The objective of this work is to study the performances of a photovoltaic (PV) system connected to the grid using a Voltage Source Inverter (VSI).
To obtain the maximum power from a photovoltaic generator and to match the solar cell power to the environmental changes a DC-DC buck-boost inverter controlled by the fuzzy logic command is used.
The effectiveness of grid-connected photovoltaic power generation systems depends on the efficiency of the DC-into-AC conversion. For the grid connected inverter is desirable to provide the unity power factor. The performance of grid connected photovoltaic system using a two level inverter which can synchronise a sinusoidal current output with a voltage grid is shown by the numerical simulation.
