Purpose: Describe SmartCurrents IT
approach for managing application interfaces
1. The most significant NIST standard for Smart Grid
Interoperability relevant to IT applications is IEC
61968/61970 – Common Information Model (CIM)
… and SmartCurrents IT work shall comply
2. SmartCurrents shall develop an Enterprise Semantic
Model (ESM) as the basis for all application interfaces
3. SmartCurrents shall have a centralized project team
with responsibility to ensure development of ESMcompliant application interfaces
11
IT is key for smart grid through end-to-end system
integration of utility operations; CIM is focal point
of IT application interoperability standard
• “Interoperability” implies both inter-utility and intra-utility
• Most standards relate to devices, interconnection,
security, but most important to applications pertain to
semantics
Semantics: The study of
meaning; in IT, the meaning
or definition of data
12
An ESM is a definition of terms, concepts, and
data that is a corporate standard independent of
any single department or application
Also known as a Canonical
Data Model; a proven pattern
for system integration
Assertions:
• The lack of an ESM results in a
proliferation of application specific data
implementations… this is the root cause of point-to-point
interfaces and “accidental architecture”
• The CIM is sufficient to provide a basis for a
comprehensive ESM that meets the needs of
SmartCurrents and DTE Energy
• Incremental integration using the ESM to define data
messages is a successful approach for ESM refinement
and application interface development
13
An industry problem is point-to-point interfaces: each interface is a mapping
between two application data implementations

Steps that the Enterprise Services
Development team followed
• Jump start session with SISCO guided our first CIM
implementations.
• Business partners, IT leadership, and development
teams participated in CIM orientation.
• Working sessions addressed services/object exchanges.
• Mapping documents created for services outlining
attributes of CIM objects. Corresponding XSDs and
WSDLs created.
• Producer and Consumer application teams built
interfaces based on the contract.
21
As a result of the process, the Enterprise
Services Development team proposed CIM
changes
• Use case: Trouble ticket for reporting power problems.
– Developed new objects.
– Other attribute format changes.
• Left with our consultants to recommend changes with the
working groups.
22
Retrospective – What went well?
• Availability of industry experts.
• Support from CIM community.
• CIMUg engagement.
• Centralized development team for our Enterprise
Semantic Model and services.
• Well defined and documented objects.
23
Retrospective – What did we learn?
• Leadership support: getting right people involved at the
right time.
• CIM orientation provides necessary context.
• Ambassadorial approach to ensure understanding and
engagement.
24
Retrospective – What should we do
differently?
• Repository of results (document management versus
searchable web).
• Assume responsibility for entire services design earlier
(error handling, SLAs, and other details).
25
Retrospective – What still confuses us?
• No visibility into CIM working group.
• Confusion around implied duplication.
– Example: ‘ping’ a meter for its energization status.
MeterReading or EndDeviceControl/Event?
• How do we get the right people in the room at the right
time?
