Comparative Analysis of Wind Speed Models Using Different Weibull Distributions

Abstract

A wide variety of distribution functions are used in the literature for wind speed modelling. It is the most widely used Weibull distribution (WD) function in wind speed modelling. In this paper, two-parameter WD, Rayleigh distribution (RD) which is a special form of WD, and Inverse Weibull distribution (IWD) offered for a new seasonal wind speed modelling are considered and analyzed for six different regions (Gokceada, Bozcaada, Bandirma, Bilecik, Yalova and Sakarya regions) in the Northwest of Turkey, comparatively. The hourly wind speed data for the period of October 2015 to 30 September 2016 is taken from Turkish State Meteorological Service. As a result of the comparison, it is seen that the WD is generally suitable, although IWD has good seasonal results in some regions. All the comparative results are given in tables.
