摘要
针对极端灾害可能使智能配电网信息物理系统中通信网络和物理网络同时发生故障,而现有故障恢复策略处理此类问题时效率低,得不到最优方案。文章提出一种考虑通信-物理耦合关系的有源配电网灾后故障恢复策略,首先利用图论的知识对通信网络和物理网络之间耦合关系进行建模,在此基础上,考虑孤岛划分、网络重构以及动态协调通信-物理系统的检修策略建立了有源配电网通信网络和物理网络协调恢复模型,求解此故障恢复策略得到最优的考虑通信-物理耦合关系的有源配电网灾后协调恢复方案。最后,以通信网与改进的IEEE33节点系统为例,对所提多种优化方案的结果进行分析,验证了该文所提策略的优越性。
In response to the possibility of extreme disasters causing communication and physical network failures in the smart distribution network information system(smart distribution network CPS),existing fault recovery strategies are inefficient in dealing with such problems and cannot obtain optimal solutions.The article proposes a post-disaster fault recovery strategy for active distribution networks,considering the coupling relationship between communication and physical networks.Firstly,the coupling relationship between communication networks and physical networks is modeled using graph theory.Based on this,a coordinated recovery model for active distribution network communication networks and physical networks is established by considering island partitioning,network reconstruction,and dynamic coordination of communication and physical system maintenance strategies.Solving this fault recovery strategy yields the optimal post-disaster coordinated recovery plan for active distribution networks that considers the coupling relationship between communication and physical.Finally,taking the communication network and the improved IEEE33 node system as examples,the results of various optimization schemes proposed in this paper are analyzed to verify the superiority of the proposed strategy.
