STAND-ALONE POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a stand-alone power supply system capable of reducing an installation cost.SOLUTION: A stand-alone power supply system calculates demand prediction data for a load device and power generation output prediction data for a natural energy power generation device using weather prediction data. If a storage battery is anticipated to be charged beyond the maximum charge power of the storage battery from the demand prediction data and the power generation output prediction data, the stand-alone power supply system suppresses power generation output from the natural energy power generation device. If a storage battery is anticipated to be discharged beyond the maximum discharge power of the storage battery from the demand prediction data and the power generation output prediction data, the stand-alone power supply system suppresses power consumption of a load for adjustment.
