The purpose of this paper is to determine for the site of Lome, the best model that fits the frequency histogram of wind speeds to estimate with precision the amounts of recoverable wind energy. Our study was to characterize the wind potential of Lome using the approach of Hybrid Weibull distribution because of calm winds observed in the series of wind measurements of the site. To do this, two other traditional approaches often used to model the winds have been applied to this same site to better assess the results of applying the method of Hybrid Weibull. To this end, we first determined the statistical characteristics of measurements on the site and the methods used to model wind and evaluate the wind potential. We then proceeded to apply these methods to the site data, and finally an analysis of the results to confirm the validity of using the approach of hybrid Weibull distribution was made.
