摘要
为了得出小世界网络特性对电网发生连锁故障的影响,文中对几个具有小世界特征的电网和几个具有随机网络特征的电网进行了仿真分析,结果发现无论是具有小世界网络特征的电网还是具有随机网络特征的电网,在一定的条件下都表现出自组织临界性,即发生连锁故障的“故障规模—故障概率”分布曲线呈现出幂律特征。
For the sake of determining the impact of small-world property on probability of occurring cascading failures in power systems, the cascading failures are simulated in several power systems among which some have small-world property and the others have stochastic network property. The result shows that power systems with either small-world property or stochastic network property will both indicate self-organized criticality under specific conditions, that is, the blackout sizes show a power law distribution.
