Distribution Grid Model Data Management New Analytics and Simulations • What do those ‘future applications’ do? – Execute power flow-based simulations (network analysis functions) • What do those ‘future applications’ need? – 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.
Distribution Grid Model Data Management Challenges to Managing Grid Model Data • Distribution grid model data is complex to manage because it: – Is big – Is made up of different types of data with different update cycles coming from multiple sources – Represents one grid past & multiple grid futures – Typically is viewed as coming from a primary source: • With major consistency / completeness issues • That serves primary purposes other than providing grid model data – Must be assembled into internally consistent, ‘electrically logical’ cases
Distribution Grid Model Data Management Challenges to Managing Grid Model Data • There is only one grid • But…. different consumers want cases with – – – Different parts of the system Different types of data Different levels of detail Different system states Different points in time

Distribution Grid Model Data Management Messy Eco-System • Targets & cases • Sources – Physical network model data – Case assumptions – Engineering design • Data flows • Wide variety of tools • Many deployment patterns • No overarching data management architecture
Distribution Grid Model Data Management To Summarize So Far… • Distribution utilities will deploy new analytics and simulations • Many of which require accurate grid model data • That is difficult to manage • We have a messy starting point • With drivers that are increasing and increasingly urgent • So…. the time to do something is now "The best time to plant a tree was 20 years ago. The second best time is now. “ - Chinese proverb
