2 Transmission Network Management In Support of Reliability Every tool requires its own network model, in its own format Every tool has its own users and maintainers.... /Ops Transient Analysis Expansion.. Silos are both technical and organizational Protection.... Training Simulator 2

3 Transmission Network Management Technical & Organizational Silos Silos cause: Duplicate effort Synchronization problems Consistency issues Trapped data Lots of energy invested in unproductive work Errors can go unrecognized 3

12 Transmission Network Management Support from the CIM Common Information (CIM) as foundation Began as operational model in early 1990s Support components from different vendors Became IEC Standard in mid-1990s Understood as basis for semantic model for enterprise integration Network model interoperability tests started in 2000 more than 15 to-date (bus/branch) model added in 2008 Dynamics (transient behavior) model added in 2013 Projects, outage and contingency modeling are current topics Now nearly robust enough to truly support NMM tool integration 12
