摘要: 随着综合能源系统(integrated energy systems,IES)的技术发展和共享储能系统的普及,区域内部多个IES将存在能量交互,形成区域多综合能源系统(multi-integrated energy system,MIES)。研究计及电能和热能交互的MIES运行优化,考虑接入共享储能调整IES间的能量交互量,对优化IES内部机组出力、降低系统整体的运行成本具有重要意义。首先,构建了IES的设备出力和共享储能模型,考虑MIES内部各IES之间以及与外部能源网进行的电/热能交互情况,建立了考虑电热交互和共享储能的MIES运行优化模型;其次,采用混合整数线性规划方法对模型求解;最后,以区域内3个IES互联构成的MIES为例,分析了考虑电热交互以及接入共享储能系统对MIES经济性的影响。

Abstract: With the technological development of integrated energy systems (IES) and the popularity of the shared energy storage system (SESS), the multiple integrated energy systems (MIES) would be gradually formed by several IESs and their interactions. The optimal operation of MIES with power and heat interaction considering SESS, optimization for equipment output in IES and adjustment for energy exchange among IES can reduce the operation cost of the whole MIES. Firstly, the optimal operation model for MIES considering the electricity and heat interaction is proposed on the basis of common equipment output of IES and SESS, where the electricity and heat interaction among each IES in MIES and external grid. Secondly, the model is solved by mixed integer linear programming method. In the numerical test, MIES consisting of three IES are taken as an example to analyze the economy of MIES which are connected to SESS considering power and heat interaction.
