Solving economic load dispatch problem using vortex search algorithm

Abstract

The Vortex Search (VS) algorithmis a recently developed metaheuristic algorithm inspired by a vortex pattern which can be modeled as a number of the nested circles. This algorithm basically adjusts step sizes automatically according to changed values of the radius of circles to improve solutions. In this work, the VS algorithm is applied to solve the economic load dispatch (ELD) problem in the 20-unit test system by considering the system constraints and also the performance of this algorithm has been analyzed in terms of total generation costs and power losses. Simulation results have been compared to the different algorithms used before in the literature. The obtained results demonstrate that VS algorithm is capable of solving the ELD minimization problem efficiently and finding the output power of all the generation units properly.
