Power supply system, controller of power supply system, method of operating power supply system, and method of controlling power supply system

摘要

A power supply system of the present invention includes: a power generation system (101); a power storage unit (107) configured to supply electric power to the power generation system (101) and an external electric power load (105); and a controller (110) configured to, in a case where it is predicted that at least one of the sum of activation electric power of the power generation system (101) and power consumption of the external electric power load (105) when activating the power generation system (101) and the sum of stop electric power of the power generation system (101) and the power consumption of the external electric power load (105) when stopping the power generation of the power generation system (101) exceeds the upper limit electric power receivable from an electric power system (104), supply the electric power of the power storage unit (107) to at least one of the power generation system (101) and the external electric power load (105) such that the electric power amount supplied from the electric power system (104) does not exceed the upper limit electric power.

主权项

1. A method of controlling a power supply system by executing a control operation, the control operation comprising steps of:
predicting whether or not a sum of activation electric power to activate a power generation system and power consumption of an external electric power load exceeds upper limit electric power receivable from an outside electric power system when activating the power generation system, the upper limit electric power being electric power receivable from the outside electric power system when the outside electric power system is connected to the power supply system; and when it is predicted that the sum exceeds the upper limit electric power, supplying electric power of a power storage unit, while electric power of the outside electric power system is supplied to at least one of the power generation system and the external electric power load, to at least one of the power generation system and the external electric power load such that the electric power supplied from the electric power system does not exceed the upper limit electric power.
