Contribution à l'optimisation de l'architecture de parcs d'hydroliennes

Abstract : Renewable Energies (MREs) can contribute significantly to the energy mix. MREs can be produced from different sources, among them tidal energy – the focus of this work – has aroused major interest from industrialists and decision-makers.In this thesis, a decision support tool for the optimization of the architecture of tidal farms is developed. The optimization tool, named OPTIFARM, takes into account the hydrodynamics of the site, the investment and maintenance costs, the loss of production caused by the wake effect and the energy loss in the electrical network. The tool allows determining the optimal number and positions of tidal turbines and offshore substations in the farm as well as the optimal AC electrical connection topology of the tidal farm network. The optimization tool relies on a genetic and a particle swarm optimization algorithms. OPTIFARM is applied to two French tidal energy sites: the Alderney Race located between the Alderney Island and Cap de la Hague, and the Fromveur Strait located in the sea of Iroise. Those sites represent respectively the first and the second greatest tidal potential in France. The results show that the energy production cost considerably differs from one site to another and it strongly depends on the size of the farm.
