Influence of network topology in shaping the dynamics of power grid networks — •Halgurd Taher, Simona Olmi, and Eckehard Schöll — Institut fuer Theoretische Physik, Sekr. EW 7-1, TU Berlin, Hardenbergstr. 36, D-10623 Berlin

The increase of the inclusion of renewable energy sources into the power grid is rather a paradigm change for the entire European power grid, bringing new challenges for power grid operation. The reason behind this is the fact that the power output of renewable energy sources typically strongly fluctuates and, furthermore, the possible geographical locations for power plants based on renewable energies depend on geographical factors, thus including different forms of perturbations into the network. In this talk we investigate the role played by topology in shaping the dynamics of the German power grid and we present a new investigation method able to highlight the instabilities of the system. Based on the knowledge of the unstable nodes and directions suggested by the application of the Lyapunov vector, we are thus able to design a control method that enhances the synchronization and stabilizes the network, acting on small number of nodes/links. This minimal intervention suggests a procedure to control real grids that allows to save time, money and energy.
