PROBLEM TO BE SOLVED: To attain output variation compensation effect surely through charge/discharge of a power storage unit by preventing the storage electric energy of the power storage unit from sticking to an upper limit or a lower limit for a long term.;SOLUTION: In the controller 150 of a power stabilization system 100 for preventing variation in effective power of a power system 110 connected with a wind generator 130 by compensating output variation of the wind generator 130 with the storage electric energy Es of a power storage unit 140, a correction signal operating section 156 for delivering a correction signal Pc to the control route of an effective power detecting section 151, a compensation target value operating section 152, an compensation power operating section 153, a power converter control section 154, and a power converter 141 operates the correction signal Pc based on the storage electric energy Es of a power storage unit 140 in the direction for discharging storage power when the storage electric energy Es approaches an upper limit value, and in the direction for charging storage power when the storage electric energy Es approaches a lower limit value.;COPYRIGHT: (C)2008,JPO&INPIT
