Determination of Weibull Parameters by Different Numerical Methods and Analysis of Wind Power Density in Osmaniye, Turkey

In this study the potential of wind energy in Osmaniye Region has been analysed statistically in the basis of information that has been measured hourly between the years of 2009-2013. The two parameter Weibull Distribution Function is generally applied to evaluate potential of wind energy at any region. This study introduced the evaluation of Weibull Distribution Function parameters which are obtained by different kinds of numerical methods, namely Graphical Method (GM), Moment Method (MM), Energy Pattern Method (EPM), Energy Trend Method (ETM) and Maximum Likelihood Method (MLM). The Relative Percentage Error (RPE) statistical test is used to compare the efficiency of all used methods. The calculated power density of all used numerical methods is a major key issue for suitability use of wind energy. The evaluation of Weibull parameters and wind power distribution play a crucial role in producing electricity from wind power. The results of the used methods are compared and the obtained pre-research results show that the wind energy potential in Osmaniye Region is statistically suitable for electricity production.
