Turbulence driving wind energy

Joachim Peinke

Short Abstract
The main focus of the talk will be on the impact of turbulent wind conditions on the conversion of wind energy. It will shown that the multifractal features of turbulence improve the actual wind classification. Based on extreme value statistics and intermittency new quantities to characterize short term wind gusts will be proposed. The impact of such turbulent gusts on loads and on fluctuating power production will be shown. Finally based on modern stochastic time series analysis a method to estimate a new power curve of a wind turbine will be explained.

Besides these scientific aspects an outlook on the promising developments of wind energy and challenges of offshore wind energy to become one major source for our electricity demand will be given.
