Service Definitions A Framework For Standard Interface Development

Leveraging the Overlap CIMug UtilityAMI AMI Enterprise WG Standard Services

Key Collaboration Concept Standard building blocks are defined by CIMug –i.e., IEC working groups and other relevant industry groups such as Open Architecture Group (OAG), MultiSpeak Common industry practices are defined by the user community; the AMI Enterprise TF –by specifying how standard building blocks are used for popular scenarios with the resulting artifacts: Use cases specify required services Service definitions (WSDLs) contain the building blocks Artifacts are placed on smartgridipedia.org –Anyone may use a common industry practice or artifact.

Utility Benefits As utilities pull in the same direction, de facto standards are created; economies of scale should yield: –Improved vendor response & support –Reduced product procurement costs –Reduced effort for requirements analysis and design –Reduced risk of overlooking requirements That are expensive to retrofit later –Reduced life-cycle costs
