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.

In order to cope with the tasks of the “Energiewende“, Fraunhofer IWES has grown considerably in recent years. There were 200 staff members in 2009 compared with almost 500 in 2012.

Further expansion is essential and planned. The necessary structures for this expansion will be created in business year 2013. An example of this is the formation, in the north-west, of a wind energy research association by DLR, ForWind and Fraunhofer IWES. Together with the authorities in the State of Hesse and the city of Kassel, planning is on-going for a new, large institute building in Kassel.

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.
