Contribution à l’étude d’un système photovoltaïque autonome

Abstract

This thesis deals with the optimization of a stand-alone photovoltaic system. Firstly, energetic and economic models are developed. We obtain a model that proves both accurate and fast to enable a good optimization. Next, the action on the load profile which allows us to get a closer perspective of the ideal solar behaviour of the consumer has been studied. The life cycle primary energetic cost of the photovoltaic system has been put forward by the downsizing of the lead-acid battery. Finally, we carried out a study of optimization based of Algeria sites applications. Two economics models are considered. The problem were then the search of the fundamental characteristics of the elements of the installation optimal allowing the minimization of the economic cost.
