METHOD FOR OPERATING ENERGY SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method and a device which assures a sustaining operation of an energy storage unit, operates an energy supply system capable of lowering the whole operation cost or controls the energy supply system capable of designing a more compact energy supply system.SOLUTION: An energy supply system includes an energy storage unit and an energy production unit. Based on an energy flow rate which can be supplied by the system and an energy flow rate externally required from the system, an operation cost of the energy supply system can be calculated with respect to all possible values of the parameters beforehand. Calculated parameters can be housed on an arrangement of a device which undertakes execution and the energy supply system can be operated so as to assure that a prescribed (not zero) amount of energy flow rate can be supplied by the energy storage unit at any time.
