项目摘要

Sustainability has become a pressing global challenge. A major means to address this is to utilize renewable energy at a large scale. However, this changes the nature of power systems and imposes unprecedented challenges to the stable operation of a power system, which is arguably the most important infrastructure underpinning social life and economic growth. Following the PI's work on the large-scale utilization of renewable energy, in particular on the synchronized and democratized (SYNDEM) grid architecture and the associated enabling technologies that unifies the interaction of modern power systems, this project aims to solidify its theoretical foundation by developing fundamental systems theory and control algorithms. This will speed up the large-scale utilization of renewable energy, improve the stability, reliability, resiliency of modern power systems, promote energy independence and sustainability, bring job opportunities and economic growth, and eventually lead to a low-carbon economy. This project seamlessly integrates profound multidisciplinary thinking in systems theory, power electronics, and power systems. The port-Hamiltonian systems theory, which combines the historical Hamiltonian modeling approach in geometric mechanics and the port-based network modeling approach in electrical engineering, offers a systematic and scalable mathematical framework for structural modeling, analysis and control of complex networked nonlinear multi-physics systems. This powerful mathematical tool will be further developed to passivate a large-scale, interconnected, geographically distributed, heterogeneous networked power system with millions of power electronic converters and rigorously prove its stability, leading to a uniform mathematical structure for passivated and homogenized modern power systems. The theoretical framework developed will be validated numerically and experimentally. The results will also shed lights on the understanding of other large-scale networked systems. Research results will be disseminated timely worldwide through various channels, including the LinkedIn Group on Virtual Synchronous Machines and Power Electronics-enabled Autonomous Power Systems. Undergraduates and postgraduates from underrepresented groups will be encouraged to take part in the project. The project results will also be included in graduate courses and training programs.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.

可持续性已成为一项紧迫的全球挑战。解决这一问题的主要手段是大规模利用可再生能源。然而，这改变了电力系统的性质，并对电力系统的稳定运行提出了前所未有的挑战，电力系统可以说是支撑社会生活和经济增长的最重要的基础设施。继PI在可再生能源的大规模利用方面的工作之后，特别是在同步和民主化（SYNDEM）电网架构以及统一现代电力系统相互作用的相关使能技术方面，该项目旨在通过开发基本系统理论和控制算法来巩固其理论基础。这将加快可再生能源的大规模利用，提高现代电力系统的稳定性、可靠性和弹性，促进能源独立和可持续性，带来就业机会和经济增长，最终实现低碳经济。该项目无缝集成了系统理论，电力电子和电力系统中深刻的多学科思想。端口-哈密顿系统理论结合了几何力学中的哈密顿建模方法和电气工程中的端口网络建模方法，为复杂网络非线性多物理场系统的结构建模、分析和控制提供了一个系统的、可扩展的数学框架。这个强大的数学工具将进一步发展，以钝化一个大规模的，互联的，地理上分布的，异构的网络电力系统与数以百万计的电力电子转换器，并严格证明其稳定性，导致一个统一的数学结构钝化和均匀化的现代电力系统。理论框架的发展将得到验证的数值和实验。研究结果也将有助于理解其他大规模网络系统。研究成果将通过各种渠道及时在全球范围内传播，包括LinkedIn虚拟同步机和电力电子自主电力系统小组。将鼓励来自代表性不足群体的本科生和研究生参加该项目。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。
