Abstract

In order to promote the low-carbon and clean transition of the energy system and the local consumption of clean energy such as wind and light, a low-carbon and economic scheduling method of the integrated energy system taking into account the coupling of oxygen-enriched combustion-P2A-P2G is proposed. Firstly, an oxygen-enriched combustion carbon capture model is established on the side of the thermal power unit, and the oxygen produced by P2G is used for oxygen-enriched combustion, and part of the captured CO₂ is used for P2G to produce methane. Secondly, the multi-purpose utilization of hydrogen produced by P2G is considered, and it is used for ammonia production by P2A in addition to methane production and used for ammonia mixed combustion in the thermal power unit to realize the oxygen-enriched combustion-P2A-P2G coupling, at the same time, under the demand response and stepped carbon trading mechanism, a low-carbon economic dispatch model is established with the lowest total operating cost of the integrated energy system. The final example results show that the proposed model can effectively reduce the operating cost and carbon emissions of the integrated energy system.
