MRI: Development of Grid of Nanogrids (GNG) Testbed

人工智能和物联网的最新进展将深刻影响未来的基础设施。人们可以想象一个拥有互联交通、公用事业和智能建筑的智能城市。每个组件将能够独立工作，并能够抵御物理和网络攻击。智能建筑可以被认为是一个能够形成更大网络的纳米网格。基于网格的网络的潜力已成为国家优先考虑的问题，并引起了工业界和学术界许多专家的注意。该项目将开发一个混合和模块化的测试平台，代表网格形成的智能建筑。仪器开发将是堪萨斯州立大学电气和计算机工程以及计算机科学系之间的合作。虽然试验台是为研究未来城市的电力基础设施而设计的，但它可以重新配置用于其他应用，如测试船舶和新兴的机载电力推进系统。因此，它可以适用于广泛的新兴应用程序和测试场景。pi将开发一门关于现代配电系统的网络安全和弹性的新课程。测试平台的广泛可用性，加上相关的课程，将吸引来自代表性不足的社区的学生。提议的测试平台提供了在所有可能设想的配电网运行条件下，包括孤岛和网络模式下的故障和异常，检查纳米电网控制、硬件、软件、通信和安全协议以及标准的各种假设和研究想法的能力。“纳米电网”测试平台具有高度可扩展、模块化和可重构的架构，包括一个实时模拟器平台，用于创建由本地和远程用户设计的定制电网，一个单相馈线纳米电网，一个硬件实现的三相纳米电网，一个模块化自学习逆变器，以及扩展硬件在环纳米电网数量的能力。拟议的测试平台将立即使pi及其合作者能够推进他们在电网网络安全、能源管理、监督控制和态势感知等领域的研究议程。该试验台旨在支持外部研究人员的远程访问，以促进智能建筑和智能城市电网设计和实施的当前工作。该奖项反映了美国国家科学基金会的法定使命，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。

Recent advancements in artificial intelligence and the internet of things will impact future infrastructure profoundly. One can imagine a smart city with interconnected transportation, utilities and smart buildings. Each component would be capable of working independently and able to resist physical and cyber-attacks. Smart buildings can be considered as a grid of nanogrids capable of forming a larger network. The potential of grid-based networks has become a national priority and attracted the attention of many experts in both industry and academia. This project will develop a hybrid and modular testbed that represents grid-forming smart buildings. Instrumentation development will be a collaborative effort between the electrical and computer engineering and computer science departments at Kansas State University. Although the testbed is designed for research on electricity infrastructure for future cities, it could be reconfigured for other applications such as testing marine and emerging airborne electrical propulsion systems. Hence, it can be applicable to a wide range of emerging applications and test scenarios. The PIs will develop a new course on cybersecurity and resiliency of modern power distribution systems. The wide availability of the testbed, coupled with related coursework, will attract students from underrepresented communities.The proposed testbed provides the capability to examine various hypotheses and research ideas on nanogrid controls, hardware, software, communications and security protocols, and standards, under all possible envisioned operating conditions of the power distribution grid, including faults and anomalies in both islanded and networked modes. The "Grid of Nanogrids" testbed features a highly scalable, modular, and reconfigurable architecture consisting of a real-time simulator platform for creating customized power networks designed by local and remote users, a single-phase feeder nanogrid, a three-phase nanogrid implemented in hardware, a modular self-learning inverter, and the capability of extending the number of hardware-in-the-loop nanogrids. The proposed testbed will immediately enable the PIs and their collaborators to advance their research agendas in fields such as power grid cybersecurity, energy management, supervisory control, and situational awareness. The testbed will be designed to support remote access for outside researchers to facilitate advancing current work in the design and implementation of smart buildings and power networks for smart cities.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.
