Abstract – Economic Load Dispatch (ELD) is a key optimization problem used in power systems to schedule the generation such that network constraints drawn from transmission capability, generation strengths and load demands among other aspects are met efficiently and production costs incurred are minimal. As has been mentioned before, data on generator input-output curves are non-linear and non-convex; therefore, ELD is not easy for traditional optimization. For these challenges, the present work proposes advanced techniques among which are Dynamic Programming (DP), Teaching-Learning Based Optimization (TLBO), and Particle Swarm Optimization (PSO). In this research, MATLAB environment was used to perform a number of evaluations to determine the performance of these algorithms. The results also state the potential of these approaches for practical power system dispatch by demonstrating their applicability of providing approximated optimal solutions for complex ELD.
