Abstract: A plurality of UPSs are connected in parallel between an AC power supply and a load. The UPSs each include a first switch connected between the AC power supply and an AC node. During the first power feeding mode, a control device turns on the first switch, and controls a power conversion device so as to receive AC power from the AC node and generate AC power. During a second power feeding mode, the control device turns off the first switch, and controls the power conversion device so as to receive DC power from a power storage device and generate AC power. When the AC power supply recovers during the second power feeding mode, the control device successively switches the plurality of UPSs to the first power feeding mode by successively turning on a plurality of the first switches each of which corresponds to each of the plurality of UPSs.
