This paper proposes a new control strategy to the grid side converter (GSC) of a DFIG-based wind turbine enabling the DFIG’s FACTS features. This control strategy is based on the pq Theory which take advantage of this converter to improve the energy quality at the point of common coupling (PCC) acting as an active filter in the specific case adopted in this article. The control strategy of the rotor side converter (RSC) adopted was the classical field-oriented control which determines the active and reactive power that will be injected in the electrical system. Simulation results in PSCAD/EMTDC and some discussions are also shown throughout the paper.
