FFT analysis-based P&O with IC for 100 kW two stage grid-connected PV system: Comparative study

Due to dynamic interactions between PV systems and the grid, the development of large-scale solar systems distributed via a low-voltage distribution grid (LVDG) presents substantial problems to network operators. In order to address these problems and provide grid support services (GSS). To allow for the simulation of large-scale, interconnected PV systems in a reasonable amount of time, precise and effective PV system models are required. This article provided a method of control for adjusting the CC's tension as well as the CC's rate of change in energy. A two-stage conversion system is employed. A comparison of control strategies for photovoltaic systems connected to the grid is proposed. The Boost DC-DC converters in charge of connecting and extracting the maximum power from the solar panel and transferring it to the DC connection are controlled using the maximum power point extraction method with perturb and observe and incremental inductance. Finally, the frequency analysis of the energy transmitted is visualized. The model and simulation system were created using MATLAB/Simulink.
