Doubly Fed Induction Generators (DFIGs) have emerged as a prominent choice in modern wind energy systems due to their efficiency and flexibility. To address the challenges posed by varying wind conditions and grid integration, this article presents an in-depth exploration of Sliding-Mode Control (SMC) techniques applied to DFIG-based wind systems. This paper begins by elucidating the mathematical modeling of all the elements in the conversion chain of a wind power system, followed by theoretical underpinnings of the SMC and how it can be exploited to improve DFIG performance, then it subsequently delves into the study that shows how the SMC optimally regulates rotor-side and grid-side converters in DFIGs, enabling precise active and reactive power control, seamless grid integration and robust performance under dynamic wind conditions. Finally, it presents a MATLAB/Simulink simulation to demonstrate the practical application and benefits of SMC in DFIG-based wind energy systems. The results obtained illustrate its effectiveness in maximizing energy capture.
