    Abstract: The present disclosure is directed to a system and method for controlling an energy storage system. The energy storage system includes a plurality of battery strings connected in parallel with the battery strings having a plurality of batteries connected in series. The method includes determining, via a controller, one or more operating parameters of the energy storage system. The method also includes determining, via the controller, a maximum current rating of one or more of the battery strings. Another step includes estimating, via the controller, a voltage range for the one or more battery strings as a function of the one or more operating parameters and the maximum current rating. The method also includes dynamically controlling the one or more battery strings based on the voltage range so as to prevent over-current recharge or discharge of the parallel battery strings.

    Abstract: Systems and methods for controlling power distribution are provided. The method includes receiving a power command, wherein the power command requests a discharge from one or more BESS units, and wherein the one or more BESS units are housed in one or more temperature controlled rooms. For each of the one or more temperature controlled rooms, a lowest energy remaining of the one or more BESS units in the temperature controlled room is determined; a low threshold is determined based on the determined lowest energy remaining and a floor; a limit is determined based on the determined low threshold; and the limit is assigned to each of the one or more BESS units housed in the temperature controlled room. The method includes causing the power command to be at least partially satisfied by the one or more BESS units based on the assigned limits.

    Abstract: Systems and methods for controlling the temperature of an energy storage system are provided. More specifically, a time period of increased battery temperature attributable to, for instance, charging or discharging of the battery can be identified. A control system can be used to reduce the ambient temperature of a space associated with the battery energy storage devices in the time period prior to or immediately before the period of increased battery temperature. The ambient temperature can be maintained at a nominal ambient temperature at other times.

    Abstract: In one aspect, a method of distributing power among a plurality of energy storage systems in an energy storage farm may generally include receiving a power distribution input associated with a power amount to be received by or delivered from the energy storage farm, determining an initial power value for each energy storage system based at least in part on a state of charge associated with the energy storage system, determining an unallocated power value for the energy storage farm based at least in part on the received power request and the initial power values of the energy storage systems, determining an updated power value for each energy storage system based at least in part on the unallocated power value, and controlling the operation of the energy storage farm such that each energy storage system delivers or receives an amount of power equal to its determined updated power value.
