Power operation system, power operation method and photovoltaic power generator

摘要

Each of a plurality of photovoltaic power generators includes a solar cell, a storage battery, a communication interface for communication, and a battery control unit for controlling storage of electric power and output of electric power to an electric power system. The battery control unit of the first photovoltaic power generator included in the plurality of photovoltaic power generators causes the first photovoltaic power generator to prioritize output of the electric power to the electric power system over storage of the electric power during the first time period, and causes the second photovoltaic power generator included in the plurality of photovoltaic power generators to prioritize output of the electric power to the electric power system over storage of the electric power during the second time period delayed by a prescribed time period from the first time period, through the communication interface.

主权项

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.
