摘　　要：为了推动生物质能开发利用并提高综合能源系统运行能效,提出一种含改进生物质燃气BNG(biomass natural gas)和阶梯碳交易的综合能源低碳经济调度模型。首先,构建考虑二阶变压吸附的生物质燃气模型;其次,将生物质燃气耦合电转气和碳捕集系统,从而实现二氧化碳的利用与封存。然后,完善生物质燃气参与后的阶梯碳交易模型,以综合能源系统经济运行成本最小构建目标函数进行优化求解。最后,通过设置不同场景进行分析,验证所提模型能够有效提高系统的经济性以及低碳性。To promote the development and utilization of biomass energy while enhancing the operational energy effi⁃ciency of integrated energy systems(IESs),a low-carbon economic dispatching model of integrated energy including improved biomass natural gas(BNG)and ladder-type carbon trading is proposed.First,an improved BNG model with second-order pressure swing adsorption is constructed.Second,the BNG is coupled with a power-to-gas system and a carbon capture system,thus realizing the utilization and storage of carbon dioxide.Third,the ladder-type carbon trad⁃ing model incorporating the BNG is enhanced,and an objective function is formulated to minimize the economic opera⁃tion cost of IES,which is further optimized and solved.Finally,various scenarios are configured for analysis,and it is validated that the proposed model can effectively enhance the system’s economic and low-carbon performance.
