摘　　要：针对微电网发生被动式孤网事件后,进行并网模式转换为孤网模式的过程中的网架重构控制方法研究。利用有色Petri网的方法,结合Multi-Agent微源协作模型构建微电网模式控制器,弥补了运用传统方法下微电网架重构时间长的缺点。在Multi-Agent和有色Petri网的基础上引入Petri网元件状态事件表,从而大大提高了重构的效率和加强了重构过程中的监控。利用IEEE16结合微电网的改进模型进行仿真验证,验证了基于Multi-Agent和有色Petri网模型的微电网模式转换控制方法,完全适用于微电网的被动式孤网转换中的经济型重构过程。This paper presents a study on the control method of the gridreconfiguration after microgrid is passively transformed from the networking mode to the isolated net mode. In the paper, a microgrid mode controller is built by using the algorithm of multiagent system theory and colored Petri net theory to make up weakness of the longtime micro grid frame reconstruction in the traditional method. This paper introduces a component state event table on the basis of muhi agent system and colored Petri net （CPN） so that the reconfig uration efficiency and the monitoring in the reconfiguration process can be improved substantially. Finally, verification by simulation is conducted by using the microgrid model improved on the basis of IEEE16 and the simulation results prove that the method of the microgrid reconfiguration based on multiagent system and colored Petri net theory fully applies to the process of the economic microgrid reconstruction after the passive Islanding transformation of the micro grid.
