  1. 1. IEA implementing agreement ENARD david.bekaert@esat.kuleuven.be johan.driesen@esat.kuleuven.beOutline• What is ENARD?• What are the different Annexes? – Objective and scope – Deliverables, outcomes,…• Role of ENARD in the future – Link with ISGAN
  2. 2. ENARD• IEA Implementing agreement on – Electricity Networks Analysis, Research and Development (ENARD) – Addressing a variety of electricity T&D network issues – www.iea-enard.orgStructure 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
  3. 3. 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 networksAnnex 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
  4. 4. 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 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 8
  5. 5. 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 9Annex 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
  6. 6. 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
  7. 7. Link with ISGAN• Joint Declaration between ISGAN and ENARD – Scheveningen, 19-21 October 2011 – Transfer of the ENARD knowledge and experience baseLink with ISGAN
  8. 8. Role of ENARD/ISGAN?• Smart Grids is touched on by many – DSM – Storage – Vehicles – Wind/Solar/Ocean,...• Linked all by electricity networks Coordinating role
