Severe Cyber Attack for Maximizing the Total Loadings of Large-Scale Attacked Branches

A Novel Bilevel False Data Injection Attack Model Based on Pre- and Post- Dispatch

“…Table II shows the number of overloading branches in the two systems. We can see that in the 14-bus system, our method overloads one branch, while both methods in [3], [4] overload two branches. However, in the 39-bus system, our method can obviously overload more branches than other two methods.…”

“…However, in the 39-bus system, our method can obviously overload more branches than other two methods. Especially, the method in [4] does not cause any branch overload. Moreover, we give the space distribution of overloaded branches caused by our method in the IEEE 39-bus system, as shown in Fig.…”

“…We can see that the three methods result in different generation outputs for the same generator node, leading to the different operation cost. In the 14-bus system, the two methods in [3], [4] result in the total operation costs of $4427.291 and $4536.500, respectively. In comparison, the proposed method results in the total operation cost of $4328.700.…”

“…CASE STUDY We employ IEEE 14-bus and IEEE 39-bus systems to verify the effectiveness of the proposed method. To analyze the advantages of the proposed method, we compare our method with the existing bilevel methods in [3], [4] where all the system information is required to model FDI attacks.…”

Bilevel Model for Protection-Branch Measurements-Based Topology Attack Against DC and AC State Estimations

“…On this basis, some studies explored how to maximize the effect and improve efficiency of the immediate attacks. A bilevel linear programming model was constructed to cause line overloading and maximize the total loadings in all overloaded lines [11]. A fast solution in determining the attack vectors by just solving one linear programing problem was presented in [12].…”
