False Data Injection Attacks on Phasor Measurements That Bypass Low-rank Decomposition

摘要

This paper studies the vulnerability of phasor measurement units (PMUs) tofalse data injection (FDI) attacks. Prior work demonstrated that unobservableFDI attacks that can bypass traditional bad data detectors based on measurementresiduals can be identified by detector based on low-rank decomposition (LD).In this work, a class of more sophisticated FDI attacks that captures thetemporal correlation of PMU data is introduced. Such attacks are designed witha convex optimization problem and can always bypass the LD detector. Thevulnerability of this attack model is illustrated on both the IEEE 24-bus RTSand the IEEE 118-bus systems.
