Abstract: An energy storage system can include an energy storage device, such as a battery energy storage device, having a first terminal and a second terminal. A first unidirectional contactor can be coupled to the first terminal. A second unidirectional contactor can be coupled to the second terminal. The first unidirectional contactor can be coupled to the energy storage device with opposite polarity relative to the second unidirectional contactor. The first unidirectional contactor and the second unidirectional contactor can be controlled based on direction of current flow associated with the energy storage device.

Abstract: Systems and methods for controlling the charge of an energy storage device include determining an estimated energy production prediction for an energy source from a present time to a target time by which an energy storage device is desired to reach a top of charge (TOC) energy level when being charged by the energy source. An available amount of energy for storage at the energy storage device if the energy storage device is charged from the energy source at a first charge rate from the present time until the target time is determined. A present charge rate for the energy storage device is controlled to be the first charge rate when the available amount of energy is less than the energy storage capacity of the energy storage device and to be a second charge rate less than the first charge rate when otherwise.

Abstract: Systems and methods for controlling performance parameters for an energy storage device include providing primary control signals to an energy storage device that indicate at least one operating value in a range defined by at least one set point value for one or more performance parameters of the energy storage device. In one embodiment, an actual performance score for the energy storage device operated in accordance with the primary control signals is determined and compared with a required performance score to determine a performance score evaluation parameter. Additional control signals are then determined and provided to the energy storage device in a manner that adjusts the at least one operating value of the one or more primary control signals relative to the at least one set point value for the one or more performance parameters based at least in part on the performance score evaluation parameter.

Abstract: Systems and methods for controlling an energy storage system are provided. In one embodiment, a method for controlling an energy storage system includes receiving a power demand associated with a grid service operation for an energy storage system and accessing data indicative of a time shift for responding to the power demand. The method includes implementing the time shift in the power demand to obtain a time shifted power demand; and controlling the charge or discharge of one or more energy storage devices in the energy storage system based at least in part on the time shifted power demand.
