Abstract: A management apparatus periodically transmits information for setting a first voltage range and a second voltage range smaller than the first voltage range to a distribution power supply apparatus. The distribution power supply apparatus removes, from an interconnection point voltage at an interconnection point with the distribution system, a voltage fluctuation component with a cycle shorter than a cycle in which the information is transmitted from the management apparatus to thereby generate a voltage command value of the interconnection point, and performs reactive power control for eliminating a voltage deviation of the interconnection point voltage with respect to the voltage command value. In the reactive power control, the generation of the reactive power is started when an absolute value of the voltage deviation exceeds the first voltage range, and the reactive power is adjusted until the absolute value falls below the second voltage range.
