ENERGY SUPPLY SYSTEM, AND DEVICE AND METHOD FOR CONTROLLING THE SAME

Japanese Patent JP2022037494

A

To surely mitigate the fluctuation of a power transmission amount in an energy supply system.SOLUTION: An energy supply system 1 includes: a regenerative energy power generation device 2 which transmits at least a part of power, generated from regenerative energy, to a power system 16; a storage battery 4 which can be charged with power generated in the regenerative energy power generation device 2 and can transmit at least a part of the charged power to the power system 16; and a control unit 30 which controls the storage battery 4 in a manner that a change rate of the power transmission amount to the power system 16 does not exceed a permissible change rate, and calculates necessary SoC which is necessary to maintain the change rate at the permissible change rate or smaller by the power transmission from the storage battery 4 when the power generation of the regenerative energy power generation device 2 stops and the power transmission amount to the power system 16 falls to zero, so as to control the storage battery 4 to reduce the power transmission amount, when the necessary SoC exceeds the SoC of the present state.SELECTED DRAWING: Figure 1
