Contribution to the Protection of PVG Connected to Three Phase Electrical Network Supply

In this paper we propose to investigate, model, optimize and simulate the connection of a 3Kwc domestic photovoltaic generator to the three-phase power network throughout a current-controlled voltage source inverter. The current-controlled voltage source inverter tasks are:
• Tracking the PVG maximum power point.
• Injecting the maximum power into a three phase electrical network with unit power factor.The totality of the produced energy by the PVG has to be injected in the network, whereas the electricity requirement for domestic use has to be withdrawn from the network supply .This is in order to avoid batteries storage problems .As well as the realization of a decoupling system which can protect the generator from perturbations that can reach the electrical network supply.
