Performance analysis and enhancement of direct power control of DFIG based wind system

<span lang="EN-US">The paper proposes a complete modeling and control technique of variable speed wind turbine system (WTS) based on the doubly fed induction generator (DFIG). Two levels back-to-back converter is used to ensure energy transfer between DFIG rotor grid. The operate efficiently, maximum power point tracking (MPPT) algorithm implemented. Then, direct (DPC) strategy has been combined with MPPT in order guarantee selection appropriate voltage vectors minimize active reactive errors. Finally, simulation performed by using MATLAB/simulink platform basing 7.5KW generation system, results prove effectiveness our proposed technique.</span>
