[Object of the Invention] An object of the present invention is to provide a wind power generation system comprising a wind turbine power generation mechanism and a charge/discharge device, wherein charging of the charge/discharge device with output power of the wind turbine power generation mechanism works cooperatively with discharging of the power through the charge/discharge device to a distribution system so as to smooth the power output to the distribution system, and wherein smoothing of the power output to the distribution system is stably achieved without requiring capacity increase of the charge/discharge device. [Disclosure of the Invention] A wind power generation system comprises a wind turbine power generation mechanism and a charge/discharge device, wherein charging of the charge/discharge device with output power of the wind power generation mechanism works cooperatively with discharging of the power through the charge/discharge device to a distribution system so as to smooth the power output to the distribution system, and further comprising a pumped-storage power generation mechanism, and wherein pumping up of water by the pumped-storage power generation mechanism supplied with power from the charge/discharge device or hydraulic power generation using a head of pumped water by the pumped-storage power generation mechanism and transmission of output power to the charge/discharge device is selectively carried out at a relatively short predetermined time cycle of a few tens of seconds to a few minutes based on mean wind power generation output value during a preceding time cycle and power storage quantity of the charge/discharge device at the end of the preceding time cycle. |
