摘　　要：为应对电力系统存在的弃风、碳排放较高等问题,基于碳排放流理论提出了一种电-气互联系统源荷互动低碳经济调度模型。基于电力系统碳排放流计算方法,推导得到考虑气网动态特性的天然气系统碳排放流计算方法;构建以储液罐装置为主的储碳系统(CSS),CSS与火电机组(TU)、风电机组(WT)、电转气(P2G)设备组成TU-CSS-P2G-WT的联合运行方式;源侧以系统日运行总成本最小计算得到能源网络的碳势时空分布,荷侧根据源侧的碳势信号,基于低碳响应机制建立激励型低碳需求响应模型,合理调整用能行为最小化用户购能总成本;建立源荷互动两阶段低碳经济调度模型,并利用GUROBI进行求解。通过改进由IEEE 39节点和比利时20节点构成的电-气互联系统进行算例分析,验证了所提模型的低碳经济性和灵活性。In order to solve the problems of wind abandonment and higher carbon emissions in the power system,a low-carbon economic dispatching model of source-load interaction for the electricity-gas system based on carbon emission flow theory is proposed.Based on the carbon emission flow calculation method of the power system,the calculation method of carbon emission flow for the natural gas system considering the dynamic characteristics of the gas network is derived.The joint operation mode of carbon storage system(CSS)mainly composed of liquid storage tank,thermal unit(TU),wind turbine(WT),and power-to-gas(P2G)equipment is established as TU-CSS-P2G-WT.The carbon intensity spatiotemporal distribution of the energy network is calculated with the minimum daily total operating cost of system on the source side,while on the load side,an incentive low-carbon demand response model based on the carbon intensity signal from the source side and the low-carbon response mechanism is established,and minimize the user’s total energy purchase cost by regulating energy consumption behavior reasonably.A two-stage low-carbon economic dis⁃patching model of source-load interaction is built and solved by using GUROBI.Through the case study analysis of the improved electricity-gas system composed of IEEE 39-bus system and Belgium 20-node sys⁃tem,the low-carbon economy and flexibility of the proposed model are verified.
