PROBLEM TO BE SOLVED: To reduce shortening of the life of a power storage device, when smoothing power by using a plurality of power storage devices having different response performance.;SOLUTION: A smoothing system for smoothing the output from a power generation system includes a first power storage unit, a second power storage unit connected in parallel with the first power storage unit for the load, and having a capacity smaller than that of the first power storage unit, a SOC correction power calculation unit calculating the SOC correction power, i.e., the output power from the smoothing system, for correcting the SOC of the first power storage unit and the SOC of the second power storage unit, based on the SOC of the second power storage unit and the target value thereof, a smoothing unit for calculating a smoothed output by smoothing the sum of the output from the power generation system and the SOC correction power in the time direction, and an output command generation unit generating an output command for the smoothing system from the difference of the smoothed power and the output from the power generation system.;COPYRIGHT: (C)2014,JPO&INPIT
