Abstract: The Economic Load Dispatch (ELD) problems in power generation systems is to reduce the fuel cost by reducing the total cost for the generation of electric power. This paper presents a Novel TANAN’s Algorithm (NTA) for solving ELD Problems. The main objective of NTA is to minimize the total fuel cost of the generating units subjected to limits on generator true power output, power loss. The NTA is a simple numerical random search approach based on a parabolic TANAN function. This paper presents an application of NTA to ELD problems for different IEEE standard test systems. ELD is applied and compared with various optimization techniques and the simulation results show that the proposed algorithm outperforms previous optimization methods.
