论文摘要
我们提出了一种评估电力系统状态估计器的脆弱性的技术。我们的目的是确定具有很高潜力的测量值，这些测量值是虚假数据注射攻击的目标。从对手的角度来看，这样的测量必须显示以下特征：i）对变量估计产生影响，ii）损坏其测量值可能是未被发现的。此外，此类特征不应随着系统的运行条件而发生重大变化。我们的技术提供了一种具有此类特征的测量结果的系统方法。我们说明了我们关于4总线系统和新英格兰39个总线系统的方法论。
We propose a technique to assess the vulnerability of the power system state estimator. We aim at identifying measurements that have a high potential of being the target of false data injection attacks. From an adversary's point of view, such measurements have to show the following characteristics: i) being influential on the variable estimates, and ii) corrupting their measured values is likely to be undetected. Additionally, such characteristics should not change significantly with the system's operating condition. Our technique provides a systematic way of identifying measurements with such characteristics. We illustrate our methodology on a 4-bus system and the New England 39-bus system.
