- © 2019 John Wiley & Sons, Ltd.In this paper, a solution to mitigate the voltage harmonic distortion in the stator of a wind energy conversion system based on a doubly fed induction generator is proposed. The new proposal involves the use of a three-port back-to-back converter; this topology consists of a rotor side converter, a parallel grid side converter, and a series grid side converter. The voltage harmonics mitigation is accomplished through the series grid side converter by using the theory of the instantaneous power, which has been widely used in shunt active filters. In this approach, the considered voltage harmonics from the grid are 5th, 7th, 11th, and 13th. The analytical description of the control for each converter is presented along with simulations in PSIM in order to evaluate the performance of the proposal.
