具有智能外围的智能电网——能源互联网架构
Smart Grids with Intelligent Periphery: An Architecture for the Energy Internet
未来的智能电网应能够实现能源互联网的愿景:数百万用户利用可再生能源,在家庭、办公室和工厂生产所需的能源,并实现共享;广泛使用电动车辆和本地储能系统;利用互联网技术将当前电网升级为实现能源共享的互联网络。为实现这个愿景,本文提出了具有智能外围的智能电网的架构和概念,或称为智能GRIP。GRIP架构的构建模块被称为集群,配置能量管理系统(EMS) 的输电网是一个在电网核心的集群,外围的配电网,微电网和智能楼宇及住宅均为(外围的) 集群。这些集群全部采用分层结构。GRIP的分层架构可让电网实现从当前电网功能到未来即插即用型电网的无缝过渡。所有的集群都包括三个基本功能,即调度、消除波动和故障缓解。为实现上述功能,本文提出了风险约束的调度方法;开发了一种名为'电力弹簧'的新型装置,用于消除外围集群的电力波动;另外还讨论了故障的缓解措施。
A future smart grid must fulfill the vision of the Energy Internet in which millions of people produce their own energy from renewables in their homes, offices, and factories and share it with each other. Electric vehicles and local energy storage will be widely deployed. Internet technology will be utilized to transform the power grid into an energy-sharing inter-grid. To prepare for the future, a smart grid with intelligent periphery, or smart GRIP, is proposed. The building blocks of GRIP architecture are called clusters and include an energy-management system (EMS)-controlled transmission grid in the core and distribution grids, micro-grids, and smart buildings and homes on the periphery; all of which are hierarchically structured. The layered architecture of GRIP allows a seamless transition from the present to the future and plug-and-play interoperability. The basic functions of a cluster consist of ① dispatch, ② smoothing, and ③ mitigation. A risk-limiting dispatch methodology is presented; a new device, called the electric spring, is developed for smoothing out fluctuations in periphery clusters; and means to mitigate failures are discussed.
