简介
With increasing terrorism and sabotage activities, the power grid is becoming more vulnerable to various kinds of cyber and physical attacks. Coordination between the attacks could bring higher impacts on the power system, as evidenced by the 2015 Ukrainian power system cyberattack. There is limited study in existing literature about possible coordinated attack scenarios and the detailed mathematical modeling of them. To prevent future coordinated attacks against power systems, in this paper the cyber-physical security of the power system is analyzed and probable coordinated attack scenarios are proposed. Two typical attack coordination examples are studied in detail: the coordination between load redistribution (LR) attack and attacking generators; and the coordination between LR attack and attacking lines. They are formulated as bilevel optimization problems, where the attacker at the upper level aims to …
