Determination of voltage stability boundary values in electrical power systems by using the Chaotic Particle Swarm Optimization algorithm
(Elsevier Sci Ltd, 2015) Kuru, Leyla; Öztürk, Ali; Kuru, Ersen; Kandara, O.
A power system has critical values which are the limit values of voltage stability. These values are the highest active power taken by the load busses, voltage amplitude and the angle of the busses. In this research the critical values in electric power systems are defined with use of Chaotic Particle Swarm Optimization (CPSO) algorithm. In this study CPSO has been aimed to use logistic map and Henon map as chaotic maps to control the values of the parameters in velocity update formulation. Initially, critical values of voltage stability have been found by simple Particle Swarm Optimization (PSO). Then the same values have been found with CPSO. Accordingly, the results have been evaluated and observed that the stability critical values found by CPSO can be used to produce good potential solutions. Simulation results are promising and show the effectiveness of the applied approach. (C) 2014 Elsevier Ltd. All rights reserved.
