ENTSO-E is THE European TSO platform

• Founded 19 December 2008 and

fully operational since 1 July 2009

• Represents 41 TSOs from 34

countries

• 532 million citizens served

• 880 GW net generation

• 305,000 Km of transmission lines managed by the TSOs

• 3,200 TWh/year demand

• 380 TWh/year exchanges

• Replaces former TSO organisations:

ATSOI, BALTSO, ETSO, NORDEL,

UCTE, UKTSOA


Key activities set out in Regulation 714/2009 (on cross-border electricity

trade, part of the 3rd Internal Energy Market Package)

• Deliver network codes

• Deliver network plans European / regional view of system needs (Ten-Year

Network Development Plan “TYNDP”)

• Deliver crucial aspects of market integration (“market coupling”)

• R&D Plan (fully included in EEGI – European Electricity

Grid Initiative, part of the SET Plan)

Through its members deliver the infrastructure to:

• enable markets to function,

• secure energy supply,

• meet climate change objectives through connecting RES

ENTSO-E has significant role in delivering

European energy and climate change objectives


ENTSO-E: Organised to deliver a range of services

1- Research & Development Plan

2- Monitoring and Knowledge Sharing


Guidelines on Dynamics Modelling

The work triggered by ENTSO-E System Development

Committee

An internal ENTSO-E document still under development

Part of the document has informational character on stability

phenomena

The document points out the main challenges on dynamics

modelling and studies

The document suggests CIM extensions related to dynamics


Guidelines on Dynamics Modelling – main challenges

TSOs need to deal with dynamics problems not only to

ensure feasibility of future investments but also to cope with

requests for extensions of existing synchronous areas

Utilization of a harmonized approach to optimize the

execution of different studies is required

Data exchange format, data exchange platform,

confidentiality


From a circular to a linear process: Are we still far from

this change?

Guidelines towards better studies

Clarity on needs; harmonization when possible

Information Model (CIM) Profile

IEC, IEEE Standards

Tools ready to fully support standards

Equipment vendors fully open to provide models for system

studies


ENTSO-E and CIM

• ENTSO-E needs and wants to have only one data exchange format

• ENTSO-E decisions towards CIM data exchange

• ENTSO-E organizes yearly Interoperability tests to ensure right and stable development

• The Roadmap for the implementation of next updates of the ENTSO-E CIM Profile avoids frequent changes in the ENTSO-E CIM Profile


ENTSO-E CIM/XML Profiles

Current ENTSO-E Profile is the profile tested in UCTE IOP in March 2009 in Paris.

THIS IS THE PROFILE THAT MUST BE IMPLEMENTED BY ENTSO-E MEMBERS.

It is named 1st edition of ENTSO-E CIM Profile

The draft version of the 2nd edition on the ENTSO-E CIM Profile will be tested in July 2011 – under development

Updates of this profile should follow the approved Roadmap

Proposals for changes are welcome and will be discussed within ENTSO-E, IEC and will be tested in the ENTSO-E IOP once agreed among IOP participants.

ENTSO-E CIM/XML Profiles

1st edition of ENTSO-E CIM Profile is published on ENTSO-E web site (CIM part: http://www.entsoe.eu/index.php?id=237)

ENTSO-E Boundary Set is available here: https://www.entsoe.eu/resources/cim/profiles/

A draft version of the 2nd edition of the ENTSO-E CIM/XML profile was developed for the ENTSO-E interoperability test in July 2010. It is also available on the ENTSO-E web site (https://www.entsoe.eu/fileadmin/user_upload/_library/resources/CIM/Interoperability_Tests/ENTSO-E_CIM_Model_Exchange_Profile_v2_draft_7_IOPversion_12July2010.zip)

The profile files for IOP 2011 – new draft of the 2nd edition of the ENTSO-E CIM Profile are available in CIM user group site.


IOPs and ENTSO-E CIM/XML Profiles

IOP July 2011, Draft version of the 2nd edition on the ENTSO-E CIM Profile - IEC CIM 15v25 (current version)

IOP July 2010, Draft version of the 2nd edition of the ENTSO-E CIM Profile - IEC CIM 14v15

IOP Dynamic, Nov 2009 – 1st edition on ENTSO-E CIM Profile + dynamics

IEC CIM 14v02

IOP March 2009 - 1st edition of ENTSO-E CIM Profile

IEC CIM 14v02 Migration

Not to be

implemented

Not to be

implemented

Decision expected

in Oct-Nov 2011


ENTSO-E exchanges in CIM – migration process to CIM

Two main ENTSO-E processes are subject to CIM migration

System development • Still in migration period.

• First data exchanges in CIM

started in February 2010.

DACF process• The goal is to complete migration stage

by the end of 2011

• First test exchanges started on 8 June

2010 and finished in the end of August

2010

• Now the second stage of tests for DACF

is running. TSOs are exchanging 6 files

per day in CIM (one day in a week) . The

goal is to verify the procedures and test

Communication channels.

• TSOs are building their converters to CIM

(operational systems to CIM)

“Planning exchanges” –

required for TYNDP,

regional initiatives, i.e. EU

3rd Energy Package

Day-Ahead Congestion

Forecast process – stable

exchange needed to

support system operation


Roadmap for future implementation of CIM

The aim: to structure the implementation effort. No yearly implementation. An exception could be only if a change is introduced which is critical for ENTSO-E processes

The implementation process is foreseen to last one year.

On regular basis the implementation effort is foreseen every three years, if necessary.

Next versions of the ENTSO-E Profile have to be approved by System Development Committee (SDC). In case of changes that affect operational data, System Operations Committee (SOC) decision is also required.

SDC or SDC&SOC decision ensures one year implementation period. Coming into force date is fixed and mandatory for TSOs


Roadmap for future implementation of CIM – example

of implementation

If the updated version of the 2nd ENTSO-E Profile for IOP 2011 is OK:

Approval by SDC and SOC in Oct-Nov 2011

2012 implementation year

Jan 2013 ENTSO-E switches mandatory to 2nd edition of the profile for all exchanges.


ENTSO-E IOP Report 2010

Finalized and published in mid August 2010

Available on the ENTSO-E web site:

https://www.entsoe.eu/index.php?id=240

Identified CIM issues were listed in the final report and submitted to

IEC WG13 for further discussion. CIM15 resolves most of the issues

CIM exchange and Dynamics

2nd edition of the ENTSO-E CIM Profile – draft version

IEC Standards: 61970-552, 452, 301, 456, (part 457 -

dynamics – under development)


CIM for Dynamics – Simple connection; Cross compound

connection possible as well


CIM for Dynamics – Example PSS2B model


CIM for Dynamics – CIM UML model


CIM for Dynamics – Next steps

• Include additional standard models in the CIM. No complete data exchange is possible without this.

• Update the Standard models reference manual and prepare user-defined models and proprietary models manual. It is needed for proper documentation and IEC standards.

• Include all manuals in IEC standards

• Create a process to update the standards and UML; model repository; gather models from TSOs, manufacturers and harmonise between IEC and IEEE


Conclusion remarks

Challenges in dynamics modelling are obvious; complexity increases

with the scale

IEC CIM Standards (and derived CIM Profiles such as ENTSO-E one)

are important for the interoperability and ensure smooth data exchange

Vendors and manufactures involvement as well as utility involvement is

very important to keep models up to date covering various needs

Standard models/user-defined models/proprietary model exchange

allows flexible exchange between parties keeping confidentiality as

agreed

Vendors’ commitment is very important to have IEC CIM standards

implemented as soon as possible.
