In this paper, an approach for active power control of individual windturbines is presented. State-of-the-art controllers typically employ separatecontrol loops for torque and pitch control. In contrast, we use a multivariablecontrol approach. In detail, active power control is achieved by usingreference trajectories for generator speed, generator torque, and pitch anglesuch that a desired power demand is met if weather conditions allow. Then, alinear quadratic (LQ) optimal controller is used for reference tracking. In anOpenFAST simulation environment, the controller is compared to astate-of-the-art approach. The simulations show a similar active power trackingperformance, while the LQ optimal controller results in lower mechanical wear.Moreover, the presented approach exhibits good reference tracking and byimproving the reference trajectory generation further performance increases canbe expected.
