Assessing the robustness of critical behavior in stochastic cellular automata
Sidney Pontes-Filho, Pedro Lind, Stefano Nichele
There is evidence that biological systems, such as the brain, work at a critical regime robust to noise, and are therefore able to remain in it under perturbations. In this work, w…
Change of persistence in European electricity spot prices
Leonardo Rydin Gorjão, Dirk Witthaut, Pedro G. Lind +1
The European Power Exchange has introduced day-ahead auctions and continuous trading spot markets to facilitate the insertion of renewable electricity. These markets are designed t…
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…
Normal behaviour models for wind turbine vibrations: An alternative approach
Pedro G. Lind, Luis Vera-Tudela, Matthias Wächter +2
The identification of abnormal behaviour in mechanical systems is key to anticipate and avoid their potential failure. Thus wind turbine health is commonly assessed monitoring seri…
