PID Controlled Frequency Regulation Of Wind Turbine

Akash Alex Paret

In this paper the output frequency of a wind turbine system supplying an isolated load is regulated by controlling the rotor speed of the turbine using a PID (Proportional Integral Derivative) controller. The block diagram of the linearized model of the wind turbine system is described and simulated using Matlab-Simulink software package. The performance of the controller and hence the system response is optimized using Simulink design optimization and manual tuning of the PID controller. The performance of PID controller is compared with the Linear Quadratic Regulator control scheme under nominal and extreme conditions of operation of the wind turbine.
