Improving power-grid systems via topological changes, or how self-organized criticality can help stability
Géza Ódor, István Papp, Kristóf Benedek +1
Cascade failures in power grids occur when the failure of one component or subsystem causes a chain reaction of failures in other components or subsystems, ultimately leading to a…
Dynamical heterogeneity and universality of power-grids
Bálint Hartmann, Géza Ódor, István Papp +3
While weak, tuned asymmetry can improve, strong heterogeneity destroys synchronization in the electric power system. We study the level of heterogeneity, by comparing large high vo…
Heterogeneity effects in power-grid network models
Géza Ódor, Bálint Hartmann
We have compared the phase synchronization transition of the second order Kuramoto model on 2D lattices and on large, synthetic power grid networks, generated from real data. The l…
Griffiths phases in infinite-dimensional, non-hierarchical modular networks
Wesley Cota, Géza Ódor, Silvio C. Ferreira
Griffiths phases (GPs), generated by the heterogeneities on modular networks, have recently been suggested to provide a mechanism, rid of fine parameter tuning, to explain the crit…
Griffiths effects of the susceptible-infected-susceptible epidemic model on random power-law networks
Wesley Cota, Silvio C. Ferreira, Géza Ódor
We provide numerical evidence for slow dynamics of the susceptible-infected-susceptible model evolving on finite-size random networks with power-law degree distributions. Extensive…
Spectral analysis and slow spreading dynamics on complex networks
Géza Ódor
The Susceptible-Infected-Susceptible (SIS) model is one of the simplest memoryless system for describing information/epidemic spreading phenomena with competing creation and sponta…
