Résumé
Developing countries show a growing need for electricity, this need is usually answered by im porting fossil fuels from foreign countries since most of developing countries do not have their own oil or gas elds to rely on. These expenses are often unbearable for countries with very low GDP since this tight dependence on foreign countries contributes to slow social and economic development. The only way to pursue a social development that can last long is to invest in renewable energy sources. By using local, free and unlimited sources of energy like wind, sun and water is possible to decrease the long-term unbearable outlays tied to the purchase of fossil fuels. However renewable energy sources are characterised by a strong variability that collides with the need for constant power typical of many applications. Accordingly, beside any renewable energy power plant an e cient storage system is necessary to cope with the variability of these sources. Traditional storage system, based on electrochemical batteries, is still the most used in Africa where basically no other storage system has been exploited so far. This thesis proposes an alternative storage system, completely based on renewable sources (hydro+PV), in which energy is stored in terms of gravitational energy. The main advantage of this hydro+PV system is to allow not only energy production, but also storage, by using local resources. The goal of this thesis is to understand, through the feasibility study carried out for the village of Yaho (Burkina Faso), if this alternative system is competitive with the traditional one from an economic and technical point of view.
