DFIG using its FACTS Features through the Grid Side Converter in Grid-Connected Wind Power Application

Abstract

This paper proposes a new control strategy to the grid   side   converter   (GSC) of   a   DFIG-based   wind   turbineenabling  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/EMTDCand some discussions are also shown throughout the paper.
