Abstract
An energy storage system for a substation on an electrical power network is provided. The energy storage system is coupled to receive and store electrical power. The stored electrical power may then be used to either charge vehicles or meeting the needs of other discretionary or interruptible loads with an electric propulsion, or to provide electrical power a feeder connected to essential service loads such as police stations, hospitals and traffic control. In one embodiment, the substation also utilizes the energy storage system in a peak shaving mode of operation.
