MULTI-AREA ECONOMIC DISPATCH WITH PROHIBITED OPERATING ZONES USING IMPROVED BAT ALGORITHM

This paper presents application of Improved Bat algorithm for solving Multi-area economic load dispatch problem (MAED) considering tie line constraint, transmission loss, valve point loading effect and prohibited operating zones. Improved bat algorithm is an optimization algorithm motivated by the echolocation behavior of natural bats in finding their foods. Potency of the algorithm is tested on two area system with six generating units and it is compared with artificial bee colony optimization, differential evolution, evolutionary programming and real coded genetic algorithm. The promising results show the quick convergence and effectiveness of the projected technique
