The paper present the dynamic oscillation of the electric power system. The concept of system resilience that functions for machines that move normally and can return to a stable state after a disturbance occurs. Oscillation of changes in speed and oscillation changes in the electric power system occur due to disturbances. Disturbance in electricity causes an electric current that works on the system beyond the nominal current. The effect of the current disturbance will have an impact on changes in the current torque parameters that cause prime-over instability when the generator is operating. This instability will affect the rotor speed and the voltage emitted by the generator. Dynamic oscillation repair testing by applying phase compensation control and PID-Controller on the excitation system is done to see the response of speed and voltage response when the system is experiencing interference. Observation of system oscillation response using matlab simulation to see system performance. The simulation results show that dynamic stability improvement with phase compensation method can reduce oscillation speed and voltage within 6 seconds and the use of PID-controller can reduce the speed and voltage in 3 seconds. The phase compensation method and PIDcontroller applied to the excitation system can reduce the electric power system oscillation.
