Operation of an electric power system through a transmission network that has limited capacity can cause system instability when the system is disturbance. This study aims to investigate the influence of dynamic loads on the electric power system oscillation damping. The interaction between the electric power system and dynamic load after and before interference is simulated through Simulink Matlab. Dynamic load models are developed from the Hill model based on load power responses due to voltage changes. While the electric power system model is based on a model developed by Demello, which is a Single Machine Infinite Bus System. Based on the two models, an overall block diagram is made that illustrates the interaction between dynamic loads and the electric power system. The results showed that there was an increase in the stability of the electric power system with dynamic load feedback and a decrease in the rotor angle and increase in voltage. So that it can be concluded that changes in dynamic load parameters affect the stability of the electric power system. This study can be used as a basis for studying the behavior of electrical power systems that experience greater disturbance with load feedback. © Published under licence by IOP Publishing Ltd.
