1. RT1b – EDF R&D Frankfurt (Germany), 6-9 June 2011  Smart Grids require a system approach and modularity  Smart Components will rely on nodes of integration in the information system  Solutions for e-mobility should be simple, economical and centered on customers Olivier Huet – France – RT1b Components for smart grids and e-mobility

2. RT1b – EDF R&D Frankfurt (Germany), 6-9 June 2011 A system approach that require components Smart Grids need a system approach based on interoperability, common requirements and standards The need is not « equipment » but components that are standardized, modular in their design and could be integrated as nodes in the information architecture Example of this approach in the Synerdis Project :  Harmonization of requirements between utilities (France, Hungaria, Slovakia, Germany and UK)  Definition of « smart grids » Functional Units that can embed communication, metering, fault detection, sensors, ….

3. RT1b – EDF R&D Frankfurt (Germany), 6-9 June 2011 Smart components will rely on nodes  The main difficulty is to specify separately electric equipment and information system : design of the smart grids should rely on an integrated approach  The EU FP7 project addresses 3 key R&D objectives : 1. Secondary susbstation nodes (SSN) : gathering information and making the appropriate control for the futur of distribution network 2. A software layer to couple operation of SSN into the Information System of utilities (supervision, management, DMS…), 3. A modular communication architecture based on protocols from standards that would bring sufficient flexibility to address future needs

4. RT1b – EDF R&D Frankfurt (Germany), 6-9 June 2011 Example of functionalities covered by e-nodes  Core functionalities : Monitoring and data management Basic automation Metering infrastructure Remote action  Advanced functionalities State estimation Volt and Var control Load management Decentralized intelligence Connection of EV

5. RT1b – EDF R&D Frankfurt (Germany), 6-9 June 2011 Solutions of E-mobility should be simple, economical and centered on customers The main stake of e-mobility is management of peak power !  Smart charging should be enabled and signals managed by network operator to prevent overload  Metering and billing should include very simple and economical solution such as tariff signal sent by PLC Users should be at the center of this integration Projet CRAFF Impact of standard EV charge on a distribution feeder if not managed Geo location tool of EV
