Stochastic Distribution Controller for Wind Turbines with Doubly Fed Induction Generator

The major purpose of this work is to design the controllers for controlling variable speed, pitch wind turbine (WT) with doubly fed induction generator (DFIG). Vector control strategy adopted DFIG active and reactive power. Generator torque provide regulated real power minimum fluctuation. fixed gain proportional-integral (PI) controller designed converter rotor side grid has limited operating range inherent overshoot. Gain scheduling PI minimize overshoot fluctuation exists in controller. Since based energy conversion system (WECS) works uncertain stochastic distribution (SDC) method proposed probability function (PDF) WECS. It copes nonlinearities WECS contiguous variations at point provides satisfactory performance whole region. improves together quality generated electric thereby maximizing lifespan installation ensures secure acceptable operation
