The Nordic Consortium, Optimization and Control of Wind Farms, was initialized by Professor Dan Henningson, Associate Professor Stefan Ivanell and Professor Jens Sörensen as a continuation of the PhD work performed by Stefan.  

The main aim is to continue the work on:

  1. basic reseach on wake stability, i.e. to quantify the mechanisms behind the breakdown of the wake structure and thereby to be able to estimate wake lengths etc.
  2. development of farm simulation tools to be able to optimize and control large wind farms.
  3. and to coordinate collaboration within wind energy projects in the field at Uppsala University, KTH and DTU in close collaboration with the industry.

with the following sub-goals:

  • Cost effective utilization of wind power parks
  • Increased understanding of wake interaction for improved modeling
  • Optimize power generation from each turbine to improve total power
  • Optimize lifespan of turbine by minimizing loads from wake interaction
  • Educate researchers that can work with wind power in industry and education institutes

The Swedish part of the project is financed by the Swedish Energy Agency and VindForsk.

The project group consists of:
