چکیده
This paper investigates the ability of Immune Algorithm (IA) in designing a supplementary controller for Static Var Compensators (SVC) to damp the power system inter-area oscillation. For this the parameters of the supplementary controller are determined by IA using an eigenvalue-based objective function. The numerical results are presented on a 2-area 4-machine system to illustrate the feasibility of the proposed method. Also, to compare the results obtained by IA, a simple Genetic Algorithm (GA) is applied. Furthermore, to validate the designed controllers by IA and GA a supplementary controller is designed by H∞ controller using loop shaping method. To show the effectiveness of the designed controllers, a three phase fault is applied at a bus. The simulation study shows that the designed controllers improve the stability of the system.

Design Supplementary Controller Based on Stabilizing Effect of Delay for Damping Inter Area Oscillations in a Power System
The delay associated with signal transmission through the wide-area measurement system reduces the functionality of the power oscillation damping control system. One of the important issues is the poor operation of the supplementary controller against delay existence, which limits the efficiency of damping of ancillary equipment, such as SVCs in a power system. This paper as a solution proposes...
