Review on District-level Integrated Energy System Planning Considering Interconnection and Interaction

以互联互动为特征的区域综合能源系统(district-level integrated energy system,DIES)对建设清洁低碳、安全高效的现代能源体系至关重要。首先,从互联和互动两个维度,分别分析多能流耦合、多系统融合、多区域联合的互联形态和多环节、多主体、多时间尺度的互动机制对DIES的影响;然后,梳理DIES能源站和能源网络建模方法,抽象出能量转换与流动的本质特征;在此基础上,建立考虑互联互动的DIES规划基础模型,对比分析不同场景下能源站规划、能源网络规划和站网联合规划的目标函数与约束条件、不确定性因素处理方式和模型求解方法;最后,对考虑互联互动的DIES规划未来可能的发展方向进行展望。

The district-level integrated energy system(DIES), which is characterized by the interconnection and interaction, plays a significant role in constructing a clean, low-carbon, safe, and efficient modern energy system. This paper firstly analyzed the influences of the interconnection in the form of multi-energy coupling, multi-system integration, multi-district uniting and the influences of the multi-link, multi-agent, and multi-time scale interaction on DIES. Then, based on the models of the energy station and energy networks in DIES, the essential characteristics of energy conversion and energy flow were abstracted. On this basis, the general model of DIES planning considering the interconnection and interaction was established, in which the objective functions and constraints in different scenarios, modeling methods of uncertainties, and solving methods were compared. Finally, the possible development directions of the DIES planning considering the interconnection and interaction were proposed.
