随着双碳目标的提出，储能是促进分布式光伏就地平衡消纳、降低配电网碳排放的重要方式，但是传统储能配置方案通常只考虑电力电量平衡，如何综合考虑电碳特性对储能的优化配置提出了更高的要求。首先，通过引入节点净负荷碳流率指标，对配电网进行集群划分，提出了一种基于电气距离和净负荷碳流率的配电网集群划分方法，提高了配电网管理的效率和碳排放管理的精准度。在集群划分的基础上进一步提出了一种计及配电网碳排放成本的储能配置方法，综合考虑碳排放成本和网损成本以及储能配置的经济性成本与收益，建立了储能碳平衡机制，量化了储能内部含碳量变化对配电网的影响，避免了二氧化碳排入或排出储能设备。最后，通过在安徽省某地配电网进行的算例仿真验证结果显示，所提方法与未配置储能系统相比配电网碳排放总量减少了11.12 %。

With the proposal of dual-carbon target, energy storage is an important way to promote distributed PV local balanced consumption and reduce carbon emissions from the distribution network, but the traditional energy storage configuration scheme usually only considers the electric power balance, and how to comprehensively consider the electric-carbon characteristics puts forward higher requirements for the optimal configuration of energy storage. Firstly, a cluster division method based on electrical distance and net load carbon flow rate is proposed by introducing the node net load carbon flow rate index for cluster division of distribution networks, which improves the efficiency of distribution network management and the accuracy of carbon emission management. On the basis of the cluster classification, an energy storage allocation method that takes into account the carbon emission cost of the distribution network is further proposed, which takes into account the carbon emission cost and network loss cost, as well as the economic cost and benefit of energy storage allocation, establishes a carbon balance mechanism for energy storage, quantifies the impact of the change of the carbon content within the energy storage on the distribution network, and avoids carbon dioxide emissions into or out of the energy storage equipment. Finally, the results of an arithmetic simulation in a distribution network in Anhui province show that the proposed method reduces the total carbon emissions of the distribution network by 11.12 % compared to the unconfigured energy storage system.
