| 摘 要： | 以电力系统的停电事故为例,提出一种节点具有能量耗散和扩容行为的级联故障模型,并分别在二维规则网络和无标度网络上对该系统的演化过程进行计算机模拟.结果表明,在两种不同结构的网络中系统的演化过程都出现了自组织临界现象,说明网络中节点能量的耗散及容量的扩充是导致电力系统出现自组织临界现象的重要因素.此外,还发现无标度网络中的最大级联故障规模要远大于二维规则网络中的级联故障规模.

| Abstract: | A failure cascading model for power systemes is proposed,in which energy dissipation and capability expansion are considered.Simulations are performed on both regular grids and scale-free networks.Self-organized critical phenomenon is observed in both cases.It means that energy dissipation and capability expansion are important factors in self-organized critical status.In addition,it shows that the maximum size of cascading failures in scale-free networks is much larger than that in regular networks. |

| Keywords: | self-organized criticality cascading failure power system |
