计及分布式发电的电力系统全流程实时碳计量体系研究

Research on real-time carbon measurement system for the entire process of power system considering distributed generation

碳排放的准确计量是实现“双碳”目标的数据支撑,电力行业作为首个进入全国碳交易市场的重点行业其准确的碳计量具有重要意义。现阶段电力行业的碳计量采用统一的碳排放因子计算,且各个环节单独计量,这种方式碳排放因子颗粒度较大、实时性差且无法体现电力系统各环节的关联性和特征,区域分布式发电系统的加入对整体碳排放强度的影响无法快速体现。因此,运用碳排放流理论将电力系统发输变配用各个环节有机结合,建立了计及分布式发电的电力系统全流程实时碳计量体系,提出电力系统全流程各环节的碳排放计算方法。该方法能够提高电力系统的碳排放计量实时性,提升计量精度,反映电力系统碳排放变化情况,助力“双碳”目标实现。

Accurate measurement of carbon emissions is the data support for achieving the"dual carbon"goal.As the first key industry to enter the national carbon trading market,accurate carbon measurement in the power industry is of great significance.At present,the carbon measurement in the power industry adopts a unified carbon emission factor calculation and each link is measured separately.This method has high particle size,poor real-time performance,and cannot reflect the correlation and characteristics of each link in the power system.The addition of regional distributed power generation systems cannot quickly reflect the impact on the overall carbon emission intensity.Therefore,this paper applies the carbon emission flow theory to organically combine various links of power system transmission and distribution,establish a real-time carbon measurement system for the entire process of the power system that takes into account distributed generation,and propose a carbon emission calculation method for each link of the entire process of the power system.This method can improve the real-time measurement of carbon emissions in the power system,improve measurement accuracy,reflect changes in carbon emissions in the power system,and assist in achieving the"dual carbon"goal.
