3. Introduction • Working Group C6.11 • August 2006 – August 2010 • 27 members and experts representing 14 countries • Terms of Reference: • Global definition of Active Distribution Networks (ADNs) • Current status of deployment • Stakeholder recommendations Samuel Jupe – UK – Session 5: Planning and System Development – 0311

4. Shared global definition • Active distribution networks (ADNs) have systems in place to control a combination of distributed energy resources (DERs). • DERs are defined as generators, loads and storage. • Distribution system operators (DSOs) have the possibility of managing the electricity flows using a flexible network topology. • DERs take some degree of responsibility for system support, which will depend on a suitable regulatory environment and connection agreement. Samuel Jupe – UK – Session 5: Planning and System Development – 0311

5. Actual status of deployment • 24 flagship projects across the world • Analysed according to: • Integration level • Enabling technologies • Application • Benefits • Research and development needs Samuel Jupe – UK – Session 5: Planning and System Development – 0311
