摘　　要：针对目前电力系统低碳调度中负荷侧降碳手段单一,且源-荷-储侧降碳方法协同性差的问题,文章提出了一种基于碳势指标的源-荷-储多维降碳耦合策略,建立了计及低碳经济目标的电力系统双层优化调度模型。首先,基于电力系统碳排放流理论建立负荷和储能的碳排放流追溯模型;其次,在负荷侧建立融合碳排放流理论的“价格-激励”双重低碳需求响应模型;在储能侧建立基于节点碳势的低碳调度模型;然后,构建具有分时电价与节点碳势特征的电力系统双层优化调度模型,上、下层模型分别以最优经济、最优低碳作为调度目标;最后,采用改进IEEE14节点系统完成算例分析。仿真结果表明,该调度策略能够深入挖掘系统的降碳潜力,有效增强系统的减碳能力,提高系统的经济效益。In response to the issues of limited carbon reduction methods on the load side and poor coordination of carbon reduction methods across generation, load, and storage in current low-carbon dispatching of power systems, a multi-dimensional carbon reduction coupling strategy based on carbon potential indicators is proposed. This involves the establishment of a dual-layer optimization dispatch model for the power system, which includes low-carbon economic objectives.Initially, a carbon flow tracing model for loads and energy storage is developed based on the theory of carbon emissions flow in power systems. Subsequently,a dual low-carbon demand response model integrating carbon flow theory is established on the load side, and a low-carbon dispatch model based on nodal carbon potential is developed for the energy storage side. Then, a dual-layer optimization dispatch model for the power system characterized by time-of-use electricity pricing and nodal carbon potential is constructed, with the upper and lower layers aimed at optimal economic and low-carbon objectives, respectively. Finally, the strategy is tested using a modified IEEE14-node system, and the simulation results demonstrate that this dispatch strategy can effectively tap into the system's carbon reduction potential, enhance its carbon reduction capability, and improve its economic benefits.
