The developing countries still specifically face the challenge of access to electric power. Nowadays, the world market is therefore substantial because it concerns almost one third of our planet. In most rural areas of sub-Saharan Africa and Madagascar, less than 6% of the population has access to electricity. The standard of living of the population as well as the scattering of villages is a dilemma that does not allow the implementation of large power electric plants. Also, the load profile as well as the operating modes varies from one zone to another, according to the multi-criterion characteristics of the villages. This requires adequate and specific solutions on the energy management, the socio-economic but especially technical level.
