摘　　要：随着中国“碳达峰·碳中和”战略的不断推进,综合能源系统的绿色低碳转型迫在眉睫。针对传统碳捕集电厂灵活性较差、风电并网难以消纳等问题,提出一种含碳捕集电厂与氢能多元利用的综合能源系统低碳经济调度模型。首先,引入储液罐对传统碳捕集电厂进行改造,提高电厂应对风电波动的运行灵活性;其次,构建含两段式电转气、氢燃料电池、储氢罐和掺氢热电联产在内的氢能多元利用结构,以充分挖掘氢能利用与碳捕集电厂的协同运行潜力。在此基础上,引入阶梯碳交易机制,建立以碳交易、碳封存、燃煤及购气成本之和最小为优化目标的低碳经济调度模型。算例结果表明,文中模型能够有效提高系统的风电消纳水平和能源利用效率,具有显著的低碳经济效益。此外,碳交易基准价格的合理设定能够引导系统提高碳捕集水平。With the continuous promotion of“carbon emission peak and carbon neutrality”strategy in China,the green and lowcarbon transformation of integrated energy systems is imminent.Aiming at the problems of poor flexibility of traditional carbon capture power plants and the difficulty in integrating wind power into the grid,a low-carbon economic dispatch model of the integrated energy system considering carbon capture power plants and multi-utilization of hydrogen energy is proposed.Firstly,the traditional carbon capture power plant is reformed by introducing a liquid storage tank to improve the operation flexibility of the power plant to deal with wind power fluctuations.Secondly,a multi-utilization structure of hydrogen energy including two-stage power-to-gas,hydrogen fuel cell,hydrogen storage tank and hydrogen-doped combined heat and power is constructed to fully exploit the coordinated operation potential of hydrogen energy utilization and the carbon capture power plant.On this basis,a cascaded carbon trading mechanism is introduced to establish a low-carbon economic dispatch model with the optimization objective of minimizing the sum of carbon trading,carbon sequestration,coal and gas purchase costs.The simulation results show that the proposed model can effectively improve the wind power accommodation level and energy utilization efficiency of the system,and has significant low-carbon economic benefits.In addition,the carbon trading benchmark price can be set properly to guide the system to increase the level of carbon capture.
