A HYBRID SYSTEM (WIND, SOLAR) FOR THE ELECTRIC SUPPLY OF A LOAD AS A DOMESTIC USE

摘要

The exploitation of the energetic potential (solar and wind) for the production of electricity proves to be anadequate solution in isolated regions where the extension of the grid network would be a financialconstraint. So the proposed work consists in the sizing of a hybrid system (solar and wind) with continuousproduction of electrical energy. This being based on meteorological and radiometric data measured onsite, this survey allowed us to put into evidence that the management of this system depends essentially, onthe one hand on the available renewable energies and on the other hand on the needed consumption. Thisdrove us to plan for some suitable storage systems to insure a better autonomy. Furthermore, the simulationin real time of the working of different parts of the system, allowed us to define the best energeticcontribution between the wind generator and the photovoltaic generator. A more deepened technic0 -economical survey on this hybrid system, will allow us to put better in evidence that when the twopossibilities are technically possible, the choice between these solutions must be used in order to determinethe optionthat correspondsto the least cost.
