The stochastic nature of power-grid frequency in South Africa
Leonardo Rydin Gorjão, Jacques Maritz
In this work, we explore two mechanisms that explain non-Gaussian behaviour of power-grid frequency recordings in the South African grid. We make use of a Fokker-Planck approach to…
Collective effects and synchronization of demand in real-time demand response
Chengyuan Han, Dirk Witthaut, Leonardo Rydin Gorjão +1
Sustainable energy systems require flexible elements to balance the variability of renewable energy sources. Demand response aims to adapt the demand to the variable generation, in…
MFDFA: Efficient Multifractal Detrended Fluctuation Analysis in Python
Leonardo Rydin Gorjão, Galib Hassan, Jürgen Kurths +1
Multifractal detrended fluctuation analysis (MFDFA) has become a central method to characterise the variability and uncertainty in empiric time series. Extracting the fluctuations…
Dynamic stability of electric power grids: Tracking the interplay of the network structure, transmission losses and voltage dynamics
Philipp C. Böttcher, Dirk Witthaut, Leonardo Rydin Gorjão
Dynamic stability is imperative for the operation of the electric power system. This article provides analytical results and effective stability criteria focusing on the interplay…
Analysis and data-driven reconstruction of bivariate jump-diffusion processes
Leonardo Rydin Gorjão, Jan Heysel, Klaus Lehnertz +1
We introduce the bivariate jump-diffusion process, comprising two-dimensional diffusion and two-dimensional jumps, that can be coupled to one another. We present a data-driven, non…
Complexity and irreducibility of dynamics on networks of networks
Leonardo Rydin Gorjão, Arindam Saha, Gerrit Ansmann +2
We study numerically the dynamics of a network of all-to-all-coupled, identical sub-networks consisting of diffusively coupled, non-identical FitzHugh--Nagumo oscillators. For a la…
Rotor-angle versus voltage instability in the third-order model for synchronous generators
Konstantin Sharafutdinov, Leonardo Rydin Gorjão, Moritz Matthiae +2
We investigate the interplay of rotor-angle and voltage stability in electric power systems. To this end, we carry out a local stability analysis of the third-order model which ent…
