Context:
WG14 focus and modelling requirements*

Mission of WG14



System Interfaces for Distribution Systems
The IEC 61968 series of standards

Intended to facilitate inter-application integration of the various
distributed software application systems supporting the management
of utility electrical distribution networks within a utility’s enterprise
systems environment.

Supports this integration by developing information exchange
standards using the Common Information Model (CIM), normative
message structures, additional normative parameters, and
informative recommendations and examples.
WG14 needs to address the needs of all distribution utilities:

Including the 10,000 smaller DSOs needing only one or a few of the
most common interfaces

As well as medium and larger utilities with Enterprise Application
Infrastructure projects that can make more extensive use of the
standards.
* from the WG14 roadmap
4
Context:
WG14 IRM – Interface Reference Model


Defined in IEC 61968-1
Parts 3 through 9 (shown):
 identify requirements for data
exchanges
 develop profiles derived from
DCIM (for message payloads)
 to be exchanged among two or
more business functions
(realized by products)

Part 11:
 extends base CIM to support the
above (and often other WG’s)
requirements

Part 100:
 defines implementation profiles
(JMS, Web Service), to transport
payloads within the 61968
Message envelope

If you want to join the calls:


(become a member of any CIM-developing WG)

Modelling work:
Changes tracking and process

Every WG14 CIM update release includes the following
WG14-specific files

WG14 issues spreadsheet which reflects:







the content of the latest model update
discussion in modelling calls
resolution of issues, and
all model changes within the package IEC61968
WG14 change log text file

contains summary of closed, new, commented issues, both combined and
WG14

tracks non-issue-related changes (e.g., diagrams)
overall model validation log and problems list
freshly generated IEC 61968-11 draft, from an updated
template (= continuous integration)
18
Modelling work:
Modelling priorities and timing

Priorities:

Driven by:




Needs for interoperability (IOP) tests, when planned
Those common classes that support the above
(continuous: clean-up for consistency/correctness, simplification, diagrams,
documentation)


At present, no IOP tests for WG14 planned (last were in 2011)

IEC 61968-11 Ed.3 will be based on Base CIM17 (skipped Base
CIM16); planned for 2015 or early 2016
Coordination with WG13 on final model releases is challenging –
communities have different schedules – but we all try our best to
stay in sync

19
Needs of profile documents (Parts 3 through 9, Part 13)
In WG14, we never maintain parallel models
The pointers to resources on the CIMug site relevant for WG14 work –
accessible to CIMug members

for DCIM model and document, it’s Part 11, with
all milestone files

WG14 references:
Ask for Help
http://cimug.ucaiug.org
http://cimug.ucaiug.org/HelpDesk

To find your way around


I recommend the Ask for Help
Also to file a modelling or profiling issue

for modelling, we still use spreadsheets as they let us
work independently from the network and with full set of
features that web app does not have – but this may change
in the future…
23
WG14 references:
User feedback matters

In WG14 (like in other IEC WGs), most of
experts are volunteering

It may take us time to come back to users’
requests, but we don’t forget them!

By doing early reviews of our models,
profiles and documents, we have many more
pairs of eyes that can help identify problems
early, so please do provide your feedback by
any means!
