Abstract: The Automatic Voltage Regulator (AVR) cannot respond generator output voltage quickly resulting in drop voltage and can be affected to the electrical system. AVR controller simulation model created in power system based on real data from National Electricity Company (PLN) ( Tello Power Plant Makassar case). AVR controller response time under normal conditions has the oscillation time of about 9 seconds and response time when loaded is about 15 seconds. Resulting unstable voltage in the system follows load changes. With the addition of Proportional Integral Derivative (PID) controllers acquired a controlling response time to changing loads faster and system voltage will change the voltage stability limit of ± 5% of nominal voltage. AVR controller with PID is very suitable for controlling the voltage of power generation system due to changes in load
