POWER CONTROL SYSTEM AND CONTROL METHOD OF POWER CONTROL SYSTEM

摘要

To establish a system capable of efficient operation control between a plurality of distributed power sources without undermining the versatility of the distributed power sources, a power control system controls a power generation device and other distributed power sources, the power generation device generating power while a current sensor detects forward power flow. The power control system includes: a power control device including an output unit configured to output power supplied from the other distributed power sources, in a state where the power generation device and the other distributed power sources are paralleled off from a grid; and a dummy output system configured to supply a dummy current detectable by the current sensor as a current in the same direction as the forward power flow, using an output from the output unit, wherein the dummy output system includes step-down unit located between the output unit and the current sensor.

1. A power control system that controls a power generation device and other distributed power sources, the power generation device generating power while a current sensor detects forward power flow, the power control system comprising:
a power control device including an output unit configured to output power supplied from the other distributed power sources, in a state where the power generation device and the other distributed power sources are paralleled off from a grid; and
a dummy output system configured to supply a dummy current detectable by the current sensor as a current in the same direction as the forward power flow, using an output from the output unit,wherein the dummy output system includes a step-down unit configured to step down the power supplied from the other distributed power sources located between the output unit and the current sensor.
