POWER SUPPLY SYSTEM, DISTRIBUTED POWER SOURCE SYSTEM, MANAGEMENT APPARATUS, AND POWER SUPPLY CONTROL METHOD

摘要

A power supply system comprises a plurality of distributed power source systems capable of supplying powers to loads 400 by performing an interconnection operation in parallel with grid 10 or an offline self-sustained operation. SOFC system 300 detects an abnormal state of the power supplied to loads 400. SOFC system 300 eases the abnormality detection conditions during the self-sustained operation than during the interconnection operation.
