项目摘要

Power electronics are the key building blocks of future energy systems. Power electronics play critical roles in renewable energy integration, computing and telecommunication, grid-scale energy storage, and transportation electrification, all at the edge of the future smart grid. These emerging energy systems are usually modular and granular. This research project targets a generalized design method that will enable a new family of power electronics that can achieve high performance and perform new functions at the grid edge for a variety of applications. ``Granular power electronics'' represents a systematic design approach that pushes the intelligence and capability of power electronics to a granular level that has not been demonstrated before. The PI will leverage the recent advances in wide-band-gap devices, circuit architectures, and control methodologies to address the challenges of controlling sophisticated power flow, modeling magnetics with granular structures, and addressing the inverter-to-inverter oscillation problem in nano-grids with many smart inverters. The results of this project will be incorporated into the efforts that the PI is currently leading as a part of the "Campus-as-a-Lab" program to create research opportunities for undergraduate students. The outreach program for K-12 students, involving them in the development of experimental demos, will expose them to the role of power electronics in improving the quality and sustainability of our daily lives and attract them to pursue STEM careers.The PI will perform a systematic investigation on the fundamental principles of granular and modular power electronics. The PI will (1) develop design toolkits (modules, schematics, and layout patterns) comprising switched-inductor cells, switched-capacitor cells, bridge structures, and magnetic-couplers which may serve as the basis of granular power conversion architectures, (2) establish systematic methods to evaluate the topology, select the components, control the power flow, model the magnetics, estimate the grid impedance, and perform stability analysis of granular power electronics and systems with sophisticated power flow; (3) develop open-source computer-aided-design tools for the design and control of granular power conversion architectures; and (4) build small-scale experimental systems to verify the developed methods and benefit education. The PI will use three emerging and important energy systems at the grid edge as examples - smart inverters (distributed energy generation), large scale energy systems (data center power delivery), and a nano-grid test platform for multidisciplinary energy systems research. High performance grid-interface power electronics topologies will be studied, and model-based multi-agent control strategies will be developed to enable a future smart grid with many granular power electronics at the edge.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.

电力电子设备是未来能源系统的关键构建模块。电力电子在可再生能源集成、计算和电信、电网规模储能和交通电气化等领域发挥着关键作用，所有这些都处于未来智能电网的边缘。这些新兴能源系统通常是模块化和细粒度的。该研究项目的目标是一种通用的设计方法，该方法将使新的电力电子产品系列能够实现高性能并在电网边缘为各种应用执行新功能。 “粒度电力电子技术”代表了一种系统设计方法，可将电力电子技术的智能和功能提升到前所未有的粒度水平。 PI将利用宽带隙器件、电路架构和控制方法方面的最新进展来解决控制复杂功率流、用粒状结构建模磁性以及解决纳米级逆变器到逆变器振荡问题的挑战。具有许多智能逆变器的电网。该项目的成果将纳入 PI 目前领导的“校园即实验室”计划的一部分，为本科生创造研究机会。针对 K-12 学生的外展计划，让他们参与实验演示的开发，将使他们了解电力电子在提高我们日常生活的质量和可持续性方面的作用，并吸引他们从事 STEM 职业。PI 将执行对颗粒和模块化电力电子设备基本原理的系统研究。 PI 将 (1) 开发设计工具包（模块、原理图和布局图案），其中包括开关电感器单元、开关电容器单元、桥结构和磁耦合器，可作为粒度功率转换架构的基础，（2 ) 建立系统方法来评估拓扑、选择组件、控制功率流、磁学建模、估计电网阻抗，并对具有复杂功率流的颗粒电力电子设备和系统进行稳定性分析； (3) 开发开源计算机辅助设计工具，用于细粒度功率转换架构的设计和控制； (4)建立小规模实验系统来验证所开发的方法并有益于教育。该PI将以电网边缘的三个新兴且重要的能源系统为例——智能逆变器（分布式能源发电）、大规模能源系统（数据中心电力输送）以及用于多学科能源系统研究的纳米电网测试平台。将研究高性能电网接口电力电子拓扑，并开发基于模型的多智能体控制策略，以实现在边缘具有许多颗粒电力电子的未来智能电网。该奖项反映了 NSF 的法定使命，并被认为是值得的通过使用基金会的智力优势和更广泛的影响审查标准进行评估来获得支持。
