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CO₂分离装置,结合P2G将回收的CO₂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。

Abstract

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 CO₂ separation device to combine the recovered CO₂ 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.
