Wind energy is far more uncertain compared to Photovoltaic because of wider energy swell and voltage sags, to protect the conversion devices in downstream power stages the energy has to be managed in a way that controlling the torque by balancing the magnetization force in turbine. The control unit feed the coil with current from where the turbine generated , at the level of hundreds of volts. Like a buck conversion, the tunned output somehow cancels generator magnetic field when power rating is over high by generate opposite flux, and on the other hand enhance it for smoothing voltage sags.
