This paper deals with the Optimal Power Flow (OPF) problem. Two different objective functions namely; active power losses and generation fuel cost are minimized and compared using the IEEE 30-bus system. System operating constrains, including constrains dictated by the electrical network are satisfied. An efficient software package based on the particle swarm algorithm to solve the OPF problem is developed. Comparisons between results of different objective functions and other methods in the literature are presented. Further objective functions and constraints can be easily added to the developed software package and tested.
