New Version of FLORIS Significantly Increases Computing Speeds | News

Major overhaul of open-source optimization tool could help boost productivity and profits of wind power installations


The National Renewable Energy Laboratory (NREL) Wind Energy Controls Research Team has announced the release of version 3.0 of the FLow Redirection and Induction in Steady State (FLORIS) wind farm control software. FLORIS optimizes flow control strategies so that existing wind installations can improve productivity and future projects can maximize profits.

“This release of the open source software represents a major overhaul, rewrite and improvement,” said Paul Fleming, NREL researcher and principal investigator. “It’s much faster — 100 times faster than 2.1 and 30 times faster than 2.4. It is also more accurate and supports more varied calculations.

Some of the most important enhancements that are now available for academics, makers, developers, and small businesses include:

  • Improved calculation speeds for calculating the annual energy production of the wind farm
  • Improved models of offshore wind farms
  • Mixed Turbine Model Capabilities
  • FLASC (Analysis for Supervisory Control) companion repository based on FLORIS.

The release of FLORIS version 3.0 comes after a six-week beta testing period, during which additional features were added and minor bugs were fixed, but there is more to come.

“Ongoing development of FLORIS continues,” said Fleming. “We are planning several new features, including even faster calculation speed, the ability to couple to hybrid power plant models, the continued improvement of wake models, and the modeling of axial induction-based wind farm controllers. .”

FLORIS was developed by NREL and Delft University of Technology with support from the US Department of Energy’s Office of Wind Energy Technologies. Funding was also provided by the National Offshore Wind Research and Development Consortium.
