There are two types of DC-DC buck-boost converters used in solar Maximum Power Point Tracking (MPPT) PV systems: stand-alone and grid-connected. Stand-alone PV systems are employed in places where there is no access to the utility grid. The performance of a PV system in these systems is determined by the operating conditions. Three variables have a significant impact on the maximum power collected from a PV source: irradiation, load profile, and temperature. Grid-connected PV systems are employed in places where the utility grid is readily available. The solar module provides the maximum power at the point on the I-V curve where the product of voltage and current is greatest. The Maximum Power Point is the name given to this point (MPP). The voltage level at each bus, as well as transmission line losses, have been simulated and tabulated. The consequences of integrating wind turbine generators with the defined grid have been studied. This thesis proposes a DC-DC Buck-Boost converter with a solar MPPT algorithm for the analysis of solar PV installations. When compared to the other converters stated in this study, the proposed technique outperforms them.
