False Data Injection Attacks Using Matrix Recovery and PARAFAC in Smart Grid

Abstract— Existing researches demonstrate that state estimation result could be compromised by malicious attacks. However, to construct the attack vectors, a usual assumption in most works is that the attacker has perfect information regarding the topology even such information is difficult to acquire in practice. Recent research shows that Parallel Factor Analysis (PARAFAC) can be used to drive the linear structure matrix of the smart grid which can be used to carry out undetectable attacks. However, we found that the above PARAFAC based blind attack strategy is only feasible in the environment with Gaussian noises. If there are outliers (device malfunction or communication errors), the Bad Data Detector will easily detect the attack. Hence, we propose a robust PARAFAC based blind attack strategy that one can use matrix recovery to circumvent the outlier problem and construct stealthy attack vectors. The proposed attack strategies are tested with IEEE 14-bus system. Simulations verify the feasibility of the proposed method.
