A New Hybrid Shuffled Frog Leaping Algorithm to Solve Non-convex Economic Load Dispatch Problem

This paper presents a New Hybrid Shuffled Frog Leaping (NHSFL) algorithm applied to solve Economic Load Dispatch (ELD) problem. Practical ELD has non-convex cost function and various equality and inequality constraints that convert the ELD problem as a nonlinear، non-convex and non-smooth optimization problem. In this paper، a new frog leaping rule is proposed to improve the local exploration and the performance of the conventional SFL algorithm. Also a genetic mutation operator is used for the creation of new frogs instead of random frog creation that improves the convergence. To show the efficiency of the proposed approach، the non-convex ELD problem is solved using conventional SFL and an improved SFL method proposed by other researchers. Then the results of SFL methods are compared to the results obtained by the proposed NHSFL algorithm. Simulation studies show that the results obtained by NHSFL are more effective and better compared with these algorithms.
