一旦关键变电站受到威胁,攻击代理可以在其对等方之间进行协调,利用本地控制设备来策划最大限度地破坏。对于防御者来说,列举和识别所有数字中继以确定系统性风险是至关重要的。通过受损继电器的任何破坏性切换组合都可能导致误操作或对系统产生直接影响。这些攻击初始事件的结果可能会导致网格级联失败。本文结合变电站继电保护的停电等级及其相应的严重风险指数,对继电保护的临界性进行了量化。根据变电站的继电保护类型和母线配置,研究了常用的继电保护方案,如母线差动、方向过流和距离继电保护。这一初步工作还为灵敏度分析提供了三种确定概率的方法。使用IEEE测试系统对提出的风险指数进行了评估。

英文摘要:
  Once critical substations are compromised, attack agents can coordinate among their peers to plot for maximizing disruption using local control devices. For defenders, it is critical to enumerate and identify all digital relays to determine the systemic risks. Any combination of disruptive switching via the compromised relays can result in misoperation or immediate effect to the system. The resulting consequence of these attack's initial events would possibly incur cascading failure to a grid. This paper quantifies the criticality of substation protective relays with the combination of the outage level and its corresponding severity risk index. The proposed hypothesized outages are based on the type of protective relaying, bus configuration of a substation, and commonly implemented relaying schemes, such as bus differential, directional overcurrent, and distance relays, are studied. This preliminary work also provides three approaches of determination in probabilities for sensitivity analysis. The proposed risk indices are evaluated using IEEE test systems.
