The state-space model of single cage induction generator with the variable-speed fixed-pitch-angle wind turbine is connected to an infinite bus bar to study the power systems transients. The widely used current-mode proportional-integral control technique is taken as a reference. In comparison, the linear quadratic regulator (LQR) optimal control improves the dynamic stability of the system under a variety of disturbance scenarios. These include decreased mechanical torque due to falling wind speed, increased electrical torque demand, and a 3-phase fault simulated on the high-voltage transmission line. The results show that the linear quadratic regulator optimal control outperforms the current-mode control in all 3 scenarios. Citing Literature Volume27, Issue11November 2017e2412 RelatedInformation
