Wind Power Generation System and Method for Additional Installation of Wind Power Generator Therein

摘要

The present invention provides a wind power generation system capable of suppressing an increase in output variation involved in additional installation of a wind power generator without the need for a large storage battery capacity. For example, an output variation rate at a predetermined period of an existing wind power generator in an existing wind-power generating station is determined in advance, and charge/discharge control for a storage battery device is performed to reduce an output variation in a system output of the existing wind power generator so that an output variation rate of the wind-power generating system after the additional installation of the wind power generator does not exceed the determined output variation rate of the existing wind power generator.
