Estimation of Weibull parameters by different methods for assessment of wind energy potential

Abstract

Wind speed distributions estimations is a challenging job for establishing wind mill or wind farms. Many statistical methods reported recently were reviewed and found that Weibull distribution is widely used wind speed modelling. In the present study, by using three different statistical methods namely, Methods of Moment, Empirical Method and Power Density Methods used for estimating two Weibull parameters (shape factor-k and scale factor-c(m/s). For identifying the goodness of fit, root mean square error, chi-square error and R2 were considered and found that all three methods were performing in the same way and no any method is superior over the other.
