The results shown the operation time in 9 bus test
system. It gave the best results when compare with QuasiNewton and particle swarm optimization. The minimum time operation of Quasi-Newton (BFGS) is 0.3589, particle swarm optimization (PSO) is 0.7959 and artificial bees colony (ABC) is 0.4359. However, when considering the average operation time, the artificial bee colony is least operation time of 0.4515. The standard deviations of QuasiNewton (BFGS) is 64.8504, particle swarm optimization (PSO) is 2.6800 and artificial bees colony (ABC) is 0.0089. The artificial bee colony were least CPU time when compared other method.
