A Study of Weibull Distribution to Analyze the Wind Speed at Jogimatti in India

Wind is an available resource in nature that could be utilized by mechanically converting wind power into electricity using wind turbines. Wind energy is an indirect form of solar energy. Various probability distribution models were used for the statistical analysis of recorded wind speeds. This paper investigates the probability distributions of wind speed based on  wind speed data recorded at JOGIMATTI station in INDIA. The   Weibull distribution and  Weibull-Weibull probability  distribution  function, Mixture  Gamma and Weibull distribution, Mixture Normal and Weibull distribution  and Maximum Endrophy distribution  are adopted in this study to fit the wind speed data. It is found from the hypothesis test that  Weibull distribution is more appropriate than the other distribution. This best fit probability distribution can be used to calculate the power density.A case study is given to discuss the probability analysis results.
