城市空间结构对区域分布式能源系统节能减排效果的影响分析
Influence of urban spatial structure on energy and environmental performances of regional distributed energy system
摘要：
以区域分布式能源系统为研究对象，构建了以区域建筑混合比为特征参数的需求侧负荷分析模型及考虑部分负荷特性的供给侧解析模型，并提出了系统节能减排评价指标。针对由办公建筑、综合商场和居住建筑所构成的区域空间的不同组合模式进行了数值分析，结果表明，从区域分布式能源系统导入的节能性和环境性角度，均存在区域内建筑的最佳混合比。考虑到系统的部分负荷特性，对于任一具有特定空间结构的区域建筑群，均存在最佳系统容量，使得区域分布式能源系统取得最大节能减排效果。
Abstract：
Taking a regional distributed energy system as the research object, develops a demand-side load analysis model with the regional building mixing ratio as the characteristic parameter and a supply-side analytical model considering the partial load characteristics. Proposes an evaluation index of energy efficiency and emission reduction. According to the numerical analysis of different regional space combinations of office, commercial and residential buildings, the results show that there exist optimal mixing ratios of regional buildings from the viewpoints of both energy saving and environment introduced by the regional distributed energy system. Taking into account the partial load characteristics of the system, for a regional complex with specific spatial structure, there is an optimal system capacity, which can realize the best energy and environmental performances for the regional distributed energy system.
