| 摘要: |
| 为提升综合能源系统的环境效益与经济效益，促进可再生能源消纳并平抑系统波动，提出考虑垃圾焚烧烟气处理与电转甲醇的综合能源系统优化调度模型。首先，在垃圾焚烧电厂中，将脱硫、脱硝、碳捕集和烟气储存装置一同构成烟气处理系统，减少环境污染的同时实现垃圾焚烧发电与烟气处理环节时间上的解耦。其次，构建烟气处理系统-电转甲醇-甲醇燃料电池协同运行框架，碳捕集所得CO2作为电转甲醇原料，生成的甲醇可直接获得商品收益，亦可通过甲醇燃料电池维持系统供电稳定性。最后，提出奖惩差异型阶梯碳交易机制以约束系统碳排放，建立以系统运行净成本最小为目标的优化调度模型。算例结果表明，该模型具备“削峰填谷”效用并能有效促进系统绿色、经济运行。 |

| Abstract: |
| o improve the environmental and economic benefits of an integrated energy system, promote the consumption of renewable energy and stabilize system fluctuation, this paper proposes an optimal scheduling model of an integrated energy system considering waste incineration flue gas treatment and power-to-methanol conversion. First, in the waste incineration power plant, the desulfurization, denitrification, carbon capture and flue gas storage devices together constitute a flue gas treatment system to reduce environmental pollution and realize the decoupling of waste incineration power generation and flue gas treatment. Secondly, a coordinated operational framework of a flue gas treatment system-electric-to-methanol-methanol fuel cell is constructed. The CO2 obtained by carbon capture is used as the raw material of electricity-to-methanol, and the generated methanol can directly obtain the commodity income, and the power supply stability of the system can be maintained through the methanol fuel cell. Finally, a reward-penalty differential ladder carbon trading mechanism is proposed to constrain the carbon emissions of the system, and an optimal scheduling model with the goal of minimizing the net cost of system operation is established. The results show that the model has the effect of “peak load shifting” and can effectively promote the green and economic operation of the system. |
