11:00 - 12:30 : OFFSHORE GRID CONNECTION

Room K11

Chair:
Frans van Hulle, European Wind Energy Association (EWEA)
Bo Normark, Power Circle / Royal Swedish Academy of Engineering Sciences (IVA)

Session description

The session will seek to answer the issue of how to optimally connect wind farms and the electrical network from a technical and economic point of view with due regard to reliability. A design concept of offshore HV AC platforms for connecting large wind farms will be outlined. An integrated design approach will be presented, which reduces the risk by providing an optimised solution for the complete electrical system from single turbine to the fixed grid. The session will also present a methodology for increasing the reliability of offshore wind farms by providing redundancy in the offshore transmission assets in an economically optimised way. Finally, the session will highlight methods of meeting stability requirements and grid compliance by the use of STATCOMS.

14:00 - 15:30 : FORECASTING

Room K11

Chairs:
Hannele Holtinnen, VTT Technical Research Centre, Finland
Colin Morgan, Garrad Hassan, United Kingdom

Session description

Energy and power management of large offshore wind power plants will be a challenge for the companies and system operators involved. An accurate wind production forecast, together with uncertainty measures, will be needed. Offshore wind resources differ from those onshore. Issues such as the lack of knowledge regarding meteorological phenomena at sea and the weakness of the existing meteorological network are significant problems. This session will present forecasting techniques and models required to address the challenges of offshore wind power production. How much does the task of forecasting differ offshore from onshore, and how far can we rely on the existing techniques?

16:00 - 17:30 : COMBINING OFFSHORE INTERCONNECTORS AND WIND FARMS: OPPORTUNITIES AND CHALLENGES

Room K11

Chairs:
Justin Wilkes, European Wind Energy Association (EWEA)

Session description

Integrated solutions for grid development and wind farm development in the Baltic and North Seas are increasingly being considered. What opportunities exist to combine offshore wind power production and the trade of electricity between European electricity markets? What are the main challenges in combining grid development and wind farm development and what needs to happen to overcome these challenges?
