Abstract

Solar energy has become one of the most promising renewable sources to meet growing power demands while reducing environmental impact. This paper presents the complete design and simulation of a large-scale 300 MW grid-tied solar photovoltaic (PV) system. The system uses a three- phase four-leg inverter, which offers better performance under unbalanced conditions compared to traditional three-leg inverters.


The PV array is modeled considering variations in solar irradiance and temperature. A DC-DC boost converter with Perturb and Observe (P&O) maximum power point tracking (MPPT) extracts maximum power from the panels. The four-leg inverter converts DC power to AC and synchronizes it with the utility grid using a phase-locked loop (PLL). The entire model is developed and tested in MATLAB/Simulink environment.
