Consumers Energy’s Service Territory

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
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
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
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???
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
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
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???
