CPS: Small: Collaborative Research: CYDER: CYbersecure Distribution systems with power Electronically interfaced Renewables

该项目的研究目标是设计一种全面的方法，用于配电系统的网络安全监测和缓解，该系统具有大量易于受到网络攻击的动态设备以及电力电子接口的可再生发电机组。电力电子接口由于其对不期望的干扰的敏感性而使配电系统的控制和操作复杂化。通过促进更安全的电力系统，这项工作有助于提高配电系统对极端事件的弹性，这符合美国的国家优先事项。此外，这项工作促进了教学和学习（一）通过几个方案，包括在行业网站举办为期一周的实习教育和培训研究生;（二）通过会议演示文稿和出版物传播我们的工作成果;（三）在两门课程的教学大纲中引入重大更新。这项工作还通过积极征聘，增加了代表性不足的少数群体的参与。该项目的总体研究目标是设计一种全面的方法，用于网络安全监测和缓解系统中的大量动态设备，这些设备容易受到网络攻击。为了证明我们提出的算法的性能，我们研究了它们在配电系统中的应用，作为一个关键的网络基础设施，其中包括变电站，馈线设备和智能电表。电网对信息和通信技术（ICT）的日益依赖大大增加了其对网络攻击的脆弱性。一个主要的关注领域是电网所依赖的监控和控制功能的监控和数据采集（SCADA）系统的安全性。为了应对这些挑战，我们的具体目标是（i）检测配电系统上的网络威胁，（ii）通过基于多代理的算法以及轨迹整形和频率调节策略，缓解和响应网络入侵，特别是与电力电子接口的可再生能源，及（iii）为下一代的数码-该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The research goal of this project is to design a comprehensive methodology for cybersecurity monitoring and mitigation of the electric power distribution system with a multitude of dynamical devices that are prone to cyberattacks as well as power electronically interfaced renewable generation units. The power electronics interfaces complicate the control and operation of the distribution system because of their sensitivity to undesired disturbances. By promoting a more secure power system, this work helps increase the resiliency of the distribution system to extreme events, which is in line with the U.S. national priorities. Moreover, this work promotes teaching and learning by (i) educating and training graduate students through several programs including a week-long practicum hosted at an industry site; (ii) disseminating the results of our work via conference presentations and publications; and (iii) introducing significant updates in the syllabi of two courses. This work also increases participation of underrepresented minorities via active recruitment. The overarching research goal of this project is to design a comprehensive methodology for cybersecurity monitoring and mitigation in systems with a multitude of dynamical devices that are prone to cyberattacks. To demonstrate the performance of our proposed algorithms, we study their application for an electric power distribution system as a critical cyberinfrastructure, which includes substations, feeder devices, and smart meters. The electric power grid's growing dependency on information and communication technology (ICT) significantly increases its vulnerability to cyber attacks. A major area of concern is the security of supervisory control and data acquisition (SCADA) systems that the power grids rely upon for monitoring and control functions. To address these challenges, our specific objectives are (i) detection of cyberthreats on the distribution system, (ii) mitigation of and response to cyberintrusions especially with power electronically interfaced renewables via multiagent-based algorithms as well as trajectory shaping and frequency regulation strategies, and (iii) preparing the next generation of cyber-aware engineers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
