Technical and economic sizing of the energy storage in an autonomous hybrid power generator for rural electrification in sub-equatorial area of Africa

Résumé

This paper analyzes and evaluates the possible technical and economical optimization of electricity production by autonomous hybrid power generator from renewable sources integrating an electrochemical storage system. A progressive combination of wind-turbines to photovoltaic modules is carried out in order to minimize the size of the electrochemical storage system over the cost of the resulting autonomous generator. An autonomous system with solar PV is dimensioned with respect to the needs in electricity of a given electrical installation. Beyond the original methodology presented in this paper, the case of the Maroua-Kongola High School site is investigated as applicative example. Considering the " weight " of storage in the overall financial costs of such an autonomous system, the generator is hybridized by attaching wind-turbines to it, adding a possibility of energy production during night and, consequently making the system technically more reliable with a less need of storage capacity and finally, a global production system economically cheaper. By the so called " down approach " dimensioning method, the optimum combination (f, (1-f)) of photovoltaic and wind power contributions in the hybrid system PV-wind power generator is thus determined by adjusting the storage capacity to the source capacities and the operating requirements of the investigated site.
