Mitigating the risks of cyberattacks on cyber-physical power systems

作为国家关键基础设施的一部分，电力系统面临的相关问题是网络威胁。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，包括考虑网络攻击风险传播的攻击意图的离线风险建模，量化网络攻击风险传播的在线风险评估方法，以及减轻网络攻击风险的弹性控制策略。研究结果不仅将提高网络物理安全方面的知识，还将促进电网加速采用日益增加的可再生能源。

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.
