摘　　要：为了推动生物质能的利用,解决沼气发电给综合能源系统带来较高碳排放的问题,提出一种考虑生物质燃气和电转气耦合的综合能源系统低碳优化调度策略。首先,构建沼气生产模型,引入改进变压吸附技术提纯沼气并回收二氧化碳;其次,引入电转气并与生物质燃气耦合,利用回收的二氧化碳为原料生产天然气,进一步减少系统碳排放;然后以设备运维成本、系统购售能成本和系统碳排放成本之和最小为目标,在MATLAB上调用Cplex进行优化求解;最后设置不同场景进行算例分析。结果表明:引入改进变压吸附技术提纯沼气使系统碳排放降低了21.7%,解决了沼气发电给系统带来过高碳排放的问题;电转气与生物质燃气耦合使系统碳排放和调度成本分别降低了7.6%和4.4%,提高了系统的低碳性和经济性。To promote the utilization of biomass energy and solve the problem of high carbon emissions brought by biogas power generation to integrated energy system,a low-carbon optimal scheduling strategy for integrated energy system considering coupling of biomass gas and power to gas is proposed.Firstly,a biogas production model is constructed,and the improved pressure swing adsorption(PSA)technology is introduced to purify biogas and recover carbon dioxide.Secondly,the power to gas is introduced and coupled with biomass gas,and the recovered carbon dioxide is used as raw material to produce natural gas,while reducing the system carbon emissions.Then,with the goal of minimizing the sum of equipment operation and maintenance cost,system energy purchase and sale cost and system carbon emissions cost,Cplex is called on MATLAB for optimization solution.Finally,different scenarios are set up for example analysis.The results show that,the introduction of the improved PSA technology to purify biogas reduces the system carbon emissions by 21.7%,which solves the problem of high carbon emissions brought by biogas power generation to the system.The coupling of power to gas and biomass gas reduces the system carbon emissions and dispatching costs by 7.6%and 4.4%,respectively.Thereby,the system’s low-carbon and economic performance is enhanced.
