BDEW veröffentlicht Smart-Grid Umsetzungs-Roadmap

Der BDEW (Bundesverband der Energie- und Wasserwirtschaft) hat am 11. Februar 2013 einen Plan veröffentlicht, in dem beschrieben wird, wie und in welchen Schritten sich Smart Grids realisieren lassen:

BDEW-Roadmap:
Realistische Schritte zur Umsetzung von Smart Grids in Deutschland

Die Roadmap kann hier herunter geladen werden [pdf, 3,6 MB].

Der Plan geht davon aus, dass die Umsetzung eher Jahrzehnte dauert als Jahre! Smart Grids werden über einen lang dauernden Marathon erreicht – Sprinter sind fehl am Platz!

In Bezug auf die nächsten zehn Jahre führt die Roadmap in der Executive Summary aus:

“… Das kommende Jahrzehnt wird hierbei in drei Phasen unterteilt:

• Die Aufbau- und Pionierphase (2012 bis 2014),
• die Etablierungs- und Ausgestaltungsphase (2014 bis 2018) sowie
• die Realisierungs- und Marktphase (2018 bis 2022).

Inhaltlich werden zehn Schritte unterschieden: Wichtige Grundlagen für Smart Grids werden durch stringente Regelungen zur Abgrenzung sowie Interaktion von Markt und Netz, die Entwicklung eines konsistenten rechtlichen und regulatorischen Rahmens, Forschung und Entwicklung sowie die Erstellung von Standards und Normen geschaffen. Diese Grundlagen müssen so schnell wie möglich entwickelt werden. Darauf aufbauend soll zum Einen die Weiterentwicklung der Infrastruktur erfolgen (Sensorik, intelligente Messsysteme, Netzautomatisierung, Energieinformationsnetz).”

Ganz wesentliche Grundlagen bezüglich Informations-Bereitstellung, –Modellierung und –Austausch sind mit den Normenreihen bereits definiert und im globalen Einsatz:

• IEC 60870-5-104 (traditionelle Fernwirktechnik),
• IEC 61850 (Informationsmanagement für alle Prozesse in der Energieversorgung),
• IEC 61400-25 (IEC 61850 für Windenergieanlagen),
• IEC 62351 (Informationssicherheit),
• IEC 6168/70 (CIM),
• …

Ein wesentlicher Aspekt bei allen Betrachtungen ist natürlich – kaum überraschend! – die Finanzierung und Rentabilität der Umsetzungen! Bei aller Nüchternheit, die in der Roadmap vorherrscht, wurde ein ganz wesentlicher Aspekt ausgeblendet: Die Notwendigkeit, hinreichend viele Ingenieure und Techniker so auszubilden, dass sie mit den vielen neuen elektrotechnischen (!!) und informationstechnischen (!) Lösungen nachhaltige Versorgungssysteme entwickeln, bauen und nutzen können!

Alleine der Aspekt IEC 61850 ist so umfassend, dass er kaum eben mal nebenbei erlernt und verstanden werden kann. Immer häufiger verstehen die Verantwortlichen in vielen Energieversorgungsunternehmen, dass für die “Kleinigkeit” wie IEC 61850 eine Schulung nachhaltige Vorteile bringt. Nur so können Anbieter und Anwender auf Augenhöhe miteinander verhandeln und zusammenarbeiten. Das habe ich diese Woche wieder während eines Trainings zu IEC 61850 bei einem großen Kraftwerksbetreiber erlebt. Ohne Ausbildung sind die Mitarbeiter (junge, ältere oder auch alte Ingenieure) dem Wohl und Wehe der Anwender ausgeliefert!

Es wäre sehr zielführend, wenn der BDEW die Ausbildung in Richtung IEC 61850 (und anderer Normen) forcieren würde! Vor wenigen Jahren war das Thema IEC 61850 weitgehend tabu!

IEC 61850 in the Joint EURELECTRIC-EDSO Smart Grid Position Paper

The “Union of the Electricity Industry” (EURELECTRIC) and “European Distribution System Operator for Smart Grids” (EDSO) have assigned a very high priority to the application of IEC TC 57 standards, e.g., IEC 61850, CIM, IEC 60870-5/-6, IEC 62351, … in the paper “DSO PRIORITIES FOR SMART GRID STANDARDISATION”.

End of January 2013 they have published a comprehensive position paper on the standardization for smart grids:

Access the paper “DSO PRIORITIES FOR SMART GRID STANDARDISATION” [pdf, 590 KB]

A key clause puts IEC 61850 on a high priority (excerpt of one example):

3.3. Extended field data modelling standards (IEC 61850) to support demand response, DER and VPP

”While the IEC 61850 standard was originally addressing applications and communications within the substation, recent work is being undertaken for extending its applicability to distribution automation applications integrating field devices located outside the substation fence. With its object oriented structure, IEC 61850 can provide comprehensive and accurate information models for various components of distribution automation systems, as well as an efficient solution for this naturally multi-vendor environment.
Some typical applications include: Volt/Var Control (VVC), Fault Localisation, Isolation and Restoration (FLIR), Outage Management System (OMS), Distribution State Estimator, Distributed Generation and Demand response Management, Load Forecast and Modelling (LFM), and other.
IEC 61850 is the only international standard for substation automation which is open for future application. Currently IEC 61850 is extended for use outside substations. The use cases of the different distribution automation concepts need to be considered in the information data models. Therefore the IEC 61850 data models shall cover all distribution automation objects. IEC 61850 allows an open and flexible design and operation of communication networks. IEC 61850 not only provides a protocol for communication but is a whole new concept for naming and configuring substations and power grids.
The normative definition of logical nodes for DER is necessary for new smart grid appliances because process devices have to be described in such logical nodes for information exchange. Therefore it is important that current valid logical nodes in process protocols are not subject to change in the further standardisation process and to enable new devices to seamlessly comply with existing protocols without proprietary vendor solutions.”

Another key issue is the support of System interoperability operability testing!!

“A system interoperability testing method including conformance testing, "profiles" and "test use cases", should be provided by the end of 2013”

More to come – keep tuned to this blog.

TÜV SÜD organizes IEC 61400-25 (IEC 61850) Interoperability Workshop on 18.-19. March 2013

The USE61400-25 user group focuses on minimizing the interoperability risks of communication between devices or/and systems claiming conformance to the IEC 61400-25 standard. In order to fulfill this goal, interoperability workshops are held periodically. The next workshop will be held on 18.-19. March 2013.

This interoperability workshop is free of charge for all current USE61400-25 members. Nonmembers are cordially invited to join the workshop as well. To subscribe for the interoperability workshop please return the signed registration form to the testing team [Word doc].

The interoperability workshop will be held at
TÜV Süd, Ridlerstr. 65, Raum E005
80339 München, Germany

18th and 19th of March 2013.
18th March: 13:00 – 18:00
19th March: 9:00 – 12:00

Please note that the standard IEC 61400-25 is based on IEC 61850 in general and on IEC 61850-8-1 (MMS Mapping) in particular. The MMS Mapping is – to my knowledge – the solution that is used in most applications. The interoperability test is thus also a kind of an IEC 61850 interoperability test. as can be seen from the registration form:

One of the supporting turbine manufacturers that offers IEC 61400-25 connectivity is REpower. In a paper Repower published recently they referred to IEC 61850 as the basis for IEC 61400-25. See also blog post on the paper.

IEC 60870-5-104 and IEC 61850 for Vattenfall’s VHP-Ready (Virtual Heat and Power Ready) Version 3.0

Vattenfall Europe Wärme AG has published Version 3.0 (October 2012) of their technical specification for virtual power plants: VHP-READY – Virtual Heat & Power Ready. This version comprises a complete profile of models for use of both standards. A detailed list of Signals respective Logical Nodes and Data Objects has been specified.

The new version specifies the use of IEC 60870-5-104 and IEC 61850:

• IEC 60870-5-104 or IEC 61850 / 61850-7-420 (two options)
• TCP/IP
• SSL/TLS
• SNTP/NTP

Download the complete specification version 3.0 [German only, pdf, 670 KB].

This specification is exactly what the market needs to do: Specify in some level of details what is required for a typical application!

Congratulation to Vattenfall to lead the market (to a great extent) in preparing and presenting a publicly available specification of a profile for virtual power plants based on two international Standards: IEC 60870-5-104 and IEC 61850 (IEC 61850-7-420).

IEC 62351 added to SGIP Catalog of Standards

Thirteen new standards have been added to the SGIP’s Catalog of Standards (CoS) , bringing the total number of standards currently in the CoS to 56.  The newly added standards include also IEC 62351:

IEC 62351 Parts 1 – 7
The scope of the IEC 62351 series is information security for power system control operations. The primary objective is to undertake the development of standards for security of the communication protocols defined by IEC TC 57, specifically the IEC 60870-5 series, the IEC 60870-6 series, the IEC 61850 series, the IEC 61970 series, and the IEC 61968 series.  Another objective is to undertake the development of standards and/or technical reports on end-to-end security issues.

• IEC 62351-1:  Communication network and system security – Introduction to security issues
• IEC 62351-2:  Glossary of terms
• IEC 62351-3:  Communication network and system security – Profiles including TCP/IP
• IEC 62351-4:  Profiles including MMS
• IEC 62351-5:  Security for IEC 60870-5 and derivatives
• IEC 62351-6:  Security for IEC 61850
• IEC 62351-7:  Network and system management (NSM) data object models

Note also this paper on TLS security issues (published the other day).

The Transport Layer Security (TLS) protocol aims to provide confidentiality and integrity of data in transit across untrusted networks. TLS has become the de facto secure protocol of choice for Internet and mobile applications. DTLS is a variant of TLS that is growing in importance.

That is why security experts should read the paper.

IEC 61850-Why all the Hype?

A report written by two ABB experts asks “IEC 61850-Why all the Hype?”.

“This question was on the mind of the operations manager of a municipal utility when he visited the ABB Smart Grid Center of Excellence (CoE) in Raleigh, N.C. He was considering developing a smart grid substation standard design using IEC 61850. ... He wanted to determine whether the IEC 61850 standard is all hype or could meet their requirements.”

The report concludes: “Our visitor was satisfied with the performance and ease of access to real-time data enabled by the IEC 61850 architecture. He said that the engineering definition and structure defined in the standard
will simplify engineering and integration for the technical team. He was convinced that building a system on the foundation of the IEC 61850 standard would more than satisfy the goals of increased operational efficiencies, maximized system interoperability and support for implementation of advanced applications, which will ensure long-term system viability.”

Aging Infrastructure drives Use of IEC 61850

The aging infrastructure in the electric power delivery system drives the application of IEC 61850 conformant products. One example is the the application of optical sensors in Mexico: “ … the last decade, over two hundred failures of conventional instrument transformers occurred in the Mexican Transmission Electric System. … Since 2004, four projects were developed about optical current transformers (OCT´s) to identify its advantages and shortcoming … demonstrating that it is now a reality a protection scheme using optical instrument transformers and Digital relays interconnected using a network according to IEC 61850-9-2.”

The project was also presented at the DistribuTECH 2013 last week in San Diego:

Lessons learned from first multivendor 400 kV transmission line protection scheme using optical CTs and IEC 61850-9-2 process bus protection relays

by James Ariza - Megger
Carlos Melendez - CFE
Nicolas Juarez – CFE
Rodolfo Colon – IIE

The presentation concludes:
The first multivendor 400 kV transmission line protection scheme using an
IEC 61850-9-2 digital network for optical CT´s and digital protection has
been successfully installed and is in operation since May 2011.
Correct operation and interoperability have been demonstrated during the
commissioning tests as well as real fault on the line.

A paper on the same project was presented at Cigre 2012 it could be downloaded [pdf, 586 KB]

Second and third day of DistribuTECH in San Diego

The second day was similar compared to the first day. I have talked about IEC 61850 and IEC 61400-25 to many domain experts that showed serious interest in my training services. Most had been quite surprised that there is a global interest in IEC 61850.

When I showed them the list of the 175+ training sessions I conducted over the last 10 years, they were really amazed.

The documents I have handed-out at the exhibition are now available for download:

General Information about IEC 61850, Smart Grid, products, … [pdf, 4.1 MB]

Training information, program example, list of references [pdf, 3.0 MB]

Standards information, List of Logical Nodes, UML examples [pdf, 850 KB]

Brief description of Lite Gateway IEC 61850 / IEC 60870-5-104 [pdf, 480 KB] 

At the end of the day several interested people came by that wanted to learn more about IEC 61850 – they will be served today (Thursday, January 31, the last day of the DistribuTECH 2013.

The third day was quite busy. Several domain experts in the power distribution world contacted me to get the latest information regarding to IEC 61850.

Summary: This event was the most busiest and successful DistribuTECH I have visited since 2009! The situation regarding IEC 61850 is changing quite fast: vendors of various products for substations and distribution systems need to offer IEC 61850 connectivity even for IEDs that have been on the market for some time. One of the easiest and most convenient solutions seems to be the Beck IPC Chip that could be implemented on a small PCB and mounted in the existing housing – it’s that easy:

More details on the chip, its architecture and IEC 61850 support could be found in the fist document (General …) listed above.

First day of DistribuTECH in San Diego

This year’s DistribuTECH exhibition seems to have a lot more booths than before. The huge hall has 34 rows full of large and small booths. When you walk the floor you see many products that provide IEC 61850 connectivity.

A lot of people I spoke to are in the process of developing IEC 61850 connectivity or are planning to do so in the near future.

The UCAIUG booth 1648 was visited by may people from all over:

The annual meeting of the UCAIUG IEC 61850 group focused on testing. The experiences show that IEC 61850 conformance tests are an absolute must for IEDs that claim to be conformant. But: The focus on testing will definitely move towards interoperability testing.

TÜV SÜD reported about their experience with testing. They are a strong supporter of interoperability testing. TÜV SÜD could play a major role in defining the needed requirements and rules and they could be a major organization to setting up test facilities.

ENTSO-E’s activity to get involved in the quality improvement process of the standard and conformant products is welcome throughout the industry.

ENTSO-E has published a Research and Development Roadmap for the next 20 … 30 years. Communication infrastructure is one of the key elements in the future power delivery system.

IEC 61850 and other protocols on embedded Platform

Beck IPC has launched a new website for their ready-to-go modules Com.Tom supporting many protocols to build a variety of applications that need to communicate through appropriate channels. The new website is now open in English as well:

http://www.com-tom.de/products.php?l=en

The core component of these boxes is the Beck IPC Chip that runs many protocols. Stack/API libraries for Protocols like IEC 60870-5-104, IEC 61850, Modbus, CANbus and many others are available and tested in applications.

See References:

More to come soon.

These IEDs allow to implement various applications that require IEC 60870-5-104 or IEC 61850 connectivity or gateways in a short-time-to-market development. The protocol stacks come with an ready-to-go API. The APIs are using the same approach of Calls and Callback functions to be used by application software.

Use of IEC 61850 for Electrical Systems Monitoring and Control in the Oil and Gas Industry

Laurent Guise and Patrick Montignies both from Schneider Electric Industries (Grenoble, France) have discussed the use of IEC 61850 for Electrical System Monitoring and Control Systems in the Oil and Gas Industry. The results can be found in a nice paper some years ago.

“Crucial industrial sites such as for Oil and Gas plants are requesting more and more monitoring and control of their electrical installation to increase the electricity availability of their process while optimizing the cost of operation.

While willing to implement an Electrical Monitoring and Control System (EMCS), users face the issue of choosing the right communication technology.

By the way an emerging technology – IEC 61850 – appears on the market. This technology promises real interoperability, while offering unprecedented capabilities for reducing the wiring and increasing the installation agility. Are all these promises a reality? What would be the most pragmatic way for taking the maximum benefits of this new technology while minimizing the risk? The object of this paper is to make a point of technology maturity, to identify the real benefits, but also some potential drawbacks.”

In the conclusion the authors state: “Is there a value to choose IEC 61850 for EMCS application? … there are definitely a lot of reasons for considering positively the usage of IEC 61850.”

Access the complete paper on IEC 61850 for Electrical System Monitoring and Control [pdf]

Today, a few years after the paper was published, we can state that the situation has been improved since then. Especially the availability of mature products for monitoring and control of any kind of processes and equipment installed in the many electrical systems make it easy these days to implement IEC 61850 in short time to market – and for a reasonable price.

To build a Gateway between IEC 61850 and any typically used RTU protocol is as easy as riding a bike.

Lite Gateway IEC 61850 to IEC 60870-5-104 at DistribuTECH in San Diego

NettedAutomation will demonstrate the following lite Gateway between IEC 61850 (process level with various I/Os) and IEC 60870-5-104 (RTU) at the DistribuTECH next week (29.-31. January 2013) in San Diego (booth 1648):

The components (HW and SW) can be used to build many useful topologies:

• Gateway IEC 61850 (client) to IEC 60870-5-104 (slave) – as shown in the picture
• Gateway IEC 60870-5-104 (master) to IEC 61850 (server)
• Gateway many serial links to IEC 60870-5-104 (slave)
• The two software packages from SystemCorp running on these platforms (IEC 61850 stack/API and IEC 60870-5-104 stack/API) can be used in any combination and with many communication channels (Ethernet, GSM GPRS, WiFi, Bluetooth, …).
• The IEC 61850 server could – of course – be accessed directly by a remote client.
• Other protocols are available.

The box in the middle is a Com.Tom Radio 2.0 and the right box is a development kit DK61.

The following signals (data model) will be demonstrated:

I look forward to meeting you at the DistribuTECH in San Diego (CA) next week.

If you need help in using these lite components, please let us know.

Is IEC 61850 held hostage by interoperability issues?

NO! There are in some cases minor issues that may have some impact on interoperability. In general: Interoperability at the communication level is provided!

Farel Becker and Andre Smit just published a paper with the title: “IEC 61850 feeds grid protection and control”.

They ask: “IEC 61850 has been under scrutiny recently with claims of interoperability. But, are these claims valid? Can IEC 61850 improve and enhance protection and control system design today, or is it held hostage by interoperability?”

They conclude: “The functions and features, namely the use of GOOSE messages, made available today by the IEC 61850 standard can be used to greatly improve current substation and other application designs and help realize new methodologies to better protect, control and automate the smart electrical grid of the future. This, in itself, far outweighs perceived interoperability issues and keeps the industry on track to eliminate copper wires and expand system functionality and capabilities.”

Well written.

It is really crucial to be serious about Security!!

IEC 61850 Extensions for Fault Passage Indications (FPI)

First Committee Draft (38/436A/CD) of IEC 62689-1 accepted by end of 2012: Current and Voltage sensors or detectors, to be used for fault passage indication purposes - Part 1: “General principles and requirements”.

This standard will introduce a dedicated (extended) IEC 61850 namespace (based on existing and new Logical Nodes and Data Objects) to support integration of FPIs into power utility automation. In addition, it defines different profiles of communication interfaces to support the different cases of usage of these FPIs. Some of these cases of usage relies on the “concept” of extended substation, which is intended as the communication among IEDs through IEC 61850 located both along MV feeders and in the main substation, for most sophisticated FPIs version (for smart grids applications, for instance). Then such profile may not be limited to FPI devices, but may embrace features needed to support extensions of these substations along the MV feeder connected to the main substation themselves.

The scope of this standard is to define the minimum requirements for Fault Passage Indicators (FPIs) which are devices able to detect faults, on networks from 1 kV up to 52 kV, providing indications about their localization (upstream or downstream the FPI’s location) or about the direction of fault current. The localization (upstream or downstream) or the direction of the fault current may be detected directly from the FPI and/or from a central system using information from more FPIs and/or considering the features of the feeder/network where the FPI is installed (for instance in case of over-currents in radial operated networks without GD or in case of phase to earth faults in solid earthed radial operated systems).

Part 2 of the standard series will contain the dedicated (extended) IEC 61850 namespace (based on existing and new Logical Nodes and Data Objects).

IEC 61850 as Digital Interface for Instrument Transformers

The CDV (Committee Draft for Voting) of IEC 61869-9: Instrument Transformers - Part 9: “Digital interface for instrument transformers” is out for ballot and comments until 2013-03-01.

This document will replace and extend the so-called “9-2LE” that defines the first profile (or subset) of IEC 61850 for voltage and current sensors (Merging Units).

The new standard is based on experience gained since the publication of “9-2LE”. There are a lot of new details in the configuration and description of the information models defined – in order to reduce the number of options.

The IEC 61869-9 standard will (when published):

• Replace IEC 60044-8 digital solution.
• Provide a product standard for instrument transformers with a digital interface according
  to 61850; similar to what IEC 62271-3 is doing for switchgear.
• Be backward compatible with the UCA International Users Group’s Guideline for Digital Interface to Instrument Transformers Using IEC 61850
• Use IEC 61588-Ed2 for time synchronization, with an option for 1PPS.
• Be applicable for AC and DC measurements.
• Be using 100 Mbit/s or 1 Gbit/s Ethernet.
• Specify 4.800 digital output sample rate with 2 sets of values per message (2.400 messages/s) for general measuring and protective accuracy classes, regardless of the
  power system frequency.
• Specify 14.400 digital output sample rate with 6 sets of values per message (2.400 messages/s) for quality metering accuracy class, regardless of the power system frequency.
• Specify 96.000 digital output sample rate with 1 set of values per message (96.000 messages/s) for DC instrument transformer applications [likely to using high speed Ethernet end-to-end].

Proposed conformance classes are (with detailed PICS in the draft):

• class a: the minimal set of services required to transmit MU data using sampled values;
• class b: class a capabilities plus the minimal set of services required to support GOOSE
  messages;
• class c: class b capabilities plus the implementation of the IEC 61850 series’ information
  model self-descriptive capabilities;
• class d: class c capabilities plus services for file transfer and either one or more of
  unbuffered reporting, buffered reporting, or logging.

IEC 61850 Extensions for Control Systems in Thermal Power Plant

Part 90-13 of the IEC 61850 series is under way. The draft document specifies the additional common data classes, logical nodes and data objects required for the use of IEC 61850 in Thermal Power Plants.

Some years ago the power plant control systems started to connect to the power plant internal power delivery system for the power loads inside a power plant.

In a whitepaper dated 2007 Joerg Orth, ABB AG, Mannheim, published an interesting white paper on the connection between the two systems based on IEC 61850: “Future power plant control - Integrating process & substation automation into one system”

“Today’s power plants are highly automated. All subsystems of large thermal power plants can be controlled from a central control room. One subsystems area is the electrical auxiliaries for the unit transformer, the grid connection, excitation, synchronization, generator/unit protection, auxiliary transformers, HV-, MV- and LV-switchgear. In the past, these electrical devices were all hardwired to the DCS and I/Os. To this day, horizontal communication between electrical devices is still hardwired. In the last decade, serial communication protocols were introduced. Unfortunately, standardization of these protocols went in different directions. Today there are several standards on the market. … The future is talking IEC 61850 providing solutions for seamless integration concepts for new and refurbishment projects.”

These days the development goes a step further: IEC 61850 extensions for power plant internal (!) control functions. This is a new approach for internal control functions, because it has an impact on the power plant control system – not only on the internal and external substations.

The current draft of IEC 61850-90-13 defines, for example the following specific Logical Nodes for Thermal Power Plants:

EJCL	Power plant joint control function.
ESEQ	Start / stop sequencer.
ESPD	Speed monitoring.
EGTU	Gas turbine production unit.
EUNT	Thermal unit operating mode.
ESTU	Steam turbine production unit. For some data objects see below
EBCL	Boiler control function.
…	…
MENV	Environmental data
MGAS	Gas-flow measurement.
MOIL	Oil-flow measurement.
MSTE	Steam-flow measurement.
MEXH	Exhaust Gas Mass Flow.
…	…

Draft settings of the LN ESTU (Steam turbine production unit):

Turbine type (steam, gas, oil)

Turbine rated speed [s-1]

Turbine moment of inertia J [kgm2]

Maximum transient overspeed [s-1]

Runaway speed [s-1]

Rated power in turbine mode [MW]

Rated flow in turbine mode [kg/s]

High pressure inlet maximum pressure [Pa]

Intermediate pressure inlet maximum pressure [Pa]

Low pressure inlet maximum pressure [Pa]

High pressure control valve rated oil pressure [Pa]

High pressure control valve rated closing time [s]

Intermediate pressure control valve rated oil pressure [Pa]

Intermediate pressure control valve rated closing time [s]

Low pressure control valve rated oil pressure [Pa]

Low pressure control valve rated closing time [s]

As can be seen from this example, IEC 61850 arrived at the modeling and communication of the power plant internal control system level. More to come. The draft has been written by the IEC TC 57 WG 18. It will be discussed at its next meeting in March 2013 in Nice (France). WG 18 has already published the LNs for Hydro Power Plants (IEC 61850-7-410 Ed2).
