Power operation system, power operation method, photovoltaic power generator and controller

摘要

A power operation system including a plurality of photovoltaic power generators connected through one same receiving end to an electric power system is provided. Each of the photovoltaic power generators includes a solar cell receiving sunlight and outputting electric power, and a storage battery for storing the electric power. The power operation system includes a limiting unit limiting storage of electric power by a first photovoltaic power generator among the plurality of photovoltaic power generators in a first time period, and limiting storage of electric power by a second photovoltaic power generator among the plurality of photovoltaic power generators in a second time period different from the first time period.
