Arbitrary-order finite-time corrections for the Kramers-Moyal operator
Leonardo Rydin Gorjão, Dirk Witthaut, Klaus Lehnertz +1
With the aim of improving the reconstruction of stochastic evolution equations from empirical time-series data, we derive a full representation of the generator of the Kramers-Moya…
Heterogeneities in electricity grids strongly enhance non-Gaussian features of frequency fluctuations under stochastic power input
Matthias F. Wolff, Katrin Schmietendorf, Pedro G. Lind +3
Stochastic feed-in of fluctuating renewable energies is steadily increasing in modern electricity grids and this becomes an important risk factor for maintaining power grid stabili…
Power grid stability under perturbation of single nodes: Effects of heterogeneity and internal nodes
Matthias Wolff, Pedro G. Lind, Philipp Maass
Non-linear equations describing the time evolution of frequencies and voltages in power grids exhibit fixed points of stable grid operation. The dynamical behaviour after perturbat…
