Comparative Study of Methods for Optimal Reactive Power Dispatch

Abstract

Reactive power dispatch plays a main role in order to provide good facility secure and economic operation in the power system. In a power system optimal reactive power dispatch is supported to improve the voltage profile, to reduce losses, to improve voltage stability, to reduce cost etc. This paper presents a brief literature survey of reactive power dispatch and also discusses a comparative study of conventional and evolutionary computation techniques applied for reactive power dispatch. The paper is useful for researchers for further research and study so that it can apply in the various areas of power system.
