  1. Introduction Session II Dr. Bernd Buchholz, Siemens AG EU AC Smart Grids CIGRE SC C6 VDE

  2. Smart Grids - challenges and mission Smart grids‘ mission is to create a shared vision which enables Europe’s electricity grids to meet the challenges and opportunities of the 21st century, fulfils the expectations of the society and strengthens the European business context for the electricity sector and its international opportunities Environmental protection Liberalised Market Interconnections and gross border trade Sustainability through renewable generation – 22% in 2010 Customer market participation Energy efficiency – 18 % CHP in 2010

  3. Technology Platform SmartGrids: www.smartgrids.eu Germany Bernd Buchholz, Siemens Edmund Handschin, Uni Dortmund Urban Keussen, E.ON Italy Livio Gallo, Enel Carlo Sabelli, Terna

  4. Results so far: Vision –Strategic research agenda– Strategic deployment document RA1: Smart Distribution Infrastructure Transmission networks of the future New architectures and tools Long distance energy supply RA2: Smart Operations RA3: SmartGrid Assets and Asset Management RA4: European Interoperability of SmartGrids RA5: Cross Cutting Issues and Catalysts www.smartgrids.eu

  5. The key element of the vision Create a Toolbox of proven technical solutionsenabling existing grids to accept power injectionsfrom all kinds of generation plants How much energy will be transmitted from North Africa?

  6. Grid enhancement to transmit offshore wind power through Germany Vattenfall Europe Transmission Offshore wind power 2015 – 10 GW 2020 - 20 GW Strong resistance of the public against the erection of new overhead lines 850 km 400 kV AC until 2015 versus HVDC long distance? • Transfer of 4000 MW per link • Homogeneous balance of load flow in the AC grid • Improvement of stability

  7. Supergrid to transmit renewable energy from North Africa to Europe ?

  8. Current transmission system structure in Europe NORDEL IPS/UPS UCTE - 1 UK Nordel UCTE - 2 Turkey MA-GHREB DC AC SOON UCTE 1 2100 TWh/a 530 GW ? UPS/IPS Studies Centrel 10th. October 2004 1400 MW 1200 MW UCTE 2 TRK MAG NA 450 MW 600 MW

  9. Limits of transmission technologies Cable GIL Overhead Underground/ submarine GW GW 4 8 GIL 300 kV DC 1000 kV 6 3 800 kV DC GIL 500 kV 4 2 750 kV 550 kV DC 1 2 Cable 380 kV 380 kV km km 1000 2000 100 200 500 1000

  10. Questions • Which amount of power transfer from North Africa to Europe is realistic • Which technologies shall be applied • How acceptance can be reached for new overhead lines in the urban landscape of Europe
