The disaster information management device 50 then outputs the disaster information stored in the storage device 52 to the management server 10 via the communication device 53. The disaster information also includes the predicted time of future disaster occurrence.

Figure 6 is a block diagram of the process performed by the management server 10 to maintain a balance between power demand and supply.

In the power management system 1, in order to maintain a balance between the demand and supply of electricity in the management area 100 during a disaster, external data 601, generator information 602, disaster power demand data 603, at-home evacuation personal data 604, collective evacuation shelter data 605, town management data 606, and supply target setting data 607 are input to the management server 10 via a network NW or the like. The external data 601 includes, for example, an external support plan, power outage restoration information, and weather information. The generator information 602 includes, for example, information on the amount of power generated by the generator 34 and the amount that can be supplied. The disaster power demand data 603 includes, for example, data on the amount of power required by each facility, such as the apartment building 20 and collective evacuation shelter 40 in the management area 100, during a disaster. The at-home evacuation personal data 604 includes data on residents (disaster victims) who have evacuated to the dwelling unit 200. The collective evacuation shelter data 605 includes data on the electrical appliances 44 that should be used preferentially in the collective evacuation shelter 40 in the event of a disaster, data on the number of disaster victims evacuated to the collective evacuation shelter 40, and the like. The town management data 606 includes data on the number of people in the collective evacuation shelter 20, for example, when the management area 100 is treated as one town and the entrance and exit of residents to the collective evacuation shelter 20 is managed by a surveillance camera or the like in the event of a disaster. The supply target setting data 607 includes data on the service level that ranks the priority of the power supply destination according to the importance in the event of a disaster, the power supply time to the power supply destination set according to the service level, and the standby time from the occurrence of a power outage to the start of power supply to the power supply destination set according to the service level. Note that the data on the service level, the power supply time, and the standby time included in the supply target setting data 607 are not limited to those that are set in advance, and may be set as needed according to the type and scale of the disaster that has occurred.

The server control device 11 of the management server 10 has a power restoration prediction unit 111, a power generation prediction unit 112, a power demand prediction unit 113, a victim data list generation unit 114, an evacuation pattern generation unit 115, a load distribution plan calculation unit 116, an individual usage limit calculation unit 117, a supply and demand balance control command generation unit 118, etc. In addition, the storage device 12 of the management server 10 stores a priority supply database 121 that collects information on targets to which power should be supplied preferentially in the event of a disaster.

The power restoration prediction unit 111 predicts the time when power supply from the power grid 60 will be restored if a power outage occurs in the power grid 60 during a disaster. The power generation prediction unit 112 predicts the amount of power required by the power generation facility 30. The power demand prediction unit 113 predicts the demand for power during a disaster. The victim data list generation unit 114 generates a data list that collects information about victims.

The evacuation pattern generation unit 115 generates evacuation patterns for each disaster victim, such as who will evacuate, where, and for how long, based on various information from the priority supply database 121, the power restoration prediction unit 111, the power generation prediction unit 112, the power demand prediction unit 113, and the disaster victim data list generation unit 114. The evacuation pattern generation unit 115 receives a command signal generated by the supply and demand balance control command generation unit 118 to control the balance of supply and demand of electricity during a disaster, and feeds it back to the generation of evacuation patterns. The load distribution plan calculation unit 116 calculates a plan for load distribution (power distribution) to the collective evacuation shelter 40 and the dwelling unit 200, etc., based on the power consumption at the collective evacuation shelter 40 and the dwelling unit 200, the number of evacuees, and loads (electrical equipment 203, 204, 44 and power equipment 24) that should be given priority for power supply to medical equipment, etc. The individual usage limit amount calculation unit 117 calculates the limit amount of electricity that can be used in the collective evacuation shelter 40, the dwelling unit 200, etc., based on the load distribution plan calculated by the load distribution plan calculation unit 116. The supply and demand balance control command generation unit 118 generates a command to control the balance of supply and demand of electricity in the event of a disaster, based on the calculation results of the load distribution plan calculation unit 116 and the calculation results of the individual usage limit amount calculation unit 117.

The supply and demand balance control command generation unit 118 outputs the generated command signal for controlling the balance of power supply and demand during a disaster to, for example, the apartment building 20, the power generation facility 30, and the collective evacuation shelter 40. In the apartment building 20, the home control device 21 performs, for example, remote shutoff control of the smart meter 201, control of the electrical appliances 203 and 204 by the HEMS 205, and control for displaying information such as the upper limit of the available electrical energy and the remaining available electrical energy on the display device 206. In the power generation facility 30, the power generation control device 31 performs, for example, power generation control of the generator 34 to generate the required amount of electrical energy. In the collective evacuation shelter 40, the evacuation shelter control device 41 performs, for example, control of the electrical appliances 44.

In the power management system 1 according to the embodiment, for example, in the event of a disaster, the remaining amount of power in the power storage device 25 installed in the apartment building 20 and the amount of available power in each of the dwelling units 200A, 200B, 200C, and 200D are made visible, and the power supply to each of the dwelling units 200A, 200B, 200C, and 200D is controlled.

In the power management system 1 according to the embodiment, when the power grid 60 is powered out during a disaster and the power generation facility 30 supplies power to each of the multiple dwelling units 200A, 200B, 200C, and 200D of the apartment building 20, the smart meters 201A, 201B, 201C, and 201D and the HEMS 205A, 205B, 205C, and 205D are controlled to adjust the amount of available power for each of the multiple dwelling units 200A, 200B, 200C, and 200D. Information such as the upper limit of the amount of available power during a disaster and the remaining amount of available power for each of the multiple dwelling units 200A, 200B, 200C, and 200D is displayed on the display devices 206A, 206B, 206C, and 206D and the mobile information terminals of the residents by the HEMS 205A, 205B, 205C, and 205D.

The amount of electricity required in the event of a disaster for each of the multiple dwelling units 200A, 200B, 200C, and 200D is predicted based on the scale of the disaster, electricity demand in peacetime, the importance of the power facilities 24, weather, the number of residents, and personal data of the residents, and a fair distribution of electricity is planned based on specified conditions.

For example, in the event of a large-scale earthquake occurring as a disaster, power is supplied to the lighting and elevators, which are power equipment 24 in the apartment building 20, as these are of high importance during an evacuation, while the power supply to the elevators, which are prohibited from use during an evacuation and are of low importance, is stopped. Then, the amount of power that is no longer required to be supplied to the elevators is distributed to the multiple dwelling units 200A, 200B, 200C, and 200D.

In addition, the amount of electricity to be distributed may be increased for dwelling units 200 with a larger number of residents according to the number of residents in each of the multiple dwelling units 200A, 200B, 200C, and 200D. The amount of electricity to be distributed may also be calculated according to the age composition of the residents of the dwelling units 200. For example, the amount of electricity to be distributed may be increased according to the number of elderly people (for example, residents aged 65 or older) in the dwelling unit 200, assuming that medical equipment is likely to be used in the dwelling unit 200 that includes elderly residents. In addition, for example, depending on the scale of the disaster, it is considered that some of the residents of the apartment building 20 evacuate to the collective evacuation shelter 40 or stay at their homes (dwelling units 200). In addition, in each of the multiple dwelling units 200A, 200B, 200C, and 200D, it is considered that all households evacuate to the collective evacuation shelter 40, or some of the residents of the household evacuate to the collective evacuation shelter 40 and the remaining residents stay at their homes. Therefore, in the event of a disaster, a camera or the like may be used to detect residents passing through the entrances and exits of the apartment building 20, and it may be determined which dwelling unit 200 the detected resident belongs to. The number of residents predicted to remain in each of the multiple dwelling units 200A, 200B, 200C, and 200D may then be calculated, and the amount of electricity distributed to dwelling units 200 with a greater number of residents remaining there may be increased.

In addition, in the power management system according to the embodiment, it may be possible for power to be exchanged between the multiple dwelling units 200A, 200B, 200C, and 200D. This allows, for example, a dwelling unit 200 with a relatively large amount of remaining usable power displayed on the display device 206 to supply power to a dwelling unit 200 with a relatively small amount of remaining usable power displayed on the display device 206, thereby allowing power to be shared between the dwelling units 200 in the event of a disaster.

In the power management system 1 according to the embodiment, power distribution predictions and actual results of power usage are shared and made visible among the dwelling units 200, making it possible to reduce wasteful power consumption and promote the exchange of power among the dwelling units 200. In addition, for dwelling units 200 that exceed the upper limit of the amount of power that can be used in the event of a disaster, a notification is sent to the display device 206 or the resident's mobile information terminal, and power control can be performed, such as automatically cutting off the power supply by operating a circuit breaker that can be operated from the HEMS 205 and is installed in the distribution board 202 of the dwelling unit 200.

Figure 7 shows a power management control routine that is implemented when the server control device 11 in the power management system 1 acquires information regarding the occurrence of a disaster. The power management control routine shown in Figure 7 is implemented in cooperation between the server control device 11 and the home control device 21, and is composed of a control routine executed by the server control device 11 and a control routine executed by the home control device 21. The power management control routine shown in Figure 7 also shows power management for multiple dwelling units 200A, 200B, 200C, and 200D of the apartment building 20 in the event of a disaster.

First, the server control device 11 acquires information about the occurrence of a disaster from the disaster information management device 50 via the network NW or the like (step S1). Next, the server control device 11 calculates the upper limit of the amount of electricity to be distributed to the multiple dwelling units 200A, 200B, 200C, and 200D of the apartment building 20 (step S2). Next, the server control device 11 outputs a signal related to the upper limit of the amount of electricity to be distributed to the multiple dwelling units 200A, 200B, 200C, and 200D to the housing control device 21 via the network NW or the like (step S3). Then, the server control device 11 ends this control routine. Note that the signal related to the upper limit of the amount of electricity also includes a command signal to cut off the power supply when the amount of electricity used exceeds the upper limit.

Next, the home control device 21 receives a signal regarding the upper limit of the amount of electricity to be distributed to the multiple dwelling units 200A, 200B, 200C, and 200D (step S4). Next, the home control device 21 causes the HEMS 205 installed in the dwelling unit 200 to display the amount of electricity available and the amount of electricity used in the dwelling unit 200 on the display device 206 based on the upper limit of the amount of electricity (step S5). Next, the home control device 21 causes the HEMS 205 installed in the dwelling unit 200 to determine whether the amount of electricity used in the dwelling unit 200 has exceeded the upper limit (step S6). If the HEMS 205 determines that the amount of electricity used in the dwelling unit 200 has not exceeded the upper limit (No in step S6), the home control device 21 returns to step S5. On the other hand, if the HEMS 205 determines that the amount of power used in the dwelling unit 200 has exceeded the upper limit (Yes in step S6), the home control device 21 notifies the display device 206 by the HEMS 205 that the amount of power used has exceeded the upper limit (step S7). Next, the home control device 21 operates a circuit breaker provided in the distribution board 202 of the dwelling unit 200 by the HEMS 205 to cut off the power supply to the dwelling unit 200 (step S8). The home control device 21 then ends this control routine.

In the power management system 1 according to the embodiment, the amount of power available and the amount of power used during a disaster are displayed on the display device 206 and made visible, so that the resident can be encouraged to use power within the range of the amount of power to be distributed with the upper limit set in the dwelling unit 200. In addition, in the power management system 1 according to the embodiment, by notifying the dwelling unit 200 of the power cut before cutting off the power supply to the dwelling unit 200, it is possible to obtain power from other dwelling units 200 before the power supply to the dwelling unit 200 is cut off. In addition, in the power management system 1 according to the embodiment, by cutting off the power supply to the dwelling unit 200 that has exceeded the upper limit of the amount of power to be distributed during a disaster, it is possible to prevent a specific dwelling unit 200 from using too much power alone, and to distribute power fairly to the multiple dwelling units 200A, 200B, 200C, and 200D.
