Extension of Full-Topology Modeling in Simulator version 24

PowerWorld Simulator introduced Integrated Topology Processing (ITP add-on) in 2008 to work with full-topology node-breaker models in the power flow. PowerWorld's work over the past 15 years with dozens of companies has always interacted directly with input data structures available from the EMS models. Special features for instructing the software in tools such as contingency analysis to automatically determine breakers necessary to isolate a device have been created, as well a feature to perform the opposite task of finding presently open disconnects that need to be closed in order to return a line to service in an outage management tool.
This presentation focuses on the history of connecting software tools such as PowerWorld Simulator within the EMS ecosystem. Tools within the EMS ecosystem that we have experience connecting to include the EMS itself, outage management tools, load and generator forecasts, ICCP measurements, oneline diagram tools, and so on. These connections to other software tools required the addition of a Substation object in 2000, the introduction in 2001 of ObjectLabels for identifying devices using string identifiers that allow software tools to interact, and then addition of a designation of a BranchDeviceType in 2007 so that PowerWorld Simulator could distinguish between Lines, Breakers, Disconnects, Load Break Disconnects, and so on.
