Wind power generation system and method for adding wind power generator in wind power generation system

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 200 in an existing wind-power generating station is determined in advance, and charge/discharge control for a storage battery device 300 is performed to reduce an output variation in a system output of the existing wind power generator 200 so that an output variation rate of the wind-power generating system after the additional installation of the wind power generator 100 does not exceed the determined output variation rate of the existing wind power generator 200.
