分布式状态估计对互联电力系统的高效可靠运行起着至关重要的作用。因此，它的安全性是一个重大问题。在这项工作中，我们展示了攻击者在互联系统中破坏单个控制中心可以通过注入虚假数据对最先进的分布式状态估计发起拒绝服务攻击，因此，它可以使整个系统失明。我们提出了一种基于本地测量的全分布式攻击检测方案来检测这种拒绝服务攻击。然后，我们提出了一种完全分布式的攻击定位方案，该方案依赖于区域对攻击位置的信念，并对电力系统拓扑进行推理，以识别最可能的攻击位置。我们在IEEE 118总线电源系统上验证了这两种算法。
Distributed state estimation will play a central role in the efficient and reliable operation of interconnected power systems. Therefore, its security is of major concern. In this work we show that an attacker that compromises a single control center in an interconnected system could launch a denial of service attack against state-of-the-art distributed state estimation by injecting false data, and consequently, it could blind the entire system. We propose a fully distributed attack detection scheme based on local measurements to detect such a denial of service attack. We then propose a fully distributed attack localization scheme that relies on the regions' beliefs about the attack location, and performs inference on the power system topology to identify the most likely attack location. We validate both algorithms on the IEEE 118 bus power system.
