为提升可再生能源的消纳,平抑负荷波动,控制碳排放总量,提出计及需求响应和阶梯型碳交易机制的多能耦合综合能源系统优化调度模型,研究不同运行方式对优化调度的影响。首先,以系统运行成本和碳交易成本最小为目标,建立了考虑电、气、热、冷多能耦合的综合能源系统优化模型。然后,在优化能源供给侧出力的基础上,利用能源转换装置改善多能源互补能力;在用户需求侧建立综合需求响应模型,平滑负荷曲线。最后,利用CPLEX求解工具箱对模型求解。结果表明:计及多能耦合互补的区域综合能源系统供需双侧协同优化在有效降低碳排放量的同时,可进一步提升系统运行经济性。

To improve the consumption of renewable energy,stabilize the power load fluctuation and reduce the total carbon emissions,an optimal scheduling model of multi-energy coupling integrated energy system considering demand response and ladder-type carbon trading mechanism is proposed in this paper,and the influence of different operation modes on optimal scheduling is studied.First,with the objective of minimizing the system’s operation cost and carbon trading cost,an optimization model of integrated energy system considering the coupling of electricity,gas,heat and cold is established.On the basis of optimizing the output on the energy supply side,energy conversion devices are used to improve the complementary capability of multiple energy sources.On the user demand side,a comprehensive de⁃mand response model is established to smooth the load curve.Finally,the CPLEX solution toolbox is used to solve the model,and results show that the bilateral collaborative optimization of supply and demand of regional integrated energy system considering multi-energy coupling and complementarity can effectively reduce carbon emissions and further im⁃prove the operation economy of the system.
