Performance Analysis of Various Soft Computational Techniques for Economic Load Dispatch
Abstract
A good practice is the one in which the product cost is minimized without scarifying the quality. The main aim of ELD is to minimize the production cost. Economic operation strategy those are required to maintain the power dispatch economically. Now day’s limitation of energy resources, high power generation cost, and increasing demand for electrical energy requires optimal economic dispatch. The main idea is that in order to serve load at minimum total cost, the set of generators with the lowest marginal costs must be used first, with the marginal cost of the final generator needed to meet load setting the system marginal cost. This is the cost of delivering one additional MW of energy onto the system. This paper reflects the effectiveness and reliability of Particle Swarn Optimization (PSO) over convectional mathematical model Lamdda Iteration, which has been carried out for 3 bus and 6 bus generator systems. We also have compared the fuel cost (effective) computation with Particle Swarn Optimization (PSO) over Lamdda Iteration and Genetic Algorithm (GA) optimization. The results obtained using Particle Swarn Optimization (PSO) is found to be encouraging over conventional techniques.
