电网在动态诱发脆弱性下的恢复能力下降
Decreased resilience in power grids under dynamically induced vulnerabilities
摘要：
在本文中，一种方法的启发，债券和网站渗流方法应用于对电网故障的恢复力的估计。我们的方法包括动态和结构基础的脆弱性措施，试图找到更多的见解拓扑结构和动态之间的关系，在复杂网络的二阶仓本模型。作为数值模拟的测试用例，我们使用哥伦比亚电力传输系统的真实拓扑结构，以及具有空间嵌入的随机生成的网络。据观察，通过集中攻击这些动态的脆弱性，电网变得，在一般情况下，更容易达到完全停电的状态，在节点删除程序的情况下，它是由网络中的功率分布的均匀性的条件。
英文摘要：
In this paper, a methodology inspired on bond and site percolation methods is applied to the estimation of the resilience against failures in power grids. Our approach includes vulnerability measures with both dynamical and structural foundations as an attempt to find more insights about the relationships between topology and dynamics in the second-order Kuramoto model on complex networks. As test cases for numerical simulations, we use the real-world topology of the Colombian power transmission system, as well as randomly generated networks with spatial embedding. It is observed that, by focusing the attacks on those dynamical vulnerabilities, the power grid becomes, in general, more prone to reach a state of total blackout, which in the case of node removal procedures it is conditioned by the homogeneity of power distribution in the network.
