This document discusses several smart grid applications including distribution management systems (DMS), outage management systems (OMS), and distributed energy resource (DER) management systems. It provides an overview of DMS architecture and applications such as fault isolation and restoration, volt-var compensation, and load profiling. It also describes how OMS uses inputs from smart meters and AMI networks to identify outages and enable early restoration. The document references relevant IEC smart grid standards.
