In this paper, a Wind Energy Conversion System (WECS) coupled with a Three-Level Boost Converter (TLBC) using a Grey Wolf Optimization (GWO)-based Maximum Power Point Tracking (MPPT) approach is studied. The proposed WECS is designed for HVDC transmission line applications and is connected to the grid. It consists of two power converters: a TLBC and an unregulated rectifier. The TLBC is employed to increase the voltage gain, while an unregulated rectifier, powered by a Permanent Magnet Synchronous Generator (PMSG), is used for AC-to-DC conversion. Furthermore, a metaheuristic optimization method, namely the GWO-based MPPT approach, is applied to determine the optimal power point for the TLBC powered by the PMSG-based WECS. The system’s performance is evaluated under both fixed and variable wind speed profiles, specifically at 8 m/s, 10 m/s, and 12 m/s. The wind-powered TLBC with the GWO-based MPPT approach is modeled, simulated, and tested in MATLAB®/Simulink®. In addition, the proposed wind-powered TLBC with the GWO-based MPPT approach is compared with the traditional Perturb & Observe (P&O) method. The performance of the TLBC is assessed in terms of voltage gain, output ripple, settling time, and accuracy of the PMSG-based WECS. The proposed system demonstrates superior performance, achieving a high voltage gain with a boost factor of 5.996, minimal oscillations, improved settling time, and high accuracy of 99%, compared with the P&O-based MPPT approach.
