This paper presents a new approach for solving Economic Load Dispatch (ELD) problem with generator constraints and transmission losses. Constrained Globalized Nelder Mead (CGNM) is a new proposed algorithm for solving economic dispatch problem with and without valve point effects. Convex and Non-convex cost functions with equality and inequality constraints are difficult to optimize. To circumvent these problems, a robust global technique is desirable. In this paper, Constrained Globalized Nelder Mead is proposed to optimize Economic Load Dispatch (ELD) problem globally using Variance Variable Probability (VVP). To validate the proficiency of proposed approach, statistical studies have been accomplished for different test systems of Static Economic Dispatch (ED) that is 3-unit convex and non-convex systems without losses 6-unit convex system with losses, 13-unit non-convex systems without losses and 20-unit non-convex system without losses. Also, proposed model proficiency is verified by applying it on Dynamic Economic Dispatch for test systems that is 3-unit convex system with no losses and 5-unit non-convex system with losses. Comparison of proposed algorithm with other optimization algorithms, reported in literature depicts that proposed algorithm is quite robust.
