Questions?
In 2012 the North American Institute of Standards and Technology (NIST) Smart Grid Interoperability Panel voted to include the IEC61850 standard series into the Catalogue of Standards (CoS).
“The CoS is a compendium of standards and practices considered to be relevant for the development and deployment of a robust and interoperable Smart Grid.”
IEC 61850 is also referenced in the NIST Roadmap for Smart Grid Interoperability Standards, r3.0 (Sep 2014).
These are major steps towards global application of IEC 61850.

What is the CIM and why is it needed?
The Common Information Model (CIM) is an abstract information model that provides data understanding through the identification of the relationships and associations of the data within a utility enterprise. This enhanced data understanding supports the exchange of data models and messages and increases the ability to integrate applications both within the enterprise and with trading partners. These trends go beyond exchange or updates of network models to the exchange of specific dynamic data within transactional messages in a real-time environment.
The CIM companion standards provide extensions and specifications that, when used in conjunction with the CIM models, provide a framework for the exchange of static models, transactional messages and full enterprise integration.

It ought to be remembered that there is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things. Because the innovator has for enemies all those who have done well under the old conditions, and lukewarm defenders in those who may do well under the new.
(Niccolo Machiavelli [1469-1527] from The Prince)
TECHNICAL LESSONS:- Many bugs when you are leading the
way. Factor these in. Vendors, however, are very willing to assist leaders.
- Very hard to predict milestones in technology development however existing company processes are developed with predictable milestones. This can lead to a gap in expectations and then frustration, …
- Vendor competition with standards based framework mitigates risk.
- Ratchet approach with testing works well.
CHANGE LESSONS:- A solid and carefully considered
approach is invaluable later on.
- Strong mid / high level management support is essential.
- Funding, justification and gaining support up-front all require effort.
- Prioritising discretionary funding over BAU is challenging throughout.
- Progressing delivery requires taking risk - when do you turn it ON?
BUSINESS LESSONS:- There are many side-benefits to implementing new technology:
- Improved agility- Knew techniques to solve old problems- New devices can be used with new capabilities
- New asset management frameworks (ISO 55000) and practices are emerging. Ethernet, IEC 61850, 61970, 61968 etc can greatly assist in enabling these new practices.
- Very good operational and maintenance features can be designed in to greatly assist the field in a day-to-day sense (redundant Ethernet networks, faster fault clearance, remote diagnostics and support, …).
- Provides new tools for designers to efficiently be creative with protection, control and asset management across a grid.
