POWER SUPPLY SYSTEM, DISTRIBUTED POWER SOURCE SYSTEM, ADMINISTRATION DEVICE, AND POWER SUPPLY CONTROL METHOD

摘要

Provided is a power supply system, comprising a plurality of distributed power source systems with which it is possible to supply power to loads (400) by carrying out either parallel connected operation with a grid (10) or isolated operation not in parallel with the grid (10). An SOFC system (300) detects a malfunction in a state of power supplied to the loads (400). The SOFC system (300) relaxes a condition of the detection of the malfunction when in isolated operation beyond the degree when in the connected operation.
