Doubly fed induction generator wind turbine control for a maximum power extraction

Wind turbine WT occupies gradually a large part in world energy market, Doubly fed induction generator DFIG is mostly used in WT, it allow highly flexible active and reactive power generation control. These machines are driven by power collaborating converters: voltage source converter VSC and rotor-side converter RSC protected using crowbar protection against transient over current. This paper develops a DFIG dynamic model, driven by wind turbine model using PSCAD/EMTDC a powerful tool allowing power system analysis to investigate simulations. A control strategy is also established using PI regulator to control stator-grid power flow according to maximum power point tracking MPPT strategy.
