- the unit 122 determines that the distributed power source 111 has stopped, that is, the receiving condition has been fulfilled when there is an abnormal recording in the power supply state (B-1) or when normal recording has not been performed for a certain period of time. It may be detected.
- the power management device 120 fulfills the receiving condition, that is, when it becomes necessary for the power management device 120 to supply power to the consumer management device 110 based on the power interchange contract, the power management device 120 The following processes of S304 to S306 are performed.
- the information control unit 122 of the power management device 120 determines one or more other customer management devices 110 (power transmission sources) that should supply power to the consumer management device 110 (power transmission destination) that fulfills the receiving condition. (S304).
- the power transmission source determination method is the same as step S104 of the first embodiment.
- the information control unit 122 of the power management apparatus 120 instructs the control unit 112 of the consumer management apparatus 110 determined as the power transmission source to supply the allocated power amount (S305).
- the upper limit of the amount of power allocated to each power transmission source is the contract supply power amount of each power transmission source.
- the power transmission source control unit 112 secures the allocated power amount by adjusting the output of the distributed power source 111 and the load 112 and transmits power to the power control unit 123 of the power management device 120. To do.
- the power control unit 123 of the power management apparatus 120 transmits the power supplied from the power transmission source to the consumer management apparatus 110 that is the power transmission destination (S306).
- the power supply based on the power interchange contract with the power transmission destination is continued until the receiving condition of the power transmission destination is not satisfied.
- the power transmission destination can continuously receive the contract received power amount until recovery of the distributed power source 111 is detected by the life and death confirmation.
- the power management system 120 can select the power transmission destination based on the priority defined in the power transmission destination priority table (C-2) when it is necessary to give priority to the power transmission destination. As described in the first embodiment.
- the priority in the power transmission destination priority table (C-2) can be set higher than that of the user. Thereby, for example, it is possible to perform more flexible power accommodation according to the contract contents, such as preferential treatment of a consumer who is evaluated to have a greater contribution to the power accommodation system 100.
- the consumer management device 110 reliably receives the contract received power amount when the receiving condition is satisfied, instead of limiting the power generation amount in normal times when the supply condition is not satisfied. be able to. Thereby, it is possible to construct a power network that is resistant to power failure and the like.

- the controller can determine an optimal power transmission path using a known network path control technique.
- the controller can perform route determination using the homogeneity of power. That is, when power amount X is to be transmitted from power router A to B and power amount Y (Y ⁇ X) is to be transmitted from power router A to B, only the difference power XY is transmitted between these power routers AB. That's fine.
- the contracted power transaction may not always match the actual power transmission amount and power transmission route.
- a power transmission network using a power router not only a power transmission / reception point but also a power transmission route between them can be set.

- the power management apparatus 220 includes a management information storage unit 121 and an information control unit 222.
- the information control unit 222 receives power network information described later from each power router 230, and as power supply status (B-1) and distance (B-2) A function to record in the power network table 1212; a function to calculate an optimum power transmission path at the time of power interchange; a function to notify each power router 230 of the power transmission path and the amount of power transmitted; and a function to receive a power transmission result from each power router 230 Have. That is, the information control unit 222 functions as a controller for the power router 230.
- the power router 230 is connected to the backbone system and the plurality of customer management devices 110 so as to be able to transmit and receive power through a transmission line.
- the information control unit 222 and the customer management device 110 are connected to be communicable with each other by wire or wirelessly.
- the power router 230 may be connected to another power router 230 so as to be able to transmit and receive power through a power transmission line, and may be connected to be communicable via wire or wirelessly.
