TITLE

An Intelligent Voltage Control System for Large Scale Power System

pdf PDF

ABSTRACT

In many developed countries, voltage and reactive power control system suitable for the domestic power system is operated in order to secure the voltage stability depending on the reactive power. Recently, Korea power system has been operated more closely to stability limits in state heavy-load because of growth in load-demand and reactive power loss have been increased due to the installation of long-distance transmission lines, since the power plants are located far from load-demand regions. For this reason, intelligent voltage control system has been proposed to maintain voltage stability in Jeju power system, Korea. This paper presents the application of the developed intelligent voltage control system to the Korean power system with dense structure and check up on various issues that needs to be applied to large scale power systems.
