| 摘 要： | 在传统模式下，多区域综合能源系统（integrated energy system，IES）由于地理位置分散，往往都是独立运行，彼此间缺乏协调，难免存在资源配置不合理的问题，这不利于各区域的经济调度。文章首先提出一种多区域综合能源系统协调经济调度模型，其不仅能实现各自区域内的电热功率平衡，还能实现不同区域间的电热互补，然后采用分布式优化方法对模型进行求解。通过对比协调模式与传统的非协调模式，仿真结果表明，在该协调模式下，不同区域通过电能和热能交换，能够合理分配能源，实现综合能源系统的经济运行。从能源总需求量、储能设备调度结果和各区域间能源集线器（energy hub，EH）的能量交换情况3个方面验证了所构建模型的有效性。

| Abstract: | In traditional mode， multi-regional integrated energy system often operated individually due to geographical dispersion and lacks coordination between sub-regions， which causes an unreasonable resource allocation inevitably and is not conducive to economic scheduling of each sub-region. Firstly， a cooperative economic scheduling model for multi-region integrated energy system is proposed， which not only meets the energy demand of each sub-region， but also realizes the complementation of electric power and thermal power between different sub-regions. Secondly， a distributed optimization is used to solve the model. Finally， comparing the coordinated mode with the traditional non-coordinated mode， the simulation results show that， in the coordinated mode， different regions could distribute energy reasonably by exchanging electric power and thermal power and realize the economic operation of integrated energy system. The validity of the model is verified from three aspects: total energy demand， energy storage scheduling results and energy exchange of energy hubs between different regions. |
