摘　　要：天然气是我国碳中和行动中与零碳能源相伴的重要低碳能源,而燃气分布式能源是最高效的天然气应用技术,在碳达峰阶段有着重要的减碳作用。对基于区域能源中心的燃气分布式供能系统运行数据进行分析,验证与传统能源系统相比的节能减碳效果。结论表明,在区域能源冷热电运行中年度节能率可达14%,按上海电网电力排放因子测算年度减排CO_(2)7%以上。研究认为在区域能源中心,分布式能源系统通过运行优化可进一步提高节能减碳的能力,主要措施为加强运行管理,降低系统自耗电、调整供热模式并采取储热系统实现夏季供热负荷平衡和转移以提高供热占比。为此,提出运行优化和控制策略,为今后同类型项目提供指导和借鉴。Natural gas is an important low-carbon energy that accompanies zero carbon energy in Chi-na's carbon neutrality action,and gas distributed energy is the most efficient natural gas application technology,playing an important role in reducing carbon during the carbon peak stage.In this paper,the operation data of the gas distributed energy supply system based on regional energy center is ana-lyzed to verify the energy-saving and carbon reduction effect compared with the traditional energy sys-tem.The conclusion indicates that the annual energy saving rate in regional energy cooling,heating and power operation can reach 14%,and the annual CO_(2)emission reduction is calculated to be over 7%based on the Shanghai power grid power emission factor.Research suggests that in regional ener-gy centers,distributed energy systems can further improve their energy conservation and carbon re-duction capabilities through operational optimization,the main measures are to strengthen operational management,reduce system self-consumption,adjust the heating mode,and adopt a heat storage system to achieve summer heating load balance and transfer to increase the proportion of heating.To this end,operational optimization and control strategies are proposed to provide guidance and refer-ence for similar projects in the future.
