Open AMI Network

This document provides a comprehensive overview of the Advanced Metering Infrastructure (AMI) network, focusing on data collection systems, interoperability challenges, and maintenance use cases for electric and gas meters. Key areas include the integration of various systems, differences in proprietary communication technologies, and recommendations for enhancing the lifecycle management of AMI components. It outlines specific functional requirements for maintenance, identifies viable points of interoperability, and evaluates existing and new use cases to improve network performance and reliability.

  3. Consumers Energy’s Service Territory • 1.8 Million Electric Meters • 1.6 Million Gas Meters • 1 Million gas meters in non Consumers Energy’s service territory

  4. AMI – Observations • Differences between systems • Proprietary Communication Technology • System logging and auditing • Device registration – device dependant • Collector • Meter • Substation metering • Other (smart grid devices, etc) • Network management interfaces • Outage reporting • Troubleshooting • Monitoring performance • System configuration and upgrades

  5. AMI – Observations (Cont.) • AMI communication vendors are not interoperable for maintenance and management • Meter • Collector/Access Point/Mesh Gate/Take out point/Cell Relay/Tower Gateway Base Station/ Base Station • HAN ESP interface managed and implemented different between vendors

  6. AMI-Network TF Proposal • Define the devices and well defined points of interoperability within the AMI network for maintenance • Define the benefits of interoperability between AMI network maintenance components to utilities • Sharing backhauls • Gas AMR meters • Water AMR meters • Hybrid AMI systems • Point to Point and mesh and PLC

  7. Proposed TF Scope • Evaluate existing Maintenance Use Cases • Define New Maintenance Use Cases • Define System Functional Requirements for AMI meters to the AMI head end for maintenance/lifecycle purposes • Identify areas within an AMI network that are viable for maintenance interoperability • Scope is outside of OpenHAN and the Zigbee/Homeplug efforts • Input from the Group???

  8. Evaluate Existing Use Cases • SCE use cases • S1 AMI system recovers after power outage, communications or equipment failure • U1 Utility installs, provisions and configures AMI system • U2 Utility manages end-to-end life-cycle of the meter system • U3 Utility upgrades AMI system to address future requirements • Other Utility use cases • AMI Vendor use cases

  9. Define New Use Cases • Focus on maintenance life cycle related activities for the meter thru the head end system • Avoid HAN use cases with the exception of the AMI Communication interface with the ESP • IP/3rd party gateways

  10. Functional Requirements • Create a SRS (system requirements specification) similar to OpenHAN’s efforts • Derive requirements from the use case review • Focus on the AMI head end to the meter from a network maintenance perspective • Input from the group???

  11. Schedule • Meet via teleconference every 3 weeks • Meet at every UCA face to face meeting Questions/Comments? Next Steps?
