FUEL CELL SYSTEM, FUEL CELL SYSTEM CONTROL METHOD, AND BUILDING that suppresses peak power consumption below maximum generated power

摘要

To provide a fuel cell system that can appropriately prevent the peak of power consumption from exceeding the maximum power generation by the fuel cell. When it is necessary to increase the power consumption of the fuel cell, the power load operated by the power, and the power load, the request control unit that transmits the request information in advance, and the power load when the request information is received from the request control unit On condition that the fuel cell can further supply power to the fuel cell, the fuel cell control unit that transmits a permission notification that the power consumption may be increased, and on the condition that the permission notification is received from the fuel cell control unit A load control unit that increases the power consumption of the load, and the fuel cell control unit reduces power consumption to the load control unit when it is necessary to reduce the power consumption of the power load in order to keep the total power consumption value small. Instruct to lower. When the load control unit receives an instruction to reduce power consumption from the fuel cell control unit, the load control unit reduces power consumption.
