Mitigating the risks of cyberattacks on cyber-physical power systems

作为国家关键基础设施的一部分，网络威胁是电力系统面临的一个相关问题。该项目将开发一个系统的理论来捕捉网络攻击对网络物理电力系统的动态风险传播。该理论着眼于网络物理电力系统的物理领域，包括考虑攻击意图的离线风险建模，用于网络攻击风险传播的在线风险评估方法，以及用于缓解网络攻击风险的弹性控制策略。这些成果不仅将促进网络物理安全方面的知识，还将促进电网中越来越多的可再生能源的加速采用。

Cyber threats are a pertinent issue facing power systems as part of national critical infrastructure. This project will develop a systematic theory to capture the dynamic risk propagation of cyberattacks on cyber-physical power systems. Focusing on the physical domain of cyber-physical power systems, the theory includes offline risk modelling with consideration of attack intentions for risk propagation of cyberattacks, an online risk assessment method to quantify the risk propagation of cyberattacks, and resilient control strategies to mitigate cyberattack risks. The outcomes will not only advance knowledge in cyber-physical security but also facilitate an accelerated adoption of the increasing renewable energy sources into the power grid.
