Special Issue Information

Dear Colleagues,

With the increasing demand for global clean and renewable energy, wind, wave, and tidal energy sources have become key in the transition towards a sustainable future. More specifically, wind energy is becoming increasingly prominent, both onshore and offshore, due to continuous technological advancements and supportive policies.

In recent years, the rapid evolution of operation and maintenance techniques for wind turbines, particularly driven by advancements in artificial intelligence, has further transformed the landscape of the wind energy sector. These technological innovations have not only improved efficiency but also introduced new challenges and opportunities to enhance safety. Thus, as wind turbine technology continues to advance, effective maintenance management becomes crucial for maximizing the lifespan of turbines while ensuring operator safety and minimizing environmental impact.

This Special Issue focuses on the latest changes in wind turbine maintenance operations and safety, exploring the innovations, best practices, and case studies that pertain to these critical topics. We aim to compile recent research that analyzes current trends, existing challenges, and innovations in the operational maintenance and safety of wind turbines.

Authors are invited to submit articles on various topics, including (but not limited to) the following:

  • Novel predictive maintenance strategies.
  • Innovations in condition monitoring technologies.
  • Novel health structural assessment.
  • Risk assessment in maintenance operations.
  • The impact of aging wind farms on operational safety.
  • The integration of artificial intelligence and machine learning in maintenance.
  • Studies on incidents and accidents: lessons learned.
  • International regulations and standards related to safety.
  • Comparisons between traditional and modern maintenance approaches.
  • Effects of extreme weather on maintenance operations.
  • Remote maintenance: emerging technologies and their applications.
  • Case studies on optimizing operational performance.
  • Strategies for managing the complete lifecycle of wind turbines.
  • Innovations in design to facilitate safe maintenance.
  • End-of-life issues of wind farms.
  • The influence of reliability and availability on operation and safety.
  • An analysis of the age of wind turbine fleets in different locations, regions, countries, and/or geographical areas.
  • Related review papers.

To enhance the aerodynamic performance of vertical axis wind turbines (VAWTs) under complex gust conditions, the design parameters of the flap were optimized using the computational fluid dynamics (CFD) method combined with orthogonal experimental design and the SHERPA algorithm, and two gust models with mainly high and low wind speeds were generated by a self-compiling program to investigate the effects of three combinations of the chordwise mounting position of the flap, the moment of inertia, and the maximum deflection angle on the aerodynamic performance of the vertical axis wind turbine. The results demonstrated that adaptive flaps reduced the flow separation region and suppressed the formation and development of separation vortices, thereby enhancing aerodynamic performance. The adaptive flap was found to be more effective in high-speed gust environments than in low-speed ones. The optimal configuration—chordwise position at 0.4C, moment of inertia at 6.12 × 10−5 kg·m2, and a maximum deflection angle of 40°—led to a 57.24% improvement relative to the original airfoil.
