电力系统连锁故障研究模型的比较
Comparing Different Models for Investigating Cascading Failures in Power Systems
摘要：
本文主要对描述电力系统连锁故障的三种不同模型进行比较。具体而言，这些模型在表征电力网络的物理特性和计算支路潮流方面是不同的。应用最优控制方法对这些模型进行辨识，以确定导致最坏情况下电网连锁故障的临界扰动。然后通过分析临界扰动和级联过程对这些模型进行了比较。IEEE 9节点系统的比较结果表明，电力网络的物理和电气特性对连锁故障的演化起着至关重要的作用，在应用该模型分析连锁故障时，有必要适当考虑这些特性。
英文摘要：
This paper centers on the comparison of three different models that describe cascading failures of power systems. Specifically, these models are different in characterizing the physical properties of power networks and computing the branch power flow. Optimal control approach is applied on these models to identify the critical disturbances that result in the worst-case cascading failures of power networks. Then we compare these models by analyzing the critical disturbances and cascading processes. Significantly, comparison results on IEEE 9 bus system demonstrate that physical and electrical properties of power networks play a crucial role in the evolution of cascading failures, and it is necessary to take into account these properties appropriately while applying the model in the analysis of cascading blackout.
