关于能源互联网层次架构的思考

能源利用系统包括一次能源通过载能介质的转换传输最终在工业、建筑物、交通运输三个领域以电、热和运输驱动力三种方式得以终端利用，是能源利用全过程的普遍规律。未来以可再生能源为主时代，能源互联网EI以智能电网、智能天然气管网为骨架，联结千万个基本单元—分布式供能系统DES，在高、低端储能辅助下实现高效转换和供需平衡。EI中的所有网络和单元都须先明晰其物理架构、流结构和功能层次结构等，才能建立表现为计算机软件的模型，并借助于互联网、大数据、云计算和人工智能实现规划、调度、管理和交易的优化，实现实时平衡和安全保障。

Cogitating About the Hierarchy of Energy Internet

Energy Utilization System includes energy transformation & transportation subsystem via certain media; energy utilization subsystem, which includes three areas: industry, architecture & transportation. The three energy finally terminal use forms are: electricity, heat and movement driving force. This is the general law of total energy utilization process. At the renewable energy era, the Smart Grid (SG) & Smart Natural Gas Grid (SNG), as the core bone structure of Energy Internet (EI), will connect thousands of basic units—Distributed Energy Systems (DES), realizing high-efficient transformation and the balance between supplying and demanding aspects, by means of Energy Storage Infrastructures on both top and bottom sides. It is necessary to clearly describe the Physical Hierarchy, Flux Structure and Function/Hierarchy Structure of all sub networks and units inside EI at first. Then it is possible to model and optimize them at all the level of planning, operating, controlling, management and marketing; realizing time-reliant balance and security guarantee by means of Internet, Big Data, Cloud Computation, and Artificial Intelligent.
