Testing wake control schemes using a fast time-domain wind farm simulator

Back
Abstract:
Turbine power and yaw set points can be adjusted across a wind farm to minimise power losses and additional fatigue loads caused by wake interaction. Detailed modelling is required to understand the complex flows in sufficient detail to allow a realistic practical control design. High-fidelity computational fluid dynamics requires enormous computational resources, so simpler engineering models are needed which capture the most important effects while running fast enough to allow sufficient testing. The presentation describes such a model, and to demonstrates its application for controller testing, an optimal sector management scheme designed using steady-state tools is tested in realistic time-varying dynamic conditions.

Biographical Sketch:
Ervin Bossanyi has a physics degree and a PhD in energy economics, and has been working on many aspects of wind energy and other renewables in the academic, industrial and consultancy sectors since 1978. Main contributions include development of detailed simulation models and advanced control concepts for commercial wind turbines. He is a co-author of the widely-used Wind Energy Handbook (Wiley, now in second edition), and was awarded the 2014 Scientific Award by the European Academy of Wind Energy. He is currently senior principal researcher in renewables at consultants DNV GL, and has an honorary visiting professorship at Bristol University.
