A Review on Voltage Stability and Power Quality Improvement by using UPFC Controller

Load demand is growing rapidly these days, necessitating an increase in generating capacity to satisfy that demand. Voltage instability arises as a result of external and internal imbalance, causing the bus voltage to fluctuate. The Unified Power Flow Controller UPFC is a FACTS device that is used to maintain steady voltage and enhance power flow in transmission lines. This article examines the use of UPFC to manage both active and reactive power and compares it to other FACTS devices. In comparison to other FACTS devices such as STATCOM, which controls only voltage, TCSC, and SVC, which controls only impedance, UPFC is one of the most promising FACTS devices because it can control phase angle, voltage magnitude, impedance, and various line parameters selectively or simultaneously. It also goes over the UPFC topology in transmission lines in depth.
