<P>PROBLEM TO BE SOLVED: To provide a distributed power supply unit which levels a load, without deteriorating the power factor of the power receiving point. <P>SOLUTION: This distributed power supply unit is connected to the load which is connected to a commercial power system at the power receiving point in parallel. In the distributed power supply unit provided with a distributed power supply which stores power; an AC-DC converter which converts the power received from the commercial power system to the DC and charges it to the distributed power supply, and which converts the power stored in the distributed power supply, to the AC and outputs it; and a controller which controls the output from the AC-DC converter, according to a prescribed effective power reference and reactive power reference, and the controller controls the reactive power of the output so that the power factor at the power receiving point becomes a desired value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
