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