中文摘要：

本文对由电力网络组成的簇网络的同步和稳定性进行研究。首先通过观察簇网络各项参数的变化，研究了簇间连接数对簇网络同步性能的影响。结果表明：簇间连接数越大，簇网络的同步性能越好、同步临界耦合强度越小、系统可承受的最大扰动强度也越大；然后将簇网络系统与单一电力系统进行比较分析，结果表明：子网间的不同结构会对簇网络的同步及稳定性产生较大影响。

英文摘要：

In this paper, the synchronization and stability of the cluster network composed of power grids are studied. Firstly, the influence of the number of inter-cluster connections on the synchronization performance is studied by observing the variation of the parameters of the cluster network. The results show that a larger the number of connections between the clusters leads to a better the synchronization performance of the entire cluster networks, a smaller the corresponding synchronous critical coupling strength and a greater maximum disturbance intensity that the system can withstand. Then, a comparative analysis is made between the cluster network system and the single power system. The results show that the different structures of the subnet have a great influence on the synchronization and stability of the cluster network.
