The present chapter presents a control technique to deal with the control of doubly fed induction generators under different voltage disturbances. Certain current reference values are chosen in the positive and negative sequences so that the torque and theDCvoltage are kept stable during balanced and unbalanced conditions. Both rotor-side and grid-side converters are considered, detailing the control scheme of each converter while considering the effect of the crow-bar protection. The control strategy is validated by means of simulations.
