# Dynamic performance analysis for wind turbine in complex conditions. This article presents a method to get dynamic responses of a wind turbine under different conditions. The time-varying load acting on the blade is calculated by using the blade element momentum theory, and the dynamic performance of the wind turbine are calculated by applying the modal superposition method with blade loads as excitations. The dynamic response process is adopted to carry out a dynamic analysis, and theoretical results are compared with experimental results, indicated that the analysis presented in this paper is correct. The results indicate that the wind turbine experiences a huge transverse vibration under turbulent wind, the hub vibration is intensified up to 179.52 %, and the vibration of the blade tip intensifies up to 190.41 % under the action of gusts in extreme conditions relative to the steady state, which shall be considered during design. * This article presents a computing method to get dynamic responses of a wind turbine under different conditions.

# A comprehensive review of numerical simulation techniques for wind turbines: from computational fluid dynamics and finite element analysis to advanced turbulence modeling. This review critically examines state-of-the-art numerical methodologies for the simulation of wind turbines, offering a rigorous exploration of their theoretical foundations, practical implementations, and comparative performance. The core of the study delves into advanced computational techniques encompassing computational fluid dynamics (CFD), finite element analysis (FEA), and fully coupled CFD-FEA frameworks used to resolve aerodynamic, structural, and fluid–structure interaction phenomena with high fidelity. The paper systematically analyzes turbulence modeling strategies, from industry-standard Reynolds-averaged Navier–Stokes (RANS) models to high-resolution large eddy simulation (LES) and hybrid detached eddy simulation (DES) approaches, evaluating their capabilities in capturing unsteady flow structures, vortex dynamics, and wake interactions. Through a comparative synthesis of these methods, the paper provides deep insights into their trade-offs in terms of computational cost, physical realism, and practical applicability, ultimately guiding the selection and optimization of simulation strategies for advanced wind energy system design and performance evaluation. ### A comparative study of RANS-based turbulence models for an upscale wind turbine blade.

UNM Digital Repository University of New Mexico UNM Digital Repository. # WIND FARM OPTIMIZATION AND ANALYSIS OF COMPLEX WAKE STRUCTURES. ## Author. A high-fidelity computational solver was developed with direct numerical simulation (DNS), large eddy simulation (LES), and Concurrent Precursor Method (CPM) capabilities. Extensive validation ensured the solver's accuracy in modeling fluid dynamics, including the wake characteristics of both utility and miniature-scale wind turbines. The study examined the influence of ground clearance on turbine performance, comparing two scenarios with different hub heights. Finally, the study uses a nine-turbine array model to explore wind farm behavior under varying wind conditions and yaw angles. This analysis highlighted that wind speed variations and yaw adjustments impact wake characteristics and power output, with implications for optimizing wind farm efficiency.

The SUMR-D BL control has two main operating regions, as shown in Figure 1: Region 2 (R2) operation is active in below-rated conditions, where generator torque is actuated to maximize power output at a given wind speed, and Region 3 (R3) operation is active in above-rated condi-tions, where the turbine blades are collectively pitch-actuated to manipulate the aerodynamic torque on the rotor to regulate the power output to the rated capacity of the turbine. See the Terms and Conditions (https://onlinelibrary.wiley.com/terms-and-conditions) on Wiley Online Library for rules of use; OA articles are governed by the applicable Creative Commons License 6 | CONCLUSIONS AND RECOMMENDATIONS This study presents the development of gust-measure-based advanced control techniques to improve generator speed regulation and mitigate overspeed events in high turbulence, gusty wind conditions. To mitigate the occurrence of such peaks, the BL controller from the field test is improved using gust estimation techniques to predict the likelihood of an incoming wind gust and to de-rate the turbine as needed to better regulate the generator speed in near- and above-rated wind conditions.
