中文摘要：

构建以融合可再生能源与互联网信息技术为特征的能源互联网,建立从集中利用传统化石能源向清洁能源转变的能源利用体系将是实现能源结构绿色化和用能高效化的根本途径。基于此背景下,首先介绍了国内外能源互联网的研究现状,指出能源互联网是以电能为主体形式、以智能电网为载体的能源互联网络,进而对能源互联网的体系架构进行研究;其次,对电力、交通、天然气等网络的融合现状进行分析,指出研究电网和电气化交通网的协调规划、考虑计及各类不确定性因素的天然气网和电网协调规划、热-电联合系统等方面将是能源互联网的研究重点;最后分析了发展能源互联网中的关键技术,并指出后续关键技术研究中的突破方向。

英文摘要：

The study of building energy internet, which is featured by integration of renewable energy and internet information technology, will be the fundamental way to forge a green energy structure and improve energy efficiency. Firstly,this paper introduces the general research of energy internet at home and abroad, and indicates that electricity is the major energy form of energy internet and the smart grid is the carrier. Based on that, the system architecture of energy internet is studied. Secondly, the situation of sophisticated network system that includes power network, transportation system and natural gas network is analyzed; coordinated planning of electrified transportation system and power network, coordinated planning of gas and power network considering various uncertain factors, combined heat and power network are proposed as the research emphases of energy internet. Finally, key technologies of energy internet are analyzed and future research directions are pointed out.
