Boundary Device Management Tool for Distribution Network Model Resource Center in Advanced Distribution Management System

The operation of active distribution network (ADN) will take into account more uncertainties, flexibility and diversity provided by the distributed energy resources and flexible loads. The optimization of ADN should be based on a panoramic distribution network model. An architecture of advanced distribution management system is proposed, which the distribution network model resource center is the core layer to integrate the models from the EMS, DMS and EMMS, and to provide model services for the advanced functions. With respect to issues in terms of ambiguous boundaries, information missing or overlapping between multiple models, a boundary device management tool based on IEC 61970 and IEC 61968 CIM is designed, whose main functions include searching boundary devices, overlapping information analysis, model merging and model partitioning.
