The development of smar t grids is essential for Europes energy policy. In order to integrate large-scale renewable

energy generation, sustain security and resilience of the networks and realise energy savings we need an expanded and

modernised network that makes best use of all the intelligent technologies available. European standards for smart grids,

smart meters and charging interfaces with electric vehicles are a prerequisite to allow our industry to invest in and make

use of smart grids. We need them as soon as possible: the longer it takes, the more investments are delayed.

At the European Council of 4 February this year, the Heads of State invited the Member States, in liaison with European

standards bodies and industry, to accelerate the work with a view to adopting technical standards for smart grids and

meters by the end of 2012. As stressed in the Commissions Communication for the deployment of Smart Grids of 12 April,

standardization of interfaces, the implementation of security by design and data privacy principles in relevant devices are

key issues for the development of smart grids, metering and the interface with electric vehicles.

The European Commissions mandates to the European Standards Organizations for smart meter standards were

issued in March 2009 and for electric vehicles standards in June 2010. Building on the consensus achieved among all

stakeholders participating in the Smart Grids Task Force, the Commission issued a mandate for standardization of smartgrids by the end of February 2011 (1). The standardization process for smart grids should moreover coordinate and benet

from the ongoing work on smart meters and on charging interfaces for electric vehicles. Thus, the reference architecture

for smart grids in Europe and an essential set of standards is expected to be issued by the end of 2012.

This report is an excellent guide to identifying existing standards and the gaps still in place as well as to the work ahead of

us to meet the mandates objectives. Acknowledging the recommendations contained in the report as the product of close

co-operation of all stakeholders jointly with the European Standards Organizations, I am also condent that future work

towards their implementation will continue in the same collaborative and inclusive spirit.

I would like to thank all the participants involved in the execution of these mandates for their commitment to this work, andwould like to emphasise the importance of a timely delivery of the work ahead.

Let us contribute to the smart grid standards that Europe needs so urgently.

Executive summary Europe is committed to the 20-20-20 targets to reducecarbon emissions and to secure energy supply. Energyefciency and renewable energy are seen as key to reach thisgoal. Both measures call for changes in our energy supplysystem leading to smart grids as key enablers for the requiredinnovation. To promote this transformation the EuropeanCommission has taken a number of actions including amandate on standardization.

Standardization of smart grids is not business as usual. Thehuge number of stakeholders, the necessary speed, the manyinternational activities and the still changing solutions makeit a difcult task for the European Standards Organizations(ESOs). This report investigates the status of smart gridsstandardization in Europe. It does not duplicate the extensive

work already done in other regions. Its main focus is theorganization of standardization in Europe.

The present version of the report focuses on the smartelectricity grid, keeping it aligned with the scope of theEuropean Commissions Smart Grids Task Force ExpertGroups 1, 2 and 3.

High level recommendations:

Use a top down approach The dif ferent applications to be deployed over time

need to t together. This can only be assured by strongcoordination.

Build up a exible framework of standardsMarket business models, players and technical solutionsare still changing. A exible model or architecture mustbe available to map services and use cases.

Agree on a European set of use casesEstablish a single repository of use cases to systematicallyidentify existing and future standardization needs.

Align with international standardsCooperate with international and relevant national smartgrid standardization activities. Base European standardson existing international standards and promote Europeanresults to the international level.

Dont reinvent the wheelReuse existing mature standards whenever appropriate.

Adapt the organization and processes forstandardizationSmart grids are a system issue rather than a productissue. The CEN/CENELEC/ETSI Joint Working Group

will promote this approach in close collaboration andcooperation with the existing TCs and structures.

The aim of the report is to provide a strategic report whichoutlines the standardization requirements for implementingthe European vision of smart grids, especially taking intoaccount the initiatives by the Smart Grids Task Force of theEuropean Commission. It provides an overview of standards,current activities, elds of action, international cooperationand strategic recommendations. After an introduction tothe political and technical background of smart grids inEurope and the current standardization activities aroundthe world, and a description of the scope of the report andthe procedure followed in its development, the report goeson to state general recommendations addressed to theEuropean Standards Organizations. The current status ofstandardization in cross-cutting and domain-specic topicsis addressed in detail. The report concludes with the nextsteps to be taken.

In summary, the report identies thus the necessary stepsto be taken and proposes recommendations concerningstandardization of smart grids. A prioritization of actions stillneeds to be performed and the content will be inuencedcontinuously by external events. This is especially true forthe standardization mandate. The content and spirit of themandate need to be included in later versions of the report.It is therefore planned to revise this document regularly. Itis now up to all of us to play an active part in the furtherimplementation and development of standardization of smart

grids in Europe in order to put the vision into practice. A largeamount of standardization work has already been done and avast set of important and mature standards is already in place.Smart grids implementations based on these standardscan already start from this level and from the work alreadyin progress. Reduction of the known gaps and overlapsis underway. In addition, longer term improvements arenecessary to provide a coherent and future-safe frameworkand processes for standards development. The reportaddresses both aspects.

This paper presents an overview of recommendations forsmart grid standardization in Europe. The complete reportfrom which these recommendations are the summary isavailable from the web-sites of the European StandardsOrganizations:

Recommendations for smart gridstandardization in Europe

G-1 Further development of the report This repor t should be fur ther developed with regardto the focal topics identied, in cooperation with thecorresponding professional groups and stakeholders.

Topics such as energy storage, security of supply andmicro-grid may also be included.

G-2 International standards as a basis forpromoting EU industry Standardization of smart grids must be based on existinginternational work, to avoid reinventing the wheel, toaccommodate solutions which are already standardizedand applied for practical purposes and to secure theinterests of European manufactures who are operatingglobally. This document recognizes that work and thereforebuilds upon the globally recognized smart grid standardsas identied in the report.

G-3 Speed of implementation reuse

existing systems There are already a number of quite advanced initiativesaround the world which are described in the report. Inorder to secure European interests in the implementationin Europe and around the world existing mature domaincommunication systems should be used. The ESOs shouldfurther standardize necessary interfaces and productrequirements and must avoid standardizing applicationsand solutions. The focus must be on standard developmentaccording to the R&D and deployment priorities of the EUgiven in the Smart Grids Task Force reports, the ETPand the SDD.

G-4 Concentrate on future proofstandardization

Smart grids is a highly dynamic technical eld. Standardsmust therefore be generic and open to include futuredevelopments from R&D and pilot projects. It is thereforerecommended to concentrate on generic standardswhich exibly mirror market needs and technologicaldevelopment.

G-5 Build up a SINGLE repository for smartgrid use cases

The descriptions of functionalities / use cases representan important basis for the further work, including that on

standardization. It is therefore recommended to collectuse cases as a base to start detail work on standards.Supply this repository with at least

- the M/441 set of use cases,

- active liaisons with all European smart grid projects,

- the EG1 to EG3 reports of the Smar t Grids Task Forceof the European Commission, and

- experience from of the national committees.

Check if the re-use of use cases coming from othercountries or regions may lead to single worldwide use-case denition.

Dene the methodologies: templates, classication,organization, harmonization of use cases, publication, etc.

G-6 Adapt standardization processesDene the processes needed to match the lack of maturityof many smart grid applications. As stated in the EG1report, smart grids deployment will be a continuouslearning process and standardization should propose aclear set of processes to cope with this learning process.For instance, use an electronic form of communicatingstandards in order to enable seamless integration ofstandard data models. Dene open and transparent qualityprocesses attached to smart grid standards, covering thewhole life cycle of such standards, including how to collectissues, to treat/x issues, and then to validate and test.

G-7 - Relationship between legislativerequirements and standardization A proven concept, described as New Approach and further

developed as New Legislative Framework (NLF), has beenthe legislative denition of essential requirements. Relatedto the legislative document (e.g. directive or regulation),harmonized standards from the European StandardsOrganizations (ESOs) describe further technical details.Following the harmonized standards it can be assumedthat the essential requirements of the legislative documentare fullled (presumption of conformity).

For the system approach of the smart grid no essentialrequirements from legislation are currently available. Therelationship between the standards produced by theESOs under the standardization mandate and future

legislative initiatives at the European level needs furtherconsideration in due course, once the lat ter are dened.

O-1 Extend timeframe and scope of JWGSmart Grids

The JWG scope and duration should be adapted to thewider needs of further tasks, coordination of responsesto an EC mandate and a further investigation of the everchanging environment in the smart grids area.

O-2 Marketing of ESOs work on smart grids

ESOs must highlight their work on the markets, andpromote the work already done on international andvarious regional levels. This is necessary to maintain the

high level of inuence on international standardizationand therefore on solutions. Funding of the externalrepresentation of the ESOs should be investigated asinternational activities indicate that the roles of the USand Asia are growing due to high public funding of the

respective standards organizations. Although this mightconict with the traditional role of European standardizationthe short time frame for action in order to participate withinthe ongoing debate at international level and the need tostandardize in areas where R&D still is needed, publicfunding might be justied for some stakeholder groupslike R&D institutes or SMEs. Any solution should be basedon the co-operation with national standards organizationsand their experts and expertise.

O-3 Mandates in relation to smart gridsConcerning the different mandates that are or will be

issued in the context of smart grids, consistency andcoherence must be ensured by the Technical Boardsof CEN and CENELEC and by the ETSI Board by takingaccount of and building on the results of the work carriedout already as far as possible.

Term-1 : Harmonization of glossariesEstablish a process for harmonizing smart grid vocabularyover different domains.

PPC-1 Electronic Data models Align glossaries as much as possible with Electronic DataModels ( TC 57/SC 3D).

Ref-1: Conceptual ModelContinue work on a Conceptual Model which describesthe major stakeholders and their interactions taking intoaccount the work of the Smart Grids Task Force.

Ref-2: Functional ArchitectureDevelop, possibly based on the IEC/TC 57 model, aFunctional Architecture that takes into account all thegeneric, global aspects of smart grids as well as all theEuropean specicities, in particular those outlined inthe Conceptual Model. This model must accommodatethe harmonization of potentially different architecturesproduced during the denition of several smart gridapplications.

NOTE - This model should be fed back to global standardsdeveloping organizations

Ref-3: Communication ArchitectureDevelop a Communication Architecture to take intoaccount the large variety of network and connectivityscenarios involving communications interface.

Ref-4: Security Architecture

Expand the work done in the European CommissionSmart Grids Task Force, in particular the EG2 Report, tocreate a security architecture also taking into account aconformity assessment approach whenever applicable.

Ref-5: Consistent Information Model

Ensure that the Information Architecture is both relying onprecisely identied standards and also that the consistencyof Information Model is guaranteed by an appropriatemechanism for re-aligning separately developed (and

possibly diverging) models.

Ref-6: Create a Reference Architecture teamwithin the Smart Grid Joint Working Group

The role of this team would be to set up the scope andwork methods for the work associated with the Reference

Architecture, and make sure that at least some of the majorviews (Conceptual Model, Functional, Communication andSecurity Architecture) are in line with the deadlines of theStandardization Mandate.

Sys-1: Adapt ESOs to handle top-downsystem approachesSet up adequate bodies and sustainable processes tomanage smart grid top-down system approaches and therelationship with the existing TCs in charge of developing

standards. These processes should cover the overall lifecycle of standards from upstream requirement denitions,down to interoperability testing. Provide an incrementalway of proceeding and maximum exibility for addressingunknown future usages.

Establish the conditions for managing European smartgrid use cases in a consistent way: shared rules, sharedtemplate, shared list of actors while keeping alignmentwith the IEC SG3 Smart Grid Use Cases Initiative.

As soon as possible, feed the TC 8X with these top-downsmart grid use cases, to be taken into account by ad hocstandardization bodies. Ask the European projects to feed

the standardization process with European use casesand elaborate the set of European smart grid use cases.

Sys-2: Initiate Smart Grid Data modelactivity Initiate activity on a Smart Grid Data model within agroup reporting to JWG.

Sys-3: Initiate Smart Grid SystemManagement and security activity Initiate Smart Grid System Management and securityactivity within a group reporting to the JWG.

NOTE - Information security aspects are addressed in aset of dedicated recommendations.

Sys-4: Check comprehensiveness ofstandards towards interoperability Check the coverage of selected standards againstsemantic, behaviour, conformance testing and ll gapswhen needed.

Com-1: Further develop power/distributionline communicationFollow the recommendations of the SMCG Technical Report, which already contains a work plan for CENELEC/TC 13to integrate different protocols with the existing standards.

Most EMC guidelines and standards start at frequenciesabove 150 kHz, which could lead to interference betweendomestic appliances and PLC devices operating belowthis range. For frequencies lower than 150 kHz the EMCguidelines/regulations should be developed. For PLCcommunication the use of the frequency range up to540 kHz should be specied, subject to protecting existingusers of these frequencies for radio communication andother purposes.

For broadband PLC we recommend that where applicableand no alternative standard inside ETSI/CEN/CENELECcan be found the IEEE P1901 should be taken into account.

Work with the ETSI PLT TC to evaluate the use of ITU-T PLCNarrow band Orthogonal frequency-division multiplexing(OFDM) G.9955.

Com-2: Harmonize activities on datatransport technologiesDevelopments made by ETSI and the data communicationrelated IEC and CEN/CENELEC activities within IEC andCEN/CENELEC should be mutually coordinated. Theservice capabilit ies dened by ETSI should be integratedwith the smart grid related application protocols mentionedin the data communication interfaces section of the report.

Com-3: Align the work on intra-domainstandards between the AMI and other SmartGrid subsystems

Further work on Use Cases and standards regardingthe interfaces between the AMI and other smart gridapplications (such as EV charging and DER metering)should be aligned under the new Smart Grid Mandate,in cooperation with the SMCG.

6 Standardization recommendationsregarding data communication interfaces

Sys-5: Systematically address systeminteroperability Pave the way for implementing step-wise approach tointeroperability.

Sys-6: Create quality process for smart gridstandardsDene open and transparent quality processes attachedto identied smart grid standards covering their wholelife cycle, including answers on how to collect issues, to

treat/x issues, to take into account new market needsand then to validate and test, including the compatibilitywith former releases.

ISec-1 Ensure system level informationsecurity requirements are covered in allrelevant standardsFast incorporation of system level information securityrequirements (for all data protection classes andinformation security levels) into

I. product, solution and service standards of all sphereof action domains;

II. sphere of action domain-specic organizationalstandards for market roles participating in smartgrids, according to their responsibilities, and functions

provided.Ensure consistency between those and sustain state ofthe art SGIS and DPP by synchronizing all standardswith changing guidance on system level requirementsfor SGIS and DPP.

ISec-2 Smart grid functions and usecases require binding to SGIS and DPPrequirementsFor several data protection classes (SG-DPC) legalrequirements exist and require the appropriation ofthe SG-DPC, i.e. personal data, control data, logging.

Therefore, the concept of SGIS is to provide theenablement for bonds between

- the use cases which describe the intended utilizationof data as well as

- the usage rights based on obligations and limits of itsusage and its required specic information security level(who, when, why, what data is generated, processed,stored, transmitted, erased) and on justication derivedfrom contractual/regulatory frameworks).

This will need a denition for all specic SG-DPCs andSGIS-SLs. The concept is to obligate the use case writingexperts to identify ALL data models used in the function oruse case (these describe the data usage and justicationof the specic usage). The data model repository will needto include the specic data protection classes (SG-DPCs)for every single UML data model. The information securityexperts will need to specify the appropriate informationsecurity level requirement (SGIS-SL) for each singleSG-DPC.

It is recommended that ESOs provide interlinkedrepositories to achieve the required bonds.

ISec-3 SGIS-SL and SG-DPP upgrade andsynchronization requirements

There are 2 distinct independent areas with changing

dynamics along the pathway to implementation of smartgrids

- Innovation dynamics in smart grid function and usecase denitions describing the changing OperationalModel of smart grids and the data models used

- and in dynamics in SGIS and DPP evolving theharmonized set of system level SGIS and DPPimpacting the evolution of the SGIS-SLs and SG-DPCs.

The ESOs need to provide a sustainable mechanism toupdate and synchronize the bonds of data models used byfunctions and use cases to the SG-DPCs and their SG-ISLrequirements. This is required to link and synchronizeuse case and data model repositories as well as derivedstandards for smart grid system components (products,

solutions, services) and organizational standards whichneed to be in sync with changing system requirementsfor the smart grid information security (SGIS) and dataprotection/privacy (DPP).

ISec-4 ESO to provide IT Tools to supportSGIS and DPP modelling and repositories forSG-ISL/SG-DPC

As mentioned above (ISec-3) there are two distinctevolutionary areas the smart grid operation model andthe SGIS model, with different innovation dynamics - bothareas need to be supported by tools that allow expertsin both areas to dene the content and models and thatinterlink, each with the capability to inherit changes fromthe other area. The set of tools and repositories are uniqueto the area. Therefore the tools for modeling SGIS aredifferent. The need for tools and repositories required inthe area of the smart grid operation model to capturefunctions, use case scenarios and use cases and all datamodels with their specic classications are described inanother section of this report.

The ESOs should also provide tools specically for thearea of SGIS, DPP and the repositories for SGIS-SLand SG-DPC to experts and communities in the area ofinformation security to assist them in modelling SGIS and

DPP and maintaining and upgrading repositories for the 5information security levels (SGIS-SL), and the repositoriesfor smart grid data protection classes (SG-DPC). Thetools provided to model SGIS, DPP system level and onthe actor level (products, solutions, services and people,roles or organizations) and the repositories for SGIS-SLand SG-DPC need to be interlinked.

As mentioned above (ISec-3) there is the need to keepthe two areas synchronized at all times. Therefore, thetools to be provided for both areas also need to permitsynchronizing and binding, i.e. the repositories containingall SG-DPCs and their specic required/linked SGIS-SLsto the repositories containing the functions/use cases and

their specic data models (to allow binding to the SG-DPCspecied for the single data model).

Dep-1 Check relevance of existingmethodologies to smart grids

Ask TCs (56 and 65A) whether their methodologies (withregard to Dependability and Functional safety) are well-suited/applicable to smart grids.

Standardization recommendations regardingEMC and power quality

EMC-1 Review existing standardsCENELEC TC 210 and Product Committees to reviewexisting standards concerning an appropriate modicationfor closing gaps in order to also ensure EMC in thefrequency ranges from 2 kHz to 150 kHz (in practice2-9 kHz and 9-150 kHz).

NOTE - Technical input in this domain can be foundin several reports/publications, such as the CENELECSC 205A Study report on electromagnetic interferencebetween electrical equipment/systems in the frequencyrange below 150 kHz, (SC205A/Sec0260/R, April 2010).Nevertheless, further studies are probably necessarybefore a complete set of standards can be available.

Furthermore, the following actions of the standardizationcommunities are suggested to support low frequencyEMC/power quality in the context of smart grids.

EMC-2 Review EMC and Power Quality levelsReview electromagnetic compatibility levels and/orcharacteristics of voltage at interfaces for all standardvoltage levels of public electrical power networks, anddene the associated operating conditions in the contextof the smart grids.

EMC-3 Consider distorting current emissions

from DER equipmentStandardize how to give a limitation to the distorting currentemission by DER equipment and to fairly allocate the abilityof networks to absorb distorting current emissions amongpresent and possibly forthcoming connected equipment,including Distributed Generation at sites in networks.Connected equipment may well be other networks. Thework is recommended to originate from documents IEC

TR 61000-3-6, IEC TR 61000-3-7, IEC TR 61000-3-13and future IEC TR 61000-3-14.

Gen-1 Harmonized glossary, semantic &modelling between back-ofce applications(CIM) and eld applications (IEC 61850)Provide experts to IEC/TC 57 body to boost CIM/IEC61850 harmonization planning, x this issue ASAP andestablish clear messages to the market. Support electronicform of IEC 61850 data model at IEC level based on UMLlanguage.

NOTE - IEC 61968 and IEC 61970 standards providemodels of transmission, distribution systems and energymarkets, as well as partial models of power generation,

models known as the CIM (Common Information Model),structure and semantics for integrating a variety of back-ofce applications.

IEC 61850 standard provides a model for substationautomation system and renewable energy resources(PV, hydro & wind and other), a basis for eld equipmentcommunications, including semantics, and encompassesreal-time operations as well as non-operational data, suchas condition monitoring.

Gen-2 Harmonization betweenIEC 62056-XX (DLMS/COSEM) data model

and IEC 61850/CIM Take the lead on this IEC 62056-XX (DLMS/COSEM) datamodel harmonization with CIM/IEC 61850, within the IECbody (through CENELEC/TC 57 and CENELEC/TC 13).

Gen-3 Extended eld data modellingstandard (part of IEC 61850) to supportdemandresponse, DER and VPP & ExtendedCIM to model more accurately GenerationFleet Management Applications in the caseof Bulk Generation, and to integrate DERand VPPsClearly express and formalize to CENELEC/TC 8X theselected use cases which the European smar t grids haveto support and ensure IEC TC 57/WG 17 body (throughCENELEC/TC 57) will provide expected answers in IEC

61850 data modelling regarding: Demand response forgenerators, for ancillary services, including VPPs andaggregators. Support TC 57/WG 13 initiatives to deneuse cases and modelling (such as AI715).

Gen-4 Standard for electrical connectionand installation rules to ensure energyavailability and security, in the presenceof a high ratio of DERHarmonize electrical connection and installation ruleswithin Europe, down to all levels of connection of DER.

Gen-5 Standard to allow all connectedgenerators associated in VPPs to participateto new ways of operating grid

Adapt installation rules of DER to allow new ways ofoperating grid such as microgrid (TC 64 and TC 8X).

More specically, TC 64 should develop new requirementsand adapt existing installation rules within the HD 60364to cover DER needs.

T1 HVDC grid architectureWith the development of off-shore grids, there is a need forcoordination, coherence and interoperability for equipment(converters, circuit-breakers, protection) as well as forgrid topology (grid design, voltage level, grid code,) in theHVDC domain. The ESO standardization should take intoaccount the work done in the German committee context.

T2 Smart assets The ongoing IEC 61850-90-3 work, devoted to conditionmonitoring in the power energy domain, should beencouraged. The present standard and protocol

for communication in substations should involvecommunication and relevant data models, whereasthe relevant products Technical Committees have tostandardize the methods and the devices needed foron-line monitoring.

Therefore, it is recommended that the ongoing IECstandard involves on the one hand the experts onequipment to monitor for the technical aspects and onthe other hand representatives of users in order to assessthe condition values.

T3 Offshore equipment A review of the existing standards for transmissionequipment is required in order to check that the specialrequirements for off-shore installations are properlycovered. Otherwise, standards should be adapted.

These tasks should be notably performed by TC 14(transformers), TC 17 (switchgear), TC 38 (instrumentmeasurement) and TC 20 (underground cable).

Dis-1: Feeder and Advanced Distribution AutomationDevelop a standard that supports feeder automation (atCEN/CENELEC), and Advanced Distribution Automation.

Dis-2: Use CIM (see also Gen-1)Give high priority to the works needed in the area ofharmonization of CIM /IEC 61850.

Dis-3: Seamless communication betweencontrol centre and substationSupport international work in order to provide seamlesscommunication between control centres and sub-stationsbased on 61850.

Dis-4: Develop cybersecurityaround IEC 62351Work on a standard for cybersecurity as long as intensivepublic communication services (from Telecom Operators)will be used in distribution, enhance IEC 62351 in this area.

Dis-5: Auxiliary power systemsstandardizationDevelop standardization for auxiliary power systems (lowvoltage DC networks): AC/DC converters, DC managementsystems, DC protection.

Dis-6: Integrate condition monitoringcapabilitiesCondition monitoring of components of substations or oflines provides technical information useful for optimizedloading and helps to increase the lifetime of the distributionassets. IEC 61850, the present standard and protocolfor communication in substations, should involvecommunication as far as the sensors needed for on-linemonitoring. Ongoing work in TC 57: IEC 61850-90-3 (TR).

Dis-7: Standards for Medium Voltage (MV)linesDevelop a set of standards covering V and I sensors,switching equipment (denition, and modelling) and faultdetectors (denition, and modelling) for Medium Voltagelines (overhead and underground).

SM 1:Currently various standards or extensions of existingstandards are being developed to cover the exchange ofmetering data. Examples are:

- EN 62056 Electricity metering Data exchange formeter reading, tariff and load control;

- EN 13757-1: 2002: Communication systems for metersand remote reading of meters;

- IEC 61968-9: System Interfaces for DistributionManagement Part 9: Interface Standard for MeterReading and Control.

While harmonization of EN 62056 and EN 13757 is alreadybeing undertaken, some standardization initiatives gobeyond the scope of M/441. A harmonization of standardsmore generally in this area is necessary to prevent furtherdevelopment of different (and competing) standards forthe same purpose.

SM 2:Smart metering, building/home automation and electricvehicles are envisaged as elements in smart electricitygrids. It is recommended that CEN/CENELEC/ETSIconsider the use cases involving these elements andtake care in their standardization work in these areasto ensure the needs and applications of smart grids areaddressed in a harmonized fashion.

SM 3:Specically to assist the development of proposals forpossible link technologies in relation to smart grids and

e-Mobility, it is recommended that CEN/CENELEC/ETSIshould jointly undertake an investigation of the interfacesrequired insofar as they are not currently being addressedwithin the M/441 mandate. The ESOs should proposewhere standardization in these areas is necessary, takingcare to ensure harmonization with existing meteringmodels and other relevant standardization initiatives.

Ind-1: Tariff informationOn-site energy management systems should be able tospread tariff information down to the load. We recommendextending the IEC 61850 model (the most commonbackbone system for EMS) to support tariff-relatedinformation.

Ind-2: DR information The demand response mechanism is not considered yetto support network ancillary services. We recommendextending the IEC 61850 model (DER) and other DRinformation channels to support ancillary servicesparticipation.

Ind-3: Smar t Meter and building systeminterfaceIn their work on data exchange between the smart meterand the building management system, the EuropeanStandards Organizations should ensure coordinationbetween CEN/ TC 247 and TC 13.

Ind-4: Harmonized data model for industryand power grid

Too many data models already exist without mappingbetween them. We recommend harmonizing the datamodel related to energy management between Industryand Electricity (EN 61158, EN 61850).This work shouldbe coordinated between CLC/TC 205, TC 65 and TC 57.

Ind-5: Electrical installation allowing for DERintegration

The usage of distributed energy resources as part ofelectrical installations and part of micro grids for industryraises new safety and protection issues. The multi-sourcesaspect is not covered by current installation rules. Werecommend TC 64 to work on new installation rules forsafety aspects and TC 8 or TC 99X to work on commonrules for grid protection. TC 64 should develop a dedicatedpart within the HD 60364 to cover this need, keepingin mind that all national wiring rules through Europeancountries are based on the HD 60364.

HB-1: Separate realization from standardsdescription

The use cases described above inter face with the eldof smart metering, but have to be logically separated. Instandardization, there are arguments for distinguishingmeter gateways from energy management gatewaysconsidering both applications as two logical blocks,since both elds are driven by different kinds of interestsand innovation speeds. Competition is likely to resultin different devices and technologies combining logicalapplications dened by standardization. In order to beopen for such market development and for innovation,

standardization should not dene the device but the logicalfunctions, data and interfaces in case these are needed forcommunication between different market roles or devices.

HB-2: Unied language for tariff information A unied language (a kind of common semantic layerabove the existing technologies) has to be dened tocommunicate demand response related elements (e.g.an incentive like a new price / tariff). A Europe-wide oreven worldwide unied data model for these aspectswould be favourable considering the global market forsmart appliances, devices and automation systems. Forthat purpose, data models/proles have to be developedfrom the use cases. A multi-stakeholder committeeconsidering the different domains and ESOs involvedshould be assigned this task of considering ongoing

initiatives (from research, industry and standardization).

This approach can succeed only by broad introductionincluding existing standard technologies. Therefore, theunied language must be mapped onto the communicationstandards lying below. These lower standards shouldsupport this mapping mechanism which is not thecase today.

DR-1 Create DR task force

Create a single DR task force at CEN/CENELEC/ETSI levelencompassing the adaptation of DR signals to manageDER and electric vehicle charging issues. Consider othercountries experiences and standards (OpenADR alliance,OASIS work in eMIX and Energy Interop committees,E-Energy).

Close coordination with the IEC/ISO and ETSI ITSstandardization bodies for communication exchangewith the EV.

DR-2 Avoid European mandates overlapping

Dene clear interface and responsibilities between thesmart grids mandate, the smart metering mandate andthe EV mandate and associated standardization bodies(part of smart grids mandate). Ensure interoperabilitybetween the different standards.

DR-3: Complement Data Model for DRsignals

Include pricing signals, DR signals and DR processinterfaces into CIM, COSEM and IEC 61850.

Mkt-1 Dened actors and roles as the basis ofsmart grid use casesStandardization should play a role also in other areas wheretechnical enforcement of market decisions by regulatorsor private sector actors is needed. Moreover, StandardsOrganizations have to provide the needed exibility toaccommodate the increasing variety of business models.

These needs must be based on an agreed set of use casesto be developed and maintained over time. All of those usecases should be based on the described actors and roles.

Mkt-2 Market communicationOne of the particularly important areas of ICT standardizationconcerns market communication standards like EDIFACT,etc. and their capability to provide the services andfunctionalities. Besides being of general interest tostandardization bodies and all other stakeholders, thisissue is of utmost interest to all market players (suppliers,generators, traders, etc.) and also network operators, asit ensures a uniform and efcient exchange of data andinformation in the market. It is the standardization bodiesfor electricity and the ICT sector together who will needto review and identify all the required improvements and

further developments in this area.

The European Committee for Standardization (CEN) isa business catalyst in Europe, removing trade barriersfor European stakeholders such as industry, publicadministration, service providers, consumers and otherstakeholders. Its mission is to foster the European economyin global trading, the welfare of European citizens, and theenvironment. Through its services CEN provides a platformfor the development of European Standards and otherspecications.

CENs 31 National Members work together to developvoluntary European Standards (ENs) in various sectors tobuild a European Internal Market for goods and servicesand to position Europe in the global economy. By supportingresearch, and helping disseminate innovation, standardsare a powerful tool for economic growth. More than 60.000technical experts as well as business federations, consumerand other societal interest organizations are involved in theCEN network that reaches over 480 million people.

For further information, please visit: www.cen.eu

The European Committee for Electrotechnical Standardizationis officially responsible for standardization in theelectrotechnical eld. In an ever more global economy,CENELEC fosters innovation and competitiveness, makingtechnology available not only to major businesses but alsoto SMEs through the production of voluntary standards.CENELEC creates market access at the European level butalso at the international level through its cooperation agreementwith the International Electrotechnical Commission (IEC).

Through the work of its 31 Members together with its experts,the industry federations and consumers, ElectrotechnicalEuropean Standards are created in order to help shapethe European Internal Market, to encourage technologicaldevelopment, to ensure interoperability and to guarantee thesafety and health of consumers and provide environmentalprotection.
