AMI – Advanced Metering Infrastructure

Interoperability – Why the Utility CaresInteroperability – Why the Utility Cares

Rapid and evolving technology of the Smart Grid– Need solutions that could evolve over time without costly rip and

replacement or costly upgrades Requires Integration – LOTS of integration

– Onslaught of new applications and technologies AMI, MDMS, HAN, DR, ADE, etc.

Challenges in a complex IT environment– Many custom systems, legacy system and technologies– Typically departmentally controlled – within “silos”

Need ability to govern, manage, and share resources» Both Intra-Enterprise and Inter-Enterprise

systems/applications

Key Architecture Considerations

Decoupling of end-point connections and business semantics Guaranteed delivery Managed integration End point compliance to common business semantics and syntax for

information exchange to the public (enterprise) End point compliance to service patterns (interaction patterns,

naming and structure patterns, and message exchange patterns) Minimal business logic and transformation within the integration

layer Leverage IEC TC57 WG14 Interfaces

Step 3) Service & Operation Pattern Applied

Service name: – Follows <Service pattern name>+<Information Object> (such as

“SendMeterReading”/”ReceiveMeterReading” )

Operation name: – <Operation pattern name>+<Information Object> (such as

CreatedMeterReading)
