Distributed Converter Modules: Design, Configurations, Aggregated Modeling, and Control

纳米电网是一种非常小规模的配电系统，其包含用于一组分布式负载和资源的能量管理和功率转换器系统。智能纳米电网可以小到几个光伏电池板或电池储能系统，为小负载供电，也可以大到几个住宅或商业建筑。这项研究的重点是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的设计，建模和开发，特别适用于纳米网格应用。拟议的概念和原型将进行实验测试，为真实的生活条件和工业法规，使用我们的CFI资助的实验室开发工业级能源系统拓扑结构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，使纳米网格成为一个模块化和即插即用的系统，促进系统的逐步扩展与需求和负担能力成正比。将探索新型分布式配置，以互连可再生能源、储能、分布式负载和电网的模块化功率转换器。系统配置以及新颖的分布式控制系统确保了独立、并网、并联或并网模式下的无缝运行。分布式转换器和控制系统的聚合建模将被导出，以保证系统级的稳定性和最佳的能量管理，最小的通信带宽，使纳米网格对技术人员的依赖最小化，以构建，扩展和维护。 这种模块化可再生纳米网格特别有利于预算有限的人或偏远和北方原住民社区。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有助于支持电网。这种优化的纳米网格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，以及更智能的能源存储，使用或生产。拟议的研究计划将帮助加拿大实现这些目标，并有助于政府加快创建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.
