The impact of trailing edge flap on the aerodynamic performance of small-scale horizontal axis wind turbine

Aktham Mansi et al.

Summary: A new blade profile design with a fixed trailing-edge flap was investigated to improve the performance of small-scale HAWTs. The study used blade element momentum (BEM) and computational fluid dynamics (CFD) approaches to validate the design and determine the optimal blade profile based on the Weibull distribution. The results showed that the power coefficient of the new blade profile was higher than the reference design, although the CFD method over-predicted the power coefficient compared to the BEM method. According to the wind speed distribution in Turkey, the annual yield of the wind turbine with the new blade profile was higher than that of the reference blade profile.

Simulation of oscillating trailing edge flaps on wind turbine blades using ranging fidelity tools

John M. Prospathopoulos et al.

Summary: Recent research suggests that substantial reductions in fatigue and ultimate loads of wind turbines can be achieved by employing trailing edge flap control strategies. A comparison of various aeroelastic tools, including BEM-based models, higher fidelity lifting line, and CFD models, was conducted to evaluate the limitations of the tools. Results show that low-fidelity BEM tools consistently predict variations in rotor thrust due to flap motion, but struggle with reproducing detailed load distributions.

Active power control strategy of wind farm considering fatigue load of wind turbines

Jie Zhao et al.

Summary: An active power control strategy for wind farms considering the fatigue load intensity of wind turbines was proposed, utilizing turbulence intensity, average wind speed, and active power command for evaluation. An improved particle swarm optimization algorithm was used for optimizing active power distribution to maximize wind energy capture while keeping fatigue load intensity within an acceptable range. The strategy has been shown to reduce fatigue load intensity, lower operation and maintenance costs, and improve the economic efficiency of the power system.
