PHOTOVOLTAIC POWER GENERATION SYSTEM, CONTROL METHOD AND CONTROL PROGRAM FOR PHOTOVOLTAIC POWER GENERATION SYSTEM

摘要

A photovoltaic power generation system includes a photovoltaic power generator including a plurality of PV modules, and a PV inverter that connects an output by the photovoltaic power generator to a power grid. The ratio of a rated output by the photovoltaic power generator defined by a rated output by the PV modules relative to a rated output by the PV inverter is equal to or greater than 140%. The photovoltaic power generation system further includes a battery unit, a battery inverter that connects an output by the battery unit to a power grid, and a controller that adjusts an output by the battery unit in such a way that an output by the battery inverter becomes equal to or greater than a preset electric power together with an output by the PV inverter.
