Ecological Analysis of a Wind-Diesel Hybrid Power System in the South Algeria

The electrical energy is often produced with the help of diesel generators in isolated areas in the Saharan region. These generators require relatively a little investment, because it is generally expensive to exploit them due to the transportation (transportation to remote areas adds extra cost, significant fuel consumption and relatively high maintenance costs). Moreover, the electricity production by the diesel generators is ineffective and presents significant environmental risks. But these isolated areas have significant wind energy potential, which is good position for the exploitation of clean and sustainable wind energy. The use of wind-diesel power system is widely recommended especially to reduce fuel consumption and in this way to reduce system operating costs and environmental impact. The subject of this paper is to present the simulation of a wind-diesel power system. This system has a high-control strategy for the management of different power sources (wind, diesel, battery) that depends on weather conditions, especially wind speed values and the power demanded by the consumer load.
