EAGER: US Ignite: Enabling Highly Resilient and Efficient Microgrids through Ultra-Fast Programmable Networks

提高配电控制基础设施的弹性，不仅可以降低电网对极端事件的脆弱性，而且可以促进绿色或可再生能源的使用，是一个迫切需要解决的问题。在不同的选择中，微电网是一个新兴的、有前途的范例。微电网是一种小型网络，旨在为小型社区（例如购物中心，工业园区或大学校园）提供电力和热负荷。它通常包含一组由中央控制器控制的分布式发电机、负载、存储和保护装置。对于主电网来说，微电网是一个单一的实体，既可以为大电网发电，也可以消耗电力。这极大地简化了微电网和主电网之间的相互作用，允许在微电网领域内轻松引入和快速发展新形式的异构技术的计算机控制。然而，具有重要可再生能源组成部分的微电网在发电方面可能会经历快速变化。在这些波动期间实现快速的电压和频率控制是极其重要的，否则系统可能在负载和发电之间失去平衡，并可能最终崩溃。微电网的控制依赖于快速、可靠的通信；在最严格的情况下，消息必须在几毫秒内传递。该项目将软件定义网络（SDN）技术与微电网控制相结合，以稳定和优化系统运行。该项目将在康涅狄格大学迪堡校区的一个微电网上演示这些技术。对于该项目，SDN技术将有三种一般用途：路由重新配置以避免网络性能问题并提高网络可靠性，数据包优先级以提供服务质量（QoS）以支持低延迟交付，以及监控与微电网控制相关的数据流。该项目将采用两阶段的方法进行演示和评估，并与康涅狄格州立大学设施运营部门和微电网承包商施耐德电气密切合作。在第一阶段，它将使用一个虚拟的硬件在环环境，接收来自微电网的实时测量，并密切模仿实际的微电网状态。具体来说，环境将包含真实的通信基础设施和（小规模）能源和负载，而系统的其余部分将通过跟踪驱动的模拟，使用来自运行微电网的实时测量。一旦第一阶段演示和评估了技术，项目负责人将与施耐德电气和UCONN设施运营部门合作，将开发的技术纳入更大的分期设施，以进一步评估和改进，并可能被Depot微电网采用。

Improving the resilience of the electric distribution control infrastructure is an urgent issue not only to reduce the vulnerability of the power grid to extreme events but also to facilitate the use of green or renewable energy. Among different options, microgrids are an emerging and promising paradigm. A microgrid is a small-scale network designed to supply electrical and heat load of a small community (e.g., a shopping center, an industrial park, or a university campus). It typically contains a set of distributed generators, load, storage and protection devices that are controlled by a central controller. To the main power grid, a microgrid is a single entity that may either produce power for the larger grid or consume power. This dramatically simplifies the interaction between a microgrid and the main grid, allowing for the easy introduction and rapid evolution of new forms of computer control of heterogeneous technologies within the micro-grid domain. However, microgrids with a significant renewable energy component may experience rapid changes in power generation. It is extremely important to achieve fast voltage and frequency control during these swings otherwise the system may lose balance between load and generation and may eventually collapse. Control of microgrids relies on fast, reliable communications; in the most stringent cases messages must be delivered within a few milliseconds. This project will integrate Software Defined Networking (SDN) technology with microgrid control to stabilize and optimize system operation. The project will demonstrate the techniques on a microgrid at the University of Connecticut Depot Campus.For this project SDN technology will have three general uses: route reconfiguration to avoid network performance issues and improve network reliability, packet prioritization to provide Quality of Service (QoS) in support of low latency delivery, and monitoring of data flows associated with microgrid control. The project will use a two phase approach to demonstration and evaluation both in close collaboration with UCONN Facilities Operations and Schneider Electric, the microgrid contractor. In the first phase it will use a virtual hardware-in-the-loop environment that receives real-time measurements from the microgrid and closely mimics the actual microgrid status. Specifically, the environment will contain real communication infrastructure and (small-scale) energy sources and load, while the rest of the system will be through trace-driven simulation using real-time measurements fed from the operational microgrid. Once the first phase has demonstrated and evaluated the techniques the PIs will work with Schneider Electric and UCONN Facilities Operations to incorporate the developed techniques into a larger staging facility for further evaluation and refinement and possible adoption by the Depot microgrid.
