摘要
通信和信息技术的提升极大地增强了配电网的可观性与可控性,需要进一步从信息物理系统(cyber physical system,CPS)的角度研究配电网的运行特性。主要研究基于CPS的配电网系统综合建模与交互机理。首先提出配电系统与配电信息系统的统一建模方法;其次研究了配电网CPS动态交互影响机理,以分布式电源为智能控制和处理终端,构建配电网CPS动态交互综合模型;最后分析了配电网CPS中通信故障对物理环节的动态影响并进行测例仿真,进而验证了模型的有效性。
The improvement of communication and information technology has greatly enhanced the observability and controllability of distribution network.It is necessary to further study the operation characteristics of distribution network from the perspective of cyber physical system(CPS).This paper mainly studies the CPS-based integrated modeling and interaction mechanism of distribution network system.Firstly,a unified modeling method is proposed for distribution system and distribution information system.And then the dynamic interactive influence mechanism of distribution network CPS is studied,and the integrated CPS dynamic interaction model of distribution network is constructed using the distributed generation as the intelligent control and processing terminal.Finally,the dynamic impact of communication faults in distribution network CPS on physical links is analyzed and simulated through testing cases,which has proved the validity of the model.
