Abstract: With the growth of complex electrical power networks, the use of FACTS(Flexible Alternating Current Transmission System) devices has also increased in Power system. Increased demands on transmission, absence of long term planning, and the need to provide open access to generating companies and customers, all together have created tendencies towards less security and reduced quality of supply. Static Synchronous Series Compensator(SSSC) and Dynamic Voltage Restorer(DVR) are two important devices to mitigate these problems. Even though the role of these two devices in power system has been studied by many resercherer, a comparison between the two is not found much in literature. In this paper, a describtion of the two devices with their control strategies and a comparison between the two is presented.
