It is in. SOLUTION: In a combined wind / power storage system including a plurality of wind power generators 1a, 1b, and power storage devices 5a, 5b and power converters 6a, 6b installed in parallel to the wind power generators, synthesis of the wind power generators is performed. A current detecting means 8a, a voltage detecting means 9a of the power system 18, a means 8b for detecting a current input / output by the power converter, and an output power P of the wind power generator. means 6a for calculating w, Qw from the system voltage and the combined current detection value of the wind power generator, and input / output power Pc, Means 6b for calculating Qc from the system voltage and the current detection value of the power converter, and a control device 11a for generating a pulse signal for controlling the power converter are provided. The output power of the wind power generator and the input / output power of the power converter are provided. Is used for power feedback of the control system of the power converter.
