地下空间支撑下的城市轨道交通和能源系统融合发展研究

Integrated Development of Urban Rail Transit and Energy Systems Supported by Underground Space

城市因人口、经济活动高度集中而产生极大的能源消耗量,也是各类风险高度集聚的重点区域;能源和交通作为城市碳减排的重点领域、城市“生命线”工程的重要组成部分,进行融合发展对于城市绿色低碳、安全韧性建设具有重要价值。本文梳理了城市轨道交通与能源领域的低碳韧性发展现状,涵盖城市轨道交通低碳发展、城市轨道交通与能源系统韧性评估及提升、储能系统安全防控及风险评估三方面;提出了地下空间支撑下的城市轨道交通多能源融合系统构想,阐述了常态时期、极端条件下相应系统的运行模式;从环境、经济、社会角度分析了城市轨道交通多能源融合系统的潜在效益,展望了构想系统的未来研究方向与可能的解决思路。研究建议,完善城市轨道交通多能源融合系统政策机制,推进多部门协同治理;构建城市轨道交通多能源融合系统科技创新体系,助力实现城市轨道交通低碳、安全、高效运行;推动城市电网和轨道交通协同管理体系建设,增强城市“生命线”工程韧性治理能力。

Cities consume a large amount of energies owing to their high population density and centralized economy,and have high concentration of various risks.Energy and transportation are key areas for carbon emission reduction in urban areas and significant components of urban lifeline engineering.Therefore,the integrated development of energy and transportation systems is crucial for the low-carbon and resilient construction of cities.This study first reviews the low-carbon and resilient development status of urban rail transit and energy systems,covering three aspects:low-carbon development of urban rail transit,resilience assessment and improvement,and security protection and risk assessment of energy storage systems.Moreover,the concept of an underground-spacesupported multi-energy-integrated urban rail transit system is proposed,elaborating the operating modes of the system in normal times and extreme conditions.Subsequently,benefits of the proposed system are analyzed from the perspectives of environment,economy,and society,and future research directions and key problems to be solved are introduced.Furthermore,the following suggestions are proposed:(1)improving the policy mechanism for the multi-energy-integrated urban rail transit system and promoting coordinated governance by multiple departments,(2)constructing a technology innovation system for the system to realize low-carbon,safe,and efficient operation of urban rail transit,and(3)promoting the development of a coordinated management system for urban power grids and rail transit to enhance urban resilience.
