Modélisation d’une centrale à énergie renouvelable photovoltaïque-éolienne.

Abstract

This thesis has the objective to : study, model, control and optimize the power operated in a hybrid photovoltaic-wind system. Beginning with a theoretical part about the state of the art renewable energy photovoltaic-wind. The second section on modeling, control and optimization of the hybrid system, the speed control of the is provided by a regulator of the electromagnetic torque type and other hysteresis for the control of stator currents. The MPPT algorithm is based on the principle of perturbation and observation with variable convergence step in the case of wind system. Then comes, the phase of separate injection of energy collected in the two central network, where we discussed the values of passive elements ensuring the transfer of energy ( bus capacity and inductance coupling). In the end, we performed the hybridization phase of the two systems at the DC bus, so that the collected power is moving to the network through a single inverter instead of two separate.
