Battery charge and discharge power control in a power grid

Abstract

According to some embodiments, system and method are provided comprising determining a maximum storage capacity of an energy storage system for a time window; performing a first sort of cycles by sorting in numerical order according to a ratio of a load demand to a total available power from a power generation system at each cycle of time window; assigning a unique, charge priority to each cycle; determining, starting from a highest charge priority, a charge power for each cycle until a total charge power satisfies the maximum storage capacity; determining, starting from a lowest sorted charge priority, an available discharge power for each cycle until a total discharge power exceeds the maximum storage capacity; performing a second sort in a temporal order of the cycles; determining, starting from an earliest cycle, an available state-of-charge (SOC) and adjusting the SOC of the energy storage system for each cycle.
