Abstract
Systems and methods for operating an energy storage system in a doubly fed induction generator wind turbine system are provided. An energy storage system can include a transformer configured to transform AC power from a first voltage to AC power at a second voltage and a bi-directional AC to DC power converter coupled to the transformer. The bi-directional AC to DC power converter can be configured to convert the AC power at the second voltage to a DC power. The energy storage system can further include an energy storage device coupled to the bi-directional AC to DC power converter. The energy storage system can be configured to receive power generated by a rotor of the DFIG via an AC line bus. The energy storage device can be configured to store the power received by the energy storage system.
