The growing global demand for electrical energy, along with increasing environmental concerns and the depletion of fossil fuel resources, has accelerated the adoption of renewable energy technologies. Among various renewable sources, solar photovoltaic (PV) and wind energy systems have emerged as promising solutions due to their abundance and sustainability. However, the intermittent and uncertain nature of these energy sources limits their ability to provide reliable power when operated individually, thereby motivating the development of hybrid renewable energy systems.This paper presents the modeling, control, and simulation of a grid-connected solar PV–wind hybrid energy system designed to enhance power reliability and maximize renewable energy utilization. The proposed system integrates a solar PV array and a wind energy conversion system (WECS) through a common DC-link and interfaces with the utility grid using a grid-side inverter. Maximum Power Point Tracking (MPPT) techniques are employed to extract the maximum available power from both renewable sources. The solar PV subsystem utilizes a DC–DC converter with an MPPT control scheme, while the wind subsystem employs an optimal torque control–based MPPT strategy for efficient wind energy extraction.The complete hybrid system is modeled and simulated using the MATLAB/Simulink platform under varying solar irradiance and wind speed conditions. Simulation results demonstrate effective maximum power extraction, stable DC-link voltage regulation, and smooth power injection into the grid. The outcomes confirm that the proposed grid-connected PV–wind hybrid system provides an efficient, reliable, and sustainable solution for modern renewable power generation.
