Abstract—The article presents Biogeography-Based Optimization (BBO) algorithm which is applied on convex and non-convex Economic Load Dispatch (ELD) problem of power system. In this article transmission losses are not included. In this method, some non-linearities like valve point loading effect are considered. The primary objective of ELD is to determine optimal power allocation within operating limits such that the power demand is satisfied. Biogeography interacts with the biological distribution of species. The proposed BBO algorithm has been tested on three different test systems considering equality and inequality constraints. The results are checked the convergence characteristics with other techniques which prove the advantage of the proposed BBO algorithms.
