Sensitivity-based Vulnerability Assessment of State Estimation

Sensitivity-based Vulnerability Assessment of State Estimation

Blog Article

We propose a technique to assess the vulnerability of the power system state estimation.We aim at identifying the measurements that have a high potential of being Anti-Gas 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 systematic way of identifying the measurements with such characteristics.We illustrate our methodology on a 4-bus system, the New England 39-bus THUMB CONTROL system, and the IEEE 118-bus test system, respectively.
