Chapter 16: Wind Turbine Control Co-Design

Rotor, structure, platform, and controller as one system¶

Wind CCD coordinates aerodynamic capture, structural loads, platform motion, generator and pitch control, operating regions, reliability, and economics.

Learning objectives¶

After completing this chapter, you should be able to:

1. explain and apply rotor aerodynamics;

2. explain and apply structure and platform;

3. explain and apply torque and pitch control;

4. explain and apply load cases;

5. formulate and verify the chapter methods on fixed-bottom and floating turbines evaluated over design load cases.

Mathematical lens¶

The recurring quantities are blade, tower, platform, generator, controller, loads, AEP, and LCOE:

Running example¶

The recurring example is fixed-bottom and floating turbines evaluated over design load cases. Retaining one system prevents apparent improvements from being caused by changed physics, information, loads, or metrics.

Recommended workflow¶

1. parameterize turbine.

2. build coupled model.

3. evaluate load cases.

4. optimize plant and control.

5. validate multi fidelity.
