The change in voltage at the generator terminal is highly correlated with the change in reactive power at the center load. There are several reactive power sources in the power system including those from field amplifiers that are controlled by equipment called Automatic Voltage Regulators ( AVR ). Changes in reactive power in the system will change the voltage profile including the voltage at the generator terminal. To maintain the voltage level on the generator terminal, the  AVR  must be adjusted properly. Determination of the value of the amplifier gain on the  AVR  largely determines the performance of the  AVR  in stabilizing the voltage. Wind Turbine penetration greatly affects the system voltage. This research is to see the impact of voltage changes due to wind turbine penetration in sulseltrabar interconnection systems. Determination of  AVR  gain is generated from the Routh-Hurwitz equation. Furthermore, in this study PID control will be applied to increase the  AVR  output response. Determination of the correct  Kp ,  Ki  and  Kd  constants is obtained with the help of a MATLAB simulation model. The simulation shows that using a  PID  controller, the overshoot and settling times obtained are better. The maximum exceeded voltage is 1 per unit and the settling time is 10.15 seconds.
