The standard series IEC 61400-25 offers five different Mappings. The Mapping according to IEC 61850-8-1 (MMS) is the most important mapping when it comes to implementations and applications.
IEC TC 57 just published a new draft for IEC TR 62357-1 Ed. 2 “Power systems management and associated information exchange – Part 1: Reference architecture” (57/1621/DC)
“The new edition provides updates and defines layered Reference Architecture to help direct longer term goals and activities, specifically to ensure compatibility of all new standards developed in TC57 by benefitting from lessons learned during development of the current standards and their application on actual utility projects as well as through application of other internationally recognized architecture standards.
This edition reflects the progress recently achieved from the international Smart Grids (SG) initiatives and the CIGRE D2.24 large system architecture vision. It also leverage the work done by NIST-SGIP, CEN-CELELEC-ETSI SGCG M490, IEC TC8 Smart Grids Roadmap, and IEC TC8 WG5, WG6, The edition also reflects the most recent editions of the TC 57 standards including IEC 61850 Edition 2 and the IEC 61968, 61970, and 62325 Common Information Model (CIM) standards.”
One of the lessons learned is that the three information models (CIM, IEC 61850 and COSEM) need some additional harmonization – a reasonable level has already be reached.
IEC 61850 has a very broad application domain and has defined many useful information models that can (and will) be “tapped” by COSEM and CIM applications.
One example that shows that IEC 61850 can be used even for schedules (de: Fahrpläne):
These schedules can be mapped from COSEM directly to IEC 61840 logical node FSCH. COSEM may be used for flexible tariffs while IEC 61850 could be used for tariffs as well as for control of switchable equipment like circuit breakers or change settings for loads or generation. The schedule LN is applied in the VHPready 4.0 specification.
More to come soon.
The Industry Alliance VHPready e.V. publishes version 4.0 of the industry standard VHPready for controlling and interconnecting decentralized energy systems to virtual power plants.
A manufacturer-independent standard, which ensures the interoperability and controllability of system components of virtual power plants, is now available for the first time. 35 member corporations [including NettedAutomation GmbH] are currently actively engaged in the industry alliance to promote the advancement of the international industry standard VHPready. The participation in the open industry alliance “Industrieforum VHPready e.V.” is based on the certainty that only a common standard will allow for a reliable, seamless and economic collaboration of all controllable components as well as their compatibility. The specification VHPready 4.0 is now available to all member corporations.
An extensive data point list constitutes the functional core of VHPready 4.0 and helps integrate different energy systems into virtual power plants using the telecontrol protocols IEC 60870-5-104 or IEC 61850-7-420. In addition to a plant park with a set of different energy systems, this data point list facilitates the integration of combined heat and power units (CHPs), wind and solar plants, heat pumps, batteries, electric heating, boilers and buffer tanks. Data points for meters and external signal contacts are also available.
At the forthcoming VHPready symposium on 12 November 2015 industry alliance members will present the first systems adapted to VHPready 4.0.

Information Technology (IT) is quite well understood by many (often young) experts. Operations Technology (OT) in the power industry is quite well understood by many (often older) experts with some tens of years experience in the use of hardware, automation and information exchange software.
These days we see the integration of Information Technology into the Operation Technology. The migration happens quite fast … and more and more experienced OP engineers are part of the “aging workforce”. This requires that new staff (IT experts and engineers) in the IT and in the OP world to learn two technologies: “IT”, “OT”, and very crucial: “More IT in OT”.
I found a very nice publication that discusses some of these issues in detail:
Click HERE for the paper “Information Technology (IT) vs Operations Technology (OT): What the C-Suite Needs to Know”
Based on my long-term experience since the early 80s with “More IT in OT” I fully agree with the need of Cross-Department Training and other needs listed in the paper:
“… considerations to improve the IT/OT rift:
In some cases of big utilities I see this already happen!
IT and OP people would benefit from our training in IEC 61850 and related standards. Be aware that even a small embedded device could support TCP/IP, higher level protocols like ftp and http(s), IEC 6070-5-104 and IEC 61850, and … it is “IT in OT”.
How do we reach more IT and OT people? Please forward this information to them …
Recent courses and discussions with experts reveal that education is THE most crucial activity to securely and reliably apply the Standard Series IEC 61850 in Power Automation Systems.

Data or device modeling is a crucial feature of IEC 61850 and IEC 61400-25. You may have seen many different approaches to explain how such a model looks like. Some five years ago I used these Russian dolls (matryoshka doll):
An IED contains a lot of “inner” objects.
![[IMG_5083[3].jpg]](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjBU8F7KY3lKS6BfDAidnyjs87k9jXMm3kji2f2x6LZw-LW6KQO3WoQSVpkuIr5dpiA_64HmVr9KerJZhYaInptmqPqYRq0e2CuME8LTQDmSnxV38xhpdHYbveLmW7DLhOEWxwAzVJkba8/s1600/IMG_5083%5B3%5D.jpg)
Today I have thought that another approach may help you to understand the IEC 61850 approach:

IEC TC 57 has published a very interesting 140 page document describing the use of IEC 61850 for distribution automation:
Draft IEC TR 61850-90-6 (57/1615/DC):
Communication networks and systems for power utility automation
Part 90-6: Use of IEC 61850 for Distribution Automation Systems
Distribution Automation and Feeder Automation Distribution Automation (DA) as a concept emerged in the 1970s to promote the application of computer and communications technologies for improving of distribution system operating performance. It is in general used as an umbrella term to describe the deployment of automation technologies for protection, control, monitoring, and operation of distribution systems.
The current document mainly describes the following functions of Distribution/Feeder Automation Systems:
A DA system may comprise up to tens of thousands of IEDs spreading over a wide area distribution network. From time to time, the new IEDs may be introduced, and the configuration of existing IEDs may need to be modified. The current configuration method for substation automation systems may need extended configuration methods. Therefore, a use case for installing new IEDs and updating the configuration of existing IEDs will also be described in this section.
In order to precise the various use-cases, the document contains sequence diagrams, e.g., for Fault Location:
The standard series IEC 61850 is THE standard for power systems.
ENTSO-E (European Network of Transmission System Operators for Electricity) wants to become “an important stakeholder in the IEC 61850 improvement process and will actively contribute, mainly through the profiling work of the IEC 61850 standard.”
ENTSO-E has just published an update on their current and future support of IEC 61850.
I very much appreciate the efforts of the European Transmission System Operators!
Click HERE for the latest news.
The electrical power delivery system is composed of many other domains that are beyond the substations in transmission systems:
IEC 61850 is about to be used in all of these application domains – to become a Seamless Information Exchange System.
Many pilot implementations and tests are underway in these domains. Usually using proprietary Information Exchange System, because the main objectives of these projects are mainly related to power system dynamics and stability – one way or the other. Later they figure out: Hey, we have a very successful project … but created many proprietary, non-interoperable Information Exchange Systems.
It is highly recommended to use IEC 61850 from the scratch! Because this is THE standard. There is usually no need to spend money and time to develop something specific for one use case.
On my radar screen I see many people starting to use IEC 61850 – users and vendors … and system integrators. All over.
Resume: ENTSO-E is just ONE of MANY efforts to apply IEC 61850.
The SCL schema is published as part of the delivery of edition 1 and edition 2 of part 6. The publication of a Technical Corrigendum to IEC 61850-6 Ed. 1 and Ed. 2 is under way.

IEC 61850-90-8 TR:
Communication networks and systems for power utility automation –
Part 90-8: Object model for electric mobility
Voting terminates on 2015-09-25
This technical report describes how current standardization for Electric Road Vehicles (EV) and the Vehicle-to-Grid Communication Interface can be linked to IEC 61850-7-420 standard for Distributed Energy Resources (DER). The technical report provides necessary background information and proposes an object model for E-mobility in order to establish an EV plugged into the power grid as DER according to the principles of IEC 61850-7-420. The basic information modeling in IEC 61850 and IEC 61850-7-420 already covers a lot of needs for the e-Mobility domain. Missing parts can be modeled as new logical nodes and data objects, which this technical report defines.
Scope
The scope of this document is to show how IEC 61850-7-420 can be used to model the essential parts of the E-mobility standards related to Electric Vehicles and Electric Vehicle Supply Equipments (IEC 62196, IEC 61851, IEC 15118) and the Power system (IEC 61850-7-420), in order to secure a high level of safety and interoperability.
Here is an overview about the topology of the logical nodes required (existing and new ones):
Standards are key for E-Mobility and many other power application domains.
