Special Issue Information

Dear Colleagues,

Wind energy plays a critical role in meeting the global energy demand while maintaining an eco-friendly and clean approach. To make wind energy more economically viable, modern wind turbines are becoming bigger and taller, thereby increasing their maximum power rating. Improving the cost-effectiveness of such large turbines (e.g., capacity factor and reliability) and reducing their environmental impact (e.g., noise) are the key goals of the ongoing research.

The challenges impeding the achievement of these goals are significant, requiring outstanding research and innovation in various areas, including aerodynamics, controls and structures, to name a few. This Special Issue will consider any papers on research topics relating to the "design and dynamic control of wind turbines". Topics of interest for publication include, but are not limited to:

  • Wind energy prediction for wind farms;
  • Wind turbine aerodynamics and aeroelasticity;
  • Aerodynamic efficiency and the upscaling of wind turbines;
  • Design of low-noise-emission airfoils;
  • Noise control and environmental impact;
  • Control and modeling of fixed and floating wind turbines;
  • Wind farm control;
  • Anomaly detection and compensation;
  • Design and analysis of foundations and support structures;
  • Loadings on fixed and floating wind turbine structures;
  • Wave–structure interaction/soil–structure interaction;
  • Innovative tower design concepts.

Direct-drive generators are recognised for their low maintenance compared with conventional drivetrains, largely due to their fewer working parts. However, consequent to low-speed operation, these machines necessitate large diameters and are subject to rigorous stiffness requirements. Significant internal and external forces influence structural integrity, so to design them efficiently, consideration of all operating parameters is imperative. Therefore, through Finite Element Analysis, this paper sets out to quantify the influence of each operating parameter on the integrity of a parametrically optimised rotor structure under established operating conditions and introduces operating temperature to the current models. An environmental impact analysis of the optimised rotor structure and cost analyses of both the optimised and unaltered structures are carried out simultaneous to the design process. We find the use of parameter optimisation alone to be insufficient for rotor structures of this scale due to high increased mass and costs of manufacture. A significant finding from this study is that the thermal effects on large-scale direct-drive generator structures may be vastly underestimated and have a much greater influence on structural integrity than first thought.
