Distribution GIS & Grid Data Management Project Why GIS and Grid Data? Because grid model data underpins many future applications AMS Mobile GIS OMS Planning/ Protection Tools DERMS ADMS Because GIS data is the usual source from which grid models are derived 7
Distribution GIS & Grid Data Management Project What do those future applications do? Allow the utility plan and operate a grid that is safe, reliable and affordable (in the face of significant changes) Planning the grid Grid extension and replacement Protection systems design Optimizing third-party engagement (hosting capacity, non-wires alternatives) Operating the grid Outage detection/restoration Maintenance outage management Situational awareness Efficiency optimization It s more than Watts (or real power) It s voltage, frequency, reactive power Behavior and response over time (ramping, power quality) 8
Distribution GIS & Grid Data Management Project What do those future applications do? Execute power flow-based simulations (network analysis functions) which need high-quality network (grid) model data. Network (grid) model data: Data representing a simplified view of the electrical grid, including equipment, its electrical behavior and its connectivity, as well as its operating state at a moment in time, that is sufficient to describe a starting point for network analysis. 9
Distribution GIS & Grid Data Management Project Why is managing GIS and Grid Data a Challenge? Because Grid model data Is big (variety and volume) Must be cohesive to serve network analysis functions Is made up of different types of data Comes from multiple sources (including the field) Is needed for the past and future GIS data Often has major consistency / completeness issues Often serves primary purposes other than providing grid model data 10
Distribution GIS & Grid Data Management Project So. In summary Distribution utilities will deploy multiple applications/tools/systems Many of which require accurate grid model data That is difficult to manage A data management foundation for GIS and grid model data Reduces risk of bad data causing errors in operations decisions study results capital planning decisions maintenance decisions Saves labor wasted in duplicate entry, chasing bad data Improves timeliness of results, decisions and actions 11
