摘要
配电系统正演进成为包含电、气、热等多种能源综合配置的平台,需要满足点对点能量传输需求,而现有配电系统的树状辐射结构难以满足。文中提出了蜂巢状综合能源配电系统(HIEDS)的组网结构与运行方式。首先,提出了HIEDS的组网结构,包括微网之间的柔性互联方式以及综合能源基站等核心装备;接着,分别提出了以运行经济性、负载均衡性为目标的HIEDS优化运行模型;最后,通过算例分析了HIEDS在不同场景下的运行特征,并与其他典型微网互联结构进行了对比。结果表明,HIEDS运行更加灵活,可提高系统运行的经济性与可靠性。文中研究将为综合能源配电系统的结构优化提供理论基础。
The distribution system is evolving into an integrated trading platform for multiple energy including electricity,gas and heat,which is necessary to meet the demand of point-to-point energy transaction.However,the existing dendritic radiation structure of distribution system is difficult to meet the demand.The networking structures and operation modes of honeycomb integrated energy distribution system(HIEDS)are proposed in this paper.First,the networking structures of HIEDS are proposed,including the flexible interconnection mode between microgrids and key equipment such as integrated energy base stations.Then,the optimal operation models of HIEDS aiming at operation economy and load balance are proposed.Finally,the operation characteristics of HIEDS in different scenarios are analyzed through cases,and compared with other typical microgrid interconnection structures.The results show that HIEDS operates more flexibly and can improve the economy and reliability of system operation.The research in this paper provides a theoretical basis for the structural optimization of integrated energy distribution systems.
