Abstract:
A battery energy storage system control system, including: logic coupled to a photovoltaic station and an energy storage system and executing a photovoltaic station capacity firming algorithm operable for making a combined output of the photovoltaic station and the energy storage system substantially constant such that power swings on an associated feeder system are avoided; logic coupled to the photovoltaic station and the energy storage system and executing a voltage support algorithm operable for holding point of common coupling voltage and phase values substantially equal to substation voltage and phase values via power injection or removal; and logic coupled to the photovoltaic station and the energy storage system and executing an energy time shift algorithm operable for storing energy during periods of relatively low demand and providing energy during periods of relatively high demand.
