A modified version of the artificial bee colony (ABC) algorithm is presented in this study by including a local search technique for solving the non-convex economic power dispatch problem. Total system losses, valve-point loading effects and prohibited operating zones have been incorporated in the problem formulation. The proposed technique is validated using an IEEE benchmark system with ten thermal units. Simulation results demonstrate that the proposed optimization algorithm has better convergence characteristics in comparison with the original ABC algorithm.
