摘要/Abstract

摘要： 为了准确检测由网络攻击引发的各种跨空间连锁故障，提出了一种考虑攻击损益的场站级跨空间连锁故障早期预警方法。首先，根据跨空间连锁故障演化机理讨论了故障早期预警的工作原理，建立故障早期预警的数学模型；进而，提出误用检测与异常检测融合的场站级跨空间连锁故障检测方法；最后，在基于CEPRI-36节点的电网信息物理系统仿真环境中，模拟网络攻击引发的跨空间连锁故障并利用所提方法给予早期预警，验证了所提方法的有效性。

Abstract: In order to accurately detect the cascading failures across space (CFAS) caused by cyber attacks in grid cyber-physical systems (GCPS), a station-level early warning method for CFAS is proposed based on attack gain and cost principle (AGCP). Firstly, the working principle of CFAS early warning is discussed according to the evolution mechanism of CFAS, and a mathematical model of CFAS early warning is established. And then, a station-level CFAS detection method is proposed based on the integration of misuse detection and anomaly detection. Finally, to verify the effectiveness of the proposed CFAS early warning method, a variety of CFAS are simulated in a CEPRI-36 bus GCPS simulation environment, and the early warning is given by using the proposed CFAS early warning method.

Key words: grid cyber-physical systems, cyber attacks, cascading failures across space, attack gain and cost, early warning
