Abstract: Provided is a method, device, and system capable of performing control so that the voltage of a grid to which a distributed resource is connected is decreased through charging of an ESS group, performing control so that the voltage of the grid to which the distributed resource is connected is increased through discharging of the ESS group, calculating a voltage control amount through a charge amount and a discharge amount for each ESS group when the voltage of the grid to which the distributed resource is connected is stabilized, and providing a performance incentive for voltage stabilization based on the voltage control amount.
Abstract: The embodiments of the present disclosure relate to an energy storage system (ESS) device that can be used for a moving means such as a construction machine and an electric vehicle, and is configured so that multiple battery packs can be detached to increase a management efficiency of the battery pack.
