GRAVITATIONAL SEARCH ALGORITHM FOR ECONOMIC DISPATCH WITH VALVE-POINT EFFECTS

Abstract

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 as Gravitational Search Algorithm (GSA). The proposed approach has been applied to various test systems with incremental fuel cost function taking into account the valve-point effects. The results shows that performance of the proposed approach reveal the efficiently and robustness when compared results of other optimization algorithms reported in literature.
