Abstract:

In this paper, a solution has given to solve optimal power flow problems. An integrated approachwith the combination of artificial bee colony (ABC) algorithm and artificial neural network (ANN) is proposed as a solution. The main aim of selecting ABC algorithm is to maintain the fuel cost and the emission of the power generation system economically and to optimize the optimal operating range of generation limits. A swarm intelligence optimization algorithm like ABC algorithm is based on the intelligent foraging behavior of honey bee swarm. ANN is technique from artificial intelligence (AI) which is used to incorporate for determining the optimal injected voltage magnitude and voltage angle of Unified Power Flow Controller (UPFC). The power flow parameters are evaluated using the proposed integrated OPF technique. The proposed integrated technique has been examined and tested on IEEE-57 bus system. Test results show that the proposed integrated approach can obtain better solution than other intelligent techniques and classical method.
