The Use of Geographic Data Views to Help With Wide-Area Electric Grid Situational Awareness

The paper presents the use of geographic data views (GDVs) to help improve large-scale electric grid situational awareness for power flow and time-domain simulations. GDVs are electric grid display objects whose location is dynamically determined from geographic information embedded in an electric grid model. The paper provides examples using a 2000-bus and an 82,000-bus synthetic electric grid to show how GDVs can be used to help provide wide area understanding of values such as generator outputs, switched shunt values, voltages, and transmission line flows. It also shows the application of force-directed layout of GDVs and GDV summary objects.
