摘　　要：随着大规模分布式电源(distributed generation,DG)和可调负荷接入配电网,低成本最大化减排对配电网低碳发展至关重要。为此,该文提出一种基于负荷碳排放特征的配电网源荷协同规划方法。首先,基于配电网的碳势和净负荷曲线,建立了考虑用电碳排量、距离低碳度、趋势低碳度和低碳用电率的负荷碳排放特征量化模型,得到区域电网内各配电网的低碳规划优先级;其次,以碳排放量最低为目标,建立了配电网源荷协同规划模型,得到响应后负荷特性曲线、DG接入种类及容量,融合DG发出的零碳电力和柔性负荷的灵活调节能力以充分降低系统碳排放;最后,在改进后的IEEE30节点系统上通过仿真对所提方法的碳减排效益进行分析与验证。With large-scale Distributed Generation(DG)and adjustable loads connected to the distribution grid,maximizing emission reduction at low cost is crucial for low-carbon development of distribution grids.To this end,this paper proposes a source-load cooperative planning method for distribution networks based on load carbon emission characteristics.Firstly,based on the carbon potential and the net load curve of the distribution network,a quantitative model of load carbon emission characteristics considering the carbon emission of electricity consumption,distance low carbon,trend low carbon,and low carbon electricity consumption rate is established to get the priority of low carbon planning for each distribution network within the regional grid;secondly,to minimize carbon emission,a source-load cooperative low carbon planning model of the distribution network is established to get the post-response load characteristic curve,the DG access type and capacity,integrating the zero-carbon power issued by DG and the flexible regulation capability of flexible loads to reduce the system carbon emissions entirely;finally,the carbon emission reduction benefits of the proposed method are analyzed and verified by simulation on the improved IEEE30 node system.
