The new Distribution world Challenges/opportunities New functionalities (DER, micro-grid) New technologies (mobile, sensors, AMI, intelligent relays) New expectations (regulatory, customer) Aspirations Accurate fault location, isolation and service restoration Empower field crews with useful tools Manage and proactively leverage the benefits of DER Energy efficiency improvements of advanced Volt/VAr control Asset management to prioritize expenditures, improve reliability & reduce maintenance costs 3
Lots of types of data support the aspirations we re focusing on geospatial and grid model data Utility-owned grid asset data Field data AMI readings, load Real-time measurements, multi-second and sub-cycle Geospatial data Non-utility owned asset data Non-grid asset data Protection assets Communications assets Cyber security assets Grid model data Field device configuration data 4
We re focusing on grid model data because It underpins functions using simulations Outage management / planning Expansion planning Protection design Power quality analysis FLISR DER management Volt/VAr optimization It provides input to other critical functions Field crew enablement Generation control Effective asset management Load forecasting Visualization 5
We re focusing on geospatial because (Distribution) Grid models are derived from GIS geospatial data 161 kv 12.5 kv 12.5 kv Asset Geospatial Model Network Model 6
What is grid model data? Represents grid electrical behavior characteristics and state 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. Input to all sorts of network analysis and simulations Steady-state power flows Dynamics (sub-cycle) study runs State estimation Contingency analysis Short circuit Outage detection (unplanned) and definition (planned) Operator training simulators 7
What is grid model data? Used across Planning, Operations, Protection and Market domains Comprised of two main parts Physical network model - grid equipment electrical behavior and connectivity Operating assumptions - snapshot of the state of the grid at a moment in time (breaker states, loads, generation) Usually consumed in cohesive subsets Simulations require collections of data that make sense Simulations need only part of the model Can require simplification Typically has multiple sources Grid model data is both complex and important 8
Grid model usage There is only one grid But. different consumers want Different parts of the system Different types of data Different levels of detail Different system states Different points in time Diagram courtesy of Open Grid Systems 9

Enable management of Physical Network Model parts, which contain data representing electrical capabilities of physical grid elements Model Parts are an entity s representation of a portion of the electrical grid Model Parts fit within a framework of boundaries Model Part versions include current as-built and go back into history Potential changes to Model Parts expressed in terms of Projects 2. Provide Object Registry services, to create and maintain the mapping of network model objects among various systems 3.
