    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, an energy storage system can include a plurality of energy storage units and a plurality of buses. The energy storage system can further include a control system that can be configured to receive one or more signals indicative of a voltage associated with each energy storage unit of the plurality of energy storage units. The control system can be configured to send one or more command signal to selectively couple each energy storage unit to one of the plurality of buses based at least on the voltage associated with the energy storage unit.

    Abstract: Power converters that can allow for the transfer of DC power between a ground-referenced bus and a floating system are provided. In one embodiment, the power converter includes a ground-referenced DC bus associated with a DC voltage. The power converter further includes a first switching element, a second switching element, and a third switching element coupled in series between the ground-referenced DC bus and a ground reference. The power converter further includes a floating system associated with a floating DC voltage. The floating system can include a first terminal coupled to a first node between the first switching element and the second switching element. The floating system can further include a second terminal coupled to a second node between the second switching element and the third switching element.
