The power management system 1 illustrated in FIG. 1 includes an area management server 100, a plurality of customers 20-1 to 20-14, a plurality of customers 30-1 to 30-14, and a wide area network NW. The power management system 1 corresponds to a power management system called a Town Energy Management System (TEMS) or a Community Energy Management System (CEMS). The power management system 1 manages the demand (consumption), power generation, storage of electricity, etc. of a plurality of consumers in a certain town or region. The area management server 100, the plurality of customers 20-1 to 20-14, and the customers 30-1 to 30-14 are connected via the wide area network NW, and transmit and receive predetermined information. In this case, the area management server 100 is connected to the wide area network NW via the communication line 501. The plurality of customers 20-1 to 20-14 and the customers 30-1 to 30-14 are connected to the wide area network NW via the communication line 500.

  In the present application, the customers 20-1 to 20-14 and the customers 30-1 to 30-14 mean equipment managed by a consumer (or a contractor) of the power receiving the supply of the grid power. The customers 20-1 to 20-14 and the customers 30-1 to 30-14 are not shown in the drawing for processing information used when managing the demand for power, power generation, storage of electricity, etc. A computer is provided, and the computer has a function of processing predetermined information and transmitting / receiving predetermined information to / from the area management server 100 or the like.

  The customers 20-1 to 20-14 and the customers 30-1 to 30-14 are customers managed by the area management server 100. The customers 20-1 to 20-14 and the customers 30-1 to 30-14 consume power in units of one or more single-family homes or multi-family dwellings, commercial / industrial facilities, public facilities, etc. Is a facility managed by the consumer. The customers 20-1 to 20-14 indicated by white circles in FIG. 1 are customers equipped with at least one of a storage facility or a power generation facility. The customers 30-1 to 30-14 shown by black circles are customers not equipped with either the power storage facility or the power generation facility.

  The regional management server 100 collects information such as the demand and supply status of the grid power, the demand and supply status of the power among the consumers 20-1 to 20-14 and 30-1 to 30-14, and the consumers 20-1 to 20-14. While performing the demand forecasting, the power generation forecasting, and the charge / discharge plan creation in the above, the demand forecasting of the consumers 30-1 to 30-14 is performed. At this time, the regional management server 100 classifies the customers in the region into one or more demand groups and flexible groups, and executes various calculations for each group.

  The demand group is a group of customers who have only equipment that consumes power. That is, the demand group is a group consisting of customers who do not have the possibility of adapting their own generated power or stored power to other customers. However, the demand group may include customers who have facilities for generating or storing power but do not want to accommodate the power to other customers.

  On the other hand, the accommodation group is a group consisting of consumers equipped with one or both of facilities for generating or storing power. That is, the accommodation group is a group consisting of customers who have the possibility of being able to adapt the self-generated power or stored power to other customers.

  In the example shown in FIG. 1, the customers 20-1 to 20-13 are classified into accommodation group (1) 200-1. The customer 20-14 is classified into the flexible group (2) 200-2. The consumers 30-1 to 30-11 are classified into the demand group (1) 300-1. Then, the consumers 30-12 to 30-14 are classified into the demand group (2) 300-2. In the following, when simply referring to an accommodation group without a code, accommodation group (1) 200-1 and accommodation group (2) 200-2 shall be included. Similarly, in the case of simply referring to a demand group without a code, it is assumed that the demand group (1) 300-1 and the demand group (2) 300-2 are included.

  Next, a configuration example of connection of power distribution lines to the customers 20-1 to 20-14 and the customers 30-1 to 30-14 shown in FIG. 1 will be described with reference to FIG. In the configuration example shown in FIG. 4, all the customers 20-1 to 20-14 and the customers 30-1 to 30-14 receive power supply from one distribution substation 601. The customers 20-14 and the customers 30-12 to 30-14 receive power at 6600 V directly from the high voltage distribution line 700 connected to the output of the distribution substation 601. Pole transformers 611 to 614 are connected to the high voltage distribution line 700. The customers 20-1 to 20-4 and the customers 30-1 to 30-2 receive the output of the distribution substation 601 at 200 V or 100 V via the pole transformer 611 and the low voltage distribution line 801. The consumers 20-5 to 20-8 receive the output of the distribution substation 601 at 200 V or 100 V via the pole transformer 612 and the low voltage distribution line 802. The customers 20-9 to 20-13 receive the output of the distribution substation 601 at 200 V or 100 V via the pole transformer 613 and the low voltage distribution line 803. Then, the customers 30-3 to 30-11 receive the output of the distribution substation 601 at 200 V or 100 V via the pole transformer 614 and the low voltage distribution line 804.

  In addition, each installation shown in FIG. 4 has the following specifications, for example. The installed capacity of the distribution substation 601 is about 20 MVA. The capacity of the feeder of the high voltage distribution line 700 is about 2 MVA (6600 V). The customers 20-14 and 30-12 to 30-14 receive power directly from the feeders and convert voltages with a private transformer. The installed capacity of the pole transformers 611 to 614 is about 100 kVA (200 V). The installed capacity of the customers 20-1 to 20-13 and the customers 30-1 to 30-11 is about 5 to 20 kVA.

Then, a customer 20-14 who receives power from the distribution substation 601 via the high voltage distribution line 700 without via the pole transformer belongs to the accommodation group (2) 200-2.

  Further, among the customers 30-1 to 30-14 belonging to the demand group, the customers 30-1 to 30 receiving power from the distribution substation 601 via the pole transformer 611 or 614 and the low voltage distribution line 801 or 804. 11 belongs to demand group (1) 300-1. Then, consumers 30-12 to 30-14, which receive power from the power distribution substation 601 via the high voltage distribution line 700 without the pole transformer, belong to the demand group (2) 300-2.

  In the example shown in FIG. 7, those having similar power consumption tendencies are grouped together. This grouping is an example of grouping in which variation in predicted values within a group is considered to be small. For example, accommodation group (1) 200-1 and demand group (1) 300-1 are general households, and accommodation group (2) 200-1 and demand group (2) 300-2 are establishments. In this example, group (1) is an hourly charge, and group (2) is a flat rate contract, and grouping is performed using a charge system. In addition, power consumption patterns are similar in the group, and the prediction of consumption in the whole group is stable.

In addition, when the charge varies depending on the time zone, the power rate 144 includes information indicating the calculation basis for each time zone.

  The consumer information 145 is information that defines each consumer. An example of customer information 145 of one customer is shown in FIG. In the example shown in FIG. 27, the customer information 145 includes items of customer ID (identification information), position information, equipment information, and incidental information.

  The group information 146 is information representing identification information of a group to which each customer belongs. An example of the group information 146 is shown in FIG. In the example shown in FIG. 29, the group information 146 includes the customer IDs of the customers 20-1 to 20-14 and the customers 30-1 to 30-14 (in this case, the customer IDs are 20-1 to 20-. 14 and 30-1 to 30-14) are information that associates the group name to which they belong. The group information 146 is created by the accommodation plan unit 130 based on, for example, an instruction from a manager or the like, and can be arbitrarily (dynamically) changeable according to a predetermined rule.

  22, based on the information stored in received information storage unit 120 and the information stored in basic information storage unit 140, accommodation planning unit 130 performs planning according to the flow of FIGS. 9 to 14 described later. Power generation forecast, demand forecast and charge / discharge information of the storage battery (ie charge / discharge plan) is formulated for each of the customers 20-1 to 20-14 belonging to the concession group, and the demand forecast is demand 30 belonging to the demand group It is formulated for each of 1 to 30-14 and stored in the transmission information storage unit 150. However, the power generation forecast is not created for the customers who do not have the power generation facility 95, and the charge / discharge plan is not formulated for the customers who do not have the storage battery 94.

  Next, the transmission information storage unit 150 stores each piece of information created by the accommodation plan unit 130. In this example, the transmission information storage unit 150 includes the customer 20-1 to 20-14 and the customer 30-1 to 30-, the information indicating the plan information 151, the information indicating the power generation prediction 152, and the information indicating the demand prediction 153.

  The power generation prediction 152 is information indicating generated power at predetermined time intervals (one hour in this example) of the power generation facility 95 calculated in advance. Further, the demand forecast 153 is information indicating the power predicted to be consumed every predetermined time in the consumer. The accommodation planning unit 130 calculates the power generation prediction 152 based on, for example, the solar radiation information and the power generation facility information 142 acquired in advance. Further, the accommodation planning unit 130 calculates, for example, the power consumed in each customer at predetermined time intervals within the past one week, and calculates the average value of the calculated power as the demand forecast 153.

  The accommodation planning unit 130 derives a charge and discharge plan for each of the consumers 20-1 to 20-14 based on the power rate 144 and the power generation forecast 152 and the demand forecast 153. The charge and discharge plan is such that it is determined at predetermined time intervals whether the storage facility 94 performs charging, discharging, or stopping. Further, when there is a request from the power information provider such as a power provider or a power company, for example, to increase or decrease the demand power used by the consumer, the accommodation plan unit 130 controls, for example, the load 98 to consume power. The information indicating the instruction to increase or decrease at each predetermined time can be created as a demand plan. In the present embodiment, the plan information 151 is information indicating future instructions regarding charging and discharging of power, demand, and power generation, and is created for each predetermined time and for each customer. The contents of the plan information 151 may be called a plan below. The plan information 151 can include charge and discharge plans and demand plans.

  Next, the transmitting unit 160 uses, as distribution information, part or all of the plan information 151, the power generation prediction 152, and the demand prediction 153 of each customer stored in the transmission information storage unit 150, for example, as an accommodation group (1) It distributes to the said customers 20-1 to 20-14 which belong to 200-1 or accommodation group (2) 200-2. The distribution information transmitted by the transmission unit 160 is received by the home controller 96 described with reference to FIG. 5 and the like. Then, based on the distribution information received by the home controller 96, the storage device 94 and the like are controlled.

  Next, with reference to FIG. 23, a configuration example of the in-home controller 96 described with reference to FIG. 5 and the like will be described.

  FIG. 23 is a diagram showing a configuration of a home controller 96A which is an example of the home controller 96 described with reference to FIG. 5 and the like. The in-home controller 96A shown in FIG. 23 includes a communication interface (1) 961, a transmitting / receiving unit (1) 962, a control unit 963, a transmitting / receiving unit (2) 964, a communication interface (2) 965, and a data memory 966.

To provide.

  Hereinafter, an operation example of the area management server 100 illustrated in FIG. 1 will be described with reference to flowcharts illustrated in FIGS. 9 to 14 and the like. In this operation example, it is assumed that the customers 20-1 to 20-14 belonging to the accommodation group have a solar power generation system as the power generation facility 95.

  FIG. 9 is a flowchart showing the flow of processing executed when the area management server 100 creates one plan. In this operation example, the area management server 100 newly creates a plan, for example, every 24 hours. In this case, the process shown in FIG. 9 is newly started every 24 hours. In addition, the regional management server 100 sequentially adjusts the contents of the plan when it is necessary to make an adjustment due to a change in weather conditions, a change in charge, or the like. For example, the area management server 100 creates a plan from 13:00 of the previous day to 24:00 of the present day at 13:00 on the day before the planning day. The regional management server 100 transfers the plan from the current plan to the new plan when creating a new plan. A plurality of processes shown in FIG. 9 can be simultaneously executed.

  That is, the area management server 100 starts the process shown in FIG. 9 at a specified time on the previous day, for example, 13:00, creates a new plan, or starts the process of determining whether or not adjustment is necessary. When the process shown in FIG. 9 is started, the interchange planning unit 130 first creates a prediction plan of the interchange group (step S101). The details of step S101 will be described later with reference to FIGS.

  Next, the accommodation planning unit 130 creates a forecasting plan of the demand group (step S102). The details of this step S102 will be described later with reference to FIG.

  Next, the concession plan unit 130 determines whether it is necessary to adjust the plan (step S103). When a predetermined event such as a change in weather conditions or a change in charges occurs and the determination process of step S103 is performed for the first time after the process of step S101 and the process of step S102 are performed, the accommodation plan unit 130 adjusts the plan. Is determined to be necessary (step S103: Yes). On the other hand, when the predetermined event has not occurred, the accommodation plan unit 130 determines that the adjustment of the plan is not necessary (Step S103: No). When it is determined that the adjustment of the plan is not necessary (Step S103: No), the concession plan unit 130 repeatedly executes the determination process of Step S103 at a predetermined time interval.

  When it is determined in step S103 that the adjustment of the plan is necessary (step S103: Yes), the accommodation plan unit 130 creates an adjustment plan of the demand amount and the surplus amount (step S104). The details of step S104 will be described later with reference to FIG.

  Next, the concession planning unit 130 distributes the created plan to the customers 20-1 to 20-14 belonging to the concession group (step S105).

  Next, the accommodation plan unit 130 determines whether or not the created plan has been completed, that is, whether or not the period of the plan has been completed (step S106). If it has been completed (step S106: Yes), the accommodation planning unit 130 ends the process shown in FIG. If not completed (step S106: No), the accommodation plan unit 130 determines whether there is a new plan (step S107). If there is a new plan (step S107: Yes), the concession plan unit 130 ends the process shown in FIG. When there is no new plan (Step S107: No), the concession plan unit 130 returns to Step S103, and determines whether it is necessary to adjust the plan (Step S103).

  Next, the details of the process of step S101 of FIG. 9, that is, the details of the forecasting plan of the accommodation group will be described with reference to FIGS. FIG. 10 is a flowchart showing the process called in step S101 of FIG. FIG. 11 is a flow chart showing the process called in step S205 of FIG. FIG. 12 is a flowchart showing the process called in step S201 of FIG.

  When the concession planning unit 130 calls the processing of the forecasting plan of the concession group shown in FIG. 10 in step S101 of FIG. 9, first, the power generation amount, demand amount, surplus amount, and shortage amount per unit time for each customer Is executed (step S201). In step S201, the interchange planning unit 130 calls the process shown in FIG.

  In the process shown in FIG. 12, the concession planning unit 130 refers to the customer information 145 and the group information 146 stored in the basic information storage unit 140, and from the basic information storage unit 140, the customer IDs of all accommodation groups. Read out (step S401). Next, the concession planning unit 130 determines whether or not the processes of steps S403 to S405 have ended for all the consumers (step S402). When it is determined that the processing of all the consumers is not completed (step S402: No), the concession planning unit 130 predicts the power generation for each of the customers 20-1 to 20-14 (step S403), the demand forecast (step S404) And surplus prediction (step S405).

  In the process of power generation prediction (step S403), the concession plan unit 130 executes the following respective processes. (1) The accommodation planning unit 130 first acquires solar radiation data. The solar radiation data is a predicted value of the amount of solar radiation per hour. The interchange planning unit 130 acquires, for example, information indicating the sunshine duration of the weather forecast, determines the amount of solar radiation for each hour of the planning date based on the location information of the customer included in the customer information 145, and associates it with the customer. Stored in a predetermined storage unit. (2) Next, the interchange planning unit 130 reads out the power generation facility information 142 of the customer from the basic information storage unit 140. (3) Then, the concession planning unit 130 predicts the power generation amount for each time based on the solar radiation data acquired in (1) and the power generation facility information 142 read in (2), and generates power in association with the customer. The prediction information 152 is stored in the transmission information storage unit 150 as the prediction 152, and the process of the power generation prediction (step S403) is ended.

  Further, in the processing of the demand forecast (step S404), the concession planning unit 130 executes the following respective processing. (1) The interchange planning unit 130 first reads out the past demand data of the customer from the information indicating the power consumption 127 of the received information storage unit 120. The demand data is information representing the magnitude of power consumption per unit time associated with the date and time. (2) Then, the concession planning unit 130 predicts the amount of demand for each hour based on the demand data read in (1) and the information of weather forecast of the planned period, etc. And stores it in the transmission information storage unit 150, and ends the processing of the demand forecast (step S404).

  Then, in the process of the surplus prediction (step S405), the accommodation planning unit 130 executes the following respective processes. (1) First, the concession planning unit 130 calculates the difference between the power generation forecast for each time zone calculated in step S403 of the customer and the demand forecast for each time zone calculated in step S404. (2) Next, the accommodation planning unit 130 determines, for each time zone, whether or not the power generation amount prediction is larger than the demand amount prediction. When the power generation amount prediction is larger than the demand amount prediction, the accommodation planning unit 130 stores the value of the difference obtained in (1) as a surplus amount in a predetermined storage unit, and ends the process of the surplus prediction (step S405). In this case, the accommodation planning unit 130 sets the shortage amount of the time zone to zero. On the other hand, when the power generation amount prediction is not larger than the demand amount prediction, the accommodation planning unit 130 stores the value of the difference obtained in (1) as a shortage amount in a predetermined storage unit, and performs the process of surplus prediction (step S405). finish. In this case, the concession plan unit 130 sets the surplus amount of the time zone to zero. The process of (2) is executed for all the time in each time zone.

  On the other hand, in the process shown in FIG. 12, when it is determined that the process of all the consumers is completed in the determination process of step S402 (step S402: Yes), the concession planning unit 130 ends the process shown in FIG. . Here, the process of step S201 shown in FIG. 10 ends.

  Next, the concession planning unit 130 refers to the customer information 145 and the group information 146 in the basic information storage unit 140, and acquires the customer ID of the customer included in each group for each group (step S202 in FIG. 10). ).

  Next, the concession planning unit 130 determines whether the calculation of all the groups is completed, that is, whether the process of step S204 and the process of step S205 have been completed for all groups (step S203). When calculation of all groups is not completed (step S203: No), the concession planning unit 130 determines the power generation amount, demand amount, surplus amount, and shortage amount per unit time for each customer of the customers in the group. It totals (step S204). In the example of the customers and the grouping shown in FIG. 1, the accommodation planning unit 130 generates an amount of electricity generated per unit time of all the consumers 20-1 to 20-13 in the accommodation group (1) 200-1 and the demand. The amount, the surplus amount, and the shortage amount are summed up to form the tallying result of the flexible group (1) 200-1, and the power generation amount per unit time of the customer 20-14 in the flexible group (2) 200-2. The demand amount, the surplus amount, and the shortage amount are set as the aggregation results of the flexible group (2) 200-2.

  Next, the interchange planning unit 130 executes a process of creating a charge / discharge plan of the storage battery (step S205). In step S205, the interchange planning unit 130 calls the process shown in FIG. FIG. 11 shows charge and discharge plan creation processing of the storage battery called in step S205 of FIG. The charge / discharge plan creation process of the storage battery of FIG. 11 is executed based on the total value of the power generation amount, demand amount, surplus amount, and shortage amount for each group time tabulated in step S 204 of FIG. Be done.

  In the process shown in FIG. 11, the interchange planning unit 130 first sets the target charging power of the storage battery as the remaining amount of the previous day (step S301). That is, in step S301, the accommodation plan unit 130 sets the nighttime charge amount to 0 as an initial value.

  Next, the concession planning unit 130 allocates surplus power for each time zone, allocates charge to charge the storage battery until the storage battery is fully charged, and reduces the surplus power (step S302).

  Next, the concession planning unit 130 determines whether the total demand amount is larger than the storage battery capacity (that is, the storage battery storage amount or the remaining capacity) (step S303). If the total demand amount is larger than the storage battery capacity (step S303: Yes), the accommodation plan unit 130 sets a plan to allocate and discharge the storage battery capacity in the electricity bill level maximum time zone (step S304).

  Next, in FIG. 11, the accommodation planning unit 130 determines whether there is a remainder in the storage battery capacity (step S305). If there is a surplus in the storage battery capacity (step S305: Yes), the accommodation planning unit 130 sets a plan to allocate the discharge to the time zone of one lower level (step S306). Next, the concession planning unit 130 determines whether or not the discharge has been allocated to all the time zones (step S307). When not allocating to all the time slots (Step S307: No), accommodation plan part 130 performs judgment processing of Step S305 (Step S305).

  On the other hand, when the total demand amount is not larger than the storage battery capacity (step S303: No), the concession plan unit 130 sets a plan to allocate and discharge the storage battery capacity in the entire time zone (step S309).

  When it is determined in step S305 that there is no remainder in the storage battery capacity (step S305: No), when discharge is allocated to all time zones in step S307 (step S305: Yes), or the process of step S309 is completed. If so, the accommodation planning unit 130 creates a nighttime charge amount plan (step S308). The nighttime charging plan is a charging plan of a storage battery using power with the lowest nighttime charge level. The nighttime charge amount plan can be set according to, for example, the contents of the plan of discharge from the storage battery, the demand for increase in demand power, the presence or absence of the demand for decrease, and the amount.

  Next, the concession planning unit 130 performs a process of allocating the determined plan to the storage battery provided in each of the power storage facilities 94 of the consumers 20-1 to 20-14 (step S301). Here, the process of FIG. 11 ends, and the process of step S205 illustrated in FIG. 10 ends.

  Next, with reference to FIGS. 15 and 16, an example of creation of the concession group prediction plan in step S101 of FIG. 9 will be described. FIG. 15 shows a plan created for accommodation group (1) 200-1. FIG. 16 shows a plan created for accommodation group (2) 200-2.

  FIG. 15 shows an example of the processing result of step S101 of FIG. 9 with respect to accommodation group (1) 200-1. FIG. 15 shows the calculation results of the power generation amount, demand amount, discharge amount, charge amount, shortage amount, demand and remaining capacity of the flexible group (1) 200-1 per hour for 24 hours on the day of the planning date. Here, demand means the amount of power supplied to other consumers or the amount of demand for power supplied from other consumers. The power generation amount, the demand amount, the discharge amount, the charge amount, the shortage amount, and the demand are each an average value for one hour, and the unit is kW. The remaining capacity is an average of 1 hour of the percentage of the storage capacity to the rated capacity. However, the time change of the remaining capacity shown at the top of FIG. 15 is for showing the tendency of the time change of the remaining capacity, so that the value of 0 minutes of each time coincides with the average value of the remaining capacity. I draw a broken line. Therefore, values other than 0 minutes at each time do not necessarily match the predicted values.

  For example, predicted values or planned values from 0 o'clock to 1 o'clock 0 in FIG. 15 are respectively as follows. The predicted value of power generation is 0 kW. The forecasted demand is 10 kW. The planned value of the discharge amount is 0 kW. The planned value of the charge amount is 0 kW. The predicted value of the shortage is 10 kW. The predicted value of the surplus amount is 0 kW. The demand is 0 kW. And the predicted value of the remaining capacity is 0%. Also, for example, predicted values or planned values from 14:00 to 15:00 are as follows. The predicted value of power generation is 50 kW. The forecasted demand is 15 kW. The planned value of the discharge amount is 0 kW. The planned value of the charge amount is 20 kW. The predicted value of the shortage is 0 kW. The predicted amount of surplus is 15 kW. The demand is 0 kW. And the predicted value of the remaining capacity is 80%.

  FIG. 16 shows an example of the processing result of step S101 of FIG. 9 with respect to accommodation group (2) 200-2. FIG. 16 shows calculation results of the power generation amount, demand amount, discharge amount, charge amount, shortage amount, demand and remaining capacity of the accommodation group (2) 200-2 for one hour on the day of the planning day on the day of the planning day. In FIG. 16, each value of power generation, demand, discharge, charge, shortage, and demand is an average value for one hour, and the unit is kW. The remaining capacity is an average of 1 hour of the percentage of the storage capacity to the rated capacity. However, the time change of the remaining capacity shown at the top of FIG. 16 is for showing the tendency of the time change of the remaining capacity, so that the value of 0 minutes of each time coincides with the average value of the remaining capacity. I draw a broken line. Therefore, values other than 0 minutes at each time do not necessarily match the predicted values.

  For example, predicted values or planned values from 0 o'clock to 1 o'clock in FIG. 16 are as follows. The predicted value of power generation is 0 kW. The forecasted demand is 50 kW. The planned value of the discharge amount is 0 kW. The planned value of the charge amount is 0 kW. The predicted value of the shortage is 50 kW. The predicted value of the surplus amount is 0 kW. The demand is 0 kW. And the predicted value of the remaining capacity is 0%. Also, for example, predicted values or planned values from 14:00 to 15:00 are as follows. The predicted value of power generation is 50 kW. The forecasted demand is 95 kW. The planned value of the discharge amount is 0 kW. The planned value of the charge amount is 0 kW. The forecast value of the shortage is 45 kW. The predicted value of the surplus amount is 0 kW. The demand is 0 kW. And the predicted value of the remaining capacity is 65%.

  Next, the details of the process of step S102 of FIG. 9, that is, the details of the forecasting plan of the demand group will be described with reference to FIG. FIG. 13 is a flow chart showing the process called in step S102 of FIG.

  When calling plan processing of the demand group shown in FIG. 13 in step S 102 of FIG. 9, the concession planning unit 130 first makes the customer information 145 and the group information 146 stored in the basic information storage unit 140. The customer ID of all demand groups is read out from the basic information storage unit 140 by reference (step S801). Next, the concession planning unit 130 determines whether or not the processing of steps S803 to S804 has ended for all the consumers (step S802). When it is determined that the processing of all the consumers is not completed (step S802: No), the concession planning unit 130 stores the past demand data of the customers for each of the customers 30-1 to 30-14. It reads from the information which shows the power consumption 127 of the part 120 (step S803). Next, the concession planning unit 130 predicts the amount of demand for each hour based on the demand data read in step S 803 and the weather forecast information of the planned period, associates it with the customer, and stores it as transmission demand storage 153 as the demand forecast 153 The information is stored in the unit 150 (step S804). Next, the concession planning unit 130 executes the determination process of step S802 (step S802).

  On the other hand, when it is determined that the processing of all the consumers has been completed (step S802: Yes), the concession planning unit 130 refers to the customer information 145 and the group information 146 in the basic information storage unit 140, and The customer ID of the customer included in the group is acquired (step S805). Next, the concession planning unit 130 determines whether the calculation of all the groups is completed, that is, whether the process of step S807 is completed for all the groups (step S806). When calculation of all the groups is not completed (step S806: No), the concession planning unit 130 totals the demand amount per unit time for each customer of the customers in the group (step S807). In the example illustrated in FIG. 1, the concession planning unit 130 sums up the demand amounts per unit time of all the customers 30-1 to 30-11 in the demand group (1) 300-1 to obtain the demand group (1 Of the demand group (2) 300-2 by summing up the demand amounts per unit time of the customers 30-12 to 30-14 in the demand group (2) 300-2 as the aggregation result of 300-1). It will be the aggregation result.

  On the other hand, when it is determined in the determination processing of step S806 that the processing of all the groups is completed (step S806: Yes), the concession plan unit 130 sets the power exceeding the contracted power as the supply request demand (step S808). When the process of step S808 ends, the concession planning unit 130 ends the process illustrated in FIG. Here, the process of step S102 illustrated in FIG. 9 ends.

  Next, the details of the process of step S104 of FIG. 9, that is, the details of the adjustment plan of the demand amount and the surplus amount will be described with reference to FIG. FIG. 14 is a flowchart showing the process called in step S104 of FIG. In addition, in step S104 of FIG. 9, the interchange planning unit 130 recalculates and corrects the aggregation result for each group as necessary and repeats the processing of FIG. 14 based on the processing result of the processing shown in FIG. Run.

  In the process shown in FIG. 14, the accommodation planning unit 130 first aggregates the demand amount for each time unit for each charge level (step S901). Next, the concession planning unit 130 counts the surplus amount for each time unit for each charge level (step S902). Next, the accommodation planning unit 130 reads out the unprocessed highest demand (step S 903). Next, the accommodation planning unit 130 determines whether or not the allocation process for every unit time of all the surplus power (that is, the process of step S905) is completed (step S904).

  When the allocation process for every unit time of all the surplus power is not completed (step S904: No), the concession plan unit 130 allocates demand power (that is, the power for which supply is requested) in a time zone where there is surplus power. (Step S905). Details of the process of step S 905 will be described later. Next, the concession planning unit 130 reads an unprocessed demand with a high charge from the price of the surplus power (step S906), and then performs the determination process of step S904 (step S904).

  On the other hand, when the allocation process for every unit time of all surplus powers is completed (step S 904: Yes), the concession planning unit 130 determines whether the allocation of the unprocessed highest charge demand has been completed (step S S 907). If allocation of the unprocessed highest charge demand has not been completed (step S 907: No), the accommodation planning unit 130 determines whether there is a storage capacity in the corresponding time zone (step S 908). If there is a storage capacity in the corresponding time zone (step S 908: Yes), the accommodation planning unit 130 allocates the storage battery capacity to the demand (step S 909). After the process of step S909, the accommodation planning unit 130 performs the determination process of step S907 (step S907).

  On the other hand, when the allocation of the unprocessed highest charge demand has been completed in the determination process of step S 907 (step S 907: Yes), or when there is no storage capacity in the corresponding time zone in the determination process of step S 908 ( Step S907: No), the concession planning unit 130 ends the processing shown in FIG. Here, the process of step S104 illustrated in FIG. 9 ends.

  Next, with reference to FIGS. 17 to 21, in the process of step S905 in FIG. 14, the concession plan unit 130 selects the concession group (1) 200-1 and the concession group (2) 200 shown in FIG. 15 and FIG. An example will be described in which the surplus power predicted to be generated at −2 is allocated to the demand of the demand group. FIG. 17 shows an example of calculation results of adjustment of the demand amount and the surplus amount.

  In FIG. 17, the surplus amount 3101 and the remaining capacity 3108 correspond to the surplus amount and the remaining capacity of the accommodation group (1) 200-1 shown in FIG. As shown in FIG. 16, the surplus amount of the interchange group (2) 200-2 is 0 in the entire time zone. The demand (9) 3102 corresponds to the demand of the demand group (2) 300-2. The demand (1) 3105 corresponds to the demand of the demand group (1) 300-1. In this example, demand (3) 3103 and demand (2) 3104 are assumed to exist in addition to them. The remaining capacity 3107 corresponds to the remaining capacity of the accommodation group (2) 200-2 shown in FIG. In this example, since only the surplus power of the accommodation group (1) 200-1 is to be allocated, the total remaining capacity 3109 is the remaining capacity 3108 of the accommodation group (1) 200-1. However, the storage capacity of the accommodation group without surplus power can also be the target of allocation.

  Further, in the example shown in FIG. 17, it is assumed that the demand (9) 3102 which is the supply request demand of the demand group (2) 300-2 is the demand of the highest charge. In this case, the demand group (2) 300-2 is a flat rate contract as described above, and the demand (9) 3102 is a demand when the contracted power amount is exceeded. In addition, for the demand group (2) 300-2, the charge of the demand is set to be higher than other charges in the community according to a rule as shown in FIG. 21, for example. Therefore, the demand (9) 3102 is the top priority demand. In the present embodiment, the community means an area or a community to be managed by the area management server 100, and a plurality of groups to be managed by the area management server 100 belong to the position or the community in the area. There is. In the process of step S 905 in FIG. 14, the surplus amount of the accommodation group is allocated to the high priority demand. Further, in the example shown in FIG. 17, it is assumed that the priority according to the charge (or the content of the contract) is set for each demand. In this example, the priority of the demand (9) 3102 is the highest, followed by the demand (3) 3103, the demand (2) 3104, and the demand (1) 3105, and so on. In this case, the numbers in parentheses indicate the size of the charge level, and the demand with the higher level has higher priority.

  In the example shown in FIG. 17, the surplus power 3101 is surrounded by a thick line from 14:00 to 17:00 which is a surplus time zone. On the other hand, the demand (9) 3102 surrounded by a bold line is from 13:00 to 20:00 which is a demand time zone. That is, the surplus time zone and the demand time zone do not match. In such a case, in the process of step S 905 of FIG. 14, for example, allocation is performed in the following priority order.

  (1) High priority demand

  (2) Demand close to surplus generation time zone (forward priority)

  In this example, it is decided to allocate all the surplus power. That is, all of the total value 55 kW of the surplus power of the surplus time zone from 14:00 to 17:00 are allocated. At that time, when the surplus power time zone and the demand time zone do not match, the shift of the time zone can be compensated for by using charging and discharging of the storage battery. That is, with the result recalculated in step S905 in FIG. 14, the process of allocating to the storage battery in step S909 is subsequently performed. In the present example, when there is no surplus turning destination in the group, the purchased power from the grid is reduced, and it is processed as if the most expensive power was supplied in that time zone.

  In the example shown in FIG. 17, the surplus power is shown by the power from 13:00 to 20:00 shown by the bold line of the demand (9) 3102 and by the bold line of the demand (3) 3103. It is allocated to the power from 13:00 to 14:00. In this case, the determined demand total 3106 is 25 kW, 5 kW, 5 kW, 5 kW, 5 kW, 5 kW, and 5 kW of each time zone from 13:00 to 20: 00, which is indicated by a bold line.

  Further, in step S104 of FIG. 9 in which the process of FIG. 14 is called, the accommodation planning unit 130 recalculates and corrects the accommodation group plan (that is, the aggregation result for each group) based on the demand allocation result. FIG. 18 shows the result of recalculation of the plan for accommodation group (1) 200-1. FIG. 18 shows the result of replanning by allocating the demand total determined in FIG. 17 to the surplus power with respect to the calculation result of the plan shown in interchange group (1) 200-1 shown in FIG. As shown in FIG. 18, in re-planning, the concession planning unit 130 recalculates as consumption including the demand amount in addition to the demand in the concession group (1) 200-1. As shown in FIG. 18, as a result, the discharge plan of the storage battery is changed, and the surplus time zone and amount change.

  As described above, in the case of interchanging the power among the consumers, the time zone in which the power is desired to be supplied may not coincide with the time zone in which the surplus power is generated. In such a case, for example, charging / discharging of the power using a storage facility can absorb the time zone shift. However, when using a power storage facility, the predicted value of the surplus amount on the assumption of flexibility may differ from the predicted value of the surplus amount not on the assumption. For example, when the time zone for charging the storage facility changes, the size of the surplus amount and the generation time zone change. In such a case, it is necessary to recalculate the predicted value on the premise that it is flexible as needed.

  At this time, since surplus power is still generated in the time zone from 15:00 to 16:00 surrounded by a thick line, the accommodation plan unit 130 calls the process of FIG. 14 again, and assigns the second allocation. Do the processing.

  FIG. 19 shows the result of the second assignment process. Since the surplus plan at this time is 15 kw, the accommodation plan unit 130 assigns this to the highest level demand (3) among the remaining demand. In the first result of the recalculation shown in FIG. 18, surpluses are given at 15:00 and 16:00. Further, as shown in FIG. 19, the highest charge level of the demand is 3, and the closest time zone is 20 kw at 12 o'clock (that is, the time zone from 12 o'clock to 13 o'clock). Since the surplus is 15 kw, it will receive the demand of 15 kw of this.

  After the second allocation process, in step S104 of FIG. 9, the accommodation planning unit 130 recalculates and corrects the accommodation group plan based on the second allocation result of the demand. FIG. 20 shows the result of the second recalculation of accommodation group (1) 200-1. FIG. 20 shows the result of recalculating that the demand total added to the first calculation result determined in FIG. 17 is added to the demand in the group and consumed as the result of the second recalculation result shown in FIG. Indicates In the example shown in FIG. 20, as a result, the charge amount in the time zone of 12 o'clock decreases, the surplus power disappears, and the adjustment is completed. Above, the interchange planning unit 130 ends the calculation of step S104 of FIG. 9 and completes the plan of charging and discharging in the group. The accommodation plan unit 130 transmits the calculated discharge and charge plans to the target in-home controller 96 (step S105 in FIG. 9). On the other hand, the home controller 96 changes the control mode at a determined time. Examples of control modes are described above with reference to FIG.

  In the above description, the time unit is one hour, but may be, for example, 30 minutes or 10 minutes. Moreover, although the timing of a plan is adjusting as needed on a daily basis, it may be shorter, such as twice a day, for example.

  As described above, in the present embodiment, the accommodation planning unit 130 includes one or more accommodation groups consisting of one or more customers 20-1 to 20-14 including at least one of the power generation facility 95 or the storage facility 94. , Customer information 145, and information representing one or more demand groups consisting of one or more customers 30-1 to 30-14 having neither the power generation facility 95 nor the storage facility 94. With reference to the basic information storage unit 140 stored in combination with the information 146, demand forecasting, power generation forecasting and charge / discharge plan creation are performed for one or more customers 20-1 to 20-14 belonging to the concession group Demand forecast for one or more customers 30-1 to 30-2 belonging to the demand group, and each forecast result and the charge / discharge plan creation result To create a plan to interchange the surplus power generated is predicted at 1 or more flexible groups based on the result of the aggregation per group in one or more of demand groups. According to this configuration, when the customers 20-1 to 20-14 and the customers 30-1 to 30-14 are classified in advance into the flexible group and the demand group, and surplus power is calculated, power generation prediction and charging Discharge planning is limited to the customers 20-1 to 20-14 belonging to the flexible group. Therefore, the number of program steps should be reduced and the size of the required memory area should be reduced, compared to the case where power generation prediction and charge / discharge plan creation are basically performed for all groups. Becomes easy. That is, resources can be reduced, and a plan for exchanging power between a plurality of groups can be efficiently created.

  Further, in the present embodiment, the accommodation planning unit 130 is a accommodation plan for surplus power (that is, a plan for allocating surplus power to demand based on the calculation result of surplus power calculated again based on the creation result of the plan for accommodating surplus power). Recreate). According to this configuration, it is possible to easily improve the creation accuracy of the plan.

  Further, in the present embodiment, the concession planning unit 130 generates power generation forecasting, demand forecasting, charge / discharge plan creation, totaling for each concession group or demand group, and creation of a plan to accommodate surplus power, in units of predetermined time. I do. According to this configuration, the difference between the time zone of surplus power and the time zone of demand can be easily recognized, and adjustment using charging and discharging of the power storage facility can be performed with high accuracy.

FIG. 8 is a view showing an example of each grouping in the fourth embodiment. The grouping shown in FIG. 8 is grouping made on the basis of the feeders 701 to 703 of the high voltage distribution line 700 to which each customer is connected. That is, each group consists of consumers connected to the same feeder 701, 702 or 703 of the distribution network. In this case, the consumers 20-1 to 20-4 connected to the pole transformer 611 connected to the feeder 701 are classified into accommodation group (1) 200-1. Also, the customers 20-14 and the customers 20-5 to 20-13 connected to the feeder 702 directly or via the pole transformer 612 or the pole transformer 613 are classified into the flexible group (2) 200-2. It is done. Further, the customers 30-12 and the customers 30-1 to 30-2 connected to the feeder 701 directly or via a pole transformer 611 are classified into the demand group (1) 300-1. Also, the customers 30-13 to 30-14 and the customers 30-3 to 30-11 connected to the feeder 703 directly or via the pole transformer 614 are classified into the demand group (2) 300-2. There is.

  By grouping groups based on the feeders of the distribution network as shown in FIG. 8, it is possible to make a plan for flexibility so that the power flowing to the feeders does not exceed the upper limit.

  In addition, each above-mentioned embodiment can be made into the following aspects, for example. Alternatively, each embodiment described above can be understood as having the following aspect.

  That is, the power management system 1, 1A or 1B is a power management system that manages supply and consumption of power in the grid power supply, the storage battery, and the power load. Also, the power management system 1, 1A or 1B classifies the customers in the community into one or more demand groups and accommodation groups, estimates the supply and consumption of power on a predetermined day for each accommodation group, and as an estimation result Make a demand, charge and discharge plan including surplus power and / or shortage power, estimate the power consumption in the grid power supply, storage battery and power load for each demand group, calculate the demand, and calculate the surplus power between groups It can be coordinated with the demand.

  Also, communities accommodating multiple accommodation groups or demand groups may receive power from the same distribution substation.

  In addition, in the accommodation group, the accommodation planning unit 130 performs an operation to reduce the surplus amount as much as possible by performing the operation that maximizes the independence rate that maximizes natural energy at the time of charging plan preparation, and then the surplus. A plan can be developed to adapt the surplus power to accommodate the minutes between the accommodation group and the demand group.

  In addition, when the surplus is left in the prediction of the whole community that accommodates a plurality of accommodation groups or demand groups, the accommodation planning unit 130 reallocates the demand margin to remove inconsistency and recalculates until there is no surplus power. Can be repeated.

  Further, when the accommodation planning unit 130 allocates the surplus power to the demand generated in the demand group, there is no calculation of the surplus allocation in the prediction of the whole community accommodating the plurality of accommodation groups, or no power, and the priority is high. In the calculation when there is a demand, create a charge / discharge plan by discharging from the storage battery provided in the storage facility 94 with priority for the time zone of demand in one or more accommodation groups. Can.

  Also, one accommodation group or demand group can be composed of consumers having the same consumer attribute. The consumer attribute is, for example, information representing the feature or property of a building or facility such as a house, a commercial facility, a medical / welfare facility, an industrial facility, a public facility, or a disaster critical facility. Alternatively, one accommodation group or demand group can consist of customers having the same rate system. Also, one accommodation group or demand group can be composed of consumers having the same rate system and consumer attribute.

  Also, one accommodation group or demand group can be composed of a set of consumers connected to the same high voltage distribution feeder.

  Also, one area management server 100 may manage a plurality of communities accommodating a plurality of accommodation groups or demand groups.

  In addition, when allocating the surplus power to the demand generated in the demand group, the accommodation planning unit 130 gives priority to the supply demand demand of the demand group having the high electricity rate, when the electricity rate is different for each demand group. It is possible to discharge from the storage battery provided in the storage facility of the low charge accommodation group.

  Furthermore, when the accommodation planning unit 130 allocates surplus power to the demand generated in the demand group, if the electricity rate differs for each accommodation group or demand group, the demand request for the accommodation group or demand group having a low electricity rate Demand can be prioritized and assigned to the demand of the highest charge accommodation group or demand group.

  In addition, when allocation planning unit 130 allocates surplus power to the demand generated in the demand group, the electricity rate of the power discharged from the storage battery provided to power storage facility 94 for the supply demand demand is stored. It may be set higher than the electricity charge in the time zone of the group, and set higher than the electricity charge in the time zone of the demand group where the demand for supply has occurred.

  Further, when allocation planning unit 130 allocates surplus power to the demand generated in the demand group, the electricity rate of the power charged to the storage battery provided to power storage facility 94 for the demand demand demand is stored. It may be set higher than the electricity charge in the time zone of the group, and set higher than the electricity charge in the time zone of the demand group where the demand for supply has occurred.

  Furthermore, when allocating the surplus power to the demand generated in the demand group, when the charge contract of the demand group customer is a flat rate, the accommodation planning unit 130 uses the power exceeding the contracted power by the flat rate as the demand. And surplus power can be allocated to the demand.
