The Framework, Standards, and Plans

AMI-Enterprise Service Definition Team

Introduction

• The service definition process (high level view)

• IEC CIM alignment

• Future Plans



The Process

Use Cases

Integration Requirements

Services

•WSDLs

•XSDs

The Process

• Logical model input & development• Identification of integration requirements• Pattern naming• Information objects• Artifact generation• Posting• Issue generation and resolution• Versioning


Logical Model Input

• IEC 61989-9 and Multispeak are the primary model inputs

• Use case contributions from SCE, Consumers Energy

• Up Coming additions: PHEV, OpenADE, OpenADR

SDO – User Group Relationship

• Iterative process• Analogy – early browser

Feedback

IEC CIM Alignment

• Consistent –some features of the spec, and in accordance, but also some additional features

• Compliant – some of spec not implemented, but what is implemented is in accordance

• Conformant – All features of spec implemented, but some additional features that are not conformant

• Fully Conformant – full correspondence between the spec and implementation.

Logical Model Development

• Standardized actors from AMI-ENT SRS

• Document business process in use cases and activity diagrams


Identify Integration Requirements

• Simply where a process flow crosses an actor boundary


Harmonize Integration Requirements

• Compare integration requirements and look for commonality:– Common actors– Common consumers– Common providers– Common information objects

• Eliminate duplicates, refine integration requirements


Patterns – Using CIM Verbs

• Pattern naming allows for both ESB and non-ESB (point-to-point) architectural assumptions

• Verbs and Information objects are based IEC 61968

• Verb examples: – Create, Created– Send, Reply

• Information Object examples:– EndDeviceAsset– MeterSystemEvent– MeterReading

<IEC Verb><Information Object> e.g. CreatedMeterReading


Artifacts & Versioning

Information objects are modeled in UML using Sparx EA. 1. IEC CIM is used as a Reference Model2. Classes and attributes are selected and transformed into

Semantic Model3. Each context folder contains an entity class diagram that lists all

entities that are used to describe an information object. 4. A model driven application tool is used to automatically generate

XSDs (implementation).

WSDL version control

An XSD is imported in a WSDL for data type definition.Two namespaces (XSD & WSDL) exist in a WSDL definition as

shown below:

targetNamespace="http://www.smartgridipedia.org/2009/03/MeterReading.wsdl"

xmlns:typeOrig="http://www.smartgridipedia.org/2009/03/MeterReading"


Notification

• Subscribe to the Listserv– http://listserv.enernex.com/cgi/wa.exe

• Send listserv e-mail– [email protected]

• When new artifacts are generated notices are sent via the listserv

• Issues with artifacts should be noted on the OpenSG collaboration site– http://osgug.ucaiug.org/default.aspx

Plans - Feedback

• Current work (if approved), is shared with IEC WG14 (Use Cases, Requirements, Artifacts)

• Begin service definition work on other approved efforts e.g. OpenADE, OpenADR
