Key Technologies for Building Highly Resilient Urban Energy Systems

城市能源系统结构复杂且脆弱,容易受到极端事件的影响,“高弹性”成为城市能源系统建设新目标。首先,剖析高弹性城市能源系统建设面临的“结构脆弱环境恶化协调不足恢复复杂”四大难题,明确高弹性城市能源系统的研究边界,分析“弹性城市”面临的自然灾害、环境恶化、人为干预三类威胁,总结能源结构优化带来风险、多能流网架协调复杂和信息物理通信安全存在威胁的三个典型特征;其次,按照“物理信息应用”三个层面提出建设高弹性城市能源系统的九类关键技术,分别阐述各类技术的发展现状,讨论其主要特征;最后,从物理层、信息层和应用层分别对高弹性城市能源系统的未来研究与发展路径进行了展望,为逐步建立智慧能源网络、智能控制系统以及安全供需体系,完善城市能源风险应急管控措施,加强城市能源供应保障,强化重要能源设施,增强能源网络安全防护提出建议。

Because of the complex and fragile structures of urban energy systems,which are easily affected by extreme events,constructing highly resilient systems has become a new area of focus.First,we analyze the four major problems of“structural vulnerability,environmental degradation,inadequate coordination,and complex recovery”facing the construction of highly resilient urban energy systems;clarify the research boundary of such energy systems;analyze the threats of natural disasters,environmental degradation,and human intervention faced by“resilient cities”;and summarize the risks associated with energy structure optimization and the complex coordination of multi-stream grids.Secondly,we propose nine key technologies for building highly resilient urban energy systems at three levels of“physical-informationapplication”and discuss the development status and main features of each technology.Finally,future research and development paths for highly resilient urban energy systems are proposed in the physical,information,and application layers,and suggestions are made to gradually establish intelligent energy networks,intelligent control systems,and security supply and demand systems and to improve urban energy risk emergency control measures,strengthen urban energy supply assurance,enhance important energy facilities,and strengthen energy network security protection.
