1. GREDOR - GREDOR - Gestion des Réseaux Electriques de Distribution Ouverts aux Renouvelables Project scope - Présentation du projet Moulin de Beez, 29/04/2015 Raoul Nihart, EDF-Luminus

2. Why a project? GREDOR - Gestion des Réseaux Electriques de Distribution Ouverts aux Renouvelables 2 Introduction of Renewable Energy Sources (RES) in electric distribution grid induces a change of paradigm ”Going from centralized energy production to decentralized production” “Going from unidirectional power flows to bidirectional power flows” BUT this change has not been followed by the distribution grid design! Distribution Grid was originally designed to bring electricity to the final consumers. It is now also used as an entry point for renewable energy thus increasing the risk of congestion! Today’s situation

3. Why a project? GREDOR - Gestion des Réseaux Electriques de Distribution Ouverts aux Renouvelables 3 This change of paradigm is associated with  Growing electrification (Electric Vehicles, Heat Pumps,… )  Challenges induced by the intermittent production of RES (solar, wind,…) leading to a need for huge changes in the design and operation of distribution grids If nothing changes  Evolution of RES integration will slow down  Quality of power supply may decrease  Distribution costs may increase GREDOR is a research project funded by the Walloon Region with two main objectives 1.Define and Analyze market models including e.g. integration of flexibility services, renewable energy sources… 2.Implement decision making support tools for distribution grid operators in order to help them evolve in this new landscape by taking optimal decisions for the social welfare GREDOR is a research project funded by the Walloon Region with two main objectives 1.Define and Analyze market models including e.g. integration of flexibility services, renewable energy sources… 2.Implement decision making support tools for distribution grid operators in order to help them evolve in this new landscape by taking optimal decisions for the social welfare

5. Total Budget: 4,3 M€ Five main tasks shared between the Partners 1.Design and recommendation for a new market model 2.Design and development of a decision making support tool for grid investments 3.Design and development of a decision making support tool for short term congestion management 4.Design and development of a decision making support tool for real time congestion management 5.Customization of production and consumption data to create use cases for testing the different decision making systems Project leader: University of Liège (ULg) Supervised by the CWaPE (Commission Wallonne Pour l’Energie) Website: https://gredor.be/https://gredor.be/ GREDOR - Gestion des Réseaux Electriques de Distribution Ouverts aux Renouvelables 5 Project organization

6. Objectives of the project GREDOR - Gestion des Réseaux Electriques de Distribution Ouverts aux Renouvelables 6 Long Term Grid Investments Short Term Congestion Management Real-Time Congestion Management How to define the path towards smart grids Which type of investments should be made? How to take into account RES and flexibility services in investment decisions? How to define action plan (network reconfiguration, flex services,…) in order to manage short term congestion? Which actions may affect other stakeholders ? How to deal with this? Which data should be exchanged? How to solve in real-time a congestion Which action should be taken? Which data should be exchanged? WP 2 WP 3 WP 4 Market Models + Scenarios How to deal with actual and new stakeholders in order to optimize RES integration, achieve active network management, avoid/prevent congestion and call for flexibility services in such a way that social welfare is optimized and system balance is ensured WP 1

7. Timing: 48 months  Started: February 2013 & Deadline: January 2017  The five tasks are running in parallel  Task 1 and task 5 are feeding Tasks 2, 3 and 4 with  Scenarios and local instantiations  Use cases  Load and flexibility profiles  Current status: mid project, different market models under discussion, decision making systems under development Main deliverables  Scientific reports: detailed description of the solutions /results  Decision making support tool for grid investments, short term and real time congestion management GREDOR - Gestion des Réseaux Electriques de Distribution Ouverts aux Renouvelables 7 Timeline and main deliverables
