Particle Swarm Optimization Applied To Economic Load Dispatch Problem

Abstract

The economic load dispatch problem is one of the major optimization problems in the electric power system. The main objective of this problem is to reduce or minimize the total operational cost of the system fulfilling the load demand within the limit of constraints. In this work, a more general heuristic method known as Particle swarm optimization (PSO) is applied to solve the economic load dispatch problem in electric power system. IEEE-14 bus system for 3-unit is considered to test the algorithm with cost function. This method is simple, direct, relatively new, modern, reliable and powerful optimization method that has been empirically shown to perform well on many of these optimization problems. It is widely used to give the global optimum solution in a complex search space.
