Estimation of power generation capacities of a wind farms installed in windy sites in Algerian high plateaus

The data of the wind data (speed and direction) measured over one period 10 consecutive years, of four sites located in the Algerian high plateaus, were used to determine the regional atlases of wind speed and the power densities of the areas. The results allowed the estimate of the optimal production of wind farm composed by four wind turbine adding up a rated capacity of 8 MW. The Weibull parameters, the mean wind speed and the power density according to different values of heights and roughness factors were calculated for the considered sites. The effects on the annual electrical output production in function of the RIX factor that determines the best site of the wind farm in the area and the wake effects were analyzed. The results show that the two regions, Tiaret and M'Sila are more profitable and are adapted for wind farms installation comparing with the others.
