摘　　要：在“双碳”背景下,城市发展必然需要考虑到自身用能结构的变化。城市用能需求十分复杂,而新型的综合能源系统通过将电力、燃气、制冷等系统因地制宜地规划与统一协调分配,在保证城市经济生活平稳运行的前提下,可提高整个系统供能的灵活程度,从而提高能效、降低碳排放。简要介绍综合能源系统技术,对广州市某重点商业区域未来规划的综合能源系统进行综合效益分析。经估算,集中供冷可实现年转移尖峰电量2670万kW·h,节约标煤约8758t/a,减少二氧化碳排放约2.7万t/a。基于区域特点,探索建设天然气三联供系统、分散式储能、光伏等多种能源设施,发挥多能互补、节能安全、灵活的作用。在项目建设运营管理方面,与区域规划的衔接、稳定的签约供冷用户和完善的用户侧管理标准规范,可为项目后续稳定运行提供有效保障。In the context of"dual carbon",urban development must take into account the changes of its own energy consumption structure.The demand of urban energy consumption is very complex,and through the planning and unified coordination and distribution of electricity,gas,central cooling and other systems based on local conditions,the new integrated energy system can improve the flexibility of the energy supply of the entire system while ensuring the smooth operation of urban economic life,so as to improve energy efficiency and reduce carbon emissions.This article briefly introduces integrated energy system technology and conducts the comprehensive benefit analysis of the future planned integrated energy system in a key commercial area in Guangzhou.It is estimated that central cooling can transfer peak power by 267,000,000 kW·h per year,save standard coal by about 8,758 t/a and reduce carbon dioxide emission by about 27,000 t/a.Based on regional characteristics,this paper explores the construction of the natural gas trigeneration system,decentralized energy storage,photovoltaics and other energy facilities to give play to the roles of multi-energy complementarity,energy-saving safety and flexibility.In terms of the construction and operation management of the project, the convergence with regional planning, stable contractedcooling users and perfect user-side management standards and specifications can provide an effective guarantee forthe subsequent stable operation of the project.
