An integrated approach for solving optimal power flow problem is considered in this paper. The proposed integrated technique is the combination of artificial bee colony (ABC) algorithm and artificial neural network (ANN). The intention of selecting ABC algorithm is to optimize the optimal operating range of generation limits and to maintain the fuel cost and the emission of the power generation system economically. ABC algorithm is an optimization algorithm, based on the intelligent foraging behavior of honey bee swarm. ANN is incorporated for determining the optimal injected voltage magnitude and voltage angle of Unified Power Flow Controller (UPFC). Using the proposed integrated OPF technique, the power flow parameters are evaluated. The proposed integrated technique has been examined and tested on IEEE 14 bus system. Test results indicate that the proposed integrated approach can obtain better solution than other intelligent techniques and classical method.
