# Long Wavelength Coherency in Well Connected Electric Power Networks

@article{Fritzsch2022LongWC, title={Long Wavelength Coherency in Well Connected Electric Power Networks}, author={Julian Fritzsch and Philippe Jacquod}, journal={IEEE Access}, year={2022}, volume={10}, pages={19986-19996} }

We investigate coherent oscillations in large scale transmission power grids, where large groups of generators respond in unison to a distant disturbance. Such long wavelength coherent phenomena are known as inter-area oscillations. Their existence in networks of weakly connected areas is well captured by singular perturbation theory. However, they are also observed in strongly connected networks without time-scale separation, where applying singular perturbation theory is not justified. We…

This work investigates synchronizable network-coupled dynamical systems such as high-voltage electric power grids and coupled oscillators on complex networks and shows that, when the coupling matrix is Laplacian, key players are peripheral in the sense of a centrality measure defined from effective resistance distances.

The analysis shows that the first-order approximation of the diffusion and convergence rates is independent of the topologies of the individual graphs; the rates depend only on the number of nodes in each graph and the topology of the connecting edges.
