| Zusammenfassung |
| We consider here wind speed time series and the aggregate output wind power
from a wind farm. We study their scaling statistics in the framework of fully
developed turbulence and Kolmogorov's theory. We estimate their Fourier power
spectra and consider their scaling properties in the physical space. We show
that the atmospheric wind speed and the aggregate power output from a wind
farm are intermittent and multifractal over a wide range of scales. The
coupling between simultaneous data of the wind speed and aggregate power
output is investigated through a joint multifractal description using the
generalized correlation functions (GCFs). This multiscaling test is compatible
with a linear relation between the wind speed and the aggregate power output
fluctuations for timescales T ⩾ 103 s ≃ 15 min. |
