ABC algorithm with local search applied to Economic Dispatch Problem

Abstract

In this paper, to solve the problem of non-convex economic power system, a detailed study is presented of an improved version of the artificial bee colony (ABC) approach including a local search technique. Prohibited operating zones, valve-point loading effects and total powers transmission losses have been incorporated into the formulation of the problem. An IEEE reference system with ten thermal units was used to validate the proposed technique. Better convergence characteristics compared to the original ABC algorithm have been demonstrated by the simulation results.
