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，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块光伏电池板或电池储能系统提供小负载，也可以大到几栋住宅或商业建筑。这项研究的重点是设计、建模和开发专门适用于纳米栅格应用的分布式高功率密度转换器的拓扑结构、体系结构、控制系统和能量管理策略。建议的概念和原型将使用CFI资助的实验室，针对实际生活条件和行业法规进行实验测试，以开发用于智能纳米电网系统的工业级能源系统拓扑和控制解决方案。研究计划的目标之一是设计新的智能拓扑和配置，使纳米格栅成为模块化和即插即用的系统，促进系统的逐步扩展，使其与需求和负担能力成比例。将探索新的分布式配置，以互连用于可再生能源、能量存储、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在独立、并网、并行或并网模式下无缝运行。分布式转换器和控制系统的聚合建模将保证系统级的稳定性和以最小的通信带宽进行最优的能量管理，从而使纳米格栅对技术人员的构建、扩展和维护的依赖性最小。这种模块化的可再生纳米格栅特别有利于预算有限的人或偏远和北部的原住民社区。与现有的可再生分布式发电系统不同，这项技术在大规模住宅应用中的使用也将有助于电网的支持。这种优化的纳米格栅能源解决方案将提高整体效率、成本、尺寸和可靠性，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，并使加拿大成为高效可再生纳米格栅和基于电力电子的能源系统解决方案的市场领先者。

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.
