1. A hybrid power generation system, comprising:
a renewable energy power generation device capable of generating power by using renewable energy;
a rotary power generation device connected to an alternating-current power system in common with the renewable energy power generation device, the rotary power generation device being capable of generating power such that an output fluctuation of the renewable energy power generation device is reduced; and
a control device for controlling the rotary power generation device such that a rotation speed of the rotary power generation device reaches a target rotation speed,
wherein the hybrid power generation system comprises: a fluctuation determination part for determining whether a fluctuation amount of the renewable energy supplied to the renewable energy power generation device or an output of the renewable energy power generation device exceeds a predetermined value; and
a correction value calculation part for calculating a correction value of a control parameter based on the fluctuation amount, and
wherein the control device controls the rotary power generation device based on the control parameter which is obtained by adding, as a feedforward component, to the control parameter on a feedback control loop of the control device, the correction value calculated by the correction value calculation part, if the fluctuation determination part determines that the fluctuation amount of the renewable energy supplied to the renewable energy power generation device or the output of the renewable energy power generation device exceeds the predetermined value.
