Abstract: This paper presents the application of Genetic Algorithm to solve the economic load dispatch problem of the power system. Economic Load Dispatch is one of the major optimization problems dealing with the modern power system .The objective of Economic Load Dispatch is sharing the power demand among the online generators while keeping the minimum cost generation as constraint. The aim of this paper is to operate the economic load dispatch problems of power system while meeting the total load plus transmission line losses within generation limits .This work aims in modeling the economic load dispatch problem with transmission loss and is being applied to 3 generator and 6 generator system using MATLAB.

Keywords: Economic Load Dispatch (ELD), Genetic Algorithm (GA), Fuel cost.
