Abstract
Wind Energy Conversion Systems (WECS) are gaining momentum as clean and renewable energy sources. However, variability in wind speed and associated fluctuations in power quality pose challenges in grid integration. This paper proposes an optimized control strategy for WECS using a Class Topper Optimization (CTO)-based Proportional-Integral (PI) control technique to enhance power quality, stability, and grid compatibility. The system uses a Doubly Fed Induction Generator (DFIG) to convert mechanical energy into electrical power, followed by a power conversion interface comprising a PWM rectifier, a DC link, and a Voltage Source Inverter (VSI). The CTO algorithm tunes the PI controller parameters dynamically, ensuring better system response and stability. MATLAB/Simulink is used for simulation and validation, demonstrating improved performance in power regulation and reduced Total Harmonic Distortion (THD). The proposed system ensures robust operation under varying wind conditions, ensuring efficient grid integrations.
