Title: METHOD OF OPERATING A WIND TURBINE SYSTEM INCLUDING AN ENERGY STORAGE SYSTEM
Abstract:
Systems and methods for operating an energy storage system in a wind turbine system are provided. A wind turbine system can include a wind turbine, a power conversion system operably coupled to the wind turbine and an AC line bus, and an energy storage system coupled to the AC line bus. The energy storage system can include a transformer, a power converter, and an energy storage device and can be configured to store and provide power generated by the wind turbine. The method can include operating the wind turbine system to generate power, determining one or more operating parameters for the wind turbine system, determining an operating mode based on the one or more operating parameters, and controlling the wind turbine system based at least in part on the operating mode. Controlling the wind turbine can control a power flow into or out of the energy storage system.
