This dissertation presents a research project that consists of the development of a device that is able to supply an isolated house with electricity and to make it autonomous by using renewable energy sources. The multi-source system considered in this thesis includes a wind turbine and photovoltaic panels as main sources, Lithium-Ion batteries for storage and Diesel generator as emergency source. In order to make a contribution considering problems of energy management for hybrid systems as well as problems in controlling energy conversion chains, we are suggesting a power flow management strategy which is based on the prediction of the potential energy available on the veryshort-term. That strategy aims at generating optimal references in...
