Modeling and Simulation of a PV-Based Boost Converter with Maximum Power Point Tracking
Main Article Content
Abstract
This study presents the modeling and simulation of a hybrid renewable energy system integrating solar photovoltaic (PV), wind energy, and battery storage using MATLAB/Simulink. The system is designed with a common DC bus architecture, where the PV array operates under a Maximum Power Point Tracking (MPPT) controller, and the battery is connected through a bidirectional DC–DC converter for energy management. A DC–AC inverter with PWM control converts the DC power into three-phase AC, which is supplied to the load and utility grid through an LC filter.Simulation results demonstrate that the PV system achieves a stable DC voltage of approximately 375 V, while the inverter delivers a constant output power of about 5 kW. The three-phase voltage and current waveforms are balanced and sinusoidal, indicating efficient inverter performance with good power quality. The battery effectively supports the system during fluctuations, and the overall system maintains stability under varying wind speed conditions.The results confirm that the proposed hybrid system provides reliable, efficient, and continuous power supply, making it suitable for grid-connected and standalone renewable energy applications.
