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.
