Abstract
An electrical distribution system is configured to supply electric power to an electric load and includes a feeder, a battery energy storage system, an electrical switchgear device and an electronic controller. The switchgear device is configured to selectively connect the connection point to the feeder, wherein the electronic controller is configured to: detect an electric fault representative of a power loss event on the grid power source; upon detecting an electric fault, automatically open the electrical switchgear device to disconnect the grid power source from the feeder; and ensure that the battery system supplies electric power to the electric load while operating in a virtual-synchronous generator control mode.
