Analysis of the modified weibull distribution for estimation of wind speed distribution

Abstract

Finding suitable wind speed distribution is one of the most important tasks for the correct estimation of wind energy potential of the specified region. The Weibull distribution is the well-known and suggested distribution in estimating wind energy potential. However, in order to predict wind energy more correctly, new and flexible statistical distributions have been proposed in the last decade. In this study, we introduce a new modified Weibull distribution (MWD) for modelling wind speed and estimating wind power density and also we test MWD versus the classical Weibull distribution on real wind speed data measured in various regions of Turkey. The results of the analysis indicate that MWD suits well for most of the examined wind data cases. Therefore, MWD can be alternatively used for assessment of wind energy potential. Copyright 2015 ACM.
