考虑负荷虚假数据注入攻击的电力信息物理系统防御策略
Cyber-physical system defense strategy considering loaded false data injection attacks
摘要
Abstract
In order to achieve the higher security level of power system in context of cyber-physical fusion, the detailed procedures of attacks and defenses are studied in this paper based on the three-level framework of game theory. The optimal defense strategy and the minimal load loss expectation under the limited defense resources are also investigated. Firstly, the optimal defense strategy is modeled in the upper defender model to reduce the vulnerability of power grid. Then, the middle attacker model is established to maximize the attack effects. In the lower-level, the optimal dispatch is used to reduce the attack loss. To solve the problem efficiently, mixed integer programming method combined with traversal thought based genetic algorithm is employed to calculate the optimal results. The feasibility of the proposed approach is validated through a benchmark case study.关键词
