An energy management method for an energy supply system which includes at least an energy storage, a load and a generator with power dependent efficiency is provided. The method includes: calculating two time variant parameters indicating a discharge lower limit and an upper charge limit, respectively, of the energy storage, based on optimization using different kinds of prediction; and controlling, in a real time manner, charging and discharging of the energy storage and operation of the generator, with a certain priorities given to various power sources, such that state of charge of the energy storage is controlled within a region between the discharge lower limit and the upper charge limit. When a grid power is available, blackout duration probability function is predicted and used to calculate the discharge lower limit and the upper charge limit. |
