How trading impacts distribution in complex power grids — •Sebastian Klipp1, Dirk Witthaut1, and Marc Timme1,2 — 1Network Dynamics, Max Planck Institute for Dynamics and Self-Organization, 37077 Göttingen — 2Faculty of Physics, University of Göttingen
Instabilities in the collective dynamics of power grids may induce transmission line overloads or even large-scale power outages. One possible source of instability is the energy trading market that modifies locations, times, and volumes of electric power generation and demand. Here we investigate how economic factors can influence the distribution of energy-flow in a power-grid. We reveal that and how the interdependence of the economic and the physical network can induce dynamic instabilities and explain the mechanisms underlying them. These results offer a complementary perspective on the development of smart power grids and the integration of renewable energies.
