Harmonics Rejection in Stand-Alone Doubly-Fed Induction Generators With Nonlinear Loads

This letter proposes a novel method to reject 6n ± 1 harmonics in the stator voltage at the point of common coupling (PCC) for a stand-alone doubly-fed induction generator (DFIG) supplying a balanced three-phase diode rectifier. These harmonics are rejected by using the rotor current controller in the fundamental synchronous reference frame. The proposed control algorithm is based on a proportiona...
