摘要
“双碳”目标对我国现有产业结构和能源结构提出了更高要求,建筑碳排放具有巨大的降低空间,传统建筑能耗计量已无法满足节能降碳需求;提出一种含光储直柔的建筑运行过程中用能碳排放指标精细化估算方法,考虑建筑光储系统出力与电网单位电能碳排放量时变性,通过计算建筑内各负荷的间接碳排放量及直接碳排放量获取一天实时分项碳排放模型;该估算方法为设计阶段进行低碳建筑减碳方案对比与确认提供有效技术支持,为低碳建筑“光储直柔”一体化设计配置与调控提供关键数据支撑。
The“dual carbon”goals have put forward higher requirements for existing industrial structure and energy structure in China.There is a huge space for carbon emission reduction of buildings and energy consumption measurement of traditional buildings can no longer meet the demand for energy conservation and carbon reduction.This dissertation proposes a refined estimation method for energy carbon emissions during the operation of buildings with photovoltaic,energy storage,direct current and flexibility(PEDF).Considering the time‑varying relationship between the output of the building’s photovoltaic,energy storage system and the carbon emission of unit electrical energy from the power grid,the method can obtain a daily real‑time itemized carbon emission model by calculating the indirect and direct carbon emissions of each load in the building.This estimation method provides effective technical support for comparing and confirming carbon reduction schemes of low‑carbon buildings during the design phase and offers key data support for PEDF integrated design,configuration and regulation of low‑carbon buildings.
