Christos Drosos, Ioannis Trichas, Aristidis Vlachos . Solution of Economic Load Dispatch (ELD) Problem by Path Relinking (PR) Algorithm. International Journal of Computer Applications. 145, 3 ( Jul 2016), 41-44. DOI=10.5120/ijca2016910522
This paper presents a solution of the Economic Load Dispatch (ELD) problem, using the Path Relinking Algorithm (PR). Generally, PR is a population-based meta-heuristic technique to integrate intensification and diversification strategies in a search procedure. Also, to explore trajectories that connect elite solutions .The economic load dispatch problem is formulated as the minimization of the production cost function, expressed as a quadratic polynomial, subject to the power balance constraints and to the generation limits constraints. The proposed approach has been applied in five generators units. The comparison with the real-coded genetic algorithm (RCGAs), the binary-coded genetic algorithm (BCGAs) and the classical optimization technique of Quasi-Newton, demonstrates the superiority of the PR algorithm and confirms its potential to solve the ELD problem.
