This power management device calculates the amount of change in the number of people in the supply area, which is estimated based on the number of people getting on and off at public transportation stops located within the supply area, and the amount of electricity supplied from the substation to the supply area. Based on this, the operation of power storage devices and power generation equipment installed within the supply area is controlled to adjust the supply and demand of electric power in the supply area.

For example, as shown in FIG. 1, the power management system according to the present embodiment supplies power to a plurality of customer facilities H by transmitting command information to the control device 32 installed in each of the plurality of customer facilities H. It includes a power management device 1 that manages power amount and a server 2 owned by a public transportation facility. The power management system also includes a substation equipment management device 4 that manages substation equipment PW installed in the substation. The power management device 1, the server 2, and the substation equipment management device 4 can communicate with each other via the network NW. The substation equipment PW is connected to a power distribution system PL for distributing power supplied from a power transmission system (not shown) to each of a plurality of consumer facilities H. The substation equipment management device 4 is installed, for example, in a substation together with the substation equipment PW, and continuously acquires power consumption information indicating the amount of power supplied to the consumer facility H, that is, the amount of power consumed, from the substation equipment PW. ing. When the substation equipment management device 4 receives the power consumption amount request information from the power management device 1 via the network NW, it generates power consumption amount information indicating the power consumption amount at the time of receiving the power consumption amount request information. Then, the substation equipment management device 4 transmits the generated power consumption information to the power management device 1 via the network NW.

Each of the plurality of consumer facilities H is provided with a connector 34 that is electrically connected to a stationary power storage device 33 or a power storage device (not shown) built in the vehicle V1. Further, each of the plurality of customer facilities H includes a power conditioner 31 for charging and discharging the power storage device 33 or the power storage device B1 built in the vehicle V1, and a control device 32 for controlling the power conditioner 31. is set up. Here, the vehicle V1 is a vehicle that includes a built-in power storage device B1, such as an electric vehicle or a hybrid vehicle. The power conditioner 31 has a bidirectional AC-DC converter, and converts AC power supplied from the power distribution system PL into DC power and outputs it to the power storage devices 33 and B1 to charge them. , B1 is converted into AC power and supplied to the power distribution system PL.

The control device 32 controls the power conditioner 31 based on discharge command information or charge command information received from the power management device 1 via the network. Here, the discharge command information is information that the power management device 1 instructs the control device 32 to discharge the power storage device 33, B1, and the charging command information is the information that the power management device 1 instructs the control device 32 to discharge the power storage device 33, B1. This is information that instructs charging of the device 33, B1. When the control device 32 receives the discharge command information from the power management device 1, the control device 32 operates the power conditioner 31 in the discharge mode to discharge the power storage device 33, B1 and transfer power from the power storage device 33, B1 to the power distribution system PL. supply. On the other hand, upon receiving the charging command information from the power management device 1, the control device 32 operates the power conditioner 31 in a charging mode to charge the power storage devices 33 and B1 with the power supplied from the power distribution system PL. The control device 32 also receives resource information request information from the power management device 1 via the network NW, requesting the control device 32 to transmit resource information including operating state information indicating the operating mode of the power conditioner 31. Suppose that it is received. In this case, the control device 32 controls the power conditioner based on information indicating the storage capacity, remaining amount of storage, discharge power, and charging power of the power storage device 33 and B1, and the discharge command information or charge command information transmitted from the power management device 1. Resource information including control status information indicating whether or not the controller 31 is being controlled is generated. Here, the control device 32 and the power storage devices 33 and B1 can communicate with each other via a communication interface that complies with, for example, the ECHONET Lite standard. Control device 32 then acquires information indicating the set values of charging power and discharging power of power storage device 33 and B1 from power storage device 33 via this communication interface. Further, the control device 32 transmits the generated resource information to the power management device 1 via the network NW.

The server 2 is installed, for example, in a management office of a public transportation facility, and manages information on the number of passengers getting on and off, including information on the number of people getting on board at a public transportation stop and information on the number of people getting off the train at the aforementioned stop. are doing. Here, the public transportation is, for example, a railway, and in this case, the stop is a railway station. Note that public transportation is not limited to railways, and may be, for example, buses. When the server 2 receives the number of boarding and alighting request information requesting the server 2 to transmit the number of boarding and alighting information from the power management device 1 via the network NW, the server 2 selects the number of boarding and alighting information from among the number of boarding and alighting information to be managed at the time of reception. The information on the number of passengers getting on and off the train, including the information on the number of people on board and the number of people getting off the train, at the station indicated by the station information included in the information on the number of passengers getting on and off the train is specified. Then, the server 2 transmits the identified information on the number of passengers getting on and off the vehicle to the power management device 1 via the network NW.

For example, as shown in FIG. 2, the power management device 1 includes a CPU (Central Processing Unit) 101, a main storage section 102, an auxiliary storage section 103, a communication interface 104, and a bus 109 that connects these to each other. Be prepared. The main storage unit 102 is a volatile memory such as RAM (Random Access Memory), and is used as a work area for the CPU 101. The auxiliary storage unit 103 is a nonvolatile memory such as a semiconductor flash memory or a magnetic disk, and stores programs for the CPU 101 to execute various processes. Communication interface 104 is connected to network NW.

By reading out the program stored in the auxiliary storage unit 103 to the main storage unit 102 and executing it, the CPU 101 acquires information on the number of passengers getting on and off 111, the amount of change in the number of people present, estimating unit 112, and the amount of power consumption, as shown in FIG. It functions as a prediction unit 113, a determination unit 114, a mode management unit 115, a specification unit 116, a command unit 117, an excess/deficiency calculation unit 119, and a power acquisition unit 120. Further, as shown in FIG. 3, the auxiliary storage unit 103 shown in FIG. It has an information storage section 135.

For example, as shown in FIG. 4, the number of passengers storage unit 131 stores information on the number of people getting on and off the train at a station, station identification information for identifying the station, and a supply area to which electricity is supplied to which the surrounding area of the station belongs. and substation identification information that identifies the substation corresponding to the substation. For example, as shown in Figure 5, the area around station A, the area around station B, and the area around station C belong to the power supply area of substation A, and the area around station D and the area around station E belong to the power supply area of substation B. Suppose that it belongs to . In this case, the number of boarding and alighting storage unit 131 stores information on the number of passengers at stations A, B, and C, "DABA," "DABB," and "DABC," and information on the number of passengers alighting, "DAGA," "DAGB," and "DAGC." is stored in association with substation identification information "IDA" that identifies substation A. In addition, the boarding/alighting passenger number storage unit 131 converts the boarding/alighting number information "DABD", "DABE" and the boarding/alighting number information "DAGD", "DAGE" at D station and E station into substation identification information for identifying the B substation. It is stored in association with "IDB".

For example, as shown in FIG. 6, the power consumption storage unit 132 stores power consumption information indicating the power consumption in each of the plurality of supply areas in a substation that identifies a substation that supplies power to each of the plurality of supply areas. The information is stored in association with the location identification information. For example, as shown in FIG. 7, the power supply mode storage unit 133 stores power supply mode information indicating the power supply mode in each of the plurality of supply areas, from a substation that identifies a substation that supplies power to each of the plurality of supply areas. It is stored in association with identification information. There are three types of power supply modes: "no control mode," "power suppression mode," and "power storage request mode." Here, in the "power suppression mode", electricity is sold to the consumer facility H, that is, electricity is supplied from the substation to the supply area by supplying electricity from the electricity storage device 33 or the automobile electricity storage device B1 to the distribution system. This mode suppresses power consumption. This "power suppression mode" is set when the amount of power consumed in the supply area is likely to exceed the power supply capacity of the substation equipment PW of the substation. Furthermore, the "power storage request mode" is a mode in which a request is made to the consumer facility H to purchase power, that is, to charge the power storage device 33 or the power storage device of the automobile with power to be supplied to the power distribution system. This "power storage request mode" is set when there is surplus power to be supplied from the substation equipment PW to the supply area and power consumption in the supply area is promoted. Furthermore, "uncontrolled mode" refers to control of charging and discharging of the power storage device 33 or the power storage device of the automobile by transmitting charging command information or discharge command information from the power management device 1 to the control device 32 of each customer facility H. This is a mode that does not perform This "uncontrolled mode" is set when the power supplied from the substation equipment PW to the supply area is neither tight nor excessive. In the example shown in FIG. 7, a supply area to which power is supplied from substation A and substation B sells electricity stored in the power storage device 33 or the power storage device of a car to customer facility H located there. The supply area to which electricity is supplied from L substation is set to "power suppression mode" and is set to "power storage request mode" which forces customer facility H located there to purchase electricity to be supplied to the distribution system. It is set.

Returning to FIG. 3, the reference storage unit 134 stores a first power consumption upper limit that is a reference value for the predicted power consumption for switching the power supply mode of the supply area from "uncontrolled mode" to "power suppression mode". information indicating the value, and information indicating a first power consumption lower limit value that is a reference value for the predicted power consumption for switching the power supply mode of the supply area from "uncontrolled mode" to "power storage request mode"; remember. The reference storage unit 134 also stores information indicating a second power consumption upper limit value that is a reference value for the predicted power consumption amount for switching the power supply mode of the supply area from "power suppression mode" to "uncontrolled mode". and information indicating a second lower limit value of power consumption, which is a reference value for predicted power consumption for switching the power supply mode of the supply area from "power storage request mode" to "uncontrolled mode".

For example, as shown in FIG. 8, the resource information storage unit 135 is configured to charge resources related to power supply installed in each of the plurality of customer facilities H, that is, the power storage device 33 or the power storage device B1 built in the vehicle V1. Installation location information indicating the installation location of the connector 34, resource type information indicating the type of resource, and operating state information indicating the operating state are stored in association with customer identification information identifying the customer facility H. The resource information storage unit 135 also stores power storage capacity information indicating the power storage capacity of the power storage device 33, B1, power storage remaining amount information showing the remaining power storage amount, charging power information showing the charging power during charging, and discharging power information during discharging. Stores discharge power information indicating power. Furthermore, the resource information storage unit 135 stores operation information indicating whether or not the user performs a setting operation on the power conditioner 31, and the control device 32 controls the power conditioner 31 based on discharge command information or charging command information from the power management device 1. Control status information indicating whether or not the controller is being controlled is stored. Here, FC0 (no control) in the control state information is a state in which the control device 32 independently controls the power conditioner 31 regardless of the discharge command information or charge command information from the power management device 1. . On the other hand, FC1 (control) in the control state information is a state in which the control device 32 is controlling the power conditioner 31 according to the discharge command information or charge command information from the power management device 1. In the example shown in FIG. 8, consumers C[0], C[1], C[3], and C[5] own stationary power storage devices 33, and consumers C[2], C[4] ] owns the connector 34 connected to the power storage device built into the vehicle V1, the vehicle V1 is connected to the connector owned by the consumer C[2], and the connector 34 owned by the consumer C[4] indicates that the car V1 is not connected. In addition, the power conditioners 31 owned by consumers C[0] and C[3] operate in charging mode, the power conditioner 31 owned by consumer C[1] operates in discharge mode, and [2], the power conditioner 31 owned by C[5] is stopped.

Returning to FIG. 3, the boarding/alighting passenger number information acquisition unit 111 acquires boarding/alighting passenger number information transmitted from the server 2 by transmitting the aforementioned boarding/alighting passenger number request information to the server 2 via the network NW. The boarding/alighting number information acquisition unit 111 stores the boarding/alighting number information included in the boarding/alighting number information, which is included in the boarding/alighting number information, in the boarding/alighting number storage unit 131 in association with the station identification information and the substation identification information.

Based on the number of people getting on and off at the station, the number-of-people-in-person change estimating unit 112 estimates the number of people-in-person change, which is the amount of change in the number of people in the supply area corresponding to the substation. Here, for example, as shown in Figure 5, people who get off at A, B, C, D, and E stations have various reasons such as living, staying overnight, working, attending school, shopping, leisure, etc. Therefore, they are located in the surrounding areas. On the other hand, people who board the train at A, B, C, D, and E stations will leave those areas. The number-of-occupancy change estimation unit 112 estimates the past number of stations for each station (for example, A station, B station, and C station) within the supply area (for example, the power supply area of A substation) that is the target of estimating the change in the number of people present. Based on the change in the number of passengers at each station within the supply area, the number of passengers at each station within the target supply area after a preset unit time from the current time is estimated. Here, the unit time is set, for example, based on the average time it takes for people who get off the train at each station in the target supply area to arrive at their residence. For example, as shown in FIG. 9C, the number of occupants change estimating unit 112 calculates the number of passengers Nb[i], Nb[i-1], Nb Based on [i-2], . . . , an approximate curve S1 indicating the change in the number of passengers over time is calculated by polynomial approximation using the least squares method. Next, the number of occupants change estimating unit 112 estimates the number of passengers Nb[i+1] at time t[i+1], which is a unit time later than current time t[i], based on the approximate curve S1. Then, the number-of-occupancy change estimation unit 112 calculates the number of people obtained by subtracting the estimated number of passengers from the number of people getting off at each station in the target supply area at the present time, and calculates the number of people present as the amount of change in the number of people present after the above-mentioned unit time from the present time. do. For example, as shown in FIG. 9(B), the number of people at the location estimating unit 112 calculates the number of people at the current time by subtracting the estimated number of passengers Nb[i+1] from the number of people getting off the train Ng[i] at the current time t[i]. Let it be the amount of change in the number of people present after the unit time mentioned above.

Returning to FIG. 3, the power acquisition unit 120 transmits the power consumption request information to the substation equipment management device 4 via the network NW, so that the substation equipment management device 4 installed is transmitted from the substation equipment management device 4. The power consumption information indicating the current power consumption of the power supply area from the specified substation is acquired. The power acquisition unit 120 stores the acquired power consumption information in the power consumption storage unit 132 in association with the substation identification information.

The power consumption prediction unit 113 calculates the consumption as shown in FIG. Calculated as the amount of power change. Then, the power consumption prediction unit 113 calculates the predicted power consumption by adding the calculated power consumption change amount to the current power consumption indicated by the power consumption information acquired by the power acquisition unit 120.

The determination unit 114 determines that when the power supply mode of the supply area is set to the above-mentioned uncontrolled mode, the predicted power consumption calculated by the power consumption prediction unit 113 is the first power consumption stored in the reference storage unit 134. It is determined whether the amount of power consumption is less than the upper limit value and greater than or equal to the first lower limit value of the amount of power consumption stored in the reference storage unit 134. Further, when the power supply mode of the supply area is set to the power suppression mode described above, the determination unit 114 determines that the predicted power consumption calculated by the power consumption prediction unit 113 is the second one stored in the reference storage unit 134. It is determined whether the power consumption amount is less than the upper limit value. Further, when the power supply mode of the supply area is set to the power storage request mode described above, the determination unit 114 determines that the predicted power consumption calculated by the power consumption prediction unit 113 is the second one stored in the reference storage unit 134. It is determined whether the amount of power consumption is larger than the lower limit value.

When the power supply mode of the supply area is set to uncontrolled mode, the mode management unit 115 determines that the predicted power consumption calculated by the power consumption prediction unit 113 by the determination unit 114 is lower than the first power consumption upper limit value. If it is determined that the power supply area is large, the power supply mode of the target supply area stored in the power supply mode storage unit 133 is updated to the power suppression mode. In addition, when the power supply mode of the supply area is set to the uncontrolled mode, the mode management unit 115 determines that the predicted power consumption calculated by the power consumption prediction unit 113 by the determination unit 114 is the first power consumption lower limit. If it is determined that the power supply area is less than the current value, the power supply mode of the target supply area stored in the power supply mode storage unit 133 is updated to the power storage request mode. Furthermore, when the power supply mode of the supply area is set to the power suppression mode, the mode management unit 115 determines that the predicted power consumption calculated by the power consumption prediction unit 113 by the determination unit 114 is the second power consumption upper limit value. If it is determined that the power supply mode is less than the power supply area, the power supply mode of the target supply area stored in the power supply mode storage unit 133 is updated to the uncontrolled mode. In addition, when the power supply mode of the supply area is set to the power storage request mode, the mode management unit 115 determines that the predicted power consumption calculated by the power consumption prediction unit 113 by the determination unit 114 is the second power consumption lower limit. If it is determined that the power supply mode is larger than , the power supply mode of the target supply area stored in the power supply mode storage unit 133 is updated to the uncontrolled mode. Here, as shown in FIG. 10(A), the first power consumption upper limit value is larger than the second power consumption upper limit value, and the first power consumption lower limit value is larger than the second power consumption lower limit value. It's also small. As shown in FIG. 10B, the mode management unit 115 calculates the predicted power consumption, a first power consumption upper limit value, a first power consumption lower limit value, a second power consumption upper limit value, or a second power consumption amount. The power supply mode is changed depending on the magnitude relationship between the lower limit value and the lower limit value. Here, the power supply mode always goes through the uncontrolled mode when transitioning from the power suppression mode to the power storage request mode or from the power storage request mode to the power restriction mode.

Returning to FIG. 3, when the power supply mode is set to the power suppression mode, the surplus/deficiency calculation unit 119 calculates the power shortage obtained by subtracting the first power consumption upper limit value from the predicted power consumption. . Furthermore, when the power supply mode is set to the power suppression mode and the discharge command information is transmitted to the control device 32, the surplus/deficiency calculation unit 119 refers to the discharge power information stored in the resource information storage unit 135 and calculates the predicted consumption. The power shortage is calculated by subtracting the discharge power of the power storage device 33, B1 corresponding to the control device 32 to which the discharge command information is transmitted from the power deficit obtained by subtracting the first power consumption upper limit value from the power amount. do. On the other hand, when the power supply mode is set to the power storage request mode, the surplus/deficiency calculating unit 119 calculates the excess power amount obtained by subtracting the predicted power consumption amount from the first power consumption lower limit value. Further, when the power supply mode is set to the power storage request mode and the charging command information is transmitted to the control device 32, the surplus/deficiency calculation unit 119 refers to the charging power information stored in the resource information storage unit 135, and calculates the first The excess power amount is calculated again by subtracting the charging power of the power storage device 33, B1 corresponding to the control device 32 to which the charging command information is transmitted from the excess power amount obtained by subtracting the predicted power consumption amount from the power consumption lower limit value. calculate.

The resource information acquisition unit 121 associates the operating state information, storage capacity information, remaining storage amount information, charging power information, discharge power information, operation information, and control state information included in the acquired resource information with customer identification information. and stored in the resource information storage unit 135.

The specifying unit 116 specifies, from among the control devices 32 installed in each of the customer facilities H, the control device 32 to which the discharging command information or the charging command information is transmitted. When the power supply mode is set to the power suppression mode, the identification unit 116 identifies the control device 32 to which the discharge command information is transmitted based on the power shortage calculated by the excess/deficiency calculation unit 119. Further, when the power supply mode is set to the power storage request mode, the identifying unit 116 identifies the control device 32 to which the charging command information is transmitted based on the excess power amount calculated by the surplus/deficit calculating unit 119.

First, it is assumed that a preset command time has arrived for transmitting charging command information or discharging command information from the power management device 1 to the control device 32 installed in the customer facility H located within the supply area. This command timing may be set, for example, to arrive at preset time intervals, for example, every 5 minutes. In this case, the power management device 1 transmits to the server 2 the number of passengers information requesting information that requests the server 2 to transmit the above-mentioned information on the number of passengers getting on and off for each station located within the supply area (step S1). On the other hand, the server 2 specifies the number of passengers boarding and alighting information including the number of boarding and alighting information at the station indicated by the station information included in the number of boarding and alighting information included in the number of boarding and alighting information at the time of reception, from among the number of boarding and alighting information that it manages. Step S2). Next, the information on the number of people getting on and off the vehicle, which is specified by the server 2, is transmitted from the server 2 to the power management device 1 (step S3). On the other hand, the power management device 1 estimates the amount of change in the number of people present in the supply area after a preset unit time from the current time based on the information on the number of passengers and the information on the number of people alighting included in the information on the number of passengers getting on and off (step S4 ).

Next, a power consumption amount request is sent to the substation equipment management device 4 installed in the substation in the target supply area to request transmission of power consumption information indicating the amount of power currently supplied from the substation to the supply area. Information is transmitted from the power management device 1 to the substation equipment management device 4 (step S5). On the other hand, upon receiving the power consumption amount request information, the substation equipment management device 4 generates power consumption amount information indicating the amount of power currently supplied from the substation to the supply area (step S6). Thereafter, the generated power consumption information is transmitted from the substation equipment management device 4 to the power management device 1 (step S7). On the other hand, upon receiving the power consumption information, the power management device 1 calculates the predicted power consumption in the supply area after a unit time from the current time based on the current power consumption and the amount of change in the number of people present, which are indicated by the received power consumption information. A power amount P[i+1] is calculated (step S8).

Next, the power management device 1 refers to the information indicating the first power consumption upper limit value Pth1 and the first power consumption lower limit value Ptl1 stored in the reference storage unit 134, and calculates the predicted power consumption amount P[i+1]. Suppose that it is determined that the power consumption amount is less than or equal to the first power consumption upper limit value Pth1 or more than the first power consumption amount lower limit value Ptl1 (step S9). In this case, the power management device 1 identifies the customer facility H located in the supply area to which the discharge command information or the charge command information is to be transmitted (step S10). Then, resource information request information requesting the control device 32 to transmit resource information regarding the power storage devices 33 and B1 installed in the specified customer facility H is transmitted from the power management device 1 to the specified customer facility H. The information is transmitted to the installed control device 32 (step S11). On the other hand, upon receiving the resource information request information, the control device 32 generates resource information including the above-mentioned control state information (step S12). Subsequently, the generated resource information is transmitted from the control device 32 to the power management device 1 (step S13).

The control device 32 to be controlled is specified (step S14). Thereafter, stop command information that instructs the power conditioner 31 to stop operating is transmitted from the power management device 1 to the specified control device 32 (step S15). Then, upon receiving the stop command information, the control device 32 stops the operation of the power conditioner 31.

Further, as shown in FIG. 12, after the process of step S8 described above, the power management device 1 refers to the information indicating the first power consumption upper limit value Pth1 stored in the reference storage unit 134 and calculates the predicted power consumption. Assume that it is determined that P[i+1] is larger than the first power consumption upper limit value Pth1 (step S21). In this case, the power management device 1 switches the power supply mode for the target supply area from the uncontrolled mode to the power suppression mode (step S22), and selects the target supply area based on the installation location information stored in the resource information storage unit 135. The customer facility H located in the supply area is identified (step S23). Then, resource information request information requesting the control device 32 to transmit resource information regarding the power storage devices 33 and B1 installed in the specified customer facility H is transmitted from the power management device 1 to the specified customer facility H. The information is transmitted to the installed control device 32 (step S24). On the other hand, upon receiving the resource information request information, the control device 32 generates resource information including the above-mentioned control state information (step S25). Subsequently, the generated resource information is transmitted from the control device 32 to the power management device 1 (step S26).

On the other hand, the power management device 1 identifies the control device 32 that is not the destination of the discharge command information and the charge command information transmitted from the power management device 1, based on the control state information included in the received resource information (step S27). ). Thereafter, the power management device 1 determines that there is a remaining amount of power stored in the power storage device 33, B1 corresponding to the specified control device 32, based on the remaining amount of stored power information and the operating state information included in the received resource information, and determines that Assume that it is determined that the power conditioner 31 controlled by the device 32 is stopped and there is no setting operation on the control device 32 by the resident of the consumer facility H (step S28). In this case, discharge command information that commands the power conditioner 31 to operate in the discharge mode is transmitted from the power management device 1 to the specified control device 32 (step S29). Then, upon receiving the discharge command information, the control device 32 operates the power conditioner 31 in the discharge mode.

Then, when the power supply mode is set to the power suppression mode, the power management device 1 stores the information indicating the second power consumption upper limit value Pth2 stored in the reference storage unit 134 after the processing in step S8 described above. Assume that it is determined with reference that the predicted power consumption P[i+1] is less than the second power consumption upper limit Pth2 (step S30). In this case, the power management device 1 switches the power supply mode for the target supply area from the power suppression mode to the uncontrolled mode (step S31).

Further, as shown in FIG. 13, after the process of step S8 described above, the power management device 1 refers to the information indicating the first power consumption lower limit value Ptl1 stored in the reference storage unit 134 and calculates the predicted power consumption. Assume that it is determined that P[i+1] is less than the first power consumption lower limit value Ptl1 (step S41). In this case, the power management device 1 switches the power supply mode for the target supply area from the uncontrolled mode to the power storage request mode (step S42), and selects the target supply area based on the installation location information stored in the resource information storage unit 135. The customer facility H located in the supply area is specified (step S43). Then, resource information request information requesting the control device 32 to transmit resource information regarding the power storage devices 33 and B1 installed in the specified customer facility H is transmitted from the power management device 1 to the specified customer facility H. The information is transmitted to the installed control device 32 (step S44). On the other hand, upon receiving the resource information request information, the control device 32 generates resource information including the aforementioned control state information (step S45). Subsequently, the generated resource information is transmitted from the control device 32 to the power management device 1 (step S46).

On the other hand, the power management device 1 identifies the control device 32 that is not the destination of the discharge command information and the charge command information transmitted from the power management device 1, based on the control state information included in the received resource information (step S47). ). Thereafter, the power management device 1 determines that the power storage devices 33 and B1 corresponding to the specified control device 32 are capable of storing power, based on the power storage remaining amount information and the operating state information included in the received resource information, and that the power storage devices 33 and B1 corresponding to the specified control device Assume that it is determined that the power conditioner 31 controlled by the power conditioner 32 is stopped and there is no setting operation on the control device 32 by the resident of the consumer facility H (step S48). In this case, charging command information that commands the power conditioner 31 to operate in the charging mode is transmitted from the power management device 1 to the specified control device 32 (step S49). Then, upon receiving the charging command information, the control device 32 operates the power conditioner 31 in the charging mode.

Then, when the power supply mode is set to the power storage request mode, the power management device 1 stores the information indicating the second power consumption lower limit value Ptl2 stored in the reference storage unit 134 after the process of step S8 described above. Assume that it is determined that the predicted power consumption amount P[i+1] is larger than the second power consumption lower limit value Ptl2 with reference to it (step S50). In this case, the power management device 1 switches the power supply mode for the target supply area from the power storage request mode to the uncontrolled mode (step S51).

Next, power management processing executed by the power management device 1 according to the present embodiment will be described with reference to FIGS. 14 to 17. This power management process is started, for example, when the power management device 1 is powered on. Further, it is assumed that the power supply mode information stored in the power supply mode storage unit 133 is set to the uncontrolled mode immediately after power is turned on. First, as shown in FIG. 14, the passenger number information acquisition unit 111 determines whether the above-mentioned command timing has arrived (step S101). As long as the passenger number information acquisition unit 111 determines that the instruction time has not yet arrived (step S101: No), the process of step S101 is repeatedly executed. On the other hand, when the boarding/alighting passenger number information acquisition unit 111 determines that the instruction time has arrived, it transmits the boarding/alighting number request information to the server 2 (step S102), thereby obtaining the boarding/alighting number information transmitted from the server 2. (Step S103). Here, the number of passengers getting on and off information acquisition unit 111 stores information on the number of people on board and number of people getting off included in the information on the number of people getting on and off in the number of passengers storage unit 131 in association with the station identification information and the substation identification information. let

Next, based on the information on the number of people getting on board and the information on the number of people getting off the train stored in the number of people getting on and off the train, the estimation unit 112 calculates a change in the number of people in the area surrounding the station identified by the corresponding station identification information. The amount is estimated (step S104). Subsequently, the number-of-occupancy change amount estimating unit 112 determines whether estimation of the amount of change in the number of people present in the surrounding area of each station has been completed for all target stations (step S105). If the resident population change estimation unit 112 determines that there is a station among the target stations for which the change in the resident population in the area surrounding the station has not yet been estimated (step S105: No), the process of step S102 is performed again. executed. On the other hand, if the resident population change amount estimating unit 112 determines that the estimation of the resident population change amount in the surrounding area of each station has been completed for all target stations (step S105: Yes), the resident population change amount estimating unit 112 The amount of change in the number of people in the target supply area is calculated by adding up the amount of change in the number of people in the area surrounding the station (step S106). Thereafter, the number-of-people change estimating unit 112 determines whether calculation of the number of changes in the number of people present has been calculated for all target supply areas (step S107). If the resident population change amount estimating unit 112 determines that there is a supply area in the target supply area for which calculation of the resident population change amount has not yet been completed (step S107: No), it executes the process of step S106 again. do.

On the other hand, it is assumed that the resident population change estimation unit 112 determines that the resident population change amount has been calculated for all target supply areas (step S107: No). In this case, the power acquisition unit 120 transmits the above-mentioned power consumption request information to the substation equipment management device 4 (step S108), and acquires the power consumption information transmitted from the substation equipment management device 4 (step S108).

Next, as shown in FIG. 15, the determination unit 114 refers to the power supply mode information stored in the power supply mode storage unit 133 and determines whether the power supply mode is the aforementioned uncontrolled mode. (Step S111). If the determination unit 114 determines that the power supply mode is not the uncontrolled mode (step S111: No), the process of step S116, which will be described later, is executed. On the other hand, when determining that the power supply mode is the uncontrolled mode (step S111: Yes), the determining unit 114 determines whether the predicted power consumption P[i+1] is larger than the first power consumption upper limit value Pth1. Determination is made (step S112). When the determination unit 114 determines that the predicted power consumption P[i+1] is larger than the first power consumption upper limit value Pth1 (step S112: Yes), the mode management unit 115 determines that the power supply mode storage unit 133 The power supply mode information is updated to the power suppression mode (step S113), and then the process of step S121, which will be described later, is executed. On the other hand, when determining that the predicted power consumption P[i+1] is equal to or less than the first power consumption upper limit Pth1 (step S112: No), the determination unit 114 determines that the predicted power consumption P[i+1] is the first power consumption lower limit. It is determined whether it is less than the value Ptl1 (step S114). When the determination unit 114 determines that the predicted power consumption P[i+1] is less than the first power consumption lower limit value Ptl1 (step S114: Yes), the mode management unit 115 selects the power stored in the power supply mode storage unit 133. The supply mode information is updated to the power storage request mode (step S115), and then the process of step S121, which will be described later, is executed. On the other hand, if the determination unit 114 determines that the predicted power consumption P[i+1] is equal to or greater than the first power consumption lower limit value Ptl1 (step S114: Yes), the process of step S121, which will be described later, is directly executed.

Further, when determining in step S111 that the power supply mode is not the uncontrolled mode (step S111: No), the determining unit 114 determines whether the power supply mode is the power suppression mode (step S116). When the determination unit 114 determines that the power supply mode is not the power suppression mode (step S116: No), the process of step S119, which will be described later, is executed. On the other hand, when determining that the power supply mode is the power suppression mode (step S116: Yes), the determination unit 114 determines whether the predicted power consumption P[i+1] is less than the second power consumption upper limit Pth2. Determination is made (step S117). When the determination unit 114 determines that the predicted power consumption P[i+1] is less than the second power consumption upper limit value Pth2 (step S117: Yes), the mode management unit 115 determines that the power supply mode storage unit 133 The power supply mode information is updated to uncontrolled mode (step S118), and then the process of step S121, which will be described later, is executed. On the other hand, if the determination unit 114 determines that the predicted power consumption P[i+1] is equal to or greater than the second power consumption upper limit value Pth2 (step S117: No), the process of step S121, which will be described later, is directly executed.

Further, when determining in step S116 that the power supply mode is not the power suppression mode (step S116: No), the determination unit 114 determines that the power supply mode is the power storage request mode. Then, the determining unit 114 determines whether the predicted power consumption P[i+1] is larger than the second power consumption lower limit value Ptl2 (step S119). When the determination unit 114 determines that the predicted power consumption P[i+1] is larger than the second power consumption lower limit value Ptl2 (step S119: Yes), the mode management unit 115 determines that the power supply mode storage unit 133 The power supply mode information is updated to uncontrolled mode (step S120), and then the process of step S121, which will be described later, is executed. On the other hand, if the determination unit 114 determines that the predicted power consumption P[i+1] is equal to or less than the second power consumption upper limit value Pth2 (step S119: No), the mode management unit 115 sets the power supply mode for all the supply areas. is set (step S121). If the mode management unit 115 determines that there is a supply area in which the power supply mode has not yet been set (step S121: No), the process of step S111 is executed again.

On the other hand, if the mode management unit 115 determines that the power supply mode has been set for all the supply areas (step S121: Yes), the identification unit 116 determines the target power supply mode based on the installation location information stored in the resource information storage unit 135. The customer facility H located in the supply area is specified (step S122). Thereafter, the resource information acquisition unit 121 transmits the resource information request information to the control device 32 installed in one of the specified customer facilities H (step S123). Resource information including operating state information, power storage capacity information, power storage remaining amount information, charging power information, discharge power information, operation information, and control state information is acquired (step S124). At this time, the resource information acquisition unit 121 converts the operating state information, power storage capacity information, power storage remaining amount information, charging power information, discharge power information, operation information, and control state information included in the acquired resource information into consumer identification information. The information is stored in the resource information storage unit 135 in association with the resource information storage unit 135. Next, the resource information acquisition unit 121 determines whether resource information has been acquired from the control devices 32 installed in all the customer facilities H within the specified supply area (step S125). It is assumed that the resource information acquisition unit 121 determines that there is a control device 32 that has not yet acquired resource information among the control devices 32 installed at the customer facility H in the specified supply area (step S125: No). In this case, the process of step S123 is executed again.

On the other hand, it is assumed that the resource information acquisition unit 121 determines that resource information has been acquired from the control devices 32 installed in each of all the customer facilities H within the specified supply area (step S125: Yes). In this case, the mode management unit 115 refers to the power supply mode information stored in the power supply mode storage unit 133 and determines whether the power supply mode is set to the uncontrolled mode (step S126). If the mode management unit 115 determines that the power supply mode is not set to the uncontrolled mode (step S126: No), the process of step S130, which will be described later, is executed. On the other hand, if the mode management unit 115 determines that the power supply mode is set to the uncontrolled mode (step S126: Yes), the identification unit 116 determines that the power supply mode is set to the uncontrolled mode, 32, it is determined whether there is a control device 32 to which the discharge command information or charge command information is transmitted (step S127). When the identification unit 116 determines that there is no control device 32 to which the discharge command information or charging command information is transmitted among the control devices 32 installed in the customer facility H located in the supply area (step S127: No). ), the process of step S145 shown in FIG. 17, which will be described later, is executed. On the other hand, if the specifying unit 116 determines that there is a control device 32 to which the discharge command information or charge command information is transmitted among the control devices 32 installed in the customer facility H located in the supply area (step S127: Yes), the control device 32 to which the discharge command information or charge command information is transmitted is specified. Then, the command unit 117 generates the above-mentioned stop command information and transmits it to the specified control device 32 (step S128). Here, upon receiving the stop command information, the control device 32 stops the power conditioner 31. After that, the command unit 117 updates the contents of the control state information stored in the resource information storage unit 135 without any control (step S129), and the process of step S127 is executed again.

Furthermore, when determining in step S126 that the power supply mode is not set to the uncontrolled mode (step S126: No), the mode management unit 115 determines whether the power supply mode is set to the power suppression mode. (Step S130). If the mode management unit 115 determines that the power supply mode is not set to the power suppression mode (step S130: No), the process of step S138 shown in FIG. 17, which will be described later, is executed. On the other hand, if the mode management unit 115 determines that the power supply mode is set to the power suppression mode (step S130: Yes), the surplus/deficiency calculation unit 119 calculates the first power consumption upper limit value from the predicted power consumption. A power shortage obtained by subtraction is calculated (step S131). Next, the identification unit 116 determines whether or not there is a control device 32 that is not a destination of the discharge command information or the charging command information among the control devices 32 installed in the customer facility H located in the supply area. (Step S132). When the identifying unit 116 determines that there is no control device 32 installed in the customer facility H located in the supply area that is not the destination of the discharge command information or the charging command information (step S132: No). , the process of step S145 shown in FIG. 17, which will be described later, is executed.

On the other hand, if the identifying unit 116 determines that there is a control device 32 installed in the customer facility H located in the supply area that is not the destination of the discharge command information or the charge command information (step S132: Yes), the control device 32 that is not the destination of the discharge command information or the charge command information is identified. The identifying unit 116 determines that there is a remaining amount of power in the power storage device 33, B1, corresponding to the identified control device 32, that the power conditioner 31 controlled by the identified control device 32 is stopped, and that the power conditioner 31 of the customer facility H It is determined whether or not the resident has performed a setting operation on the control device 32 (step S133). The identifying unit 116 determines that the power storage device 33, B1 corresponding to the identified control device 32 has no remaining power storage capacity, the power conditioner 31 controlled by the identified control device 32 is in operation, or the customer facility H is occupied. If it is determined that the user has performed a setting operation on the control device 32 (step S133: No), the process of step S132 is executed again. Here, when determining that there is a setting operation on the control device 32 by a resident of the customer facility H, the identifying unit 116 updates the content of the control state information stored in the resource information storage unit 135 to uncontrolled.

On the other hand, it is assumed that the specifying unit 116 determines that there is a remaining power storage amount in the power storage device 33, B1, corresponding to the specified control device 32, and that the power conditioner 31 controlled by the specified control device 32 is stopped ( Step S133: Yes). In this case, the command unit 117 generates the above-mentioned discharge command information and transmits it to the specified control device 32 (step S134). After that, the command unit 117 updates the content of the control state information stored in the resource information storage unit 135 to control (step S135). Next, the surplus/deficiency calculation unit 119 refers to the discharge power information stored in the resource information storage unit 135 and calculates a discharge command from the power shortage obtained by subtracting the first power consumption upper limit value from the predicted power consumption. The power shortage is calculated again by subtracting the discharged power of the power storage device 33, B1, corresponding to the control device 32 that is the destination of the information (step S136). Subsequently, the identifying unit 116 determines whether there is a power shortage based on the calculated power shortage (step S137). Here, the identifying unit 116 determines that there is no power shortage if the calculated power shortage is 0 or less. If the identifying unit 116 determines that there is a power shortage (step S137: No), it executes the process of step S132 again. On the other hand, if the identifying unit 116 determines that there is no power shortage (step S137: Yes), the process of step S145 shown in FIG. 17, which will be described later, is executed.

Furthermore, if the mode management unit 115 determines in step S130 that the power supply mode is not set to the power suppression mode (step S130: No), it determines that the power supply mode is set to the power storage request mode. Then, as shown in FIG. 17, the surplus/deficiency calculation unit 119 calculates the excess power amount obtained by subtracting the predicted power consumption from the first power consumption lower limit value (step S138). Next, the identification unit 116 determines whether or not there is a control device 32 installed in the customer facility H located in the supply area that is not the destination of the discharge command information or the charging command information. (Step S139). When the identification unit 116 determines that there is no control device 32 installed in the customer facility H located in the supply area that is not the destination of the discharge command information or the charging command information (step S139: No). ), the process of step S145, which will be described later, is executed.

On the other hand, if the specifying unit 116 determines that there is a control device 32 that is not the destination of the discharge command information or the charge command information among the control devices 32 installed in the customer facility H located in the supply area (step S139: Yes), the control device 32 that is not the destination of the discharge command information or the charge command information is specified. The identifying unit 116 then determines that the power storage device 33, B1 corresponding to the identified control device 32 is capable of storing power, the power conditioner 31 controlled by the identified control device 32 is stopped, and the customer facility H is occupied. It is determined whether there is any setting operation on the control device 32 by the person (step S140). The identification unit 116 determines that the power storage device 33, B1 corresponding to the identified control device 32 is not capable of storing electricity, the power conditioner 31 controlled by the identified control device 32 is in operation, or the user is a resident of the customer facility H. If it is determined that there is a setting operation for the control device 32 (step S140: No), the process of step S139 is executed again. Here, when determining that there is a setting operation on the control device 32 by a resident of the customer facility H, the identifying unit 116 updates the content of the control state information stored in the resource information storage unit 135 to uncontrolled.

On the other hand, assume that the specifying unit 116 determines that the power storage device 33, B1 corresponding to the specified control device 32 is capable of storing electricity, and that the power conditioner 31 controlled by the specified control device 32 is stopped (step S140: Yes). In this case, the command unit 117 generates the above-mentioned charging command information and transmits it to the specified control device 32 (step S141).

After that, the command unit 117 updates the content of the control state information stored in the resource information storage unit 135 to control (step S142). Next, the surplus/deficiency calculation unit 119 refers to the charging power information stored in the resource information storage unit 135 and calculates a charging command from the excess power amount obtained by subtracting the predicted power consumption from the first power consumption lower limit value. The excess power amount is calculated again by subtracting the charging power of the power storage device 33, B1, corresponding to the control device 32 as the information transmission destination (step S143). Subsequently, the identifying unit 116 determines whether or not there is excess power based on the calculated excess power amount (step S144). Here, the identification unit 116 determines that there is no excess power if the calculated excess power amount is 0 or less. If the identifying unit 116 determines that there is excess power (step S144: No), it executes the process of step S139 again. On the other hand, when determining that there is no excess power (step S144: Yes), the identifying unit 116 determines whether the resource information corresponding to the customer facility H located in the supply area has been updated for all target supply areas. is determined (step S145). If the identifying unit 116 determines that there is a supply area in the target supply area that has not yet updated the resource information corresponding to the customer facility H located in the supply area (step S145: No), the identification unit 116 updates the diagram again. 16 is executed in step S122. On the other hand, if the identifying unit 116 determines that the resource information corresponding to the customer facility H located in the supply area has been updated for all target supply areas (step S145: Yes), step S101 shown in FIG. Processing is executed.

As explained above, according to the power management device 1 according to the present embodiment, the number of people present in the supply area estimation unit 112 estimates the amount of change in the number of people present in the supply area based on the number of people getting on and the number of people getting off at the station. do. Further, the power consumption prediction unit 113 calculates the predicted power consumption at a point in time after a preset unit period from the present time, based on the amount of change in the number of people in the supply area and the current power consumption in the supply area at the present time. calculate. Then, the command unit 117 generates either discharge command information or charging command information based on the predicted power consumption amount, and controls the charging and discharging of the power storage devices 33 and B1 existing in the supply area. The information is sent to the device 32. In other words, by using the information on the number of passengers getting on and off at stations managed by the server 2 owned by public transportation, and considering the movement of residents of customer facilities H located in each supply area, supply to the supply area is achieved. Since the expected power consumption amount can be predicted with high accuracy, power can be appropriately supplied to the plurality of consumer facilities H existing within the supply area.

By the way, with the spread of transportation IC cards in public transportation such as buses and trains, systems have been widely introduced to charge public transportation users based on information on the number of people getting on and off at stations and bus stops. has been done. Along with this, information on the number of people getting on board and getting off the bus at public transportation stations and bus stops is being recorded in real time on the server 2 managed by the public transportation agency. The increase or decrease in the number of residents of customer facility H located in the area surrounding a station or bus stop during a certain time period is determined by the number of people getting on and off at the station or bus stop during that time period, which is recorded on the server 2. It can be estimated from Here, an increase in the number of passengers at a station or bus stop is considered to be equivalent to an increase in the number of people going out of customer facility H, which is located in the area surrounding the station or bus stop. It can be predicted that the electricity demand will decrease. On the other hand, an increase in the number of people getting off the train at stations and bus stops means that they are likely to stay at customer facilities H such as workplaces, schools, and commercial facilities that exist in the area surrounding the station and bus stop, which increases the demand for electricity in the surrounding area. is expected to increase. The power management device 1 according to the present embodiment focuses on the correlation between the number of passengers getting on and off at a station or bus stop and the power demand in the surrounding area, and estimates the amount of change in power consumption in the surrounding area. , to predict the amount of electricity consumed in the surrounding area. Therefore, there is an advantage that the amount of change in power consumption in the area surrounding the station or bus stop can be predicted with high accuracy.

In addition, the power management device 1 according to the present embodiment repeats the series of processes from steps S101 to S145 described above every time a command timing arrives periodically at a preset time interval. The power supplied from the substation equipment PW of the substation is always leveled. Therefore, it is possible to stabilize the power supply from the substation to the supply area and to optimize the power supply resources including the substation equipment PW and power storage devices 33 and B1.

Furthermore, the mode management unit 115 according to the present embodiment switches the power supply mode based on the predicted power consumption predicted by the power consumption prediction unit 113. Then, the command unit 117 transmits discharge command information to the control device 32 when the power supply mode is set to power suppression mode, and transmits charging command information when the power supply mode is set to power storage request mode. It is transmitted to the control device 32. Thereby, the control device 32 can appropriately control the power conditioner 31 based on the predicted power consumption in the supply area, so that power adjustment in the supply area can be effectively performed.

Furthermore, when the predicted power consumption amount exceeds the first power consumption upper limit value, the mode management unit 115 according to the present embodiment sets the power supply mode to the power suppression mode, and sets the power supply mode to the power suppression mode. After that, when the predicted power consumption falls below the second power consumption upper limit value, the power suppression mode is canceled. Furthermore, when the predicted power consumption falls below the first power consumption lower limit value, the mode management unit 115 sets the power supply mode to the power storage request mode, and after setting the power supply mode to the power storage request mode, the predicted power consumption When the amount exceeds the second lower limit value of power consumption, the power storage request mode is canceled. As a result, it is possible to suppress frequent switching of power supply modes due to sudden fluctuations in predicted power consumption, so that discharging command information or charging command information is appropriately sent to the control device 32. Can be sent.

Furthermore, when the power supply mode is set to the power suppression mode, the surplus/deficiency calculation unit 119 according to the present embodiment calculates the power shortage based on the predicted power consumption and the first power consumption upper limit value. However, when the power supply mode is set to the power storage request mode, the excess power amount is calculated based on the first power consumption lower limit value and the predicted power consumption amount. Then, when the power supply mode is set to the power suppression mode, the identifying unit 116 identifies the control device 32 to which the discharge command information is transmitted based on the amount of power shortage, and changes the power supply mode to the power storage request mode. If set, the control device 32 to which the charging command information is transmitted is specified based on the excess power amount. As a result, the number of control devices 32 to which the discharge command information or charge command information is transmitted is increased one by one, and when the insufficient power amount or excess power amount disappears, the control device 32 of the charge command information or discharge command information You can stop sending to. Therefore, it is possible to suppress an excessive increase in the number of control devices 32 that control the power conditioner 31 based on the discharge command information or the charge command information.

On the other hand, if the identification unit 116 determines that the power shortage has not been resolved (step S5151: No), the mode management unit 115 refers to the power supply mode information stored in the power supply mode storage unit 133 and It is determined whether there is a substation whose power supply mode is set to uncontrolled mode among the substations interconnected with substation A that supplies power to A1 (step S5152). The mode management unit 115 has determined that there is a substation (for example, substation B) whose power supply mode is set to uncontrolled mode among the substations interconnected with substation A that supplies power to supply area A1. (Step S5152: Yes). In this case, mode management unit 115 switches the power supply mode for substation B to power suppression mode (step S5153). Next, a series of processes from steps S132 to S136 are executed for power storage devices 33 and B1 existing in supply area A2 to which power is supplied from substation B.

On the other hand, assume that the mode management unit 115 determines that there is no substation whose power supply mode is set to uncontrolled mode among the substations interconnected with substation A that supplies power to supply area A1 (step S5152: Yes). In this case, the mode management unit 115 refers to the power supply mode information stored in the power supply mode storage unit 133, and determines whether there is a power supply mode in the substation connected to the substation A that supplies power to the supply area A1. determines whether there is a substation set to power storage request mode (step S5154). Here, it is assumed that the mode management unit 115 determines that there is a substation whose power supply mode is set to the power storage request mode among the substations interconnected with the substation A that supplies power to the supply area A1 ( Step S5154: Yes). In this case, the mode management unit 115 switches the power supply mode for the substation to the uncontrolled mode, as shown in FIG. 29 (step S5155). Subsequently, the identification unit 116 determines whether or not there is a control device 32 to which the discharge command information or the charge command information is transmitted, among the control devices 32 installed in the customer facility H located in the supply area. (Step S5156). Here, if the specifying unit 116 determines that there is a control device 32 to which the discharge command information or charge command information is transmitted among the control devices 32 installed in the customer facility H located in the supply area (step S5156 :Yes), the control device 32 to which the discharge command information or charge command information is transmitted is specified. Then, the command unit 117 generates stop command information and transmits it to the specified control device 32 (step S5157). Here, upon receiving the stop command information, the control device 32 stops the power conditioner 31. Thereafter, the command unit 117 uncontrollably updates the contents of the control state information stored in the resource information storage unit 135 (step S5158), and the process of step S5156 is executed again. On the other hand, if the identifying unit 116 determines that there is no control device 32 to which the discharge command information or charge command information is transmitted among the control devices 32 installed in the customer facility H located in the supply area (step S5156: No), the power supply mode is switched from the non-control mode to the power suppression mode (step S5159). Thereafter, a series of processes from steps S130 to S136 shown in FIG. 28 are executed for power storage devices 33 and B1 existing in the supply area switched to the power suppression mode.

Further, if the mode management unit 115 determines that the power supply mode is not set to the power suppression mode in step S130 shown in FIG. 28 (step S130: No), the power supply mode is set to the power storage request mode. It is determined that Then, the surplus/deficiency calculation unit 119 calculates the excess power amount (step S138). Next, the specifying unit 116 determines whether or not there is a control device 32 that is not a destination of the discharge command information or the charge command information among the control devices 32 existing in the supply area A1 (step S139). When the specifying unit 116 determines that there is a control device 32 that is not the destination of discharge command information or charge command information among the control devices 32 existing in the supply area A1 (step S139: Yes), a series of steps from step S140 to S144 is performed. processing is executed.

On the other hand, if the specifying unit 116 determines in step S139 that there is no control device 32 that is not the transmission destination of the discharge command information or the charge command information among the control devices 32 existing in the supply area (step S139: No), Based on the excess power amount calculated by the shortage calculation unit 119, it is determined whether the power excess has been resolved (step S5160). Here, if the excess power amount is 0 or less, the identification unit 116 determines that the power excess has been resolved. If the identification unit 116 determines that the power excess has been resolved (step S5160: Yes), the process of step S145 is executed. On the other hand, if the identification unit 116 determines that the excess power has not been resolved (step S5160: No), the mode management unit 115 refers to the power supply mode information stored in the power supply mode storage unit 133 and It is determined whether there is a substation whose power supply mode is set to uncontrolled mode among the substations interconnected with substation A that supplies power to A1 (step S5161). Assume that the mode management unit 115 determines that there is a substation whose power supply mode is set to uncontrolled mode among the substations interconnected with substation A that supplies power to supply area A1 (step S5161: Yes). In this case, the mode management unit 115 switches the power supply mode for the substation to the power storage request mode (step S5162). Subsequently, a series of processes from steps S139 to S143 are executed for the power storage devices 33 and B1 existing in the supply area to which power is supplied from the substation.

On the other hand, suppose that the mode management unit 115 determines that there is no substation whose power supply mode is set to uncontrolled mode among the substations interconnected with substation A that supplies power to supply area A1 (step S5161: Yes), the process of step S145 is directly executed.

Here, FIG. 31 shows the relationship between the power supply mode of substation A that supplies power to supply area A1 and the power supply mode of substation B that is interconnected with substation A and supplies power to supply area A2. I will explain using Assume that the power shortage in the supply area A1 is not resolved when the power supply mode for the supply area A1 is set to the power suppression mode. In this case, if the power supply mode for the supply area A2 is set to the power suppression mode, the power supply mode for the supply area A2 is not switched and is maintained in the power suppression mode. Assume that the power shortage in the supply area A1 is not resolved when the power supply mode corresponding to the supply area A1 is set to the power suppression mode. In this case, if the power supply mode corresponding to supply area A2 is set to uncontrolled mode, the power supply mode corresponding to supply area A2 is switched to power suppression mode. Assume that the power shortage in the supply area A1 is not resolved when the power supply mode corresponding to the supply area A1 is set to the power suppression mode. In this case, if the power supply mode corresponding to supply area A2 is set to power storage request mode, the power supply mode corresponding to supply area A2 is switched to uncontrolled mode. Assume that the excess power in the supply area A1 has not been resolved when the power supply mode corresponding to the supply area A1 is set to the power storage request mode. In this case, if the power supply mode corresponding to supply area A2 is set to uncontrolled mode, the power supply mode corresponding to supply area A2 is switched to power storage request mode. Assume that the excess power in the supply area A1 has not been resolved when the power supply mode corresponding to the supply area A1 is set to the power storage request mode. In this case, if the power supply mode corresponding to the supply area A2 is set to the power storage request mode, the power supply mode corresponding to the supply area A2 is not switched and is maintained in the power storage request mode.

As described above, in the power management device 4001 according to the present embodiment, the power management device has the power supply mode corresponding to the supply area A1 set to the power suppression mode, and the A substation that supplies power to the supply area A1. When the power supply mode corresponding to the supply area A2 corresponding to the B substation connected to the substation is set to power storage request mode, the amount of power supplied from the power storage devices 33 and B1 existing in the supply area A1 to When the amount of power is smaller than the power shortage, the power storage request mode set as the power supply mode corresponding to supply area A2 is canceled. This allows the power output from substation B, which supplies power to supply area A2, to contribute to resolving power shortages in supply area A1, thereby reducing the frequency of power shortages in supply area A1. can.
