Study of FACTS Device Applications for the 220kV Southwest Region of the Vietnam Power System

This paper presents a study of FACTS devices applications, in particularly choice of adequate shunt compensators (type of FACTS devices, location) in order to improve voltage and transient angle stability. The study is carried out for the 500kV Southern Vietnam power system in 2020 with a high load scenario. The load flow calculation, P-V curve analysis and transient stability study are examined by using the PSS/E-33 software. The obtained results show that with the application of FACTS devices, voltage stability and transient angle stability of this power system are considerably improved.
