2. Outline
• What is ENARD?
• What are the different Annexes?
– Objective and scope
– Deliverables, outcomes,…
• Role of ENARD in the future
– Link with ISGAN
3. 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
4. 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
5. 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
6. 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
7. 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

9. 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

10. 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
11. 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
12. 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
13. Link with ISGAN
• Joint Declaration between ISGAN and ENARD
– Scheveningen, 19-21 October 2011
– Transfer of the ENARD knowledge and experience base
15. Role of ENARD/ISGAN?
• Smart Grids is touched on by many
– DSM
– Storage
– Vehicles
– Wind/Solar/Ocean,...
• Linked all by electricity networks Coordinating role
