Evaluation of the wind energy potential in the Saharan sites of Algeria

Our study present a study of the wind layer in seven Algerian sites "Saharan sites" (In Amenas, In Salah, Tindouf, Adrar, Béchar, Ghardaïa and Tamanrasset). This study is based on data and statistics published in the atlas wind of Algeria established by the National office of the Meteorology, which had 37 stations of measures. The annual average wind speed for the selected sites ranged from 4.00 m/s to 7.20 m/s and a mean wind power density from 82.51 W/m² to 283.12 W/m² at standard height of 10m. The wind speed and the Weibull parameters were extrapolated standard height 10m with 30 and 50m by using vertical extrapolation laws. The Weibull parameters k and c are determined and used for estimate the annual average wind speed and the power density for each site.
