Fast yaw optimization for wind plant wake steering using Boolean yaw angles

Abstract. In wind plants, turbines can be yawed into the to steer their wakes away from downstream and achieve an overall increase in plant power. Mathematical optimization is typically used determine best yaw angles at which operate a plant. this paper, we present new heuristic rapidly method, define turbine as Boolean – either predefined angle or nonyawed opposed typical methods of defining continuous with fine discretizations. We then optimize should algorithm that sweeps through most upstream downstream. demonstrate our method find perform well compared traditionally gradient-based optimizer for are defined continuous. There less than 0.6 % difference optimized power between two randomly placed layouts optimal annual energy production real farm. Additionally, show much more computationally efficient traditional method. For plants nonzero angles, generally able solve 50–150 times faster, some extreme cases up 500
