简单来说,城市能源互联网是以电为中心的城市各类能源互联互通、综合利用、优化共享的平台。城市能源互联网建设是以智能电网为基础,以“互联网+”为手段,以电能为主体载体的绿色低碳、安全高效的现代能源生态系统

近日,国家能源局公布首批55个“互联网+”智慧能源(能源互联网)示范项目,包括北京延庆能源互联网综合示范区、崇明能源互联网综合示范项目等在内的12个城市能源互联网综合示范项目,并要求于2017年8月底前开工,于2018年底前建成。这意味着一个能源清洁、高效利用的城市发展时期即将到来。

城市是能源消费主体

能源是城市正常运转不可或缺的要素,全世界80%的能源消耗集中在城市

能源是一座城市正常运转不可或缺的要素,城市也是能源消费的主体,全世界80%的能源消耗集中在城市。随着经济发展和城镇化的加速,城市能源需求不断增长,然而城市能源资源却极为有限,除部分可再生能源外,其他能源基本靠外送。同时,化石能源的大范围使用,给城市带来了严重的污染问题。

“我国已成为全球能源第一消费大国,但目前探明的能源资源储量十分有限,随着各地城镇化及工业化进程加快,能源需求缺口将进一步扩大。加之我国能源富集区域与负荷中心的逆向分布,导致能源供给与需求无法高效匹配,可持续发展局面堪忧。此外,雾霾问题已成为近年来我国大气污染的突出标志。”国家电网四川省电力公司副总经理褚艳芳表示,努力提高全国各地能源基础设施的承载能力和运行效率,加快推进城市用能习惯转变,实现清洁能源替代和能源综合优化配置,建设城市能源互联网势在必行。

构建城市能源互联网也是保障我国经济与社会发展的需要。以成都为例,预计到“十三五”时期末,成都市全社会用电量将达到658亿千瓦时,年均增长6.20%。“由于资源禀赋所限,成都市自身拥有资源有限,因此必须以城市能源互联网为根基,带动能源大规模送入,实现成都市各区(市)县能源优化配置,保障成都市电力供应需求。”褚艳芳说。
