摘　　要：为充分挖掘需求侧资源响应潜力,最大限度地提升系统的减碳能力,提出一种基于碳排放流理论的低碳-超碳需求响应模型,建立电力系统源荷协同降碳的日前-日内两阶段优化调度策略。首先,在源侧考虑碳交易机制,引入奖惩阶梯型碳交易成本模型;其次,针对负荷的可调度特性和不同时间尺度下的响应差异性,建立日前低碳价格型、日内超碳激励型需求响应模型,通过源荷协同配合提升系统的低碳性能;然后,构建融合低碳-超碳需求响应的电力系统日前-日内两阶段优化调度策略,电力系统以日运行总成本最小进行调度,荷侧根据系统碳排放情况合理改变自身用能行为,以消费者剩余最大进行优化调整;最后,采用改进IEEE-30节点系统完成算例分析。仿真结果表明,所提调度策略能有效促进需求响应的积极性,极大降低系统的碳排放,平衡系统的低碳性和经济性。In order to fully exploit the response potential of demand-side resources and maximize the carbon reduction capability of the system,a low-carbon and ultra-low-carbon demand response model based on carbon emission flow theory is proposed,and a day-ahead and ctwo-stage optimization dispatch strategy for coordinated carbon reduction in power systems is established.On the generation side,the carbon trading mechanism is considered,and a reward-penalty tiered carbon trading cost model is introduced.In allusion to the dispatchable characteristics of the load and the response differences under different time scales,a day-ahead low-carbon price-based and intra-day ultra-low carbon incentive demand response model is established to improve the low-carbon performance of the system by means of source-load coordination.A day-ahead and intra-day two-stage optimization dispatch strategy for the power system is constructed integrating low-carbon and ultra-low carbon demand response is proposed.The power system is dispatched to minimize total daily operating costs,and the load side can reasonably adjust its energy consumption behavior according to the system carbon emission situation,so as to optimize and adjust to the maximum consumer surplus.The improved IEEE-30 bus system is used for the case analysis.The simulation results show that the proposed dispatch strategy can effectively promote demand response activity,greatly reduce the system's carbon emissions,and balance the system's low-carbon performance and economic efficiency.
