“…To make the comparisons, the MGA [18], PSO [20], ICA [23], and the proposed PSOICA are considered to calculate their cost function. The parameters of three algorithms are set as follows: for Figure 3a shows the moving steps of the conventional ICA [20,22] when all the colony countries are assimilated by their imperialist, and the imperialist never moves.…”

“…The research presented in references [21,22] has proved the ascendency of the ICA in rate and speed of convergence. The contribution described in reference [23] is the first attempt to apply the ICA to solve the SHEPWM of power converters. It has been proved that this conventional ICA algorithm can solve nonlinear equations when the dimension of the variable is low.…”

The traditional intelligent algorithms for the selected harmonic elimination pulse-width modulation (SHEPWM) of multilevel converters provide low convergent rate and low accuracy of solutions when solving quarter-wave symmetry nonlinear equations. To obviate this problem and obtain a better modulating performance, an improved imperialist competition algorithm is proposed. The proposed algorithm enhances the global search ability by using moving imperialists. Also, a novel type of particles, named independent countries, are proposed to help the algorithm jump out of the local optimum. These independent countries change their positions using swarm intelligence. Compared with the existing particle swarm algorithm and genetic algorithm, the proposed algorithm has significant advantages by improving the accuracy of solutions and the rate of convergence. Finally, the correctness and effectiveness of the proposed algorithm are verified and evaluated by simulation and experimental results.

In this paper, the designing problem of two flexible AC transmission systems (FACTS)-based stabilizers are formulated for a cuckoo optimization algorithm (COA) with an objective function that includes the damping factor and the damping ratio of oscillations. This new optimization algorithm has a strong ability to find the most optimistic results for dynamic stability improvement. Also, its performance in 20 times run is the same as in 1 time run. Single machine infinite bus (SMIB) system has been considered to examine the operation of proposed COA based static synchronous series compensator (SSSC) and static synchronous compensator (STATCOM) controllers. Sudden change in the input power of generator is considered as a disturbance. The effectiveness of the proposed COA based SSSC and STATCOM controller for damping of low frequency oscillations is tested on a weakly connected power system with a disturbance and different loading conditions and their results are compared with each other. The eigenvalue analysis and time domain simulation results are presented to show the effectiveness of these FACTS-based stabilizers. The results obtained revealed the effectiveness of SSSC in comparison with STATCOM in damping power system oscillation and the results confirmed the effectiveness of the COA method for controller parameter optimization.
