| 摘要: |
| 针对气电耦合系统的优化调度问题，建立含气网掺氢的气电耦合系统模型，并考虑电制氢的精细化模型、掺氢气网的运行状态变化和严格的掺氢安全限制；同时在阶梯型碳交易机制的基础上，提出赏罚阶梯型碳交易机制，在碳配额出现剩余时设置阶梯型奖赏；进一步地综合考虑碳交易成本和运行成本，建立气电耦合系统低碳优化调度模型。最后，基于改进的IEEE 39节点电网模型和比利时20节点气网模型组成的系统进行仿真，采用CPLEX求解器对调度模型进行求解。通过分析对比4种调度场景的结果，验证了所提模型在降低碳排放、控制总成本和消纳弃风方面的有效性，分析了掺氢气网中不同热值计算方式和奖赏基准价格对调度结果的影响，并进行了奖赏基准价格的参考定价分析。 |

| Abstract: |
| Aiming at the optimal scheduling problem of natural gas-electricity coupling system, the natural gas-electricity coupling system model with hydrogen-mixed natural gas network is established, in which the refinement model of power to hydrogen, the variation of operating state for hydrogen-mixed natural gas network and the strict safety restrictions of hydrogen-mixed are considered. Meanwhile, based on the stepped carbon trading mechanism, the reward and punishment ladder-type carbon trading mechanism is proposed, setting the ladder-type reward when there is a surplus of carbon quota. Furthermore, considering the carbon transaction cost and operation cost comprehensively, the low-carbon optimal scheduling model of natural gas-electricity coupling system is established. Finally, the simulation is carried out based on the system composed of the improved IEEE 39-bus power grid model and the Belgian 20-node natural gas grid model, and CPLEX solver is used to solve the scheduling model. Through analyzing and comparing the results of four scheduling scenarios, the effectiveness of the proposed model in aspects of reducing carbon emission, controlling total cost and accommodating abandoned wind is verified. The effects of different calorific value calculation methods and reward benchmark price on scheduling results in hydrogen-mixed natural gas network are analyzed. In addition, the reference pricing of reward benchmark price is analyzed. |
