This Paper proposes a Firefly Algorithm for solving an Economic Dispatch (ED) problem. It is the most important problem in power system operation and control. Its objective is to determine the optimal combination of power outputs of all generating units in order to minimize the total cost satisfying constraints and load demand in each interval. Several conventional and evolutionary algorithms have been employed to solve this problem. The results obtained by the proposed algorithm have been compared with Genetic Algorithm (GA), Evolutionary Programming (EP) and Gradient Search Algorithm (GSA) is already available in literature. The feasibility of the proposed algorithm was verified with IEEE 30 bus system.
