English Version of Vattenfall’s “VHP READY – Virtual Heat & Power Ready” available

Vattenfall Europe Wärme AG (Berlin, Germany) has published the famous specification “VHP READY” for information exchange in virtual power plants based on IEC 60870-5-104 respectively IEC 61850-7-420.

In order to integrate renewable energies into the power supply system successfully and economically, ways must be found to store and control them. The Virtual Power Plant, which stores energy in the form of heat, is a promising approach to solving this problem. With this technology, modern heating systems can also help to integrate renewable energies into the power supply cost-efficiently and accelerate the “Energy Transition”.

Data transmitted between a plant and the central control system via IP networks are encrypted either according to the IEC 60870-5-104 standard or the IEC 61850 series of standards (IEC 61850-7-420 in particular). Time synchronization is via SNTP/NTP. The following protocols are used for communication:

• either IEC 60870-5-104 or IEC 61850 / 61850-7-420
• TCP/IP
• SSL/TLS
• SNTP/NTP

Download the specification 3.0 in English [pdf]
Download the specification 3.0 in German [pdf]

The approach used in the specification is exactly what needs to be done for many other applications domains: define the profile to be implemented in such a detail that no or just very few options are left!!

The specification needs some more details to be published: the complete details of the information model as an SCL file. Currently the models are partly specified in SCL … the LNs and DOs are just listed in a table. The next version will have more details. And it is very likely that other resources like PV … will be included in version 4 as well.

Congratulation to Vattenfall for this promising approach!

IEC 61850 for “Facility Smart Grid Information Model”

The Draft BSR/ASHRAE/NEMA Standard 201P “Facility Smart Grid Information Model” has been published for Public Review in July 2012.

The draft standard uses a good part from IEC 61850 models (IEC 61850-7-3, –7-3 and -7-420). The paper document has been derived from a UML document.

The purpose of this standard is to define an abstract, object-oriented information model to enable appliances and control systems in homes, buildings, and industrial facilities to manage electrical loads and generation sources in response to communication with a “smart” electrical grid and to communicate information about those electrical loads to utility and other electrical service providers.

The IEC 61850 community should have a look at this draft in order to make sure that the models used form IEC 61850 are referenced - the maintenance of the models in IEC TC 57 should automatically adopted by the standard 201P in the future. This would allow to get a consistent set of models.

PV Power to (de)stabilize the European Power Delivery System?

One swallow does not make a summer – But 100.000 do. One PV system on a roof in the nineties did not make a smart grid based on renewable resources. But due to the growth of renewable resources like PV the power delivery system changes a lot. Usually today the PV inverters do automatically frequency disconnection.

ENTSO-E the “European Network of Transmission System Operators for Electricity” noted in a letter to Commissioner Oettinger of the European Commission that too many “swallows” are flying somehow “uncontrolled” – flying alone … not being aware what’s going on around them … not seeing the system (!):

“This letter is to brief you on a security of supply issue arising from the automatic frequency disconnection settings of installed photovoltaic (PV) panels in some European countries and to request your support in encouraging the national Regulatory authorities in impacted countries to facilitate the timely implementation of remedial actions.

Due to the interconnected nature of the transmission system until such remedial actions are implemented the synchronous Central European power system is at increased risk to significant frequency deviations of a magnitude that would generate a widespread loss of supply.

In several European countries, connection standards applicable to photovoltaic panels and other distributed generation have been or are still specifying that the panels automatically disconnect from the grid whenever the system frequency reaches 0.2 or 0.3 Hz deviations from the required normal value of 50.0 Hz.

Current information from our Member TSOs, including for example Germany and Italy, indicate that the significant growth in photovoltaics in recent years has resulted in a PV installed capacity (with such settings) approaching 25 000 MW. At these levels there is clearly a risk of an instantaneous generation loss far in excess of the 3000MW generation loss „ride-through‟ design limit for the Continental European system. …”

Click HERE for the letter from ENTSO-E [English, pdf]

Ok, what to do now? Act! There are many actions needed to get CONTROL over the system in the future system based on many distributed resources! One aspect is to change limits … but more important is the control of the power resources.

A group of IEC TC 57 WG 17 is working on a very crucial part of IEC 61850: Draft IEC 61850-90-7 TR – “Communication networks and systems for power utility automation – Part 90-7: IEC 61850 object models for photovoltaic, storage, and other DER inverters” (57/1155/DC).

Major PV inverter manufacturers and other experts have drafted the above document.

Crucial aspects covered by 90-7 (in addition to IEC 61850-7-420 – DER) are:

7. DER management functions for inverters.

7.1 Immediate control functions for inverters
7.1.1 Function INV1: connect / disconnect from grid
7.1.2 Function INV2: adjust maximum generation level up/down
7.1.3 Function INV3: adjust power factor.
7.1.4 Function INV4: request real power (charge or discharge storage)
7.1.5 Function INV5: pricing signal for charge/discharge action

7.2 Modes for volt-VAr management
7.2.1 Var management modes using volt/VAr arrays
7.2.2 Volt-VAr mode VV11: normal energy conservation mode
7.2.3 Volt-VAr mode VV12: maximum VAr support mode
7.2.4 Volt-VAr mode VV13: static inverter mode
7.2.5 Volt-VAr mode VV14: passive mode.

7.3 Modes for frequency-related behaviours
7.3.1 Frequency management modes
7.3.2 Frequency-watt mode FW21: high frequency reduces active power.
7.3.3 Frequency-watt mode FW22: constraining generating/charging by frequency (see diagram below)

7.4 Dynamic grid support during abnormally high or low voltage levels
7.4.1 Dynamic grid support mode TV31: dynamic grid support during abnormally high or low voltage levels
7.4.2 Example of dynamic grid support capabilities.

7.5 Functions for “must disconnect” and “must stay connected” zones
7.5.1 “Must disconnect” MD curve
7.5.2 “Must stay connected” MSC curve

7.6 Modes for watt-triggered behaviours
7.6.1 Watt-power factor mode WP41: feeding power controls power factor

7.7 Modes for voltage-watt management.
7.7.1 Voltage-watt mode VW51: voltage-watt management: generating by voltage
7.7.2 Voltage-watt mode VW52: voltage-watt management: charging by voltage

7.8 Modes for behaviours triggered by non-power parameters
7.8.1 Temperature mode TMP
7.8.2 Pricing signal mode PS

7.9 Setting and reporting functions
7.9.1 Establishing settings DS91: modify inverter-based DER settings
7.9.2 Event logging DS92: log alarms and events, retrieve logs
7.9.3 Reporting status DS93: selecting status points, establishing reporting mechanisms
7.9.4 Time synchronization DS94: time synchronization requirements

Example (without further explanations):

7.3.3 Frequency-watt mode FW22: constraining generating/charging by frequency:

It is expected that this part IEC 61850-90-7 is one of the crucial parts of IEC 61850 for the stability of the future power delivery systems all over.

It’s “PV summer time” – there are millions of PV inverter installed (most of them are not controlled … just “flying” around.

The Power Systems are quite comprehensive … and complex!

Electro Mobility, Substation Automation and IEC 61850

The basics for the infrastructure needed for the Electro Mobility have already been standardized – the electrical power delivery system: generation – transmission – distribution of electric A.C. power. The standardization of the electrical system has a long tradition. The monitoring, protection and control of electric power is automated in many higher voltage levels. There are mainly five international standards used all over: IEC 60870-5-10x for telecontrol, IEC 60870-6 TASE.2 for inter-control center communication, IEC 61850 for substation automation and protection, DER, Hydro power plant monitoring and control, IEC 61400-25 for monitoring and control of wind turbines, and IEC 61131-3 for a open PLC programming language.

These standards cover most of the needs for information modeling, information, system configuration, information exchange, and function programming for substations and power generation.

Mr Roland Bent (CEO of Phoenix Contact) stated the other day in the Open Automation magazine that EV charging stations are small low voltage substations. He is absolutely right! It is crucial to understand that the above mentioned standards are applicable in all voltage levels. What is the difference of a three phase Y-system for 400.000 V and 400 V? The multiplier of factor 10**3. There is no need to re-event the wheel again.

Here is an excerpt of Mr Bent’s statement in German:

“Ein noch wesentlich größeres, neues Marktfeld findet sich in der Infrastruktur für Elektromobilität. Ladestationen für Elektrofahrzeuge sind kleine Niederspannungsschaltanlagen mit all den Komponenten und Steuerungskonzepten aus diesem Bereich. Sie müssen auch informationstechnisch in die intelligenten Netzstrukturen integriert werden und stellen neue Anforderungen an IKT-Strukturen, zum Beispiel im Bereich der Abrechungssysteme. Auch hier werden wieder Kompetenzen und
Know-how aus der Industrieautomation benötigt.”

Utility Grid Communication Network in Electric Vehicle Charging Infrastructure takes IEC 61850 into Account

The IEC TC 69 (Electric road vehicles and electric industrial trucks) has proposed a new project to define "Utility grid communication network in electric vehicle charging infrastructure" - 69/176/NP. The New work proposal refers to IEC 61850 as standard that should be considered as base standard. It could be assumed that IEC 61850 has already a lot of definitions that can be re-used by the experts that will define this standard. It is likely that IEC 61850-7-420 has already many information models defined for that application.

Voting is open between 2010-09-17 and 2010-12-17

SGIP Fall Meeting
September 15, 2010, St. Louis, Missouri
12:30 to 3:00 PM

This Cross-PAP issues session is your chance to participate in discussions on coordinating consistent object models and information exchange requirements for different generator types (e.g., wind turbines, hydro power plants, PV systems, and storage) across multiple domains (consumer, distribution, and transmission). This session is expected to aid in producing consistent object model requirements (where possible) being developed for example by PAPs 7 and 16 for IEC 61850-7-420 (DER), IEC 61850-7-410 (hydro) and IEC 61400-25 (wind). The consistent generator control, monitoring and protection requirements are to be coordinated and combined with requirements of other PAPs including 3, 4, 9, and 10. There are several areas in which the various application domains highly benefit from consistent information models, consistent information exchange and security steps. The interface between power generation and the control center and between aggregators and distributed generators are obvious examples. This session is intended to provide overviews of and to initiate coordination of activities required to develop consistent object models for different generator/storage types across different Smart Grid domains.

IEC 61850 Workshop at Hydro Quebec, Montreal, Canada

The IEC TC 57 WG 17 (DER) will meet in Montreal, Canada, on September 27-29, 2010. Experts from WG 17 invite interested experts from the power utility domain for a one day workshop on IEC 61850. 

Date and Time: September 30, 2010, (Thursday); 8:30 -15:00 h
Venue: Hydro Quebec, Montreal, Canada

A couple of WG 17 members have suggested to organize an extra day for information dissemination of the results reached by WG 17 and the ongoing work. Another objective is to discuss common modeling issues with experts from other domains like hydro, wind, PV, ... one issue for discussion is the remote monitoring and control of power generation (example of IEC 61400-25-2).

On Thursday (September 30) there will be an open presentation of crucial aspects of the standard IEC 61850 and especially of IEC 61850-7-420 and a demonstration of the latest development of the “IEC61850@CHIP” and first experiences with the small platform especially for PV systems.

The chip provides the complete IEC 61850 (IEC 61400-25) MMS, GOOSE and Sampled Value communication stacks. The stacks and the device data models are configurable by a standard SCL File (IEC 61850-6) uploaded to the chip. The stack provides a simple API for IEC 61850. Applications can be developed in C/C++ and IEC 61131-3. The focus shifts from communication (especially MMS) programming to your applications and system and device configuration.
The chip supports SSL and other security standards.

The development of affordable standards-conformant interfaces for distributed energy resources can now be shortened to days or weeks - from months and years. The range of all crucial Beck IPC products (IPC@CHIP®s, modules, Development kits, …SCL Designer, Application programming using the simple stack API) will be presented and discussed during the workshop. This extra workshop will be conducted by Karlheinz Schwarz.

The workshop is open to everyone interested in the presentation and demonstration free of charge. Breakfast and lunch breaks are on the attendees; drinks will provided.

You may attend and invite other experts that may be interested to attend.
Please let Karlheinz Schwarz (schwarz@scc-online.de) know who will attend in order that we can confirm a seat. The number of seats is limited to 20 seats.

Adoption and Update of Wind Power Plant Communications Standard 61400-25

The NIST PAP 16 team (Wind Plant Communication) will gather use cases and requirements from wind industry stakeholders with a focus on those requirements associated with integrating bulk wind assets into wind plant operation and utility command and control systems. Special attention will be given to those use cases and requirements that differ from those developed by the IEC TC 88 61400-25 working group to quickly identify the gaps that are preventing ubiquitous application of the standard in the US. The PAP Team will seek out recent ARRA funding awardees involved in wind plant projects to ensure that their requirements are discovered and they are made aware of the existing portfolio of standards available.

The PAP 16 team will provide specific recommendations to the IEC TC 88 working group responsible for maintaining the 61400-25 standard to address the gaps identified.

Click HERE for the PAP Proposal [WORD document].

The standard IEC 61400-25-2 (Wind) mainly extends the information models of IEC 61850-7-4, 7-410 (DER) and 7-420 (Hydro). All objects of all four standards build a huge set of standard information models. ALL models ca be used on generic IEC 61850-8-1 compliant communication stacks. Even new models not yet standardized but defined by anybody (!) can be configured and run on compliant communication stacks - the extended models just have to follow the well defined name space concept.

So, if you need a Logical Node, e.g., LN FIZL = Fizzli Puzzli, for your Puzzli application: just define the Data Objects you need: Fipu1, Fipu2, ... of common data class SPS (single point status) ... and you are done. Define the corresponding SCL file and run it with a communication stack. You need to know what the LN and its Data Objects mean - and you have to bind it to your Puzzli application. Here is how a client sees the corresponding server:

The value of the name space of the LN nameplate FIPU1.EX.LPL.LnNs is "NIST-PAP16_2010-06-26_Fizzli-Puzzli-LN" - indicates that this is a standard conformant Extension (Functional Constraint FC=EX).

The LN instance in SCL notation is:

<LN lnType="FIPU_1" lnClass="FIPU" inst="1">
  <DOI name="LPL">
    <DAI name="lnNs">
      <Val>NIST-PAP16_2010-06-26_Fizzli-Puzzli-LN</Val>

      <Val>This is a NIST specific extension of the IEC 61850/61400-25 information model.</Val>
    </DAI>
  </DOI>
</LN>

DataTypeTemplate for new LN class:

<LNodeType id="FIPU_1" lnClass="FIPU">
  <DO name="Fipu1" type="SPS_0" />
  <DO name="Fipu2" type="SPS_0" />
  <DO name="Fipu3" type="SPS_0" />
  <DO name="Fipu4" type="SPS_0" />

  <DA name="d" bType="VisString255" fc="DC" />
  <DA name="lnNs" bType="VisString255" fc="EX" />
</DOType>

So, NIST or any other organization can quickly identify the gaps in the information models and define any model that is needed for the application of the standard in the US (!!). Most use cases known so far may be implemented by extending the models or defining new models - private models, models defined by any other organization, or by IEC or ANSI or ...

IEC 61850 in the IEC Smart Grid Standardization Roadmap

IEC has published the "IEC Smart Grid Standardization Roadmap" for public access. It is a "technically oriented reference book which represents the standardization requirements" for Smarter Grids.

The core standards identified in this framework are mainly:

• IEC/TR 62357 – Framework of power automation standards and description of the SOA (Service Oriented Architecture) concept
• IEC 61850 – Substation automation and beyond
• IEC 61970 – Energy Management System – CIM and GID definitions
• IEC 61968 – Distribution Management System – CIM and CIS definitions
• IEC 62351 – Security

IEC 61850 is referenced more than 150 times in the Roadmap.

German E-Energy Roadmap for Smart Grid published

The 70+ page Roadmap of the German E-Energy Projects and German Standardization organizations has been published the other day.

The Roadmap contains many recommendations on how to use existing standards and how to improve or extend those standards. According to the German Federal Minister of Economics and Technology "it is the task now to ascertain the extend to which these approaches can be implemented". He wishes the Roadmap many readers and users.

The Roadmap refers some 50 times to IEC 61850 - IEC 61850 is one of the very crucial standards for Smart Grids. IEC 61850 is likely THE standard that will be used in many domains outside the electrical world. The new edition of the information models (IEC 61850-7-4) contain many new Logical Nodes like STMP (Supervisory of temperatures) that can be used wherever a temperature is to be monitored for limit violation (alarm and trip): in a factory, building, power plant, ship, ...

IEC 61850 is a single standard for many application domains. More to come. Stay tuned.

First Release of the NIST Framework and Roadmap for Smart Grid Interoperability Standards

Commerce Secretary Gary Locke today (2009-09-24) unveiled an accelerated plan for developing standards to transform the U.S. power distribution system into a secure, more efficient and environmentally friendly Smart Grid and create clean-energy jobs.

The NIST Draft Publication "NIST Framework and Roadmap for Smart Grid Interoperability Standards Release 1.0 (Draft)" published by the Office of the U.S. National Coordinator for Smart Grid Interoperability" is the result of thousands of working-hours of hundreds of smart people from many states and countries.

Smart Grids will be build on standards. The most crucial standards are required for the following areas:

• Demand Response and Consumer Energy Efficiency
• Wide Area Situational Awareness

NIST found that the market has reached already consensus on 16 standards. After review of this list, there are now 31 standards understood as crucial for the smart grid. Many crucial IEC standards like standards from IEC TC 57: IEC 60870-6 (TASE.2), IEC 61850, IEC 61969/61970 (CIM), IEC 62351; IEC TC 65: IEC 62541; other committees: ISO/IEC 15045, ISO/IEC 15067, ISO/IEC 18012, ... are members of the list of the 31 standards!

The experts identified some 70 gaps in the list of standards. 14 gaps have been identified as MOST CRUCIAL to be solved:

"For each, an action plan has been developed, specific organizations tasked, and aggressive milestones in 2009 or early 2010 established. One action plan has already been completed. The Priority Action Plans and targets for completion are (in bold = impact from/on standards of IEC TC 57):

1. Smart meter upgradeability standard (completed)
2. Common specification for price and product definition (early 20I0)
3. Common scheduling mechanism for energy transactions (year-end 2009)
4. Common information model for distribution grid management (year-end 20I0)
5. Standard demand response signals (January 2010)
6. Standard for energy use information (January 2010)
7. IEC 61850 Objects / DNP3 Mapping (2010)
8. Time synchronization (mid-2010)
9. Transmission and distribution power systems models mapping (year-end 20I0)
10. Guidelines for use of IP protocol suite in the Smart Grid(mid-year20I0)
11. Guidelines for use of wireless communications in the Smart Grid (mid-year 2010)
12. Electric storage interconnection guidelines (mid-2010)
13. Interoperability standards to support plug-in electric vehicles (December 2010)
14. Standard meter data profiles (year-end 2010)
