Claim:
1. A power connection control system configured to function in conjunction with energy provision equipment to be linked to an electric power system, the energy provision equipment configured to supply electric power to electrical appliances that a consumer owns, the power connection control system comprising: a connection control apparatus comprising an opening/closing device capable of connecting or disconnecting the electric power system and the consumer, and that, when a power outage occurs in the electric power system, disconnects the electric power system and the consumer from each other by the opening/closing device based on a command received from outside; and a power supply control apparatus that, when the power outage occurs in the electric power system, supplies electric power from the energy provision equipment to the electrical appliances; an outage management apparatus that, when the power outage occurs in the electric power system, transmits to said connection control apparatus a parallel-off command for disconnecting the electric power system and the consumer from each other, and, at the time of restoration from the power outage, transmits to said connection control apparatus a linkage command for linking the electric power system and the consumer to each other, wherein said connection control apparatus, when restoration of power from the power outage in an electric power system is detected, transmits to said outage management apparatus a linkage operation time representing the time from receiving a linkage command, for linking the consumer to the electric power system, to enabling linkage of the units of energy provision equipment with the electric power system and a predicted amount of reverse power flow representing a surplus amount of electric power computed from a predicted amount of electric power generated from the energy provision equipment at the time of linkage and a predicted total power consumption of the electrical appliances at the time of linkage, wherein said outage management apparatus schedules a time to transmit the linkage command for each consumer based on the linkage operation time and the predicted amount of reverse power flow, and transmits the linkage command to said connection control apparatus according to the scheduled time.
