Abstract: Systems and methods for controlling the state of charge of an energy storage system used in conjunction with a renewable energy source or other power generation system are provided. More particularly, a future output requirement of the energy storage system can be predicted based at least in part on data indicative of anticipated conditions, such as weather conditions, wake conditions, or other suitable conditions. A control system can adjust a state of charge setpoint from a nominal setpoint (e.g. 50%) to an adjusted setpoint based at least in part on the future output requirement. In this way, the energy storage system can better accommodate the output requirements of the energy storage system during varying weather conditions.

Abstract: Systems and methods for controlling operation of a power converter based on grid conditions are provided. In particular, a first gating voltage can be applied to a switching element of a power converter associated with a wind-driven power generation system. The first gating voltage can be greater than a threshold voltage for the switching element. A grid event associated with an electrical grid coupled to the power generation system can be detected. A second gating voltage can be applied to the gate of the switching element during the detected grid event. The second gating voltage can be greater than the first gating voltage.

Abstract: Systems and methods for cooling one or more electrical components of a current conversion device of a renewable energy power system (e.g. a wind turbine or a solar power system) are disclosed. In one embodiment, the system includes an immersion tank comprising a cooling medium, a heat exchanger, and a pumping device. One or more of the electrical components are at least partially submerged within the cooling medium, which has a predetermined dielectric constant. The heat exchanger is in fluid communication with the cooling medium of the immersion tank. Thus, the pumping device is configured to circulate the cooling medium between the immersion tank and the heat exchanger to remove heat from the one or more electrical components.
