Variation and Assessment of Wind Energy Potential at Abeokuta, Nigeria Based on Weibull Distribution
In this study , a statistical analysis of wind speed was carried out at Abeokuta station in Nigeria, by finding the
coefficient of variations and using Weibull distribution for a 10 year wind data .The data was analyzed and the results
showed that the Coefficient of Variation(CV) for a 10 year wind speed data range from 18.35% to 51.95% .These values
exceeded the variability threshold of 10% indicating that they exhibit significant variability. The shape factor and scale
factor, which are the parameters of the Weibull distribution ,the mean wind speed, probability density function and their
cumulative distribution were determined for all the years .The results of the analysis indicated that the city exhibits a low
wind since the probability density function falls between 22.0 w/m2 and 160.9w/m2 of wind power class one and wind
power class three respectively .The energy could be efficiently utilized to generate electricity if the turbine is erected and
installed properly. The wind speeds regimes for a 10 year wind data analyzed showed power density ranging between 22.0
w/m2 and 160.9w/m2. Ultimately, the results of this study shows that Abeokuta is a low wind region. However, the low wind
values that characterize Abeokuta could be effectively utilized as long as the turbines’ heights are in between 50 meters and
1500 meters respectively.
