Firefly Algorithm Established Economic Load Dispatch with Loss Coefficients

Economic load dispatch (ELD) is an significant optimization assignment in power system. With this allotment of generation for each unit has been achieved effectively to minimize the generation. Generally, power system problems like ELD have difficulties during solving with general maths. Conventional methods are necessary to minimize the cost of generation, with proper allotment and the reduction of losses. It can be solved by using Newton approach, nonlinear programming, quadratic programming and so on. These techniques may be struct at local optimum. Therefore, to avoid that, in this paper, newly developed firefly algorithm has been applied on six-unit generator system. With the firefly algorithm, the obtained results are superior to other methods, and it confirms the best generator output and optimal fuel cost of the system.
