A Hybrid Approach for Economic Power Dispatch
Authors: , ,
Abstract: In this paper, a novel hybrid optimization algorithm, which combines a firefly algorithms and Artificial Bee Colony algorithm (FFA- ABC), is proposed for solving the economic power dispatch (EPD) problem. The hybrid algorithm is structured with two stages. The first stage uses the search by firefly algorithm (FFA) and second stage is a search with Artificial Bee Colony algorithm (ABC). The hybrid algorithm involves two level of optimization, namely global search by the ABC and local search by the FFA, which cooperates in a global process of optimization. It can provide more robust convergence. The proposed method is tested in standard IEEE 30 bus and IEEE 57 bus test systems. Numerical results illustrate the feasibility and potential of the proposed hybrid algorithm.
