纳米电网是一种非常小的配电系统，它包含一个能量管理和功率转换系统，用于一组分布式负载和资源。智能纳米电网可以小到几个提供小负荷的光伏板或电池储能系统，也可以大到几个住宅或商业建筑。本研究的重点是设计、建模和开发分布式高功率密度转换器拓扑结构、架构、控制系统和能源管理策略，特别适合纳米电网的应用。提出的概念和原型将在现实生活条件和工业规范和法规中进行实验测试，使用我们CFI资助的实验室开发工业级能源系统拓扑和智能纳米电网系统的控制解决方案。研究计划的目标之一是设计新颖的智能拓扑结构和配置，使纳米网格成为模块化和即插即用系统，促进系统按需求和可负担性成比例的逐步扩展。将探索新的分布式配置，将可再生能源、储能、分布式负载和电网的模块化电源转换器互连起来。系统配置以及新颖的分布式控制系统确保了在独立，并网，并联或网格形成模式下的无缝操作。将推导分布式变流器和控制系统的聚合建模，以保证系统级的稳定性和以最小的通信带宽进行最佳的能量管理，从而使纳米电网对技术人员的建设、扩展和维护的依赖最小。这种模块化可再生纳米电网特别有利于预算有限的人或偏远和北部的第一民族社区。与现有的可再生DG系统不同，在大规模住宅应用中使用这项技术也将有助于支持电网。这种优化的纳米电网能源解决方案将提高整体效率、成本、尺寸、可靠性，实现更低的碳排放，以及更智能的能源储存、使用或生产。拟议的研究项目将帮助加拿大实现这些目标，并有助于政府加速创造可持续能源解决方案的目标，使加拿大成为高效可再生纳米电网和基于电力电子的能源系统解决方案的市场领导者。

A nano-grid is a very small scale power distribution system that contains an energy management and power converter system for a set of distributed loads and resources. A smart nano-grid can be as small as a few photovoltaic panels or battery energy storage systems supplying small loads, or as large as a few residential or commercial buildings. This research is focused on the design, modeling and development of distributed high power density converter topologies, architectures, control systems, and energy management strategies specifically suitable for nanogrid applications. The proposed concepts and prototypes will be experimentally tested for real life conditions and industrial codes and regulations using our CFI funded labs to develop industrial level energy system topologies and control solutions for smart nano-grid systems. One of the research program objectives is to design novel smart topologies and configurations such that the nanogrid becomes a modular and plug-and-play system facilitating a gradual expansion of the system proportional to the need and affordability. Novel distributed configurations will be explored to interconnect modular power converters for renewable energy resources, energy storage, distributed loads and grid. System configuration as well as novel distributed control systems ensure seamless operations in stand alone, grid connected, parallel or grid forming modes. Aggregated modeling of distributed converters and control systems will be derived to guarantee system level stability and optimum energy management with minimum communication bandwidth, so that the nanogrid have minimum dependency on the technical staff to construct, expand, and maintain. Such modular renewable nanogrids are specifically beneficial to people with limited budgets or remote and northern First Nations communities. Unlike existing renewable DG systems, the use of this technology in large scale residential applications would also contribute to the support of the grid. Such optimized nanogrid energy solutions will improve overall efficiency, cost, size, reliability, enabling lower carbon emissions, and smarter storage, use of, or production of, energy. The proposed research program will help Canada achieve these goals and contribute to the government's objectives of accelerating the creation of sustainable energy solutions and making Canada a market leader in efficient renewable nanogrids and power electronics based energy system solutions.
