MATLAB Code Implementation for Photovoltaic Inverter Simulation

In power systems, photovoltaic (PV) power stations represent one of the critical renewable energy sources. The PV inverter serves as a fundamental component within these stations, converting direct current (DC) generated by PV arrays into alternating current (AC) for grid integration. During this process, PV inverter simulation technology plays a vital role by enabling control over voltage/current characteristics and harmonic distortion during grid synchronization. This ensures operational efficiency and stability of PV power plants. Key simulation aspects typically involve implementing maximum power point tracking (MPPT) algorithms, PWM modulation techniques, and harmonic analysis functions in MATLAB. Common approaches include using Simulink's Power Systems toolbox to model inverter topologies, implementing Clarke/Park transformations for three-phase control systems, and applying FFT analysis for harmonic quantification. The research and development of PV inverter simulation technology significantly contributes to advancing the implementation and optimization of photovoltaic power generation systems.
