摘　　要：电转气(power to gas,P2G)技术是提升综合能源系统灵活性与能源利用率的有效途径。为进一步发掘P2G对综合能源系统的可调节能力与碳减排影响,文章提出一种考虑需求响应和P2G参与碳交易市场的优化调度模型。根据系统负荷特性建立了电热综合需求响应模型;结合碳交易机制背景,考虑P2G对碳交易机制的激励作用,建立系统综合碳交易成本模型;以运行成本最小和弃风量最小为目标函数,建立了综合能源系统低碳调度模型,并通过三种场景对比验证所提模型的有效性。通过对需求响应调节能力、机组出力情况、碳价以及弃风惩罚系数分析发现,需求响应有效提高了系统经济型与用能灵活性;考虑综合碳交易成本模型下,合理制定碳价及弃风惩罚系数能有效促进系统低碳经济运行。P2G technology is an effective way to improve the flexibility and energy efficiency of the integrated energy system.In order to further explore the adjustability and carbon emission reduction impact of P2G on the integrated energy system,an optimal dispatching model considering demand response and P2G participation in the carbon trading market is proposed.A comprehensive demand response model for electricity and heat is established according to the system load characteristics.Combined with the background of the carbon trading mechanism,considering the incentive effect of P2G on the carbon trading mechanism,a systematic comprehensive carbon trading cost model is established.The minimum operating cost and the minimum amount of wind abandonment are used as the objective functions,a low-carbon dispatching model for an integrated energy system is established,and the effectiveness of the proposed model is verified by comparing three scenarios.Through the analysis of demand response adjustment capacity,unit output,carbon price and wind abandonment penalty coefficient,it is found that demand response effectively improves the system economy and energyflexibility;considering the comprehensive carbon trading cost model,the reasonably formulation of carbon price and wind abandonment penalty coefficients can effectively promote the low-carbon economic operation of the system.
