Abstract: The grid-integrated dual wind turbine system using a whale-optimized PI controller with a SEPIC converter aims to efficiently convert variable wind energy into stable grid-compatible power. Existing systems face challenges such as inefficient energy conversion, poor grid stability, and complex control strategies. The proposed approach addresses these issues by integrating advanced control techniques and optimizing power conversion with improved voltage regulation. This project proposes a wind energy conversion system (WECS) that utilizes doubly fed induction generators (DFIG) integrated with a dual DC wind turbine (DCWT) configuration. The system employs a pulse width modulation (PWM) rectifier and a DC-DC SEPIC converter to effectively manage the conversion of variable wind energy into stable DC voltage. Each DCWT is equipped with a whale-optimized proportional-integral (PI) controller to regulate the DC voltage, ensuring efficient energy transfer to a common DC bus. The architecture also features a three-phase voltage source inverter (VSI) connected to the AC grid, enhanced with an LC filter for improved power quality. The PI controller on the AC side enables precise control of active and reactive power flow into the grid, thereby maximizing energy utilization and grid stability. This integrated approach aims to enhance the performance and reliability of renewable energy systems, contributing to sustainable energy solutions while addressing the challenges of grid integration. This project is implemented by Matlab simulation 2021a.
