In this paper, a new method based on “Brent Approach” for the solution of Non linear Economic Dispatch Problem, with transmission losses, having quadratic fuel cost functions is presented. In the present approach the qualitative solution can be achieved with less computational time and it converges within the few iterations. The algorithm involves selection of lambda values then the optimal lambda value is evaluated from the power balance equation by Brent method. The proposed algorithm has be tested on power system having 3, 6 and 15 generating units using MATLAB and Simulation results compared with the Genetic Algorithm approach.
