Title: Economic Load Dispatch with Piecewise Quadratic Cost Function Using Evolutionary Computations
Abstract: This paper presents evolutionary computations to solve the problems of economic load dispatch (ELD) with single quadratic cost functions and piecewise quadratic cost functions. Genetic algorithms (GAs), evolution strategies (ESs) and evolutionary programming (EP) are applied to the ELD problems. To improve these methods in nonlinear optimization problems, two hybrid optimization methods exploiting the advantages of each evolutionary computations are developed. Optimization methods combining GA with ES, and EP with ES are tested in the ELD problem with piecewise quadratic cost functions. Case studies illustrate the superiority of the proposed methods to existing numerical methods.
