A Master thesis was discussed in Department of Electrical Engineering / College of Engineering at University of Mosul entitled “Comparison of Control Methods for the Double Feed Induction Generator used in Wind Energy Systems”, submitted by (Ahmed Sami Antar Aboud), Supervised By Assist. Prof. Dr. Mohammed Obaid Mustafa and Dr. Saad Enad Mohammed Monday, March, 3, 2025.

The thesis presented by, “Ahmed Sami Antar Aboud” aimed to Model and Simulate, and Implement of a Wind Turbine System Based on the Doubly-Fed Induction Generator (DFIG) at Fixed and Variable Wind Speeds. Study of Control for the Doubly-Fed Induction Generator (DFIG) System Using Proportional-Integral (PI) Control Method and Proportional-Integral-Derivative (FPID) Control Method, and a Comparison Between Them.

The thesis discusses Study of the Effect of Wind Speed Variation on the Generation System Using the FPI Control Method, which Successfully Overcame the Disturbances Caused by Wind Speed Changes; the System Became More Efficient by Reducing Oscillations, and the Active Power, Speed, and Generator Torque Became Smoother. The Rise Time Was Reduced, and the System’s Stability Improved When Dynamic Changes in Wind Speed Occurred.

The results showed the FPI control method is better than the traditional PI control method, providing faster and more accurate response, and making the active power and current smoother. Additionally, the FPI method was able to handle fluctuations and changes in wind speed while maintaining stable behavior and performance of the generator, thanks to the selection of appropriate controller parameter values.
