近年来，针对电力系统的网络攻击得到了广泛的研究。到目前为止，有几项研究集中在欺骗状态估计器的方法上，以便得到错误的估计。另一方面，网络拓扑结构和测量设计对网络攻击可检测性的作用尚未得到广泛研究。这项工作检查了测量和网络拓扑结构，以识别针对有针对性的网络攻击的漏洞。具体而言，它考虑了杠杆测量，其误差通常不容易检测到，因此当它们带有显著误差时，它们可能会使估计量产生偏差。该文件还说明，这种脆弱性可以解决的战略性取代这些测量相量测量单元（PMU）。
Cyber-attacks against power systems have been widely researched in recent years. Several studies have so far focused on ways of deceiving the state estimator so that the resulting estimates would be wrong. On the other hand, the role of network topology and measurement design on detectability of cyber-attacks has not been widely investigated. This work examines the measurements and network topology to identify vulnerabilities against targeted cyber-attacks. Specifically, it considers the leverage measurements, whose errors are typically not easily detected and therefore they may bias estimators when they carry gross errors. The paper also illustrates that this vulnerability can be addressed by strategic replacement of few of these measurements by phasor measurement units (PMUs).
