Résumé
This thesis has been conducted to couple hourly wind data of six different measurement station in Tunisia provided from Tunisian meteorological stations to the electricity consumption in a timeline fashion. The idea is to evaluate the wind potential for a few locations around Tunisia using Weibull distribution and Meteorological methods. The latent of wind power was statistically investigated including the average wind velocity and wind direction frequency data for 25 years (1990-2015) in 25 places in Tunisia. Using the two methodologies, 6 stations have been selected and considered as the most potent locations in term of wind energy, where the hourly average velocity is more than 4m/s and wind direction frequency exceeds 15%. The data was analyzed using MATLAB software in order to find out the generation of wind power. Weibull distribution was followed to calculate speed distribution in all the six areas chosen. A 3.2 MW wind turbine as been selected according to the findings of the hourly wind power potential. Results shows that Thala is the best area in Tunisia in term of wind energy. During September the energy production using 3.2 MW wind turbine exceeds 12 GWh in Thala. The last part of this project, is to compare hourly energy production and hourly energy consumption during January, March, July and September. The purpose of this comparison is to study the overproduction of power produced by the selected wind turbine and see if complementary storage energy devices are needed.
