城市能源互联网初步认识与研究展望

摘要

城市能源互联网(UEI)可以买现城市区域内风、光、冷、热、电、气、储多种能源的高效转换和电力网络、天然气网络、电气化交通网络等多种网络的深度融合.结合多方观点,给出了UEI的概念;从规划、运行和运营的角度分析了UEI的建设将对当前电力系统造成的影响,并概述相关方面的研究动态;提出了包含元器件建模技术、综合规划技术、协调优化控制技术、运营技术在内的UET关键技术体系,并从设备形态、系统规划、运行控制、商业模式和协同发展5个方面对UEI的发展和研究进行展望.%UEI(Urban Energy Internet) can be used to realize the efficient conversion among multiple energy sources within urban area,such as wind,solar,cooling,thermal,electric,gas,storage,etc.,and the deep integration of multiple networks,such as electric power,gas,electrified transportation,etc.A UEI concept integrating different viewpoints is given,the effects of UEI development on the power system are analyzed in the aspects of planning,operating and marketing,the research trends of UEI are summarized,a key technology system of UEI is proposed,including component modelling,comprehensive planning,coordinated optimal control and operation,and the development and research prospect of UEI is discussed in the aspects of equipment morphology,system planning,operational control,commercial mode and coordinated development.
