Abstract:
1. A power operation system comprising: a plurality of photovoltaic power generators connected to an electric power system through one same receiving end and installed in different houses, respectively, each of said plurality of photovoltaic power generators including a solar cell receiving sunlight and outputting electric power, a storage battery for storing said electric power, a communication interface for communication with another photovoltaic power generator, and a battery control unit for controlling storage of said electric power and output of said electric power to said electric power system, at least one of a plurality of said battery control units causing a first photovoltaic power generator included in said plurality of photovoltaic power generators to prioritize output of said electric power to said electric power system over storage of said electric power during a first time period, and causing a second photovoltaic power generator included in said plurality of photovoltaic power generators to prioritize output of said electric power to said electric power system over storage of said electric power during a second time period delayed by a prescribed time period from said first time period.
