摘　　要：为了达成双碳目标,针对含多种能源类型、通过直流联络线互联的多区域新型电力系统,提出了1种跨区域低碳优化调度模型,将碳排放成本价格以及碳排放权约束引入跨区域优化调度模型,研究考虑碳约束的跨区域优化调度模型对各类型机组出力、系统总成本、碳排放量的影响。在3个10机39节点系统上进行仿真,并通过目标级联分析法进行求解,验证了跨区域低碳优化调度模型可以通过提高低碳排放机组的出力、降低高碳排放机组的出力来降低系统的总碳排放量。之后研究了跨区域低碳优化调度模型下减排力度的增大对机组成本及机组改造意愿的影响,结果表明机组改造可以有效降低系统碳排放量及总成本。In order to achieve the goal of carbon neutral and carbon peak,a cross-region low-carbon optimal dispatch model is proposed for new multi-region interconnected by DC tie-lines.By introducing the carbon emission cost price and carbon emission right constraints into the cross-region optimal dispatch model,the impact of cross-region optimal dispatch model considering carbon constraints on the output of each type of unit,total system cost and carbon emission is investigated.Through the simulation on three 10-unit 39-node system,solved by analytical target cascading,it is verified that the cross-region low-carbon optimal scheduling model can reduce the total system carbon emissions by increasing the output of low-carbon emitting units and decreasing the output of high-carbon emitting units.The impact of increasing emission reduction under the low-carbon optimal dispatch model on the unit cost and the willingness of the retrofitted unit is investigated.The results show that unit retrofits can effectively reduce system carbon emissions and total costs.
