Analysis of Wind Speed Data for Four Locations in Ireland Based on Weibull Distribution’s Linear Regression Model

Abstract

Wind speed is the most important parameter in the design and study of wind energy conversion systems (WECS). The main aim of this study is to assess wind power potential of a site for wind power plant development. Availability of wind energy and its characteristics at Malin Head, Dublin Airport, Belmullet and Mullingar in Ireland has been studied based on primary data collected at these sites for a period of seven years. The wind speeds at height of 50 m above ground level were measured. Two parameter Weibull distribution’s linear regression model is used for analyzing wind speed pattern variations. Weibull parameters are calculated by using Least Squares Fit Method (LSM). Our analysis shows that the coastal sites of Ireland such as Malin Head, Dublin Airport and Belmullet have good wind power potentials. These potentials if utilized they will provide solution towards power shortage problem of Ireland. Large magnitudes of winds for power generation occurred during the months of October to March and in May month.
