Sensitivity-based Vulnerability Assessment of State Estimation

Sensitivity-based Vulnerability Assessment of State Estimation

We propose a technique to assess the Crib Bedding vulnerability of the power system state estimation.We aim at identifying the measurements that have a high potential of being the target of false data injection attacks.From the perspective of the adversary, such measurements have the following characteristics: $igcirc!!!!!1$ being influential on the variable estimates; $igcirc!!!!!2$ corrupting their measured values is likely to be undetected.Additionally, such characteristics should not change significantly with the system operation condition.The proposed technique provides a Corner Sofa systematic way of identifying the measurements with such characteristics.

We illustrate our methodology on a 4-bus system, the New England 39-bus system, and the IEEE 118-bus test system, respectively.
