Biogeography Based Optimization to solve economic load dispatch considering valve point effects

This paper presents Biogeography Based Optimization (BBO) technique for solving constrained economic dispatch problems in power system, Considering valve point nonlinearities of generators. In this paper, two ELD problems of different characteristics have been used to investigate the effectiveness of the proposed algorithm A comparison of simulation results reveals that the proposed algorithm is better than, or at least comparable to other well established algorithms in terms of the quality of the solution.
