基于碳流追踪的居民碳排放核查方法研究

Research on resident carbon emission verification method based on carbon flow tracking

随着中国“双碳”工作的逐步推进,居民碳排放核查工作重要性日益增加。为解决居民碳排放核查中存在的分析颗粒度大、核查准确率低的问题,提出了一种基于碳流追踪的居民碳排放核查方法。首先,采用智能家居采集居民的屋顶光伏、储能、各类用能设备的能耗情况;其次,采用碳流追踪技术,实现居民家庭用能设备碳排放的正向追踪,屋顶光伏、储能反向供电的碳排放逆向追踪和双向损耗碳流分摊;在此基础上,核定居民的碳排放量。最后,在中国南方某城市进行实例验证,其结果表明:文中所提方法可有效提升居民碳排放核查颗粒度,提升碳排放核查准确率。

With the gradual progress of China’s“dual carbon”work,the carbon emission verification of residents has become increasingly important.In order to solve the problems of large analysis granularity and low verification accuracy in resident carbon emission verifica-tion,a resident carbon emission verification method based on carbon flow tracking is proposed.First,smart home is used to collect the en-ergy consumption of residents’roof photovoltaic,energy storage and various energy consuming devices.Second,carbon flow tracking tech-nology is adopted to realize the positive tracking of carbon emissions of household energy equipment,the reverse tracking of carbon emis-sions of roof photovoltaic and reverse power storage,and the two-way carbon flow allocation of loss.On this basis,the carbon emissions of residents are verified.Finally,a case study is conducted in a city in southern China,and the results show that:the proposed method can ef-fectively improve the particle size of residents’carbon emission verification and the accuracy of carbon emission verification.
