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…
Revisiting and modeling power-law distributions in empirical outage data of power systems
Bálint Hartmann, Shengfeng Deng, Géza Ódor +1
The size distribution of planned and forced outages and following restoration times in power systems have been studied for almost two decades and has drawn great interest as they d…
Synchronization dynamics on the EU and US power grids
Géza Ódor, Shengfeng Deng, Bálint Hartmann +1
Dynamical simulation of the cascade failures on the EU and USA high-voltage power grids has been done via solving the second-order Kuramoto equation. We show that synchronization t…
How Does the Vulnerability of an Evolving Power Grid Change?
Balint Hartmann
In this paper the seven-decade historical dataset of the Hungarian power system is used to perform vulnerability assessment applying a complex network approach.
Searching for small-world and scale-free behaviour in long-term historical data of a real-world power grid
Bálint Hartmann, Viktória Sugár
In this paper the authors use the 70-year-long historical dataset of the Hungarian power grid to perform complex network analysis, which is the first attempt to evaluate small-worl…
Power-law distributions of dynamic cascade failures in power-grid models
Géza Ódor, Bálint Hartmann
Power-law distributed cascade failures are well known in power-grid systems. Understanding this phenomena has been done by various DC threshold models, self-tuned at their critical…
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…
