2. IEC TC57 WG14 Developing IEC 61968
Focus is to describe the information exchanges between systems (i.e. A2A and B2B) related to distribution operations
Defines integration between a variety of systems including network management, outage management, work management, asset management, SCADA, metering, call handling, …
IEC architecture specification is transport independent
XML used to format message payloads
Messages defined using nouns and verbs
Recognizes request/reply and publish/subscribe messaging paradigms

4. IEC 61968 Documents Part 1: Architecture Part 2: Glossary
Part 3: Network Operation
Part 4: Network and Asset Management
Part 5: Operational Planning and Optimization
Part 6: Maintenance and Construction
Part 7: Network Extension Planning
Part 8: Customer Inquiry
Part 9: Meter reading and Control
Part 10: Systems External to, but Supportive of, Distribution Management
Part 11: Common Information Model (extensions)
Part 12: Use Cases

5. IEC 61968
Extends the package of the CIM, where the core CIM is defined by IEC
Integration defined using XML messages
Messages have a header and a payload
Header identifies a noun and a verb
Payload uses CIM-derived type definitions as described using XML Schema
Can be used for SOA implementations

6. CIM Packages

7. CIM Extensions
Modeling of electrical distribution, extending Wires package
Added package to CIM:
Assets
Consumer
Documentation
Work
ERP_Support (leverages OAG)

8. Use Cases

9. IEC Messages
Message has header, with optional request, reply and payload sections
Header includes information such as a verb, noun, timestamps, revision, source, replyAddress, …
Supports request/reply, publish/subscribe and point-to-point messaging

10. IEC Messages

11. Message Verbs Request/Reply: CREATE CHANGE (UPDATE) CANCEL CLOSE
DELETE
GET
SHOW
REPLY
Publish/Subscribe:
CREATED
CHANGED (UPDATED)
CANCELED
CLOSED
DELETED
SUBSCRIBE
UNSUBSCRIBE

12. Example Message Nouns NetworkDataSet NetworkChangeSet LoadDataSet
OperationalRestriction
SafetyDocument
SwitchingSchedule
OutageReport
TroubleTicket
PlannedOutage
OutageNotice
Work
Schedule
AcessPermit
OneCallRequest …

13. Steps in Defining Messages
Generate XML Schema complex types from the CIM (once)
Develop use cases
For each use case, identify message sequences in terms of verbs and nouns
For each message define XML Schema, identifying necessary payload content in terms of references to CIM complex types

14. Customer Meter Data Sets

15. Status
Last meeting held October 2005 in St. Louis, attended by 19 persons
Next meeting to be held January 2006 in Switzerland
Parts 1 and 3 have been completed, but will be updated to reflect agreed use of XML Schema
Most work is currently being done on parts 4, 6, 9 and 12
Need to get WG14 CIM changes stabilized into base CIM
