Résumé:
Global energy consumption is constantly increasing with the reduction of fossil energy
resources. With the opening of electric power markets and state incentives, decentralized generation based on renewable energies is developing in all countries. Among renewable sources, wind turbines and photovoltaic (PV) systems presenting great interests. Our aim is to connect the renewable solar energy generator to the low voltage grid and to check the availability of all ideal connection conditions and to add the uncertainty rate of the inverter to ensure good energy without any Attached to the return of the electrical network. First, a brief theoretical overview of solar technology was presented. Then, we studied and simulated the photovoltaic panel. We have carried out a general study on the various methods that follow the maximum power MPPT, constitutes a study on the converter (DC-DC) used in the majority of the photovoltaic systems (PV) that they are connected to the electrical network and their method (MLI, fuzzy logic). We will try to connect system with a BT network by a three-phase inverter controlled by the MLI.
