Application of Intelligent Technique for Economic Load Dispatch For Power System:A Review

ABSTRACT This paper presents the application of the intelligent technique for the economic dispatch of the thermal units. The objective function considered in this paper is the minimization of fuel cost which is the non-convex optimization problem. The conventional lambda iteration method and Particle swarm optimization (PSO) technique was successfully applied to three and six unit thermal plant system. The proposed intelligent method provides the simple approach for implementation even if the number of generating units is more. The PSO method is implemented for different set of population size and the obtained results are compared with the results of conventional Lambda iteration method and other published work.
