Multiple types of fluctuations impact the collective dynamics of power grids and thus challenge their robust operation. Fluctuations result from processes as different as dynamically changing demands, energy trading and an increasing share of renewable power feed-in. Here we analyse principles underlying the dynamics and statistics of power grid frequency fluctuations. Considering frequency time series for a range of power grids, including grids in North America, Japan and Europe, we find a… 
Propagation of wind-power-induced fluctuations in power grids.
TLDR
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.
Stochastic properties of the frequency dynamics in real and synthetic power grids
The frequency constitutes a key state variable of electrical power grids. However, as the frequency is subject to several sources of fluctuations, ranging from renewable volatility to demand
How Decentral Smart Grid Control Limits Non-Gaussian Power Grid Frequency Fluctuations
TLDR
It is demonstrated that power grid frequency fluctuations are in general non-Gaussian, implying that large excursions are more likely than expected based on Gaussian modeling, and a decentral smart grid control scheme to limit these fluctuations is reviewed.
Heterogeneities in electricity grids strongly enhance non-Gaussian features of frequency fluctuations under stochastic power input.
TLDR
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.
Isolating the Impact of Trading on Grid Frequency Fluctuations
TLDR
It is found that trading at typical trading intervals such as full hours modifies the frequency fluctuation statistics, and that frequency deviations near the trading times are distributed more widely and thus extreme deviations are orders of magnitude more likely.
Phase and Amplitude Synchronization in Power-Grid Frequency Fluctuations in the Nordic Grid
TLDR
This paper presents a probabilistic procedure for estimating the response of the immune system to carbon dioxide in the presence of certain gases such as carbon dioxide and methane.
Spatio-temporal complexity of power-grid frequency fluctuations
Power-grid systems constitute one of the most complex man-made spatially extended structures. These operate with strict operational bounds to ensure synchrony across the grid. This is particularly
Stability and control of power grids with diluted network topology.
TLDR
This work demonstrates by numerical simulations that unstable frequency-synchronized states can be stabilized by feedback control and extends the study to include stochastic temporal power fluctuations and discusses the interplay of topological disorder and Gaussian white noise for various model configurations.

In the power grid, the frequency fundamentally indicates the health of the grid and shall stay within strict bounds to ensure reliable operation. Fluctuations arising from renewable energy sources
Towards realistic statistical models of the grid frequency
TLDR
This paper focuses on the grid frequency for the power system of Great Britain because the large share of renewables makes it a template for other power grids in the future and because it exhibits peculiar statistical properties, such as long-term correlations in fluctuations, periodicity, and bi-modal distribution of thegrid frequency.

On the stability and quality of power grids subjected to intermittent feed-in
Feed-in fluctuations induced by renewables are one of the key challenges to the stability and quality of electrical power grids. In particular short-term fluctuations disturb the system on a time
Short term fluctuations of wind and solar power systems
Wind and solar power are known to be highly influenced by weather events and may ramp up or down abruptly. Such events in the power production influence not only the availability of energy, but also
Turbulent character of wind energy.
TLDR
Evidence is shown that it is the complex structure of turbulence that dominates the power output for one single wind turbine as well as for an entire wind farm, and a stochastic model is proposed that converts wind speed signals into power output signals with appropriate multifractal statistics.
Large-deviation properties of resilience of power grids
We study the distributions of the resilience of power flow models against transmission line failures via a so-called backup capacity. We consider three ensembles of random networks, and in addition,
Escape routes, weak links, and desynchronization in fluctuation-driven networks.
TLDR
It is demonstrated how increased fluctuations, reduced damping, and reduced intertia may undermine the dynamical robustness of power grid networks.
Effects of dynamic-demand-control appliances on the power grid frequency.
TLDR
This work introduces a simple model to study the effects of DDC on the frequency of the power grid and finds that DDC can reduce small and medium-size fluctuations but it can also increase the probability of observing large frequency peaks due to the necessity of recovering pending task.
Node-wise robustness against fluctuations of power consumption in power grids
TLDR
It is numerically demonstrated that the supply of reactive power enhances the robustness of power grids under variation of effective power in one load node, and it is found that the shortest path length from generators is most highly correlated with the robusts of the load nodes.
Self-organized synchronization in decentralized power grids.
TLDR
Analysis of conditions enabling self-organized synchronization in oscillator networks that serve as coarse-scale models for power grids finds that whereas more decentralized grids become more sensitive to dynamical perturbations, they simultaneously become more robust to topological failures.
