This paper presents the application of an evolutionary algorithm namely as Artificial Bee Colony (ABC) algorithm to solve Economic Dispatch (ED) problem that is known as a highly constrained non-linear optimization problem with non-convex space. The Artificial Bee Colony algorithm is a population-based optimization algorithm and one of the most recent swarm intelligence based algorithms which is inspired from the particular intelligent behavior of honey bee swarms when searching for food source. The ABC algorithm is proven its superior capabilities, such as faster convergence and better global minimum achievement. Practical ED problem in power system has non-smooth cost functions subject to various equality and inequality constraints that make the ED problem be a nonlinear and non-convex optimization problem. To show the efficiency of the proposed ABC algorithm in solving ED problem, it is applied to four test systems having non-convex solution spaces. Also, the results obtained by the ABC algorithm are compared with the recently previous approaches reported in the literature. Simulation studies show the superiority and advantages of the ABC over the other methods.
