In the last 15 years, Double Fed Induction Generator (DFIG) had been widely used as a wind turbine generator, due its various advantages especially low generation cost so it becomes the most important and promising sources of renewable energy. This paper presents new control approachfor a doubly-fed induction generator (DFIG) wind energy system in an unbalanced microgrid based on fuzzy logic controller.The proposed fuzzy logic controllermodel uses instantaneous real/reactive power components as the system state variables. This work focuses on studying of using DFIG as a wind turbine connected to a micro grid subjected to unbalanced loads. Furthermore the control of real/reactive powers, the controllers uses the rotor-side converter for mitigating the torque and reactive power pulsations. The control scheme also uses the grid-side converter for partial compensation of unbalanced stator voltage. The main features of the proposed control method are its feedback variables are independent of reference frame transformations and it does not require sequential decomposition of current components.These features simplify the structure of required controllers under an unbalanced voltage condition and inherently improve the robustness of the controllers. A power limiting algorithm is also introduced to protect power converters against over rating and define the priority of real/reactive power references within the control scheme. The performance of the proposed strategy in reducing torque ripples and unbalanced stator voltage is investigated based on the time-domain simulation of a DFIG study system under unbalanced grid voltage.
