Control of synchronization in two-layer power grids — •Carl H. Totz¹, Simona Olmi², and Eckehard Schöll¹ — ¹Institut für Theoretische Physik, TU Berlin, Hardenbergstr. 36, D-10623 Berlin — ²INRIA Sophia Antipolis Méditerranée, 2004 Route des Lucioles, 06902 Valbonne, France

The dynamics of a two-layer network modeling the Italian high voltage power grid is investigated: the first layer represents the generators and consumers, while the second layer represents a dynamic communication network between generators that serves as controller of the first layer. The dynamics of the power grid is modeled by the Kuramoto model with inertia, while the second layer provides a control signal P_i^c for each generator to improve frequency synchronization within the power grid.

We investigate different realizations of the communication layer topology and different control methods. The two-layer system is tested for different perturbation scenarios (disconnecting some generators, increasing demand of consumers, generators with stochastic output) and, irrespectively of the applied perturbation, we find that the control scheme aimed to synchronize the frequency of the generators with the consumers is very efficient against almost all perturbation scenarios.
