摘要:
由于信息技术的高集成度,电力系统更容易受到网络攻击。本文证明通过向测量数据中注入虚假数据可以掩盖部分线路故障。攻击成功的关键在于:1) 注入的虚假数据符合KCL和KVL,以避免被状态估计中的坏数据检测程序发现;2) 增大残差使得PMU数据无法检测到线路故障。通过建立二次规划问题确定最优攻击向量以最大化故障线路的残差。IEEE 39节点系统用于验证该掩盖方案。
英文摘要:
Power systems become more prone to cyber-attacks due to the high integration of information technologies. In this paper, we demonstrate that the outages of some lines can be masked by injecting false data into a set of measurements. The success of the topology attack can be guaranteed by making that: 1)the injected false data obeys KCL and KVL to avoid being detected by the bad data detection program in the state estimation; 2)the residual is increased such that the line outage cannot be detected by PMU data. A quadratic programming problem is set up to determine the optimal attack vector that can maximize the residual of the outaged line. The IEEE 39-bus system is used to demonstrate the masking scheme.
