Hybrid system of the existing central diesel with photovoltaics, technical and economic feasibility, case of Talmine

摘要

The supply of electricity to the rural villages in the south of Algeria where the dispersion of population is very important and the increase in the rate of consumption of electrical energy constitute two major problems encountered by the company of electricity in Algeria. Electricity generation in large southern Algeria is based primarily on diesel power production with enormous technical, economic and environmental impacts. The alternative would be ideal with the use of hybrid photovoltaic system. Consequently, we considered the feasibility study of the hybrid system with diesel power and photovoltaic's the best solution and reliable option. Indeed, we studied the actual application of the hybridization of an existing diesel central situated in the south of Algeria in locality of Talmine. Power station and electrical data, weather forecast of southern are used in our hybrid system. Moreover the software HOMER is used in this study to evaluate the feasibility of various hybrid systems essentially with frequent rises in fuel prices in this region of the Sahara. The term hybrid energy system is frequently used to illustrate a power system with more than one type of generator, usually a conventional generator powered by a diesel or gas engine and a renewable energy source such as a photovoltaic (PV). The optimization modeling proves that 100% of power demand can be supplied by hybrid configuration composed of system PV and generator diesel. The cost of generating energy from our system has been found 0.648 S/kWh.
