Application Information May 2010 Application Information Q: we further clarify the Smart Grid applications? A: Huge amount of information developed by Open SG Example: http://osgug.ucaiug.org/UtiliComm/Shared%20Documents/SG-NET%20PAP%20work-in-progress/Diagrams-wip/SG-NET-diagram-r0.5e.pdf Bruce Kraemer, Marvell

May 2010 Listing of pertinent use cases In order to create a list of functional requirements for the Smart Grid, an exercise was performed to list all pertinent use cases that involve network communication. Sources for this information include the Southern California Edison Use Cases, Grid Wise Architectural Console use cases, EPRI and others. Use cases from all of these sources were selected based upon a network requirements basis. From this research the following high level use cases have been identified http://osgug.ucaiug.org/UtiliComm/Shared%20Documents/Interium_Release_3/SG%20Network%20System%20Requirements%20Specification%20v3.doc Bruce Kraemer, Marvell
