Potential Competitive over Resources (COR) optimization method to solve economic load dispatch problem

Abstract

This paper proposes a new method namely Competitive over Resources (COR) optimization algorithm to solve the economy load dispatch (ELD) problem which has the ability to search for a global optimum by considering the operating constraints of the generating units. Similar to many of the recent heuristic optimization techniques based on the behavior of physical or biological systems in nature, the proposed COR optimization method is generally a new evolutionary algorithm inspired by animal behavior competing to finding food resources. In natural competition, the animal in any group will search for the area with abundant food sources. The group that succeeds in locating the abundant food supply experiences an increase in the population and thus exhibits fast convergence toward optimal results. In order to evaluate the performance of the COR algorithm, two standard ELD test systems with considerable constraints have been tested and compared with other published ELD problem using basic heuristic algorithm. Applying the proposed algorithm on ELD function shows its capability to converge nearer to the optimum solution compared to other determined optimization methods.
