Abstract:

Most studies use the Weibull 2-parameter distribution to determine energy potential in some sites in the Niger Delta region of Nigeria. However, it is well known that parameter estimates have significant effect on the success of Weibull distribution to wind energy application. The accuracy of result obtained is based on the suitability of the method of determining the Weibull constant. Considering the need for the most accurate estimation, sixteen years (2001 to 2016) wind speed data obtained from Nigerian Meteorological Agency (NIMET) were fitted to two parameters Weibull distribution functions for selected location in the Niger Delta region of Nigeria. The data was statistically analyzed using MLM, MOM and PDM methods. The three methods applied here were further compared among themselves according to various goodness of fit criteria which include RMSE, KS, PDE, and R2 and subsequently subjected to a multi-criteria decision analysis based on the technique for order of preference by similarity to ideal solution (TOPSIS) to decide the best alternative. From the TOPSIS investigation, the PDM method proved to be the best option for estimating the parameters of the Weibull distribution at 0.962, 0.967, and 1.00 respectively for Calabar, Port Harcourt, and Yenegoa.
