@article{Haehne2018TheFO, title={The footprint of atmospheric turbulence in power grid frequency measurements}, author={Hauke Haehne and Jannik Schottler and M. Waechter and Joachim Peinke and Oliver Kamps}, journal={Europhysics Letters}, year={2018}, volume={121} }

Fluctuating wind energy makes a stable grid operation challenging. Due to the direct contact with atmospheric turbulence, intermittent short-term variations in the wind speed are converted to power fluctuations that cause transient imbalances in the grid. We investigate the impact of wind energy feed-in on short-term fluctuations in the frequency of the public power grid, which we have measured in our local distribution grid. By conditioning on wind power production data, provided by the ENTSO…
