Greater demands have been imposed on the transmission network in recent years, and these demands will continue to rise as the number of non-utility generators grows, as will rivalry among utilities. This is compounded by the fact that obtaining new rights of way is very complicated. Increased transmission demands, a lack of long-term planning, and the need to provide open access to generating companies and customers have all contributed to a decrease in supply security and quality. FACTS technology is critical for addressing some, but not all, of these issues by allowing utilities to get the most out of their transmission infrastructure while still improving grid stability. However, much of the capacity enhancement requirements would necessitate the construction of new lines or the upgrade of current and voltage capability. This paper has presented a review of different technology for thyristor voltage regulator (TVR) for transmission line power flow control and voltage profile control. The different technologies is presented and discuss like Automatic voltage restorer, Switched capacitor voltage regulator, Series voltage regulator, teaching-learning based AVR, integrated voltage regulator and D-STATCOM.
