Influence of edge additions on the synchronizability of oscillatory power networks

摘要

The influence of edge-adding number and edge-adding distance on synchronization of oscillatory power network is investigated. Here we study how the addition of new links impacts the emergence of synchrony in oscillatory power network, focusing on ring, and treelike topologies. Numerical simulations show that the impact of distance of adding edges whether homogeneous (generators to generators or consumers to consumers) or heterogeneous (generators to consumer nodes and vice versa) edges is not obvious on the synchronizability of oscillatory power network. However, for the edge-adding number, it is observed that the bigger heterogeneous edge-adding number, the stronger synchronizability of power network will be. Furthermore, the homogeneous edge-adding number does not affect the synchronizability of oscillatory power network. (C) 2016 Elsevier B.V. All rights reserved.
