Analysis of wind energy prospect for power generation by three weibull distribution methods

Wind energy is one of the fastest growing sectors in renewable energy. These energy resources are freely available throughout the world. It is one of the zero emission energy sources. The wind energy is used mainly for two purposes namely irrigation (water pumping) and electricity generation. The prospect of wind energy can be analyzed by different methods. Weibull distribution method is one of the widely acceptable methods for estimating wind energy. In this paper, the prospect of wind energy in Bangladesh is analyzed by Weibull distribution method. The data were collected from Meteorological Department of Bangladesh located in different areas of the country. Three different Weibull distribution methods were used to find out Weibull parameters which were verified using different widely acceptable statistical tools. Relative percentage error, chi-square error, analysis of variance etc. are the efficient statistical tools to rank the method which was used in this study. The study identified the most prospects windy site by applying efficient least square method with minimum error.
