Abstract

We consider a cyber-physical perspective to the problem of identifying and mitigating information corruption in smart grid systems. We study the problem of transient stability with distributed control using real-time data from geographically distributed phasor measurement units via a flocking-based modeling paradigm. We demonstrate how cyber corruption can be identified through the effective use of telltale physical couplings within the power system.We develop a novel witness-based cyber-physical protocol whereby physical coherence is leveraged to probe and identify phasor measurement unit data corruption and estimate the true information values for attack mitigation.
探测泄密物理:迈向网络物理协议,以减轻智能电网系统中的信息损坏
我们考虑从网络物理的角度来识别和减轻智能电网系统中的信息腐败问题。利用地理分布相量测量单元的实时数据,通过基于群集的建模范式,研究了分布式控制的暂态稳定问题。我们展示了如何通过有效利用电力系统内的物理耦合来识别网络腐败。我们开发了一种新的基于证人的网络物理协议,利用物理相干性来探测和识别相量测量单元数据损坏,并估计缓解攻击的真实信息值。
