Research on Maximum Power Point Tracking Technology for a Photovoltaic Grid-connected Power Generation System

This paper establishes an equivalent circuit of photovoltaic cells, plots the output characteristics under different temperatures and irradiance levels, and introduces common maximum power point tracking control algorithms, including the constant voltage method, perturb and observe method, and incremental conductance method. Finally, a simulation model is established in MATLAB for experimental analysis, and the results verify the superiority and feasibility of the control algorithms.
