A comparison of grid-connected photovoltaic systems using P&O and Fuzzy Logic MPPT algorithms

Photovoltaic solar energy, derived from solar radiation, has become one of the most widely used renewable energy sources in recent years. In this paper, we compare two MPPT control algorithms, P&O and fuzzy logic, in a grid-connected photovoltaic solar system. A DC/DC Boost converter is used to optimize power by providing a higher continuous voltage, while an inverter converts this energy into alternating current, which is injected into the grid. The goal is to generate clean energy to supply electrical loads or inject any surplus into the grid.
