Researchers have developed a novel framework that combines the Analytical Hierarchy Process (AHP) and VIKOR multi-criteria decision-making techniques to select the best materials for wind turbines, with a focus on enhancing corrosion resistance and efficiency. By evaluating seven different materials against 16 critical factors, including corrosion resistance, mechanical properties, cost, and environmental impact, this integrated approach helps designers choose the optimal material to improve wind turbine performance and extend their lifespan. This innovative solution addresses a critical challenge in the wind energy sector, paving the way for more sustainable and reliable renewable power generation. Wind power and renewable energy play a crucial role in the global transition to a cleaner, more sustainable future.
Tackling Corrosion: A Critical Challenge in Wind Turbine Operations
The durability and lifetime of wind turbines are major concerns due to the detrimental effects of corrosion. Corrosion can significantly impact the performance and reliability of wind turbines, leading to reduced efficiency and increased maintenance costs. To address this challenge, researchers have developed a hybrid decision-making framework that combines the strengths of two powerful techniques: AHP and VIKOR.
Integrating AHP and VIKOR for Optimal Material Selection
The AHP method is used to determine the weights of 16 critical indicators, including corrosion resistance, mechanical properties, cost, and environmental impact. This ensures a structured and comprehensive evaluation of the materials. The VIKOR technique is then employed to rank the seven material alternatives and identify the optimal compromise solution that balances all the relevant factors.
Evaluating the Alternatives: Seven Materials under the Microscope
The researchers examined seven material options for wind turbine construction:
1. Nickel-Based Superalloys
2. Carbon Fiber Reinforced Polymers (CFRP)
3. Stainless Steel
4. Titanium Alloys
5. Inconel
6. Ceramic Matrix Composites (CMCs)
7. Single Crystal Alloys
The Winning Material: Carbon Fiber Reinforced Polymers (CFRP)
After a comprehensive evaluation using the AHP-VIKOR framework, the researchers found that Carbon Fiber Reinforced Polymers (CFRP) emerged as the best material for wind turbine construction. CFRP exhibited the highest similarity to the positive ideal solution and the closest relative closeness to the ideal solution, making it the optimal choice for enhancing wind turbine performance and durability.
Implications for Sustainable Wind Energy
The integration of AHP and VIKOR methods provides a robust and systematic approach to material selection for wind turbines. By considering a wide range of factors, including corrosion resistance, mechanical properties, cost, and environmental impact, this framework ensures that the chosen material not only improves the technical aspects of wind turbines but also aligns with the broader goals of sustainable energy development.
Advancing the Wind Energy Sector
This innovative research paves the way for more reliable and efficient wind turbines, addressing a critical industry challenge. By identifying the optimal material for wind turbine construction, the researchers have made a significant contribution to the sustainable growth of the wind energy sector, ultimately supporting the global transition to cleaner and more reliable sources of renewable power.
