Graphical interface of DMS to display the physical connection of a regional distribution system
As accepted by the IEEE PES DMS Task Force,
“A DMS is a decision support system that is intended to assist the distributionsystem operators, engineers, technicians, managers and other personnel inmonitoring, controlling, and optimizing the performance of the electricdistribution system without jeopardizing the safety of the field workforce andthe general public and without jeopardizing the protection of electricdistribution assets.”
DMS – Current Status and New Challenges Distribution management system (DMS) plays a critical role in control and
management of distribution systems Increasing penetration of distributed energy sources (DERs) challenges the
conventional DMS Existing technologies for control and management of DERs include microgrid
controller (MC) and DER management system (DERMS) An advanced distribution management system (ADMS) should be developed with
the integration of MC and DERMS

Conclusions
Our electric power industry experiences unprecedented changes at a stunning pace
Significant supply side changes that include continued rapid growth of renewables and changes in our thermal power generation mix may lead to changes in markets, system operations, and system planning
New consumers and new technologies may alter our demand situation significantly and lead to more uncertainty in demand forecasts
Smart grid offers both opportunities and challenges
New approaches to data management, analysis, and modeling will be needed
