Wind speed modeling using Weibull distribution: A case of Liptovský Mikuláš, Slovakia

Abstract

In the present paper, the Weibull distribution is used to analyse the wind speed data of Liptovský Mikuláš-Ondrašová (49°05′52″ N, 19°35′32″ E), situated in northern Slovakia. Analysed wind speed data were collected over the 11-year period (2005-2015) and they were recorded three times a day. The results show that the seasonal values of the shape parameter k range from 1.474 to 1.607, with yearly value of 1.546 while the seasonal values of the scale parameter c range from 2.488 to 3.010 m/s, with yearly value of 2.726 m/s. We find out that according to the coefficient of determination and root mean square error, the Weibull distribution performs well in fitting the wind speed data.

Wind Energy Assessment Using Weibull Distribution with Different Numerical Estimation Methods: A Case Study

“…Sedliačková et al [10] have used MLM, which has shown good performance according to root mean square and coefficient of determination values. Another method known as the standard deviation method (SDM) or empirical method of Justus (EMJ) has been used to determine Weibull parameters in Kaplan [11], and it has yielded very good results for estimating the Weibull parameters.…”
