A Method for Generating Virtual Data Injection Attacks in Power Systems Considering Power Flow and Topological Constraints
针对传统虚假数据注入攻击将量测值与状态变量间的非线性函数关系近似作为直流模型进行处理,且未考虑交流潮流和不完整拓扑信息的问题,文章提出一种虚拟数据注入攻击(dummy data injection attack,DDIA)生成方法.首先,详细分析交流状态评估及不良状态检测方法,为后续DDIA生成提供理论依据;其次,提出了计及交流潮流和拓扑约束的DDIA生成方法,并考虑DDIA的虚拟性特征,通过确保量测数据与被攻击数据距离最小的数据点,即可构造被篡改的量测数据;最后,在IEEE 14、IEEE 118和IEEE 300 节点系统上进行攻击模拟,结果表明,提出的虚拟数据注入攻击十分隐蔽且对电力系统的稳定运行造成了严重影响.
To address the limitations of traditional false data injection attacks—such as approximating the nonlinear relationship between measurements and state variables as a DC model without considering AC power flow and incomplete topology information,this paper proposes a virtual data injection attack generation method.First,it conducts a detailed analysis of AC state estimation and bad data detection methods to provide a theoretical foundation for subsequent virtual data injection attack generation.Second,it introduces a DDIA generation method that accounts for AC power flow and topology constraints,while also leveraging the virtual nature of DDIA by selecting the measurement data point with the smallest distance to the attacked data to construct tampered measurements.Finally,attack simulations are conducted on the IEEE 14 bus,IEEE 118 bus,and IEEE 300 bus systems,demonstrating that the proposed virtual data injection attack is highly covert and severely impacts the stable operation of power systems.
