IEC is one of the front-running bodies for providing standards to manage Smart Grids, such as CIM and IEC 61850. However, standardization in such an area is so wide with so many different actors, that this is also raising new challenges to IEC, such as having top-down standardization process, or in providing and maintaining domains cross-cutting data modeling activities. This presentations examines what vendors and standardisation bodies are currently doing independently and collaboratively to achieve a multi-vendor network.

Main recommandations to reach
interoperability at information level
●Pre-requisite : Ensure that the IEC 61850 standards is offering an
accurate and consistent semantic level layer
● This task falls under the standardisation role
● This work has already been mostly achieved thanks to the UML modelling
assessment
●  first outcome are visible under the Tissue process
● The Amendment 2.1 of IEC 61850 will make this much clearer
●Then Profile the use of IC 61850 per systems
● This task requests an indepth involment of standard users
●All market actors need to contribute
● Caracterize the system under focus (architecture, application domain)
● and then per systems
●Identify the (largest) minimum set of functionalities (Use cases)
●Derive from it the minimum data set
●Derive from it testing cases

Conclusion
●Reaching the interoperability at information, thanks to IEC 61850 is a
real new market challenge
●Interoperability at information level needs to target first
a per-system approach
●It requests the involvment all users of the IEC 61850 standard
●IEC needs to evolve in order to host these new activities :
● Per system functional requirement (Use Cases)
● Per system data profile (data will have a new status « required », beside
being kept « mandatory/optional »)
● Per system testing cases
