In a groundbreaking development for the wind energy sector, researchers have unveiled a new simulation environment that promises to enhance the efficiency of wind farm control strategies. This innovative coupling of a GPU-resident large-eddy simulation (LES) code named GRASP with the multiphysics wind turbine simulation tool OpenFAST could revolutionize how wind farms are analyzed and optimized.
Emanuel Taschner, the lead author of the study from the Delft Center for Systems and Control at the Delft University of Technology, emphasizes the significance of this research: “By integrating flow dynamics with turbine behavior in a single simulation environment, we can gain deeper insights into how to optimize wind farm performance under various weather conditions.” This integration is crucial as it allows for a more nuanced understanding of how individual turbines interact with the larger atmospheric conditions that affect their efficiency.
The research introduces an actuator line model (ALM) and a newly proposed filtered actuator line model (FALM), which aim to improve the accuracy of simulations. The FALM, in particular, has shown promise in reducing the overpredictions of lift and power that have plagued traditional ALM implementations, especially when working with coarse LES grids. “Our findings indicate that the FALM can provide more reliable predictions, which is essential for designing effective wind farm control strategies,” Taschner added.
The implications of this research extend beyond theoretical advancements; they hold real commercial potential for the energy sector. As wind energy continues to grow as a critical component of the global energy mix, optimizing the performance of wind farms becomes increasingly important. With the ability to simulate realistic weather conditions and turbine interactions, operators can make more informed decisions, potentially leading to increased energy output and reduced operational costs.
Moreover, the cross-verification of the new ALM with results from four other widely used LES codes enhances its credibility, ensuring that the findings can be trusted by researchers and industry professionals alike. The consistency in results for blade loads and near wake dynamics, coupled with the identification of deviations in the far wake, provides a comprehensive understanding that can inform future designs and operational strategies.
This research, published in the journal ‘Wind Energy’ (translated from German to English), sets the stage for a new era of wind farm simulations. As the industry increasingly relies on data-driven decision-making, tools like this simulation environment could become indispensable for engineers and operators looking to maximize the efficiency and output of wind farms.
