Outline

• What is ENARD?• What are the different Annexes?

– Objective and scope– Deliverables, outcomes,…

• Role of ENARD in the future– Link with ISGAN

ENARD

• IEA Implementing agreement on – Electricity Networks Analysis, Research and Development (ENARD)

– Addressing a variety of electricity T&D network issues

– www.iea-enard.org

Structure of ENARD

• Executive Committee (ExCo)– Belgian delegate: Gabriel Michaux, FOD Economic Affairs

– Alternate: Johan Driesen, K.U.Leuven

• Annex I: Information Collation & Dissemination• Annex II: DG System Integration• Annex III: Infrastructure Asset Management• Annex IV: Transmission Systems• Annex V: International Knowledge Exchange of Smart Grids

Demonstration Projects (start-up)

• Belgium is active in Annex II and Annex IV through K.U.Leuven• Participation of 14 countries:

– Austria, Belgium, Denmark, Finland, France, Italy, Netherlands, Norway, South Africa, Spain, Sweden, Switzerland, UK, USA

Annex II: Objectives

• Objectives:– to build up and exchange knowledge on DER system

integration aspects and existing active network approaches– to develop guideline(s) for network operators and political

decision makers– to promote implementation possibilities for active distribution

networks

Annex II: DG System Integration

• Deliverables and Outputs:– Detailed in-country surveys of current state-of-the-art, lessons

learnt, limitations, future developments – Complementary foresighting activities and abstraction of

visions/goals for the future (e.g. growth of future fully integrated active networks)

– Compilation of an international overview report drawing out key messages

– Identification of requirements and needs for future work

– Report is recently finished and available on the ENARD website

Annex III: Infrastructure Asset Management

• Aim: To address the challenges associated with the management of increasingly ageing T&D asset bases within the participating countries and beyond

• Objectives:– development of a robust international information base– development of detailed understanding of risk based definitions and

methodologies– to source, collate and analyze relevant case study

– to compile a comprehensive information base

– and digest

• Report phase I finished and available

8

Annex IV : Transmission systems

• Objective and scope:– To establish a long term vision for developments in transmission

systems– Address the main barriers and identify the most important

challenges towards this vision – Two main activities to identify and describe the most promising

solutions related to operational and planning aspects (also taking into account technology developments):

• Task 1: Transmission Expansion Planning and Market analysis• Task 2: Transmission System Operation Management and Security

– Address the specific R&D activities needed as a result of the vision.

– Report is about to be finished in the next months

Annex IV: Vision• Paradigm shift:

– Variable generation will be a main part of the base power– Fossil fuel (previously “conventional”) generation becomes peaking units

• Increasing need for power transmission and energy storage – Generation further away from load centres and increasing variations in power flow

– Increased value of interconnections and energy storage due to• Periods of generation surplus and risk of negative prices• Longer periods of low wind and lack of production capacity

• Large capacity (multi-GW) connections will be more common– These will challenge present security standards (n-1 and similar)

• Flexibility becomes increasingly important– Creates possibilities for “smart solutions” in distribution and transmission

• Market evolution– Market design must reflect and support the changes in the system– Intra-day and real-time markets will become increasingly important

Annex IV: Key messages (1/2)

• Stimulate investment in transmission capacity!– Underinvestment may be more costly!

– Visionary thinking is needed (“a big leap”) to reach the political targets of a sustainable and climate friendly energy system

– Marginal grid expansions are not sufficient to make optimal use of the transformed generation system

– The economical tools to stimulate investments must be developed

– Grid development takes time: Stable economic environment is needed

– Commitment and understanding from society!

• Transmission expansion planning under greater uncertainty:– Coordinated planning processes most important!

– Development of new methods and tools for integrated transmission planning and market analysis, addressing also short-term power capacity problems

– Optimize the use of the assets (existing corridors, ..) New R&D can raise capacities in the existing grid.

10

Key messages (2/2):

• System operation management:– Better understand the challenges related to balancing the variability of the future

system– Development of new operational tools and methods for improved situational

awareness (manage all new measurements and information available and make best use of it!) Security of communication..

– Solutions for a “smarter transmission grid” (coordinated controls, demand side participation,..)

• Markets and regulatory challenges– Coordinated policy & market regimes to enable consistent grid and generation

planning

– Efficient and integrated market solutions and congestion management methods are key to optimize utilization of existing grids

11

Annex V : International Knowledge Exchange of Smart Grids Demonstration Projects

• Goal and Objective: Set up and promote the use of a common framework for the analysis and research of smart grid architectures

• Results:– Software: A web based inventory of worldwide smart grids– Document: A common agreement and procedure on data

gathering and information exchange– A basic inventory of smart grid

demonstration projects and preliminary findings

Link with ISGAN

• Joint Declaration between ISGAN and ENARD– Scheveningen, 19-21 October 2011– Transfer of the ENARD knowledge and experience base

Link with ISGAN

Role of ENARD/ISGAN?

• Smart Grids is touched on by many– DSM– Storage– Vehicles– Wind/Solar/Ocean,...

• Linked all by electricity networks � Coordinating role
