摘　　要：在“双碳”目标下,为明确配电网中具体网损流向,减小传统忽略网损的碳势计算方法存在的误差,构建了计及网损分摊的节点碳势计算模型,通过网损分摊模型将网损与电流耦合,使传统网损计算方法中二次表达式能够分解,可以计算任意发电机节点与其他节点间的网损,以发电成本和支付碳税最低为经济目标,通过粒子群算法计算配电网最优潮流。结果表明,计及网损的节点碳势计算方法可以准确计算系统节点碳势分布,并满足碳排放流守恒,系统中接入新能源机组可以降低系统整体碳势,并有效抑制系统中高碳排机组出力。For the"dual carbon"goal,this paper aims to clarify the specific flowing direction of network loss in the power distribution network,diminish the error in traditional carbon flow calculating method with network loss neglected,and establish a nodal carbon calculation model considering network loss allocation.The study is performed by coupling network loss with current to solve the indecomposable problem of quadratic equation,calculating the network loss between any generator node and other nodes;and conducting the optimal power flow calculation by using particle swarm optimization algorithm for the economic goal of minimizing power generation costs and paying carbon taxes.The results show that the node carbon potential calculation method considing network losses can accurately calculate the carbon potential distribution of system nodes,and meet the conservation of carbon emission flow.Connecting new energy units to the system can reduce the overall carbon potential of the system and effectively suppress the output of high carbon emission units in the system.
