| Summary: | Main objectives of the study are to progress a dual independent doubly fed induction generator (DFIG)-based wind energy conversion system (WECS) for stable and efficient power delivery to an AC microgrid while ensuring grid stability and compliance with power quality standards. In order to achieve the set goals, the following tasks were accomplished: integration of a Pulse Width Modulation (PWM) rectifier for AC to DC conversion, implementation of a SEPIC converter for voltage boosting, tuning of proportional integral (PI) controller parameters using whale optimization algorithm (WOA) for dynamic DC voltage regulation, and design of a 3Φ Voltage Source Inverter (VSI) for efficient management of active and reactive power to the grid. The scientific novelty of the proposed work is the inclusion of dual independent DFIG system with SEPIC converters and optimized PI controllers. The most important results are the demonstration of consistent DC voltage stabilization, improved power quality under varying wind conditions, and an overall system efficiency of 97%, verified through MATLAB simulations. These attained outcomes are found to be more efficient when compared to other existing converters and optimized controllers thereby satisfying the objectives of meeting desired voltage demands of grid and achieving highly stabilized output power. The significance of obtained results is the establishment of an advanced DFIG-WECS-based wind energy system capable of enhancing grid performance, ensuring reliable integration of renewable energy, and maintaining power quality and stability in compliance with modern grid standards. |
