An advanced hybrid renewable energy system combining photovoltaic (PV) solar power and a doubly-fed induction generator (DFIG)-based wind energy conversion system is designed and simulated. The system integrates a back-to-back converter with a single-stage grid-connected inverter, combining their advantages to optimize performance. The grid-side converter (GSC) utilizes a maximum power point tracker (MPPT) algorithm based on the incremental conductance (INC) method for the photovoltaic system, while the rotor side converter (RSC) applies an indirect speed maximum power point tracker control for the wind energy conversion system, enabling efficient power extraction from both energy sources. The system employs a synchronous reference frame (SRF) control strategy to ensure high-quality power delivery to the grid, maintaining stability and minimizing harmonic distortion. Simulations carried out in MATLAB/Simulink under varying environmental conditions demonstrate the system’s resilience and efficiency in providing reliable power while achieving minimal total harmonic distortion (THD). The analysis highlights the system’s performance under different wind speeds and solar irradiance, as well as its ability to maintain grid synchronization and stabilize power output during transient conditions.
