摘　　要：为了减少综合能源系统(integrated energy system,IES)运行过程中的碳排放,提出一种基于条件风险价值(conditional value at risk,CVaR)的IES低碳调度模型。首先,利用CVaR理论评估IES中不确定性带来的风险,并引入碳交易机制,将碳交易成本纳入目标函数,综合考虑各种设备的约束,建立了低碳经济调度模型;其次,采用yalmip+cplex优化软件对模型进行求解,算例验证了此模型的经济性和低碳性;最后,分析了耦合设备和储能设备容量变化对调度结果的影响,可为IES低碳运行提供参考。In order to reduce the carbon emission in the operation of integrated energy system(IES),a low-carbon scheduling model of IES based on conditional value at risk(CVaR)is proposed in this paper.Firstly,CVaR theory is used to evaluate the risk of uncertainty in IES,and the carbon trading mechanism is introduced.And the carbon trading cost is included in the objective function and a low-carbon economic scheduling model is established considering the constraints of various equipment.Secondly,yalmip+cplex optimization software is used to solve the model,and verify the economic and low-carbon performance of the model.Finally,the influence of the capacity change of coupling equipment and energy storage equipment on scheduling results is analyzed,which can provide reference for IES low carbon operation.
