Collective nonlinear dynamics and self-organization in decentralized power grids

D Witthaut, F Hellmann, J Kurths, S Kettemann… - Reviews of modern …, 2022 - APS
The ongoing transition to renewable energy supply comes with a restructuring of power
grids, changing their effective interaction topologies, more and more strongly decentralizing …

Stability and control of power grids with diluted network topology

L Tumash, S Olmi, E Schöll - Chaos: An Interdisciplinary Journal of …, 2019 - pubs.aip.org
We consider sparse random networks of Kuramoto phase oscillators with inertia in order to
mimic and investigate the dynamics emerging in high-voltage power grids. The …

Effect of disorder and noise in shaping the dynamics of power grids

L Tumash, S Olmi, E Schöll - Europhysics Letters, 2018 - iopscience.iop.org
The aim of this paper is to investigate complex dynamic networks which can model high-
voltage power grids with renewable, fluctuating energy sources. For this purpose we use the …

Turbulence coherence and its impact on wind-farm power fluctuations

N Tobin, LP Chamorro - Journal of Fluid Mechanics, 2018 - cambridge.org
Using a physics-based approach, we infer the impact of the coherence of atmospheric
turbulence on the power fluctuations of wind farms. Application of the random-sweeping …

Dynamic control of intermittent renewable energy fluctuations in two-layer power grids

S Olmi, CH Totz, E Schöll - arXiv preprint arXiv:2111.14483, 2021 - arxiv.org
In this work we model the dynamics of power grids in terms of a two-layer network, and use
the Italian high voltage power grid as a proof-of-principle example. The first layer in our …

Machine learning of power grid frequency dynamics and control: prediction, explanation and stochastic modelling

J Kruse - 2023 - kups.ub.uni-koeln.de
A reliable supply of electric power is not a matter of course. Power grids enable the transport
of power from generators to consumers, but their stable operation constantly requires …

Influence of disorder and noise in controlling the dynamics of power grids

L Tumash, S Olmi, E Schöll - IFAC-PapersOnLine, 2018 - Elsevier
We investigate complex dynamic networks which can model high-voltage power grids with
renewable, fluctuating energy sources. The Kuramoto model with inertia is used to model …
