Wind power potential assessment for seven buoys data collection stations in Aegean Sea using Weibull distribution function

摘要

This paper utilizes three hourly measured values of wind speed and direction fromseven buoys data collection stations in Aegean Sea to study the wind speed andpower characteristics applying the Weibull shape and scale parameters.Specifically, the site dependent, annual and monthly mean patterns of mean windspeed, Weibull parameters, frequency distribution, most probable wind speed,maximum energy carrying wind speed, wind power density and wind energydensity characteristics have been studied. The Weibull distribution was found torepresent the wind speed distribution with more than 90% accuracy in most of thecases. Slightly decreasing trends were observed in annual mean wind speed valuesat Lesvos and increasing at Mykonos. The mean values of wind speed, scaleparameter, most probable wind speed, maximum energy carrying wind speed, windpower and wind energy density values showed higher values during winter timeand lower in summer time. Mykonos was found to be the best site from windpower harnessing point of view. Moreover, the correlation between the percentagesof times the wind speed was above cut-in-speed and the measured mean windspeed for the three selected sites and the correlation between the aforementionedpercentages and the scale parameter c were examined and were found linear.
