management apparatus 102 (step S20).

(Details of monitoring processing)
FIG. 7 is a flowchart showing a detailed operation procedure of the monitoring process shown in FIG.

  Referring to FIG. 7, first, the power consumption management apparatus 102 receives power consumption information in a corresponding power demand facility from each customer apparatus 151 included in the power consumption management system 201, for example, every 15 minutes ( Step S21).

  Next, the power consumption management apparatus 102 receives the reference power consumption information indicating the reference value of the power consumption of the power demand facility during the power saving period from the power company server 101 (step S22).

  Next, for example, every time power consumption management apparatus 102 receives power consumption information from consumer apparatus 151, power consumption management apparatus 102 calculates the difference between the power consumption indicated in the power consumption information and the reference value. And the power consumption management apparatus 102 acquires the calculated value as the electric energy (henceforth "the suppression actual amount") which the said consumer apparatus 151 was able to suppress (step S23).

  Next, the power consumption management apparatus 102 determines whether or not the power saving target can be achieved by comparing the calculated actual amount of suppression with the power saving target in the power saving period.

  For example, when the power consumption management device 102 indicates the amount of power to be suppressed, the power consumption management apparatus 102 calculates the amount of power to be suppressed indicated in the power saving target and the calculated amount of suppression to be suppressed every time the amount of suppression is calculated. Difference D1 (= (amount of power to be suppressed indicated in the power saving target) − (actual suppression amount)) is calculated. Then, when the state where the calculated difference D1 is equal to or greater than the threshold Th continues for a predetermined time or longer, the power consumption management apparatus 102 determines that the power saving target cannot be achieved. On the other hand, when the state where the calculated difference D1 is equal to or greater than the threshold Th does not continue for a predetermined time or more, the power consumption management apparatus 102 determines that the power saving target can be achieved (step S24).

  When the power consumption management device 102 determines that the power saving target can be achieved (“Yes” in step S24), the power consumption information transmitted from each consumer device 151 included in the power consumption management system 201. Is continuously received (step S21).

  On the other hand, when it is determined that the power saving target cannot be achieved (“No” in step S24), the power consumption management apparatus 102 changes the content of the instruction process.

  Specifically, the power consumption management apparatus 102 uses the priority information and the selection information to select the consumer apparatus 151 that is the notification destination of the additional instruction information (Step S25).

  Then, for example, the power consumption management apparatus 102 newly sets a power saving period and a power saving target so that the total amount of actual records of suppression for each consumer device 151 exceeds the power saving target (step S26). Then, the power consumption management device 102 notifies the selected consumer device 151 of additional instruction information indicating the newly set power saving period and power saving target (step S27).

  Then, the power consumption management apparatus 102 repeats the above-described operation until, for example, a period during which the tightness of power supply and demand indicated in the power management information is predicted ends.

(Reference value calculation process)
FIG. 8 is a diagram showing an example of a table used for calculating a reference value by the power company server of the power consumption management system according to the embodiment of the present invention.

  Referring to FIG. 8, power company server 101 measures the power consumption of past power demand facilities every hour, and stores the measured value in table T1.

  For example, the table T1 includes the power consumption of the power demand facility at 13:00 to 14:00 on October 6, October 7, October 8, October 9, October 10, 2013. It is stored that the amounts are 100 kWh, 90 kWh, 95 kWh, 120 kWh, and 100 kWh, respectively.

  In addition, the table T1 includes the total daily power consumption of the power demand facilities in October 6, 2013, October 7, October 8, October 9, and October 10, 2013. Are 1200 kWh, 950 kWh, 1100 kWh, 1500 kWh, and 1100 kWh.

  For example, the power company server 101 calculates a reference value for the target date based on data for five days immediately before the target date on which tightness of power supply and demand is predicted. That is, if it is predicted that the power supply and demand will be tightened from 13:00 to 14:00 on October 11, 2013, the power company server 101 has five days from October 6 to October 10, 2013. Based on this data, a reference value for 13:00 to 14:00 on October 11, 2013 is calculated.

  Specifically, for each day from October 6 to October 10, 2013, the power company server 101 uses the power consumption of the power demand facility from 13:00 to 14:00, that is, October 6 “100 kWh”, October 7 “90 kWh”, October 8 “95 kWh”, October 9 “120 kWh” and October 10 “100 kWh”, and the average of these extracted values (= (100 + 90 + 95 + 120 + 100) / 5 = 101 kWh) is calculated. Then, the electric power company server 101 sets the calculated value as a reference value for 13:00 to 14:00 on October 11, 2013.

  As described above, the power company server 101 calculates the power consumption reference value in the power saving period based on the past data, and transmits the calculated reference value to the power consumption management apparatus 102.

  The power company server 101 may calculate the reference value based on the data of the power consumption by all the power demanding facilities whose power consumption is managed by the power consumption management apparatus 102, or the power consumption management apparatus 102 may The reference value may be calculated based on power consumption data of some of the power demanding facilities whose power consumption is managed.

  In addition, the power company server 101 may calculate the reference value by using other calculation methods as well as the above calculation method.

  For example, the electric power company server 101 specifies the day with the largest total daily power consumption among the five days immediately before the target date on which the tightness of power supply and demand is predicted. Then, assuming that the time zone in which power supply and demand is tight is predicted to be from 13:00 to 14:00, the power company server 101 calculates the power consumption at 13:00 to 14:00 on the specified day from 13:00 on the target day. The reference value at 14:00 can be used.

  Further, as another calculation method, for example, the power company server 101 excludes one day in which the variance of power consumption for each hour is the largest among the five days immediately before the target date on which the tightness of power supply and demand is predicted. Then, assuming that the time period in which the tightness of power supply and demand is predicted is from 13:00 to 14:00, the power company server 101 covers the remaining four days, and the power consumption of the power demand facility at 13:00 to 14:00. The average of is calculated. And the electric power company server 101 can make the calculated value the reference value in 13:00 to 14:00 on a target day.

  The power company server 101 is not limited to the configuration in which the reference value is calculated. For example, the power consumption management apparatus 102 may be configured to calculate the reference value using the various calculation methods as described above.

(How to select the notification destination for additional instruction information)
Next, a specific method for selecting a notification destination of additional instruction information by the power consumption management apparatus 102 will be described.

(I) Specific example 1
The power consumption management apparatus 102 stores timing information indicating the notification timing of past instruction information for some or all of the consumer apparatuses 151 included in the power consumption management system 201, for example, as selection information. In this case, the selection information acquisition unit 17 of the power consumption management apparatus 102 functions as a timing information acquisition unit.

  When the power consumption management apparatus 102 selects the notification destination of the additional instruction information, for example, among the plurality of consumer apparatuses 151 given the priority “2”, the consumer apparatus 151 with the old notification timing is added. Select preferentially as a notification destination of instruction information.

(Ii) Specific example 2
In addition, the power consumption management device 102 selects, as selection information, for example, a contract power amount contracted with an electric power company for some or all of the customer devices 151 included in the power consumption management system 201, or Each customer device 151 stores power amount information indicating the amount of power supplied from the power company. In this case, the selection information acquisition unit 17 of the power consumption management apparatus 102 functions as a power amount information acquisition unit.

  When the power consumption management apparatus 102 selects the notification destination of the additional instruction information, for example, among the plurality of customer apparatuses 151 to which the priority “2” is given, the demand with the large contract power amount or the supplied power amount The home device 151 is preferentially selected as the notification destination of the additional instruction information.

(Iii) Specific example 3
Moreover, the power consumption management apparatus 102, for example, as the selection information, when the instruction information is notified to the consumer apparatus 151 in the past, the control content of the operation of the electrical equipment by the consumer apparatus 151, the corresponding power demand facility Power consumption, weather information, event information, etc.

  FIG. 9 is an example of a table that includes the control contents of the operation of the electrical device by the consumer device that has notified the instruction information in the past, stored in the power consumption management device of the power consumption management system according to the embodiment of the present invention. FIG. Moreover, FIG. 10 is a figure which shows an example of the table containing the event information of each power demand facility memorize | stored in the power consumption management apparatus of the power consumption management system which concerns on embodiment of this invention.

  Referring to FIG. 9, the power consumption management apparatus 102 includes the consumer device 151 that has notified the instruction information in the past, the date and time when the instruction information is notified, and the electrical equipment of the consumer device 151 that has received the notification of the instruction information. Stores a table T2 including a plurality of entries in which the control contents, the power consumption in the corresponding power demand facility when the control contents are performed, and the weather information and event information when the instruction information is notified are associated with each other .

  Referring to FIG. 10, the power consumption management apparatus 102 stores a table T3 including event information that is scheduled to be performed at each power demand facility.

  The power consumption management apparatus 102 refers to the table T3 and confirms event information of each power demand facility during the power saving period. Further, the power consumption management apparatus 102 acquires weather information such as a weather forecast for the power saving period via the Internet or the like.

  For example, assuming that 13:00 to 14:00 on October 11, 2013 is a power saving period, the power consumption management apparatus 102 refers to the table T3 and uses the consumer at 13:00 to 14:00 on October 11, 2013. It is confirmed that the event “none” occurs at the power demand facility where the device 151A is provided, and the event “whole meeting” is scheduled to be performed at the power demand facility where the customer device 151B is provided. In addition, the power consumption management apparatus 102 acquires information indicating the temperature “32 ° C.”, the humidity “80%”, and the weather “sunny” from 13:00 to 14:00 on October 11, 2013 based on the weather forecast and the like. To do.

  Further, the power consumption management apparatus 102 refers to the table T2 shown in FIG. 9, for example, for each of the customer apparatuses 151A and 151B, from among a plurality of entries included in the table T2, weather and events in the power saving period Select one or more entries that contain the same or similar weather and events.

  For example, the power consumption management apparatus 102 selects the entry “A1” and the entry “A2” from the entries “A1”, “A2”, and “A3” included in the table T2 for the consumer apparatus 151A. For example, the power consumption management apparatus 102 selects the entry “B1” and the entry “B2” from the entries “B1”, “B2”, and “B3” included in the table T2 for the customer apparatus 151B. .

  Then, the power consumption management apparatus 102 selects one entry (hereinafter referred to as “optimum entry”) in which the weather and the event are most similar to the weather and the event in the power saving period among the selected entries. Select every 151.

That is, the power consumption management apparatus 102 sets the temperature during the power saving period to “Tpredict”, sets the temperature included in the selected entry to “Tpast”, sets the humidity during the power saving period as “Hpredict”, and sets the humidity included in the selected entry to Assuming that “Hpast”, the entry with the smallest difference D2 in the following expression is selected as the optimum entry.
D2 = (Tpredict−Tpast) × W1 + (Hpredict−Hpast) × W2 + Event

  In the above formula, “Event” is a negative value when the event in the power saving period and the event included in the selected entry match, and the event in the power saving period and the event included in the selected entry. If does not match, it is a positive value. Further, “W1” and “W2” are constants used for weighting.

  For example, when the power consumption management apparatus 102 selects the entry “A2” as the optimum entry, when the consumer apparatus 151A receives notification of instruction information from 13:00 to 14:00 on October 11, 2013, the consumer apparatus 151A Can be presumed to be highly likely to carry out control to increase the set temperature of the air conditioning by 1 ° C. Then, the power consumption management device 102 estimates that the power consumption of the power demand facility in which the consumer device 151A is provided is likely to be “100 kWh” by the consumer device 151A performing such control. can do.

  For example, when the power consumption management apparatus 102 selects the entry “B2” as the optimum entry, when the consumer apparatus 151B receives notification of instruction information at 13:00 to 14:00 on October 11, 2013, the demand information It can be estimated that the house device 151B is highly likely to perform control for increasing the set temperature of the air conditioning by 2 ° C. Then, the power consumption management apparatus 102 has a high possibility that the power consumption of the power demand facility in which the consumer apparatus 151B is provided will be “50 kWh” by the consumer apparatus 151B performing such control. Can be guessed.

  Then, the power consumption management apparatus 102 receives the reference power consumption information from the power company server 101, and calculates the difference between the reference value in the power saving period indicated in the received reference power consumption information and the power consumption included in the optimum entry. It is calculated as the amount of power estimated to be able to be suppressed (hereinafter referred to as “amount that can be suppressed”). Note that the power consumption management apparatus 102 calculates the suppression possible amount as described above for some or all of the customer apparatuses 151 included in the power consumption management system 201.

  When the power consumption management apparatus 102 selects the notification destination of the additional instruction information, for example, among the plurality of consumer apparatuses 151 to which the priority “2” is given, the consumer apparatus 151 having a large suppression amount is selected. Select preferentially as a notification destination of additional instruction information.

  Note that the power consumption management apparatus 102 may be configured to predict power consumption during a power saving period in each power demand facility using a technique such as a neutral network or autoregressive analysis. In this case, the power consumption management apparatus 102 can calculate the difference between the predicted power consumption (hereinafter referred to as “predicted value”) and the power consumption included in the optimum entry as a controllable amount.

(Iv) Specific Example 4
Moreover, the power consumption management apparatus 102 acquires the predicted value in a power-saving period about some or all the customer apparatuses 151 contained in the power consumption management system 201 as selection information, for example. In this case, the selection information acquisition unit 17 of the power consumption management apparatus 102 functions as a predicted value acquisition unit.

  Then, when the power consumption management apparatus 102 calculates the difference D3 between the acquired predicted value and the reference value in the power saving period and selects the notification destination of the additional instruction information, for example, the priority “2” is given. Among the plurality of customer devices 151, the customer device 151 having a large calculated difference D3 is preferentially selected as the notification destination of the additional instruction information.

(V) Specific Example 5
Moreover, the power consumption management apparatus 102 acquires the information which shows the power supply amount for the last N hours about the one part or all the customer apparatuses 151 contained in the power consumption management system 201 as selection information, for example. When the power consumption management apparatus 102 calculates a difference D4 between the acquired power supply amount for the previous N hours and the reference value for the previous N hours, and selects a notification destination of additional instruction information, for example, Among the plurality of customer devices 151 to which the priority “2” is given, the customer device 151 having a large calculated difference D4 is preferentially selected as the notification destination of the additional instruction information.

  Note that the power consumption management apparatus 102 is not limited to any one of the above-described specific examples 1 to 5, but, for example, any two or more of the methods from the specific examples 1 to 5 may be used. A notification destination of additional instruction information may be selected by combining methods.

  Further, in the above-described methods from the first specific example to the fifth specific example, the customer apparatus 151 that is the notification destination of the additional instruction information is selected from the customer apparatuses 151 given the priority “2”. For example, the notification destination of the additional instruction information may be selected from the customer apparatuses 151 to which the priority “1” is given.

  In addition, the power consumption management apparatus 102 may select the consumer apparatus 151 that is the notification destination of the instruction information to be notified before the selection period, using the method from the first specific example to the fifth specific example.
