摘　　要：为了促进电力低碳化、提高虚拟电厂的低碳经济性,引入电解熔融碳酸盐(electrolytic molten carbonate,EMC)设备捕集燃气轮机(gas turbine,GT)热电联产所产生的CO_2,并对电转气(power to gas,P2G)设备精细化建模,建立P2G和电解熔融碳酸盐协同的虚拟电厂低碳经济调度模型.首先,考虑到可再生能源的不确定性,通过拉丁超立方抽样与Kantorovich场景削减技术生成典型的风电出力场景.然后,基于EMC的电化学原理,构建两阶段P2G、GT和EMC耦合模型.接着,引入阶梯式碳交易机制引导虚拟电厂控制碳排放,以虚拟电厂运行总成本最低为目标,建立低碳经济调度模型.最后,通过设置不同方案进行对比分析,验证所建立的模型在提升虚拟电厂经济效益、增强风电消纳能力的同时,能够有效降低系统碳排放.In order to promote the low-carbon power generation and improve the low-carbon economy of virtual power plants,the equipment of electrolytic molten carbonate is introduced to capture the carbon dioxide generated by gas turbine cogeneration,and the equipment of power to gas(P2G)is finely modeled.Meanwhile,a low-carbon economic dispatch model of virtual power plant with P2G and electrolytic molten carbonate synergy is established.Firstly,a typical scenario of wind power output is generated by Latin hypercube sampling and Kantorovich scenario reduction technology considering the uncertainty of renewable energy.Then,a two-stage P2G,GT and EMC coupling model is constructed based on the electrochemical principle of EMC.Moreover,a tiered carbon trading mechanism is introduced to guide virtual power plants to control the carbon emissions,and a low-carbon economic dispatch model is established with the goal of minimizing the total operating cost of virtual power plants.Finally,it is verified by setting up the different schemes for comparative analysis that the established model can effectively reduce the carbon emissions of the system while the economic benefits of the virtual power plant is improved and the wind power absorption capacity is enhanced.
