As massive distributed energy resources(DERs)are integrated into distribution networks(DNs)and the distribution automation facilities are widely deployed,the DNs are evolving to active distribution networks(ADNs).This paper introduces the architecture and main function modules of an integrated distribution management system(IDMS)and its applica-tions in *** system co.sists of three subsystems,including the real-time operation and co.trol system(OCS),outage management system(OMS),and operator training simulator(OTS).The OCS has a hierarchical architecture with three levels,including the local co.troller for DER clusters,the optimization of DNs inco.porated with multi-clusters,and the co.rdina-tion operation of integrated transmission&distribution(T&D)*** OMS is developed based on the geographical information system(GIS)and co.rdinated with *** in the OTS,both the ADN and its host transmission network(TN)are simulated to make the simulation results more *** main functions of the three subsystems and their interaction data flows are described and some typical application scenarios are also presented.
