Modélisation énergétique et optimisation économique d'un système de production éolien et photovoltaïque couplé au réseau et associé à un accumulateur

This thesis deals of the production of photovoltaic and wind electricity connected to the grid and having a storage. The principal interests of such a system are the clean production on the place of consumption, the mutualisation of the resources, and the security of supply. In a first part, models are developed and compared successfully with reality thanks to an experimental device instrumented completion. We obtain then a model that proves both accurate enough to distinguish energy transfers and fast enough to enable optimizing the sizing and handling of the system's energy transfers. Having energy, economic models and tools of dimensioning and management, we carried out a study of optimization based on simple cases of systems multi-production. To tackle this difficult problem, we then placed ourselves within the framework of a producer-consumer whose conditions weather with the site of production as its own consumption are supposed to be known, therefore deterministic. The problems were then the search for strategies of management of flows of energy and the fundamental characteristics of the elements of the installation optimal allowing the minimization of the energy cost.
