摘要
在“双碳”技术框架下,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。本文提出了一种绿色居住建筑用能碳排放指标精细化估算方法,基于非侵入式负荷辨识结果,计量电器能耗,考虑建筑光储系统出力与电网单位电能碳排放量时变性,计算间接碳排放因子。再考虑电器特性,估算直接碳排放因子,结合间接碳排放,得到实际碳排放量。最后,通过居民实际“源-荷”数据,估算用能碳排放指标,为建筑节能降碳调控策略提供数据支撑。
In the framework of dual carbon technology,there is a huge space for reducing building carbon emissions,and the traditional building energy consumption measurement can no longer meet the demand of energy saving and carbon reduction.In this paper,a refined estimation method of carbon emission index for green residential buildings is presented.This method based on the non-intrusive load identification results,measuring the energy consumption of electrical appliances,and calculating the indirect carbon emission factor by considering the time-varying power output of the building light storage system and the carbon emission per unit of electrical energy from the power grid.Then,considering the characteristics of electrical appliances,the direct carbon emission factor is estimated,and combined with the indirect carbon emission,the actual carbon emission is obtained.Finally,this paper uses the actual"source-load"data of residents to estimate the energy consumption carbon emission index,which provides data support for the energy-saving and carbon-reduction regulation strategy of buildings.
