Classification: CPC H | IPC H

Claim 0:
1. A power controller system for controlling an energy storage device comprising:
a memory for storing program instructions; and
a power controller processor, the power controller processor is coupled to the memory and the power controller processor is in communication with at least one power generation system, at least one energy storage system, and at least one power load, the power controller processor is operative to execute program instructions to:
acquire time parameters, including a time window having at least one calculation cycle;
determine a maximum effective energy storage capacity of the at least one energy storage system for the time window;
perform a first sort of the at least one calculation cycle of the time window by sorting in a numerical order according to a ratio of a load demand of the at least one power load to a total available power from the at least one power generation system at each of the at least one calculation cycle;
assign a unique, charge priority value to each of the at least one calculation cycles sorted by the first sort;
determine, responsive to the first sort and starting from a highest charge priority value, a charge power for each calculation cycle until a total charge power satisfies the maximum effective energy storage capacity;
determine, responsive to the first sort and starting from a lowest sorted charge priority value, an available discharge power for the each calculation cycle until a total discharge power exceeds the maximum effective energy storage capacity;
perform, responsive to the total charge power satisfying the maximum effective energy storage capacity and responsive to the total discharge power exceeding the maximum effective energy storage capacity, a second sort in a temporal order of the at least one calculation cycle;
determine, starting from an earliest calculation cycle of the second sort, an available state-of-charge (SOC) of the at least one energy storage system; and
adjust the SOC of the at least one energy storage system for the each calculation cycle organized by the second sort.
