Numerical design optimization of wind turbines

• Formulate an optimal design problem, i.e., identify the design variables and corresponding parameterization technique, choose suitable constraints and objective functions
• Perform sensitivity analysis of the proposed problems
• Estimate the optimal configuration of a wind turbine rotor blade or support structure, using some simplifying assumptions and basic load cases
• Computing critical constraints for design problems
• Numerically solve aerodynamic/structural optimization problems and conduct sensitivity analysis using specific optimization algorithms and techniques
• Carry out relevant engineering design studies using numerically optimization
• Interpret and analyze the results from the optimization process
• Write technical reports describing the work carried out throughout the course

The course is focused on the practical application of numerical optimization to solve common wind turbine design problems. However, much of the content is still relevant for other fields. The course will feature lectures of the following topics:

– Components optimization with focus on relevant problem formulations.
– Optimization theory and algorithms for nonlinear optimization.
– A brief review of aerodynamic and structural analysis methods, using methods typically used in industrial design
– Overview of the iterative process underlying the design optimization of wind turbine components.
– Determination of the design driving constraints and its relation with the different phenomena observed in wind turbine components.

The course is structured around 3 projects, students will have the option to focus on 1 of 3 design problems:

1) Wind Turbine Rotor Composite Structural Design.
2) Wind Turbine Rotor Aerodynamic Design.
3) Wind turbine steel offshore support structure design.

Following approval from the course responsible students will have the option to tackle their own design optimization project for the final project.

Students are expected to take this course later in the program once they have gained some understanding with wind turbine technology. It is also recommended that students are comfortable with Matlab programming.

Lectures, exercises and individual project work.
