Economic Emission Load Dispatch with Multiple Fuel Options Using Cuckoo Search Algorithm with Gaussian and Cauchy Distributions

Abstract

Cuckoo Search Algorithm (CSA), a new meta-heuristic algorithm based on natural phenomenon of Cuckoo species and Lévy flights random walk, has been successfully applied to several optimization problems so far. In the paper two modified versions of CSA, where new solutions are generated using two distributions including Gaussian and Cauchy distributions are proposed for economic emission load dispatch (EELD) problem with multiple fuel options. The advantages of CSA with Gaussian distribution (CSA-Gauss) and CSA with Cauchy distribution (CSA-Cauchy) over CSA with Lévy distribution are fewer parameters and fewer equations and shorter computational process. The proposed method is tested on one test system consisting of ten generating units with various load demands and compared to other methods. In addition, the best compromise from the set of obtained solutions is found and compared to this from lamda-iteration (LI) method and Hopfield Lagrange Network (HLN). The result comparisons have indicated that the proposed method is a highly effective method.

Optimization techniques for economic load dispatch problem in power plant

“…Sang Dang Ho et al propose a Cuckoo Search Algorithm with Cauchy distribution and Gaussian distribution, which have been combined for solving economic emission load dispatch problem with multiple fuel options. The advantages of the methods it uses few parameter and high success rate [27]. Luo, et al reduce the total costs using set of quasi-linear equations, resulting in a solution form similar to that of an electric network.…”

A novel version of Cuckoo search algorithm for solving optimization problems

“…Marichelvam, Prabaharan, and Yang (2014) developed a new heuristic, namely NEH combined with an improved CS to solve the realindustrial scheduling problem. Ho, Vo, Le, and Nguyen (2014) used two distribution, including Cauchy and Gaussian distributions for solving the economic emission load dispatch problem with multiple fuel options. The proposed CS was achieved better cost computational processes when compared to Lévy CS.…”

Cuckoo Search Algorithm Optimization Approaches for Solving Economic Load Dispatch: A Review

“…It is modelled in such a way that the power generated with the plants' constant coefficients are represented using quadratic polynomial function [13]. The fuel cost curve of non-convex ELD is smooth convex while convex ELD has non-smooth (non-linear cost curves)fuel cost due to the inclusion of the above peculiar characteristics of a thermal generator [14,15]. ELD problem can be solved either by ignoring transmission loss or inclusion of transmission losses [16][17][18].…”
