摘要

综合考虑供给侧多种能源供应与需求侧多元能源需求间的逐时匹配与平衡，基于供需耦合分析，构建不同运行工况下天然气分布式热电联产系统CO2减排效果的理论分析模型。数值分析表明，分布式热电联产系统在热电供需均衡点可获得最大减排收益。当需求侧热电比小于均衡热电比时，“以电定热”模式可获得较大的减排效果；反之，“以热定电”模式则是更佳选择。同时，参照系统的选择以及电网供电效率的提升等外部条件变化均会影响最终评估结果。针对某宾馆的案例分析表明，宾馆建筑对于分布式热电联产系统具有较好的适应性，可获得可观的减排收益，尤其以冬季效果最佳。综合常规“以电定热”模式和“以热定电”模式所形成的“电热互动”模式可使系统常年具有较好的动态环境收益。
