用户侧碳排放强度评级及绿色电力证书分配研究

Study on Carbon Emission Intensity Rating of Power Consumer Side and Green Power Certificates Distribution

为提升绿色电力竞争力、引导电力用户参与绿色电力证书市场,以碳流追踪模型为基础,建立用户侧碳排放强度评级体系,并构建用户侧绿色电力证书分配模型,指导电网展开需求侧管理。利用碳流追踪模型评估用户侧碳排放强度,依据平均排放强度对用户进行排放强度评级;绿色电力证书分配模型根据用户排放分级状况,以全网用户排放强度差异最小为目标进行证书分配,可满足全网用户共同且有差别地承担减排责任的公平性准则。通过IEEE30节点算例模拟了某系统典型方式下的日运行状况,对算例节点进行了碳排放强度评级,基于碳流追踪的绿色电力证书分配模型,实现了系统绿色电力证书的完全有效分配,分配后的用户侧排放状况也达到了预期的目标。

In order to enhance green power＇s competitiveness and encourage power consumers to take part in the green power certificates market,this paper established a carbon emission intensity rating system of power consumer side and set up agreen power certificates distribution model based on the carbon emission flow tracing model,which can guide the grid＇s demand-side management.Carbon emission flow tracing results and average emission can help the system to rate carbon emission intensity.The green power certificates distribution model aims at minimum carbon emission intensity.The distribution model reflects the principle of shared but differentiated responsibilities for energy saving and expenditure reduction on power consumer side.This paper uses IEEE 30-bus system to simulate the daily operation of a practical power system,and nodal emission intensity can be rated by rating system and certificates distribution results meet the target.
