<P>PROBLEM TO BE SOLVED: To provide a DC feeding system that controls a DC feeding section within a predetermined voltage range. <P>SOLUTION: Power storage equipment is connected to the DC feeding section for supplying DC power from a commercial power distribution system to a load via a power converter. A voltage at the DC feeding section is monitored. The power converter is controlled to supply power from the commercial power distribution system to the DC feeding section when the voltage at the DC feeding section falls below a predetermined voltage range and to supply power from the DC feeding section to the commercial power distribution system when the voltage at the DC feeding section exceeds the predetermined voltage range. <P>COPYRIGHT: (C)2012,JPO&INPIT |
