Contribution à l’optimisation d’un système hybride (PV/éolien) avec stockage d’énergie connecté au réseau électrique

Abstract

The work achieved in this thesis presents an optimization study of a hybrid energy system constituting a photovoltaic panel, a wind turbine and a storage energy system connected to the electrical network. A techno-economic analysis was proposed in this study with the aim to solve the optimization problem and find an optimal solution concerning the cost and the sizing of the hybrid system with a considering the voltage fluctuation. In this case, a new energy management strategy has been applied between the hybrid system and the grid, which depends on two strategy processes and are identified by the storage and buying energy. A metaheuristic method named particle swarm optimization (PSO) was used and compared to other improved and developed methods based PSO, in order to found a better solution regarding to the optimization problem. The use of the BESS in this work demonstrates its advantages as storage energy, reducing voltage perturbation and managing the energy management. The simulation results, obtained under MATLAB environment, show the effectiveness and efficiency of the FC-VACPSO method as it converges faster and gives a better benefit cost for the studied system than other methods
