摘　　要：针对目前低碳调度中负荷侧低碳手段单一且源荷两侧减碳方法相对独立缺乏联动的问题,在利用碳排放流引导多类型负荷需求响应模型的基础上,提出考虑利用碳势耦合源荷多降碳手段的电力系统双层低碳经济调度模型。上层模型基于阶梯碳交易市场,计算源侧的碳市场交易成本,并按照负荷分类进行针对性区域碳排约束,建立考虑源-荷碳势约束的电力系统低碳经济调度模型,求解机组初始调度方案;下层模型利用碳排放流理论,基于上层模型的调度方案计算负荷侧各节点碳势指标和碳排责任分摊量,建立负荷侧多类型需求响应模型,利用用户侧调节能力优化负荷分布进一步实现系统低碳效益。最后在考虑风电不确定性建模的前提下,基于改进的IEEE 30节点系统进行算例分析,结果表明所提调度方法能够有效促进风电消纳,降低碳排放量。Aiming at the current low-carbon scheduling on the load side of a single low-carbon means,and the source and load sides of the carbon reduction method being relatively independent of the lack of linkage,this study establishes a two-layer low-carbon optimization scheduling model of a power system considering the source-load carbon potential coupling in the market a few days ago.The upper model is based on the ladder carbon trading market,calculates the carbon market transaction cost of the source side,and establishes a low-carbon economic dispatch model of the power system considering the source-load carbon potential constraints in accordance with the load classification,and solves the initial scheduling scheme of the units;the lower model adopts the theory of carbon emission flow,and calculates the carbon potential indexes of each node of the load side and the carbon emission responsibility sharing amount,and establishes a two-layer low-carbon optimization dispatch model of the power system considering the source-load carbon potential constraints.The lower model employs the carbon emission flow theory to calculate the carbon potential index of each node on the load side and the carbon emission responsibility sharing amount based on the scheduling scheme of the upper model,establishes a multi-type demand response model on the load side,and utilizes the user-side regulation ability to optimize the load distribution to further realize low-carbon system benefits.Finally,under the premise of wind power uncertainty modeling,an example analysis is conducted based on the improved IEEE 30-node system,and the results indicate that the scheduling method can effectively promote wind power consumption and reduce carbon emissions.
