摘　　要：针对综合能源系统能源结构改变导致系统灵活性和环保性下降的问题,提出考虑功率可调节裕度的区域综合能系统多时间尺度优化调度模型。首先,重点分析净负荷预测误差和可调度机组对系统可调节能力的影响;其次,引入阶梯式碳交易机制,建立日前调度模型,以实现系统低碳经济运行;然后,以系统动态功率可调节裕度最大为目标,建立日内滚动优化调度模型;最后,构建综合能源系统,并设置多个场景,通过CPLEX进行多目标优化计算。仿真结果表明,所建优化模型提高系统的可调节裕度。因此,所提出的优化调度方法可实现系统在低碳经济运行的同时,提高系统多能源功率的可调节裕度,增强系统的灵活性。Aiming at the problem that the energy structure change of integrated energy system leads to the decrease of system flexibility and environmental protection,a multi-time scale optimal scheduling model for regional integrated energy system considering power adjustable margin is proposed in this paper.Firstly,the influence of net load forecasting errors and dispatchable units on the system’s adjustable capacity is analyzed.Secondly,based on the introduction of the stepped carbon trading mechanism,the day-ahead scheduling model considering the dual response mechanism of supply and demand is established to realize the low-carbon economic operation of the system.Then,the optimal scheduling model of intra-day rolling is established with the goal of maximum adjustment margin of dynamic power.Finally,the integrated energy system is constructed and multiple scenarios are set up to perform multi-objective optimization calculations through CPLEX.The simulation results show that the optimized model improves the adjustable margin of the system.Therefore,the proposed optimal scheduling method can realize the system running in low carbon economy,improve the adjustable margin of multi-energy power of the system and enhance the flexibility of the system.
