摘要：Problem statement: Implementation of an Effective Biogeography Based Algorithm (EBBO) for Economic Load Dispatch (ELD) problems in power system in order to obtain optimal economic dispatch with minimum generation cost. Approach: A viable methodology has been implemented for a 20 unit generator system to minimize the fuel cost function considering the transmission loss and system operating limit constraints and is compared with other approaches such as BBO, Lambda Iteration and Hopfield Model. Results: Proposed algorithm has been applied to ELD problems for verifying its feasibility and the comparison of results are tabulated and pictorial visualization for convergence of EBBO is represented. Conclusion: Comparing with the other existing techniques, the EBBO gives better result by considering the quality of the solution obtained. This method could be an alternative approach for solving the ELD problems in practical power system.
