Contribution à la commande et la gestion énergétique d'un système hybride (PV/Eolien) autonome

Abstract

The work presented in this thesis aims to contribute to the energy management between the various sources of a hybrid energy system, in order to provide electricity to a home located on an isolated site and ensure its autonomy thanks to renewable energy sources. The multi-source system envisaged integrates solar panels, a wind turbine as main sources, as well as lead-acid batteries for energy storage. First, we introduce a modeling of the various components of the multi-source energy system under MATLAB/Simulink. This step allowed us to optimally determine the size of the hybrid system. Optimization methods were considered to manage and optimize the energy of the system, in order to ensure its optimal operation while taking into account the constraints inherent to variable energy sources. Then, still in the same context of energy management, we examine the influence of the thermal insulation of the building envelope on the energy efficiency of the habitat and on the multi-source energy system. We use the "TRNSYS 18" software as a thermal simulation and evaluation tool in order to reduce the energy needs in heating/air conditioning and improve the energy performance of the building. The results obtained showed that the thermal insulation of the walls has a significant impact on the reduction of energy consumption and on the behavior of the electrical energy supply system provided by the hybrid renewable energy system.
