Contribution à la mise en œuvre d'une méthodologie de conception d'un micro-réseau multi-sources multi-villages : cas de la région du Sahel

Abstract : Environmental issues (environmental conservation and the fight against pollution), economic (energy demand increasingly high for socio-economic development) and political (democratic access to energy) current global impose a change in energy consumption-related behavior in order not to compromise the quality of life of future generations. To this end, the use of renewable energies, including solar PV, is as one of the most promising solutions. However, because of their intermittent, it may be necessary to use in energy storage devices. These are generally used in the case of isolated sites of the electricity grid but more and more research work focuses on the integration of storage units in photovoltaic systems connected to electricity networks ( "smart"). The implementation of the storage means and to optimize production and improve the profitability of electricity while enabling smooth network calls in peak powers.For hard to reach areas, the electricity storage ensures energy independence by adjusting production to consumer needs and vice versa. This causes a continuous process of charging and discharging of the storage units that can profoundly change the physicochemical properties and electrical storage systems with consequent reduction in operating life of the installation. Generally, the technical characteristics of storage units are determined by manufacturers under ideal operating conditions, including current and constant temperature. Also, when the operation takes place in austere weather conditions, such as those of the Sahel, the real life of these systems can be very different predictions based on the manufacturer. These countries, large solar fields, are characterized by arid soils and large stretches of desert very hot and the people he makes are scattered in small hamlets, making stand-alone photovoltaic systems the best candidates to meet energy needs. For proper design and effective implementation, it is important to know the behavior of the system components in the climatic conditions of the target sites. It must indeed know the impact of these on the life and characteristics of components, to determine the possible need for conditioning devices and consider the scientific and technical studies of their implementation. The proposed research aim to answer these many questions based on an experimental platform and models, and produce terms of IT tools for decision support
