In this paper, controls of electro-mechanical inter-area oscillations between interconnected power regions are studied. If small amplitude oscillations with low-frequency in power systems do not damp as needed, these oscillations can cause instability of power systems by limiting the system's power transmission capacity. Many control methods have been applied to interconnected systems so far. In this study, a PID controller with derivative filter for damping the inter-area oscillations is designed by Coefficient Diagram Method (CDM) parameters. Time response performances of several previous control methods, such as the derivative filter PID controller, an optimization PID controller model that was developed using MATLAB/Simulink, and the controller designed using CDM are compared. Simulation results show that the CDM-based controller is more successful than the other controllers in damping the inter-area oscillations in power systems.
