Robust Control of DFIG Wind Turbines in Sub/Super-Synchronous Operation Using Integral Backstepping Controller

Abstract

This paper presents a robust control strategy for Doubly Fed Induction Generator (DFIG) wind turbines in Sup/Super Synchronous operation using an integral backstepping controller (INT-BCS-Control) based on the Lyapunov function. The objective of this work is to decouple the active and reactive power of the DFIG with high robustness and enhance the performance and reliability of DFIG wind turbines operating in the Sup/Super Synchronous mode within grid-connected systems. The effectiveness of the control strategy is validated through simulations conducted using MATLAB Simulink.
