As shown in FIG. 4, in normal times, that is, in a state where no trouble such as a power failure has occurred, the operation control device 10 obtains power consumption information from the load device 30 managed by the control unit 11. The power generation information is collected from the power storage device 50 at regular intervals, and the total value of each information is collected as supply and demand information 131 in the data storage unit 13 as the power generation information setting area 131a, the power storage information setting area 131b, and the power consumption information setting. The area 131c is set and managed (steps A1 to A4).

  Next, when a power failure occurs, the power failure level notification device 20 uses the power failure level detection unit 22 to grasp the time from the power failure state to the recovery, and the power failure level corresponding to the time until the recovery (hereinafter referred to as “power failure level information”). ) Is determined (steps B1 and B2). Then, the power failure level notification device 20 notifies the power failure level information from the power failure level transmission unit 21 to the operation control device 10 via the network 60 (step B3).

  When the power failure level information is received by the power failure level receiving unit 12 (step B4), the operation control device 10 notifies the control unit 11, and the control unit 11 starts from the interconnection operation by the power supply from the power supply system. Switching to independent operation is performed (step B5). At this time, the control unit 11 refers to the set value of the supply and demand information 131 of the data storage unit 13 and further uses the power consumption (consumption) for each of the load devices 31 to n set in the load device setting area 132a of the load device information 132.

Independent operation can be performed while efficiently controlling the supply and demand of the management target device (load device 30), and the limited power can be utilized to the maximum. Furthermore, when the time until power failure recovery changes, the power failure level receiving unit 12 that has received the power failure level information from the power failure level transmitting unit 21 notifies the control unit 11 of the information in real time, thereby following the situation change. Self-sustained operation can be performed.

In addition, since the self-sustained operation control system 100 of the power at the time of a power failure uses the same thing as 1st Embodiment, it abbreviate | omits about the detail of the structure.

  First, at the time of power failure recovery, the power failure level notification device 20 notifies the operation control device 10 of power failure recovery from the power failure level transmission unit 21 via the network 60 (steps C1 to C3 above).

  The operation control device 10 that has received the power failure recovery notification at the power failure level receiving unit 12 notifies the power failure level notification device 20 of the supply and demand information 131 when switching from the independent operation to the interconnected operation via the power failure level receiving unit 12. (Steps C4 and C5).

  The power failure level notification device 20 confirms whether or not the interconnection operation is possible from the total value of the supply and demand information 131 collected from the entire area and the supply and demand information managed by the power supply side. The operation control device 10 is notified that the interconnection operation is possible (steps C6, C7, C8).

  Next, the operation control device 10 controls the load device 30, the power generation device 40, and the power storage device 50 under the control of the control unit 11, while adjusting the difference in voltage value, frequency, and phase, and from the independent operation to the interconnection. Switching to operation is performed (steps C9 to C13).
