IEC TC 57 WG19 proposes CIM Profiles to JSON schema Mapping

IEC TC 57 WG is discussing the use of JSON for transferring message payload

DRAFT 62361-104:
POWER SYSTEMS MANAGEMENT AND ASSOCIATED INFORMATION
EXCHANGE – INTEROPERABILITY IN THE LONG TERM –

Part 104: CIM Profiles to JSON schema Mapping

The introduction says:

"This standard is one of the IEC 62361 series which define standards that may be used by all
Working Groups within TC57. These standards address areas of interest that impact multiple
standards and provide consistency for implementations.
This part 104 describes a mapping from CIM profiles to IETF JSON schemas and defines the
rules that CIM JSON message payloads must adhere to.
The principle objective of this part 104 is to facilitate the exchange of information in the form of
JSON documents whose semantics are defined by the IEC CIM and whose syntax is defined by
an IETF JSON schema. ..."

JSON is applicable for encoding of CIM (IEC 61968/70) message payload and - as I believe - also for IEC 61850 message payload!

By the way: The post on "IEC 61850-8-2 Versus IEC 61850-8-1" discussing the use of JSON in addition to MMS/ASN.1/BER and MMS/ASN.1/XER has been visited 2,000 times since July 5, 2019 --> or 16 times per day.

Introduction to CIM

CIM for Distribution Network Operations

IEC TC 57 has published the FDIS (57/1810/FDIS; 160 pages) of the future standard IEC 61968-3 Ed2:
Application integration at electric utilities - System interfaces for distribution management -
Part 3: Interface for network operations
Voting closes 2017-02-03

IEC 61968 provides utilities the means to supervise main substation topology (breaker
and switch state) and control equipment status. It also provides the means for handling
network connectivity and loading conditions. Finally, it makes it possible for utilities to locate
customer telephone complaints and supervise the location of field crews.
IEC 61968-3 specifies the information content of a set of message payloads that can be used
to support many of the business functions related to network operations. Typical uses of the
message payloads defined in IEC 61968-3 include data acquisition by external systems, fault
isolation, fault restoration, trouble management, maintenance of plant, and the commissioning
of plant.

This part is closely related to the Common Information Model (CIM).

OpenGridMap - Help to collect data and produce power grid approximations for CIM

OpenGridMap is a new open community that crowdsources realistic power grid data to be used for research purposes. Here you will find the tools for crowdsourcing power grid data. The goal is to create an open platform for inferring realistic power grids based on actual data. Our vision is to provide a tool to researchers and practitioners that is able to produce realistic input data for simulation studies. OpenGridMap will support the entire process from data collection to formatting grid data for various purposes. We explore innovative ways to capture data and produce power grid approximations, e.g., using smartphone apps, drones, expert classification, existing map APIs, and graph inference algorithms.

Click HERE to visit the OpenGridMap website.

The next step would be to convert the collected data into a CIM and SCL format ... it is underway for CIM (Common Information Model):

OpenGridMap: towards automatic power grid simulation model generation from crowdsourced data
By Jose Rivera, Technische Universität München

"OpenGridMap is an open source project that crowdsources realistic power grid data to be used for research purposes. In this paper, we propose an approach for the automatic generation of power gird simulation models from crowdsourced data. The proposed approach orders the crowdsourced data into a power circuit relation which is then used to produce a CIM description file and subsequently a power grid simulation model. ..." ... and I guess the modelling in IEC 61850-6 SCL (System Configuration Language) will follow soon - I am sure.

More to come as discussed during the Training Courses conducted by NettedAutomation this week in Karlsruhe:

IEEE PES published Report on "Centralized Substation Protection and Control"

The IEEE Power System Relaying Committee has published a very comprehensive report worth to be read by power system engineers dealing with substation protection and automation (partlywith focus on the  North American market):

Centralized Substation Protection and Control IEEE PES
Power System Relaying Committee Report of Working Group K15
of the Substation Protection Subcommittee
(2015-12)

Excerpt of the Introduction:
"The power grid is now more dynamic than ever before and newer tools are increasingly developed to manage the grid better. Renewable energy sources are changing power system characteristics at a time when utilities are also focusing on improving customer service and resiliency of the grid, by using advanced monitoring and control technologies....
In addition, communication technologies are advancing and related international standards are maturing to be deployed in substation environment. ... the IEEE Power System Relaying Committee has formed a working group to prepare a report describing and analyzing the state-of-the-art technologies for centralized protection and control (CPC) within a substation...
This report starts by reviewing the advancements in substation protection and control technology. Next the report describes CPC and reviews its history. Then the report reviews some of the existing
technologies that can support CPC.
Finally the report concludes that CPC technology, when appropriately applied, significantly improves the reliability of protection and control systems and the power grid at an affordable cost - with enhanced applications capability and maintainability for both hardware replacement an software upgrade."

The report gives inside views of the challenges in managing future power systems. Power systems are very complex - and will become more complex in the near future. In addition to the fact that "utilities are also focusing on improving customer service and resiliency of the grid" the utilities are quite often focusing on increasing their shareholder values ... and outsourcing many tasks. In the German "vdi nachrichten" (a very famous weekly German technical newspaper) I read yesterday an interesting statement of the new president of the BDEW (Bundesverbandes der Energie- und Wasserwirtschaft):

Translated: " ... Unfortunately the industry invests too little in view of the challenges in research and development. The German Pharmaceutical industry employs 40,000 humans in R&D laboratories.
In the energy industry there are not such research and development mechanisms. That is not because of the fact that our industry is come to a hold and does not see challenges. It is financially no more able to implement comparable research activities. We have no more enterprises, which can do that. Everyone knows nevertheless around the difficult situation of many large energy enterprises. Also normal public distribution utilities cannot advance innovative developments in the storage area."

Original: " ... Leider investiert die Branche angesichts der Herausforderungen zu wenig in Forschung und Entwicklung. Die deutsche Pharmaindustrie beschäftigt 40 000 Menschen in F- und E-Laboren.
In der Energiewirtschaft gibt es solche Forschungs- und Entwicklungseinrichtungen nicht. Das liegt nicht daran, dass unsere Branche verstockt ist und Herausforderungen nicht sieht. Sie ist finanziell nicht mehr zu vergleichbaren Forschungsleistungen in der Lage. Wir haben keine Unternehmen mehr, die das können. Jeder weiß doch um die schwierige Lage vieler großer Energieunternehmen. Auch normale Stadtwerke können bahnbrechende Entwicklungen im Speicherbereich nicht voranzutreiben."

Vendors, too, are struggling with similar challenges. We need more universities to compensate these situations. When it comes to the definition and application of information exchange systems in power or energy systems, we could be quite happy that we have the well accepted standards IEC 61968/70 (CIM), IEC 60870-5-104, DNP3, IEC 61850, IEC 61400-25, ICCP/TASE.2 (IEC 60870-6), ...

Just published: NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 3.0

NIST (US National Institute of Standards and Technology) has published the other day the third version of the NIST Framework:

NIST Framework and Roadmap for Smart Grid
Interoperability Standards
Release 3.0
September 2014

The 240 page document gives a very broad and deep inside view into the current situation with regards to crucial interoperability standards.

The list of standards (series) comprises a total of 72 entries. The following 16 (out of 72) entries refer to IEC 61850 documents:

11 – IEC 61850-1
12 – IEC 61850-2
13 – IEC 61850-3
14 – IEC 61850-4
15 – IEC 61850-5
16 – IEC 61850-6
17 – IEC 61850-7-1
18 – IEC 61850-7-2
19 – IEC 61850-7-3
20 – IEC 61850-7-4
21 – IEC 61850-7-410
22 – IEC 61850-7-420
23 – IEC 61850-8-1
24 – IEC 61850-9-2
25 – IEC 61850-10
26 – IEC 61850-90-5

The term “IEC 61850” is used some 90 times. That means: IEC 61850 is a crucial standard in North America. Other IEC standards like IEC 61968/70 (CIM) and IEC 60870-6-TASE.2 (ICCP) or IEEE standards like DNP.3 are as well included in the list.

Click HERE to download the Release 3.0 [pdf, 12.7 MB]

Further standards like IEC 61400-25 will be included soon. There are still PAPs working on some issues, e.g., PAP 16 for Wind Power.

There seems to be no serious discussion anymore if IEC 61850 and related standards are accepted – the main question is: When and How to use the “IEC 61850 Framework”.

IEC 61850-90-2 for the Communication With Control Centers

The Communication With Control Centers (from substations, power generation stations, and other sites) is usually based on IEC 60870-5-101/-104 or DNP3. The new part IEC 61850-90-2 will describe how IEC 61850 can be used for the above needs.

Experts from ERDF, Siemens, Solvay and RTE have published a paper that describes requirements, concepts and practical experiences related to the communication with control centers:

“Substation to control centre communication based on IEC 61850: requirements, concepts and practical experiences” (Cigre 2012)

SUMMARY
”Featuring object-oriented data models and a standardized configuration language, IEC 61850 represents the state-of-the-art communication standard for substation automation systems. On the other hand, the control centres increasingly promote object-oriented data models and standardized interfaces for data exchange based on IEC 61968 / IEC 61970 (CIM – Common Information Model). For the interconnection of substations and control centres the use of generic signal-oriented communication protocols i.e. IEC 60870-5-101/-104 or DNP3 is still current practice. In order to overcome the limitations of those legacy protocols in terms of data conversions, elaborated data exchanges and proprietary configurations and to foster the use of a seamless object-oriented communication, IEC TC57 is extending the current IEC 61850 specification to close the gap between substations and control centres. The paper gives an introduction into the topic, presents the relevant use cases and derived
requirements. Furthermore it discusses communication and modeling aspects in regards of the use case specific requirements. These concepts are evaluated against industrial power system operator needs. Foreseen consequences for standardization and practical realization of projects are identified.”

The report concludes:

“The experience from projects and systems in operation have proven the benefits of IEC 61850 substation to control centre communication.”

The Canadian Smart Grid Standards Roadmap and IEC 61850

“The Canadian Smart Grid Standards Roadmap” is a remarkable document that focuses on the real needs for the future of Smart Grid Technologies and standards.

It is no surprise that IEC 61850 is a key standard in this roadmap. The roadmap comes with a list of 17 recommendations on what to do in the future. Two of the six recommendations for Transmission and Distribution (T&D) systems refer to IEC 61850:

Recommendation T&D3:
To support Smart Grid interoperability requirements, the CNC/IEC should encourage the
adoption and application of IEC 61850 for the purpose of communications between
substations, between substations and control centre, and for transferring synchrophasor data.

Recommendation T&D4:
The CNC/IEC should encourage the development of guidelines and standards for utilities to
migrate from existing, commonly used technologies, to the architecture described in IEC
61850. At the same time, the CNC/IEC should recognize that the large, existing investment
by utilities in the older technologies will require gateway solutions and protocol converters
during the initial transition period.
• In addition, the CNC/IEC should encourage extending this standard to distribution
automation equipment and distributed energy resources.

Other IEC TC 57 Standards are listed as well: IEC 62357, IEC 61970 and 61968 (CIM), IEC 62351 (Security), as well as IEEE 1815 (DNP3).

DRAFT Release 3.0 of the “NIST Framework and Roadmap for Smart Grid Interoperability Standards” out for comments

The next release of the famous framework and roadmap for Smart Grid Interoperability Standards has been drafted and published for comments on April 15, 2014.

The entire 255 pages draft version of the NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 3.0 (Draft), is available online here.

"We worked closely with the European Union to harmonize the NIST conceptual model with the one the EU is developing," says NIST's Paul Boynton. "We want both models to reflect each other, which is important so that manufacturers on both sides of the Atlantic will be able to sell devices overseas."

NIST seeks comments on the draft NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 3.0.  In particular, comments on technical, editorial, or general issues.

Comments must be received on or before 5:00 p.m. Eastern Time on May 30, 2014.

Click HERE for further information on the process … how to comment …

One of the core contents deals with standards that support the vendors to build interoperable devices that could be applied in North America, Europe, and all over (!) is Table 4-1 (Identified Standards). The list grew from 34 to 74 standards from Release 2. The list refers to the following standards of primary interest in the context of this blog:

#12 IEC 60870-6-503 TASE.2 Services and protocol
#13 IEC 60870-6-702 Functional profile for providing the TASE.2
#14 IEC 60870-6-802 TASE.2 Object Models
#15 IEC 61850-1
#16 IEC61850-2
#17 IEC61850-3
#18 IEC61850-4
#19 IEC61850-5
#20 IEC61850-6
#21 IEC61850-7-1
#22 IEC61850-7-2
#23 IEC61850-7-3
#24 IEC61850-7-410
#25 IEC61850-7-420
#26 IEC61850-8-1
#27 IEC61850-9-2
#28 IEC61850-10
#29 IEC61850-90-5
#30 IEC 61968/61970 Suites
#31 IEEE 1815 (DNP3)
#64 IEC 62351-1
#65 IEC 62351-2
#66 IEC 62351-3
#67 IEC 62351-4
#68 IEC 62351-5
#69 IEC 62351-6
#70 IEC 62351-7
#?? IEC 61850-7-4 is missing – commented on it already.

15 out of 74 entries are referring to IEC 61850 standards! IEC 61850 conformant products and based systems are playing already a major role in the North American market – in the public utility world and in the power distribution in factories and production plants.

All in a sudden (as it seems to me!) managers in production facilities have figured out that electric power is very crucial for them – to save money or to increase profits.

DIN und DKE: Brücken bauen zwischen Forschung und Normung

DIN und DKE führen am 26. Mai 2014 in Berlin einen “Workshop für Forscher und Multiplikatoren zur Relevanz von Normung und Standardisierung für den Forschungstransfer” durch.

“Der Workshop wird das Thema aus verschiedenen Perspektiven beleuchten und die Möglichkeiten der Zusammenarbeit zwischen Forschung, Normung und Standardisierung präsentieren. Projekte aus den Bereichen Risikomanagement, Logistik, Energiewende und Smart Grid werden über ihre Anwendung von Normung und Standardisierung als Verwertungsinstrument berichten.”

Hier für mehr Informationen klicken.

Aus Sicht der Normenreihen IEC 60870-5-104, IEC 61968, IEC 61970, IEC 61850 und IEC 61400-25 kann auch die Forschung als Verwertungsinstrument für Normen eingesetzt werden. Für verfügbare und – vor allem – international anerkannte Normen sollte die Forschung die Ergebnisse verwerten und für Anwendungen einsetzen, die helfen, die Energiewende und Smart(er) Grids voranzubringen.

Doppel- und Dreifachnormung durch die Forschung ist kaum zielführend!

MultiSpeak – CIM Harmonization initiated at International Level

IEC TC 57 has published a new document (57/1437/CD - IEC 61968-14 TS Ed.1) trying to figure out the need for harmonization between the international standard series IEC 61968 (CIM) and MultiSpeak:

IEC 61968-14 TS:
Application integration at electric utilities
- System interfaces for distribution management - Part 14:
MultiSpeak - CIM harmonisation

Commenting period closes 2014-05-02

Please contact your national TC 57 mirror committee for a copy of the document.

I guess that more and more people all over realize the benefit of International Standards – good for utility customers. Here is an excerpt of the Introduction of the new document:

“Multiple standards that cover the same information domain present a problem for the vendor community when developing products, and for the customers that would use these products. The classic challenge becomes one of determining which standards to support or how best to support one or both standards. The problem for the customer is integrating products that follow different standards to work with each other.”

Fortunately the situation for IEC 61850 is quite different: Most of the definitions in the standard series are very unique … with little or no competition. That’s one of the reasons why the standard is liked all over.

IEC Smart Grid Tool now online

The IEC Central Office has published a comprehensive tool to facilitate identification and access to relevant standards for use cases and implementation of Smart Grid. This tool includes links to IEC standards as well as relevant standards from other organizations. The smart grid tool available at http://smartgridstandardsmap.com/ will be useful for all other IEC groups engaged in systems level work.

You will find IEC 61850 all over on that “map” – no surprise.

The Intelligent Energy Network of the Future – IT’S HERE TODAY

The project Web2Energy is one of the first projects that implements TODAY a crucial “Intelligent energy network of the future”. When the project started some years ago, the aim was far in the future. But today (early 2013): The objective of the project has already been implemented!

HSE AG (HEAG Südhessische Energie AG) invited several partners to establish a Smart Grid in their energy supply system by installation of communication links to power producers, grid terminals and the consumers.

The second year of the project was the most significant period. 4 complete work packages had to be finalized coordinated by a successful project management:

1. Application of the IEC 61850 standard for the whole communication system
2. Design und Architecture of the Information- and Communication Systems
3. W2E – Control centre based on CIM – data face (Common Information model in
   accordance with IEC 61968/70)
4. Installation of the innovative solution components and preparation of the trial
   operation.

Thanks to the involvement of experienced domain and standards experts like Dr. Michael Buchholz, Christoph Brunner, Maco Jannsson, and other experts, the project has become a big success for the realization of Smart Grids and the use of IEC 61850 and IEC 61968/70 (CIM).

It was estimated that such a high volume of approvals of new solutions in the practice of distribution networks – at it is shown in the following Figure – is first time realized worldwide. It builds an important basic for the prospective dissemination of the innovations for “Smart Distribution” … based on IEC and CIM:

Source: Web2Energy

The Website of the project provides a huge number of up-to-date papers describing the project, the reached objectives, how IEC 61850 and CIM are used … to build a real Smart Grid.

Website with links to some 40 papers and reports – many about IEC 61850.

For example the paper
Seamless data communication and management over all levels of the Power Systems
by A. Naumann, B.M. Buchholz, P. Komarnicki, C. Brunner

concludes as follows:
”In the framework of the European lighthouse project WEB2Energy with 14 European partners from 6 countries the 3 pillars of Smart Distribution are first time integrated and executed in the real operations of the 20 kV distribution network of the “HEAG Südhessische Energie AG” around Darmstadt. The complete communication loop from the network control centre down to the electric sockets of the consumers is seamless closed by the strong application and the needed extensions of the communication standard system IEC 61850. … The impact of the project findings on the further work on both standard series is considered. The results of the project have a pilot character but the servers RTU and battery boxes are brought to maturity for praxis applications. These products are open for further use.”

The IEC 61850 Stack/API from SystemCorp have been used for the IEC 61850 connectivity.

The wait for Smart Grid solutions is over – thanks to Smart people applying smart standardized solutions.

Europe: Smart Grid Standards are Here or on the Way

Just before end of 2012 a set of comprehensive documents provided by the CEN-CENELEC-ETSI Smart Grid Coordination Group (SG-CG), being responsible for coordinating the ESOs reply to M/490 (Mandate), have been published.

In 2012, the SG-CG worked intensively to produce the following reports (approved by the CEN and CENELEC Technical Boards in December 2012 - to be approved by ETSI Board early January 2013):

• Reference Architecture
• First Set of Consistent Standards
• Sustainable Processes
• Investigate standards for information security and data privacy

In addition, SG-CG produced a Framework Document which provides an overview of the activities. It describes how the different elements mentioned above fit together as to provide the consistent framework for Smart Grids, as requested by M/490.

The documents are very comprehensive and detailed! It is really surprising what experts have put together in relatively short time!! Congratulation!

Please find two small excerpts form the above listed documents:

The Smart Grid Architecture Model (SGAM) provides some kind of overview about the complexity of the European Power Grid (applicable globally) – the available standards and those that need to be defined are positioned in that model:

The model could be used as a guidline.

The CEN-CENELEC-ETSI Smart Grid Coordination Group published a “First Set of Standards” … no surprise that IEC 61850 plays a major role today and in the future. Example excerpt:

There are – of course – many other standards listed.

In the coming years there is a need for more simple and secure IEC 61850 based devices that could provide the huge amount of signals from and for the process and field zones for power generation, transmission, distribution, DER and customer premises.

The com.tom components (implementing IEC 60870-5-104, –103, IEC 61850, IEC 61400-35, DNP3, …)  are likely to play a major role.

New Work on Security for SCL, CIM, DNP3 XML-Files

XML files are used for IEC 61970 (CIM), IEC 61850, and IEEE 1815 (DNP3)
and IEEE C37.111 (COMTRADE). How can one trust that the content of an XML file for these applications has not been modified? etc.

A new work proposal has been published:
Power systems management and associated information exchange – Data and communications security –
Part 11: Security for XML Files (future IEC 62351-11)

The ballot closes 2012-07-27

This work is one of the crucial aspects of the future power systems – the various files may contain very sensitive information that has to be protected … like the protection relays and protection engineers protect the power system!!

I hope that the management takes this work very serious!

IETF Energy Management WG (EMAN) inspired by IEC 61850 and CIM

IETF EMAN, Energy Management, is an active WG that is modeling (in the MIB) a lot of power related real world objects “connected” one way or the other to a network.  SNMP is used to access this information. The objective of Energy Management (EMAN) is to provide an energy management framework for networked devices.

Networked devices could be Ethernet switches, routers, battery controller, other storages,  gateways, … more or less anything that is connected to a network!

http://tools.ietf.org/wg/eman/

The WG sees IEC 61850 as the most applicable standard to EMAN. Concepts from IEC 61850 and CIM have been reused (somehow) by the EMAN WG. A closer cooperation of the models would be appreciated by the next generation of engineers and programmers …

There is ONE real world – many models could be thought of to describe that single real world. I hope that for energy applications we will prevent to get too many models. IEC 61850 models should be used as default solution in all devices closely connected to the physical level of energy systems … different notations and protocols may be used BUT the content/semantic should be identical!

A MMXU should model the 3-phase electrical system – all over and in all models.
