In recent years, various heuristic optimization
methods have been proposed to solve economic dispatch
(ED) problem in power systems. This paper presents the
well-known power system ED problem solution considering valve-point effect by a new optimization algorithm
called artificial bee colony (ABC). The proposed approach
has been applied to various test systems with incremental
fuel cost function, taking into account the valve-point
effects. The results show that the proposed approach is
efficient and robust when compared with other optimization algorithms reported in literature.
