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.

能源基础设施是现代社会的重要支柱，其安全可靠的运行受到任何损害或破坏，都会对人们的日常生活和国民经济产生突出影响。该项目开发了一个硬件在环可重构系统，具有嵌入的智能和弹性协调方案，将解决电网的脆弱性。这一系统在以下关键方面有别于以往和现有的研究工作。首先，它在系统设计中利用并整合了新的电力电子技术，以便于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较低水平，使本地设备具有做出决策的能力，并对突发事件做出更快的反应。第三，它采用控制理论的实时自适应策略，分析保证对不可预测的系统变化提供期望的动态响应，从而有效地维护大型分布式系统的可用性。最后，不仅通过仿真对系统进行了评估，还在微电网试验台上进行了实现和演示。评估从实时响应能力、故障恢复能力、本地协作能力三个方面进行。电网是一个由高度相互作用的子系统组成的复杂网络的典型例子。解决这些根本性问题，以建立一个有弹性的电网，对这一基础设施和其他关键基础设施具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，包括创新的多大学课程设计，积极从现有方案支持的代表性不足的群体中招收学生，以及广泛传播研究成果。
