Abstract

In this work, three methods are proposed to identify parameters of PI controllers used for wind energy conversion systems based on DFIG. Mathematical model of generator and grid side system is depicted. Three tuning methods; bode-plot, pole-placement, and MATLAB tuner are used for grid side and rotor side converter controllers’ design. Wind turbine system with PI controller parameters obtained using the mentioned method is investigated via MATLAB/SIMULINK under three different scenarios. The wind system is subjected to step wind speed change, random wind speed, and sever symmetrical voltage dip in the grid. The handled comparison illustrates that the pole-placement tuning method is easy to implement. Also, the PI parameters obtained using this method give less DC bus voltage overshoot and settling time. It also gives reduced ripples in rotor and grid currents and minimized torque ripples in comparison to the PI parameters obtained by the two other methods.
