摘　　要：为准确核算新型电力系统用户侧的碳排放责任,促进低碳电力不断发展,在运用节点碳强度计算方法表征系统碳流分布和初步完成负荷侧碳排放责任量核算的基础上,创新性地结合综合负荷法,充分考虑用户当前阶段的峰荷特性,在修正前后碳排放责任总量保持不变的前提条件下,对负荷侧的初始碳排放责任进行修正分析。综合考虑负荷侧长期电力需求变化和减排能力特性,构建了反映用户长期用电特性的碳排放责任量分摊区间,并据此准确评估了各负荷节点对碳排放责任核算结果的满意度,为电力系统的低碳转型策略制定和需求侧响应能力建设指明了方向。在改进的IEEE 14节点系统的应用结果表明,相较于节点碳强度分摊方法的初始核算结果,基于用户用电特征的电力系统负荷侧碳排放责任核算结果兼具合理性和准确性,为电力行业的清洁低碳发展提供了数据支撑,具有一定的参考价值。To accurately estimate the carbon emission obligation of the user side of a new power system and promote the continuous development of low-carbon electricity,this study uses the node carbon intensity calculation method to characterize the carbon flow distribution of the system and preliminarily calculates the carbon emission obligation on the load side.Moreover,under the premise that the total carbon emission obligation allocation amount remains unchanged before and after correction,the initial carbon emission obligation on the load side is modified and analyzed based on an innovative combination of the comprehensive load method,where the peak load characteristics of the user at the current stage are fully considered.Next,considering the long-term changes in electricity demand and emission reduction capabilities on the load side,a carbon emission obligation allocation interval reflecting the long-term electricity consumption characteristics of the users was constructed.Based on this,the satisfaction of each load node with the carbon emission obligation accounting results was accurately evaluated,providing a direction for the formulation of low-carbon transformation strategies and the construction of demand-side response capabilities in the power system.The application results in the 14-node power system show that compared to the initial accounting results of the node carbon intensity allocation method,the load-side carbon emission obligation accounting results based on the user electricity consumption characteristics of the power system are both reasonable and accurate,providing data support for the clean and low-carbon development of the power industry,and have a certain reference value.
