PROBLEM TO BE SOLVED: To securely obtain a compensation effect for output fluctuations caused by charging and discharging of a power storage device, by preventing stored electric energy of a power storage device from being fixed to an upper limit value or a lower limit value over a long period of time.;SOLUTION: A controller 150 of a power stabilizing system 100 prevents fluctuations in effective power of a power system 110 to which a wind power generator 130 is connected, by compensating output fluctuations of the wind power generator 130 with stored electric energy Es of a power storage device 140. In the controller 150, a correction signal calculating part 156 which gives a correction signal Pc to a control route of an effective power detecting part 151, a compensation target value calculating part 152, a compensation power calculating part 153, a power converter control part 154, and a power converter 141 calculates a correction signal Pc based on the stored electric energy Es of the power storage device 140, in the direction of discharging stored power when the stored electric energy Es approaches the upper limit value, and in the direction of charging the stored power when the stored electric energy Es approaches the lower limit value.;COPYRIGHT: (C)2011,JPO&INPIT
