Zusammenfassung:	A power fluctuation mitigation system includes a first converter coupled to an AC power supply to perform AC-to-DC conversion, an inverter coupled to the first converter via a DC intermediate condenser to perform DC-to-AC conversion to supply power to an AC load, a second converter coupled to the AC power supply to perform AC-to-DC conversion, an electric storage device configured to be charged by a DC output power of the second converter, and a DC/DC converter coupled between the DC intermediate condenser and the electric storage device to perform DC power conversion, wherein a DC power obtained by activating the DC/DC converter is supplied to the DC intermediate condenser as a compensating power upon a change in an output of the inverter occurring due to fluctuation of the AC load.
