Fraunhofer Institute for Wind Energy and Energy System Technology

Schwerpunkte Buehne

Objectives and Main Areas of Work

The research activities of the Fraunhofer Institute for Wind Energy and Energy System Technology IWES cover all aspects of wind energy and the integration of renewable energies into energy supply structures. The main areas of research are:

  • Technology and operational management of wind turbines and wind farms
  • Dynamics of wind turbines and components
  • Component development for rotors, drive trains, and foundations
  • Test and evaluation methods for wind turbines and components
  • Environmental analysis of wind, sea, and seabed for utilization of wind energy and marine energy
  • Control and system integration of decentralized energy converters and storage systems
  •  Energy management and grid operation
  • Energy supply structures and system analysis

Development of Fraunhofer IWES

Fraunhofer IWES was founded at the start of 2009 through the merger of the former Fraunhofer Center for Wind Energy and Maritime Engineering CWMT in Bremerhaven and the Institut für Solare Energieversorgungstechnik ISET e.V. in Kassel. By agreement with the Fraunhofer-Gesellschaft, the institute directors are linked to professorships at the universities in Hanover and Kassel. Fraunhofer IWES in Bremerhaven has been headed by Prof. Dr. Andreas Reuter since 1 October 2010. At that time he was also appointed Professor of Wind Energy Technology at the University of Hanover. He succeeded the acting director, Dr. habil. Hans-Gerd Busmann, who since 2006 had headed the CWMT. The Kassel site is led by Prof. Dr. Jürgen Schmid, who has been chairman of the ISET Executive Board since 1998.

The institute continued to grow in 2010 and revenues were increased to approx. € 22 million euros in total. The above average increase in industrial funding by about one third to a level of € 3.7 million euros is a most gratifying development. To meet its new challenges, IWES started 2011 with over 230 employees as opposed to 200 in 2010. Besides the continuing growth in Bremerhaven and Kassel, two new project groups were formed in 2010 covering the research areas of support structures (University of Hanover) and aerodynamics (University of Oldenburg). These groups will further enhance the national and international reputation of Fraunhofer IWES.

Key Area of the Future: Wind Energy

Targeted collaboration instead of individual actions. The highly networked research alliance between Fraunhofer IWES and ForWind is able to carry out long-term, strategically important projects in the area of wind energy research. April will mark the first anniversary of the operation of the alpha ventus offshore test wind farm. Fraunhofer IWES is coordinating the rave initiative which is carrying out research activities at the test wind farm. The findings will benefit the whole sector. These developments are being supported by cross-system research at Fraunhofer IWES.

Key Area of the Future: Energy System Technology

The further expansion of regenerative energies and consequent replacement of conventional generating capacity requires sustainable reorganization of the energy supply structures by using modern power electronics and the networking and coordination of genera­tors, grids, storage systems, and consumers. The objective of future R&D work must be to design supply structures such that grid stability and reliability of supply remain guaranteed for the situation with a growing number of fluctuating energy generators, and even without large capacity reserves.
