Firefly algorithm for economic emission dispatch with normalized objective function

The economic emission dispatch (EED) assumes a lot of significance to meet the clean energy requirements of the society and simultaneously minimizes the cost of generation. The Firefly Algorithm (FA) is a nature-inspired meta-heuristic algorithm for solving multimodal optimization problems.  This paper presents an FA based strategy for obtaining the robust solution of EED problem involving normalized objective function. The feasibility of the proposed approach is evaluated through two test systems and the results are presented to demonstrate its effectiveness.
