Collaborative Research: CT-T: A Resilient Real-Time System for a Secure and Reconfigurable Power Grid

能源基础设施是现代社会的重要支柱，对其安全可靠运行的任何损害或破坏都将对人们的日常生活和国民经济产生重大影响。该项目开发了一种硬件在环可重构系统，具有嵌入式智能和弹性协调方案，可以解决电网的脆弱性。该系统在以下几个关键方面与以往和现有的研究成果有所不同。首先，它在系统设计中利用并集成了新的电力电子技术，以促进更直接地重新配置电网的物理组成。其次，它将智能推向电网的底层，这样本地设备就有能力做出决定，并对突发事件做出更快的反应。第三，采用控制理论实时自适应策略，分析保证对不可预测的系统变化提供期望的动态响应，有效维护大型分布式系统的可用性。最后，通过仿真对系统进行了评估，并在微电网试验台上进行了实现和验证。从实时责任、故障恢复能力、局部协作能力三个方面进行评价。电网是由高度相互作用的子系统组成的复杂网络的典型例子。解决这些基本问题，以创建一个有弹性的电网，对这个和其他关键基础设施有直接和直接的影响。该项目与强大的教育组成部分相结合，包括创新的多所大学课程设计，在现有项目的支持下，从代表性不足的群体中积极招募学生，以及广泛传播研究成果。

Energy infrastructure is a critical underpinning of modern society that any compromise or sabotage of its secure and reliable operation will have a prominent impact on people's daily lives and the national economy. This project develops a hardware-in-the-loop reconfigurable system with embedded intelligence and resilient coordination schemes that would tackle the vulnerabilities of the power grid. This system differentiates itself from previous and existing research efforts in the following key aspects. First, it capitalizes and integrates new power electronic technologies in the system design to facilitate a more direct reconfiguration of the physical makeup of the grid. Second, it pushes the intelligence toward the lower level of the power grid such that local devices have the capability to make decisions and to react more quickly to contingencies. Third, it adopts control-theoretic real-time adaptation strategies for analytic assurance on providing desired dynamic responses to unpredictable system changes to efficiently maintain the availability of large distributed systems. Finally, the system is evaluated not only through simulation, it is also implemented and demonstrated on a microgrid testbed. The evaluation is conducted from three aspects, including real-time responsibility, fault resiliency, local collaboration capability. The power grid is a typical example of complex networks of highly interacting subsystems. Solving these fundamental problems to create a resilient power grid has a direct and immediate impact on this and other critical infrastructure. The project is coupled with a strong educational component including an innovative multi-university curriculum design, active recruitment of students from underrepresented groups supported by existing programs, and broad dissemination of research findings.
