The ongoing transition to renewable energy supply comes with a restructuring of power
grids, changing their effective interaction topologies, more and more strongly decentralizing …

Stable operation of an electric power system requires strict operational limits for the grid
frequency. Fluctuations and external impacts can cause large frequency deviations and …

Effective frequency control in power grids has become increasingly important with the
increasing demand for renewable energy sources. Here, we propose a novel strategy for …

Decarbonization in the energy sector has been accompanied by an increased penetration of
new renewable energy sources in electric power systems. Such sources differ from …

We discuss the frequency of desynchronization events in power grids for realistic data input.
We focus on the role of time correlations in the fluctuating power production and propose a …

Serious fluctuations caused by disturbances may lead to instability of power systems. With
the disturbance modeled by a Brownian motion process, the fluctuations are often described …

Symmetries are widespread in physical, technological, biological, and social systems and
networks, including power grids. The swing equation is a classic model for the dynamics of …

Fluctuations of state variables play a pivotal role in analyzing small signal stability of the
power system due to the integration of renewable energy sources. This paper develops a …

One of the most fundamental characteristic of a complex system is its size (or volume),
which, in many modelling, is represented by the number of its individual components …

We study the swing equation in the case of a multilayer network in which generators and
motors are modeled differently; namely, the model for each generator is given by second …
