Renewable energy hybrid power generation system, and power generation method therefor

摘要

The present invention relates to a renewable energy hybrid power generation system and a power generation method therefor, wherein the power generation system includes a renewable energy power generation device (RG), a fuel cell system (FC), and a battery energy storage device (BESS). The facility cost for increasing the capacity of the battery is low, and it is not only able to respond to instantaneous load changes, but also maintains the state of charge (SOC) of the battery energy storage device to the maximum, thereby improving the capacity and/or life of the battery. There is this.
