A Review: FACTS Devices for Modern Power System

Abstract

To mitigate the growing demand we require much capable transmission and distribution system. The major problem for maintain such a big network is the quality of supply with stability and reliability. Power quality means the nonstandard supply voltage, supply current and supply frequency, that results malfunctioning or failure of operation of various equipments and accessories. The major impact of poor quality of supply is on the distribution system on which the maximum load is connected.The need for more efficient electricity systems management has given rise to innovative technologies in power generation and transmission. To overcome the power quality problem of distribution system, we have number of power quality solution techniques by using FACTS controllers, which uses newly available power electronics devices.Flexible AC Transmission Systems (FACTS) is a technology that responds to these needs. This paper covers the brief survey of FACTS controllers used in modern power system.
