摘　　要：为应对电转气P2G(power-to-gas)和碳捕集系统CCS(carbon capture system)在可再生能源出力不足时耦合失效的问题,考虑对常规CCS引入CO_(2)储液罐以加强P2G和CCS的耦合。首先,构建储液式CCS和P2G的耦合模型,利用储液罐将CCS捕集的CO_(2)时移至可再生能源富足时段,供P2G再利用;其次,构建储液式CCS与P2G耦合的电热气综合能源系统日前优化调度模型;最后,以北方某工业园区为例进行仿真。结果证明所提模型可以充分利用CCS捕集的CO_(2),从而获得更好的经济和环境效益。To address the issue of decoupling between power-to-gas(P2G)and carbon capture system(CCS)when the renewable energy output is insufficient,a CO_(2) liquid storage tank is introduced on the basis of conventional CCS to enhance the coupling between P2G and CCS.First,a coupled model of solvent-storaged CCS and P2G is constructed,and the liquid storage tank is used to transfer the CO_(2) captured by CCS to the period when the renewable energy is abundant for reuse by P2G.Second,a day-ahead optimal dispatching model for an electricity-heat-gas integrated energy system with coupling solvent-storaged CCS and P2G is constructed.Finally,an industrial park in North China is taken as an example for simulation,and it is verified that the proposed model can fully utilize the CO_(2) captured by CCS,thereby achieving better economic and environmental benefits.
