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… 

Propagation of wind-power-induced fluctuations in power grids.

It is found that the variance of short-term fluctuations decays, for large inertia, exponentially with distance to the feed-in node, in agreement with numerical results both for a linear chain of nodes and the German transmission grid topology.

Heterogeneities in electricity grids strongly enhance non-Gaussian features of frequency fluctuations under stochastic power input.

The impact of wind power feed-in on the short-term frequency fluctuations in power grids is studied based on an Institute of Electrical and Electronics Engineers test grid structure, the swing equation for the dynamics of voltage phase angles, and a series of measured wind speed data.

Abstract. The importance of a high-order statistical feature of wind, which is neglected in common wind models, is investigated: non-Gaussian distributed wind velocity increments related to the

Identifying characteristic time scales in power grid frequency fluctuations with DFA.

This work aims to understand the fluctuations of the frequency on multiple time scales with a recently proposed method based on detrended fluctuation analysis that enables it to infer characteristic time scales and generate stochastic models.

Predictability of Power Grid Frequency

A weighted-nearest-neighbour (WNN) predictor is developed to investigate how predictable the frequency trajectories are and gains an increased understanding of the specific properties of different synchronous areas by interpreting the optimal prediction parameters in terms of the physical system.

An open data base of measurements of electric power grid frequencies across 17 locations in 12 synchronous areas on three continents is analyzed, showing how fluctuations change from local independent oscillations to a homogeneous bulk behaviour.
