A doubly fed induction generator wind turbine (DFIG-WT) under unbalanced load condition is presented. It is demonstrated that the grid-side converter can supports the grid under unbalanced load conditions as well as provide power factor correction without disturbing the DFIG-WT. The controller is based on symmetrical components and a vector control scheme. With the grid-side converter, power compensation support can be done at a specific point away from the wind turbine plant. The system is fully operational at zero output power from the DFIG-WT and independent of the rotor-side control strategy. Simulation results illustrate good performance of the proposed system
