Impacts of node arrangements on synchronization of a ring oscillatory power network

Abstract Power network refers to a complex system that relies on the interactions between generators and consumers. This paper mainly studies the influence of consumers and generators arrangement on the synchronization of a ring-coupled power network. It is shown by numerical results that node arrangement strategies play a key role in the collective behavior of ring power network. Furthermore, it can be discovered that different arrangements of the consumer and generator nodes on a ring leads to different threshold of coupling strength for frequency synchronization. More specifically, the closer the nodes, which are more heterogeneous on a ring, are to each other, the stronger the synchronizability of power network is. On the contrary, the closer the nodes, which are less heterogeneous, are to each other, the weaker the synchronizability of power network is. The results show that the strategies of generator and consumer nodes arrangement have influence on the synchronization stability and highlight the importance of structural organization of network in synchronization dynamics.
