Firstly, the definition of urban internet is given, and the core idea and basic features of urban energy Internet are expounded. Then, the development status and challenges of energy internet are summarized and analyzed from the perspective of operation, planning and marketing. Then, according to the technical characteristics of urban energy internet interconnection, the urban energy internet technical framework of transport layer, information layer, and price layer is proposed, and future development direction of related technologies such as planning, operation, marketing and information involved in the technical framework is analyzed. Finally, according to the characteristics of the terminal energy network in Xiamen city, Fujian Province, urban energy Internet is partially planned and piloted, which provides a blueprint for the comprehensive promotion of the urban energy internet.

0 引言 近年来,我国城镇化进程不断加快,城市已经 逐渐成为了能源消费的主要场所.2016 年,我国城 市能源消费量占全国能源消费总量比例已超过 80%[1] .然而,城市中电、气、热等各个能源子系 统相互独立的供能模式和粗放的能源利用方式极大 地制约了城市能源系统的发展,其面临着能源供应 结构不合理、能源综合利用效率低、可再生能源消 基金项目:国家高技术研究发展计划(863 计划)项目资助 (2014AA051901) 纳能力不足等问题.因此,为了能够实现多种能源 互补共济与高效利用, 提高供能的可靠性和经济性, 能源互联网技术应运而生[2-4] .2011 年美国学者杰 里米・里夫金在在《第三次工业革命》[5] 一书中率 先提出了能源互联网的概念,如今,能源互联网已 经得到了广泛的关注,而城市地区作为区域的用能 中心,在城市地区构建城市能源互联网(Urban Energy Internet, UEI)对于推动城市、国家乃至整个 社会的能源发展都具有积极的意义. 城市能源互联网通过高效的能量耦合设备,实 现多能源系统的互联,通过不同能源形式间的协同 转化提升城市对能源的综合利用效率[6] ;
