CPS: Medium: Collaborative Research: The CyberPhysical Challenges of Transient Stability and Security in Power Grids

提供高压电力的国家输电网络支撑着我们的社会，也是美国能源基础设施持续转型的核心。传输网络是非常庞大和复杂的工程系统，随着美国能源基础设施的转型，“保持照明”是一个基本的工程挑战，涉及设备的物理方面和控制，通信和运行系统的计算机的网络方面。该项目通过关注可能导致停电的电力网络不稳定性，开发了网络物理工程的新原理。 它提出了新的方法来分析这些不稳定性，并设计网络物理控制方法来监测，检测和减轻它们。控制必须在发电、负载、通信和设备状态的可变性和不确定性的存在下鲁棒地执行，以及在自然故障或恶意攻击引起的异常状态下。该研究产生了网络物理工程方法，专门帮助减轻电力系统停电，并更普遍地显示了设计强大的网络物理工程的前进方向。物理系统的环境特点是丰富的动态性和不确定性。教育和推广工作涉及高中、本科和研究生阶段的学生，并向公众以及工业、政府和大学的工程和应用科学界传播成果。

The national transmission networks that deliver high voltage electric power underpin our society and are central to the ongoing transformation of the American energy infrastructure. Transmission networks are very large and complicated engineering systems, and "keeping the lights on" as the transformation of the American energy infrastructure proceeds is a fundamental engineering challenge involving both the physical aspects of the equipment and the cyber aspects of the controls, communications, and computers that run the system. The project develops new principles of cyber-physical engineering by focusing on instabilities of electric power networks that can cause blackouts. It proposes novel approaches to analyze these instabilities and to design cyber-physical control methods to monitor, detect, and mitigate them. The controls must perform robustly in the presence of variability and uncertainty in electric generation, loads, communications, and equipment status, and during abnormal states caused by natural faults or malicious attacks.The research produces cyber-physical engineering methodologies that specifically help to mitigate power system blackouts and more generally show the way forward in designing robust cyber-physical systems in environments characterized by rich dynamics and uncertainty. Education and outreach efforts involve students at high school, undergraduate, and graduate levels, as well as dissemination of results to the public and the engineering and applied science communities in industry, government and universities.
