摘　　要：西北地区新能源发展迅速,充分利用当地独有的光热资源优势,同时结合火电低碳化改造与新能源协同运行,有利于推动当地能源系统绿色低碳转型。为尽最大限度地提升系统的减碳能力,提出一种基于源荷协同降碳的超碳需求响应模型,将动态碳排放因子作为分时电价的惩罚因子,从而将源侧碳信号传递至荷侧,驱使用户侧进行低碳性状态转移。首先,在日前调度阶段,构建预调度-再调度两阶段调度运行机制,再调度根据预调度的系统状态信息进行超碳需求响应,来深度降低系统碳排量。其次,将光热电站引入综合能源系统,与风电场、碳捕集电厂协同运行,从而构建高比例新能源场景,来验证超碳需求响应在此场景下的减碳效益。最后,建立了基于超碳需求响应的预调度-再调度两阶段低碳调度模型。经算例仿真分析表明,所提源荷协同降碳的新思路能有效提高系统的减碳能力,深入挖掘系统的降碳空间,提升系统的经济效益。With the rapid development of new energy in the northwest of China,making full use of the unique advantages of local light and heat resources,combined with the low-carbon transformation of thermal power and the coordinated operation of new energy,is conducive to promoting the green and low-carbon transformation of the local energy system.To maximize the carbon reduction capacity of the system,this paper proposes an ultra-carbon demand response model based on source-load collaborative carbon reduction.The dynamic carbon emission factor is used as the penalty factor of the time-of-use price so that the source-side carbon signal is transmitted to the load side,driving the user side to carry out low-carbon state transfer.Firstly,in the day-ahead scheduling stage,a two-stage scheduling mechanism of pre-scheduling-re-scheduling is constructed.The re-scheduling responds to the ultra-carbon demand according to the system status information of the pre-scheduling to reduce the system carbon emission in depth.Secondly,the concentrating solar power plant is introduced into the integrated energy system to operate in coordination with the wind farm and the carbon capture power plant to construct a high proportion of new energy scenarios to verify the carbon reduction benefits of the ultra-carbon demand response in this scenario.Finally,a pre-scheduling and rescheduling two-stage low-carbon scheduling model based on super-carbon demand response is constructed.The simulation analysis of the example shows that the new idea of source-load synergistic carbon reduction can effectively improve the carbon reduction capacity of the system,deeply explore the carbon reduction space of the system,and improve the economic benefits of the system.
