摘要
为提高能源利用率和降低碳排放,提出一种含余热回收利用的垃圾焚烧电厂-电转气(P2G)的综合能源系统经济运行策略。首先考虑垃圾焚烧电厂-P2G的协同运行,引入细化电转气两阶段运行过程,在传统电转气的基础上加入氢燃料电池以减少能量阶梯损耗,并将甲烷化反应热回收利用;其次为提高垃圾焚烧能源利用效率,考虑加装含水源热泵的余热回收装置,通过消耗部分电能来回收烟气余热以及消纳风电,并增设CO_(2)分离装置,结合P2G将回收的CO_(2)合成CH4,实现碳的循环利用;最后基于阶梯式碳交易机制构建以系统运行成本最小为目标的电-热综合能源系统优化模型,利用GUROBI建模优化引擎对此模型进行求解,结果验证所建模型的有效性。
In order to improve energy utilization and reduce carbon emissions,this paper presents a integrated energy system economic operation strategy of incineration power plant power-to-gas(P2G)with waste heat recovery.Firstly,consider the coordinated operation of Incineration power plant-P2G,introduce the refined Power-to-gas two-stage operation process,add hydrogen fuel cells on the basis of traditional power-to-gas to reduce the energy ladder loss,and recycle the methanation reaction heat.Secondly,in order to improve the energy utilization efficiency of incineration,it is considered to install a waste heat recovery device containing a water source heat pump to recover the waste heat of flue gas and consume some electric energy,sourced from wind power,and add the CO_(2) separation device to combine the recovered CO_(2) with P2G to synthesize CH4 to achieve carbon recycling.Finally,within the framework of a tiered carbon trading mechanism an IES optimization model for electricity-heat with the goal of minimizing the system operating cost is constructed,and the GUROBI modeling optimization engine is used to solve this model.The results verify the effectiveness of the model.
