Multi-objective economic emission load dispatch using modified biogeography based optimization algorithm

In this article modified biogeography-based optimization (MBBO) algorithm is proposed to solve convex and non-convex combined economic and emission load dispatch (CEELD) problem of power system. Some non-linearities like transmission losses and valve point loading effects are considered. The main objective of EELD is to allocate power generation within their limits satisfying load demand where cost and emission both will be minimized. Biogeography interacts with the biological distribution of species. The proposed MBBO 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 MBBO algorithms.
