Abstract
<jats:p>This paper presents the design, simulation, and experimental validation of a Genetic Algorithm (GA)-optimized Active Disturbance Rejection Controller (ADRC) for voltage regulation in a standalone Doubly Fed Induction Generator (DFIG)-based Wind Energy Conversion System (WECS). The proposed system is designed to operate under variable wind conditions and nonlinear load profiles, with a battery energy storage system (BESS) connected to the rotor side to enhance performance and stability. A battery management algorithm is incorporated to ensure safe operation and maintain the state of charge (SOC) within optimal limits. The control strategy is evaluated through detailed simulations in MATLAB/Simulink and validated experimentally using a real-time dSPACE 1104 platform. Results show that the GA-tuned ADRC offers superior voltage regulation, fast transient response, and strong disturbance rejection compared to conventional PI controllers. Moreover, the integration of the battery management algorithm ensures reliable energy flow and SOC control, confirming the practical feasibility of the proposed method for isolated renewable energy applications.</jats:p>
