To Improve Performance Response of Economic Load Dispatch by using Optimization Technique

Abstract

The power systems are grown in complexity of power demands. The focus is shifted to enhance the performance of power system, customer focus, increasing the reliability, clear power and reducing cost. Optimal system includes the economy of operation, fuel costs, system security with the aim of improving the efficiency of electric power system. The Economic load dispatch is the scheduling of power generators with respect to the load to minimize the total cost of transmission and operational costs of generating units while meeting the constraints. The objective of the ELD is to allocate the total transmission loss and total load demand among power plants while satisfying the operational constraints simultaneously. This paper presents solution for improvement of performance response of ELD by using genetic algorithm and fuzzy logic optimization approaches.
