3. Introduction
Distribution Management System (DMS) – system that allows the distribution operators to more effectively and efficiently operate and manage the distribution system
DMS commonly includes the following software and interfaces
User interface
Network applications
System interfaces – SCADA and OMS
DMS unique characteristics
Extremely large model size
Insertion and removal of temporary modifications
Handling of large volume of incremental updates

4. Introduction DMS benefits include the following:
Improve operational efficiency through user interface consolidation (DMS/SCADA/OMS)
Improve reliability and safety through better visualization of distribution network status and use of switching plan tools
Improve reliability indices and customer satisfaction through faster and more predictable outage restoration
Reduce penalty payments through faster outage restoration
Reduce energy losses and network operational costs with coordinated Volt/VAR management
Reconfigure control center operations dynamically
