ECONOMIC LOAD DISPATCH PROBLEM WITH VALVE POINT EFFECT USING FIREFLY ALGORITHM

This paper proposes application of Firefly algorithm for solving economic load dispatch problem with valve point effect. Firefly algorithm is a metaheuristic population based method which was based on the flashing patterns and behaviour of fireflies. The proposed approach has been examined and tested with the numerical results of economic load dispatch problems with three and five generating units with valve point loading without considering prohibited operating zones and ramp rate limits. The results of the proposed Firefly algorithm are compared with that of other techniques such as lambda iteration and ABC.
