Physically Consistent Null Space Alignment for Detection of Low-Magnitude False Data Injection Attacks
arXiv:2606.08473v1 Announce Type: new Abstract: False data injection attacks (FDIAs) introducing small measurement perturbations can still cause large deviations in power system state estimation when the injected signals align with the pseudo-null space of the system model. Existing model- and data-driven detectors may fail to identify such low-magnitude but high-impact attacks because residual tests ignore changes hidden in the pseudo-null space, while subspace learning methods capture correlation patterns without enforcing physical consistency. This paper proposes Physically Consistent Null
The increasing integration of AI and complex algorithms into critical infrastructure like power systems necessitates robust defense mechanisms against sophisticated cyber threats.
Sophisticated false data injection attacks (FDIAs) can severely disrupt critical infrastructure, making advanced detection methods vital for national security and economic stability.
This paper introduces a physically consistent method to detect low-magnitude FDIAs that were previously difficult to identify, enhancing the security posture of power grids.
