Approche multicritère pour la recherche de site et l'optimisation de technologies d'énergies marines renouvelables

Abstract : The research developed in this thesis introduces a methodological approach whose objective is to facilitate the search of a favorable site for the installation of a marine energy converter park in the maritime domain. In order to efficiently install a marine energy farm in a suitable region, two main objectives are considered. The first one is to identify the best location for a given technology, and the second one aims is to find the optimal farm configuration and the most adequate technologies for a given region.The introduced methodology is based on a combination of Geographic Information Systems (GIS), multi-criteria analysis (MCA) and an optimization algorithm. Three main criteria are considered in the approach: the global cost of the project, quantity of energy produced and social acceptance. The social acceptance criterion is evaluated by the MCA. The MCA retained is Electre III. The research develops a combination of Electre and GIS analysis that takes into account the conflicting nature of the different spatial constraints. The geographical dimension is taken into account thanks to a grid-oriented structural representation in which each elementary region is ranked according to the potentialities and the conflicts that may arise. The approach is complemented by the application of a genetic algorithm whose objective is to select the technical options for each spatial subdivision in order to optimize the criteria of cost and produced energy by the converters. The last step of the methodology applies Electre again to provide a decision-aid support. The whole approach generates a potential classification of the different sub-regions of the maritime space considered, according to the different technologies considered, and this by summarizing the three main criteria. Overall the method provides a decision-aid system based on the flexibility offered by the Electre parameters that can be used by both engineers and decisionmakers when studying the potentiality offered by the development of marine energy converters.
