摘要
基于能源互联网"三横四纵"的概念框架,该文按能量利用特征将综合能源系统的发展历程划分为孕育、概念、起航和升华4个阶段,并梳理了各阶段对应的关键技术及典型形态,即:1)孕育阶段,以基于能的梯级利用的天然气冷热电联产系统为主;2)概念阶段,以基于能的因地制宜的分布式能源系统为主;3)起航阶段,以基于能的多能互补的综合能源系统为主;4)升华阶段,以基于能的互联互济的能源互联网为主。可看出,综合能源系统是在能源转型驱动下逐渐形成的"冷热电气"多能源供应态势,并在互联网技术下逐渐体现出能的"商品化"共享特征,相关形态的规划、标准以及示范工程也已先行先试。最后,从熵的角度阐释综合能源系统能量流和信息流高度融合的机制,印证泛在能源网成为综合能源系统的未来趋势。
Based on the conceptual framework of"three horizontals and four verticals"in EI(energy internet),the development process of IES(integrated energy system)is divided into four stages in this paper:nurturing stage,conceptual stage,sailing stage and sublimation stage. In each stage the key technologies and typical forms are elaborated. The key technologies are cascade utilization,adaptation to local condition,multi-energy complementary and energy interconnection,respectively. Correspondingly,the typical forms of the above four stages are the combined cooing heating and power system driven by natural gas,distributed energy system,multienergy system and EI,respectively. Thus,IES is a multi-energy suppling situation,which includes cooling,heating,power and gas,and is driven by energy transformation and inter-crossing. Then the"commodification"of the shared energy in IES is gradually embodied under the internet technology. Meanwhile,the related programs,standards and demonstration projects of IES are coming into an advance trial phase. Finally,from the viewpoint of entropy,the development mechanism of IES is elaborated,where energy flow and information flow will be integrated profoundly and extensively. Namely,ubiquitous energy system has become the development direction of IES.
