SG-Network Overview• Previously started as AMI-Network with a focus on
network management.• Scope and Charter for SG-Network within UCAiug– NIST PAP 2 (Wireless standards for the Smart Grid)• Supply functional requirements for Smart Grid
Networks from a utility perspective• Define functional domains within the Smart Grid
– Create a System Requirements Specification• Provide information to SDO’s (e.g., IEEE P2030)
• Participation– Utilities, Academia, Vendors

SG-Network Overview Continued• Deliverables– Communications Requirements
• Latency, How Often, Payload size, etc– Database for using the requirements– System Requirements Specification
• Pulls all of the work together– Reference Architecture Diagram

SG-Network Output• Progress to date:– System Requirements Specification V5 complete• Key stats: • 19 payload-groupings (usecases) • 204 payloads • 500 payload-parent-sets • 7877 requirement rows (including parents and 2 rows
flagged for deletion) – Database matches requirements capture from SRS V5

Examples of work accomplished to date• Sample Actors– Smart Meter– Load Management System (LMS)
• Sample Requirement for a Smart MeterUse Case Requirement How Often Reliability Latency
Meter reading
Smart Meter shall be able send on demand read information
1 transaction per meter on demand
> 98% < 5s
Meter reading
Smart Meter shall be able to report on demand read communication failure
1 transaction per meter on demand
> 98% < 5s
Meter reading
Residential Electric Smart Meter shall be able to report when scheduled
All meters report 4-6 times per day
> 98% < 4hr
