| Zusammenfassung |
Wind resource in the continental and offshore United States has been
reconstructed and characterized using metrics that describe, apart from
abundance, its availability, persistence and intermittency. The Modern Era
Retrospective-Analysis for Research and Applications (MERRA) boundary layer
flux data has been used to construct wind profile at 50 m,
80 m, 100 m, 120 m turbine hub heights. The wind
power density (WPD) estimates at 50 m are qualitatively similar to
those in the US wind atlas developed by the National Renewable Energy
Laboratory (NREL), but quantitatively a class less in some regions, but are
within the limits of uncertainty. The wind speeds at 80 m were
quantitatively and qualitatively close to the NREL wind map. The possible
reasons for overestimation by NREL have been discussed. For long tailed
distributions like those of the WPD, the mean is an overestimation and median
is suggested for summary representation of the wind resource.
The impact of raising the wind turbine hub height on metrics of abundance,
persistence, variability and intermittency is analyzed. There is a general
increase in availability and abundance of wind resource but there is an
increase in intermittency in terms of level crossing rate in low resource
regions. |
