Avifaunal impact. This attribute considers four levels and is represented by the amount of birds killed per turbine (for each wind energy scenario) and per plant (for the status-quo). Costs. This attribute has four levels, each considered as proxy levels for plant operation and maintenance and...
Wind turbine wake flows are known to be strongly affected by atmospheric operating conditions [6]. This is why the physics of the atmospheric flow and its interaction with wind farms was highlighted as one of the three grand challenges facing the wind energy industry [7]. One of the major ...
Keywords: wind turbine aerodynamics; BEM; pitch imbalance 1. Introduction The analysis of the performance of modern wind turbines is one of the most important research fields in wind energy as the aerodynamics of wind rotors is affected by several factors. The variability of the external conditions...
This improvement will have an increase in the availability of the turbine, and therefore in energy production. Keywords: condition monitoring; fault detection; machine learning; wind farm Graphical Abstract1. Introduction As a consequence of increasing climate change awareness, research on topics such ...
wake model, as it is a single-hat Gaussian-shaped wake model and does not include the effect of the nacelle in the near wake, which leads to significant differences between the proposed model and the actual data, especially in the near wake regions (greater distances from the down turbine)...
For example, the coupled model improves the ME, RMSE, and CC of the WRF raw forecast for turbine No.9 by 59%, 43%, and 8%, respectively. From Figure 5, it also can be observed that RM method is able to improve the raw prediction of the WRF-alone model; particularly, the ...
wind turbine simulation; atmospheric flow variation; aeroelastic analysis; wind turbine vortex wake; wind turbine blade1. Introduction In recent trends, wind turbines have been growing in size, and to manufacture these large turbine blades at a lower cost, they often adopt a lightweight design ...
offshore wind turbine; wind turbine blade; impact; damage; composite1. Introduction 1.1. Background The recent trends in the offshore wind turbine industry include bigger turbines with large size rotor blades as they increase the rotor swept area and power production, and are thus profitable for...
In order to extract efficient power generation, a wind turbine (WT) system requires an accurate maximum power point tracking (MPPT) technique. Therefore, a novel robust variable-step perturb-and-observe (RVS-P&O) algorithm was developed for the machine-side converter (MSC). The control strategy...
