Malicious Data Attacks on Smart Grid State Estimation: Attack Strategies and Countermeasures

摘要: The problem of constructing malicious data attack smart grid state estimation is considered together with countermeasures that detect the presence such attacks. For adversary, using a graph theoretic approach, an efficient algorithm polynomial-time complexity obtained to find minimum size unobservable When does not exist due restrictions meter access, attacks are constructed minimize residue energy while guaranteeing certain level increase mean square error. control center, computationally derived and localize generalized likelihood ratio test regularized by L_1 norm penalty on strength attack.
