摘要
综合能源系统是在智能电网的基础上,引入热动系统、热力网、燃料管网等非电能源载体,多种能源综合分配、互补利用,涵盖多种能源发/输/储/用的综合性系统。当前,国内针对综合能源系统重点关注其技术可行性、源–荷匹配、能量运输路径和经济性等因素;技术方面主要考虑多种能源的源与荷在多种可能的运行工况下的匹配、能源系统定工况计算与静态稳定等,尚无系统的开展对综合能源系统设备层级和系统层级的动态特性研究成果。文章从综合能源系统建设需求入手,分析了综合能源动态仿真技术的必要性和迫切性,从系统、模型、计算3个层面梳理了拟开展研究的技术路线和技术难点,亦是开展综合能源系统动态仿真技术研究先期工作的总结,对后续综合能源动态仿真系统的规划与建设有良好的指导意义。
Integrated energy system(IES)is a kind of smart grid-based comprehensive system,combining with thermodynamic system,heat supply network,fuel network etc,which covers different links(e.g.production,transmission,storage and utilization)of a wide range of energies.At present,specific to IES,the aspects of technical feasibility,source-load balance,transmission path and economical efficiency are the focus.Technically,the source-load balance under different operation modes,steady condition calculation and static stability for IES are mainly considered.On the contrary,research of dynamic characteristics in device level and system level for IES is still at the starting stage.Based on the construction requirements of IES,this paper analyzes the necessity and urgency of the dynamic simulation technology for IES.Furthermore,technical route and difficulties from the perspective of system,model and calculation are teased,which is a summary of the pre-research work for IES dynamic simulation technology.In a certain degree,it does good to the follow-up programme and development of IES dynamic simulation system.
