Toward Robust Wind Turbine Control: From Disturbance Management Using LADRC to AI-Based Fault Prediction (GEO-ANN)
Abstract
The large-scale integration of wind energy using Doubly Fed Induction Generators (DFIGs) poses significant challenges to grid stability. Due to the inherent intermittency of wind and the sensitivity of power converters to disturbances, maintaining a stable and high-quality power output remains a critical issue. This paper presents a comprehensive review of advanced control strategies for DFIG-based wind energy systems, with particular emphasis on Linear Active Disturbance Rejection Control (LADRC) combined with Bi-LSTM neural networks, the nonlinear Integral Backstepping (IBSC) controller, and the GEO-ANN method. These approaches, as reported in the literature, demonstrate significant improvements in mitigating power oscillations, enhancing power quality, and increasing system robustness under grid disturbances such as voltage dips. The reviewed results highlight the effectiveness of these techniques in reducing total harmonic distortion (THD) and improving fault detection capabilities. Overall, this study underscores the growing role of intelligent and hybrid control methods in stabilizing modern power systems and outlines future research directions toward large-scale industrial implementation.
