A Comprehensive Comparison of FACTS Devices for Enhancing Static Voltage Stability

This paper presents a comparison of FACTS devices for static voltage stability study. Various performance measures including PV curves, voltage profiles, and power losses are compared under normal and contingency conditions. Placement and sizing techniques of series FACTS devices and UPFC are proposed for loading margin enhancement. The paper provides a guide for utilities to have an appropriate choice of FACTS device for enhancing loading margin and static voltage stability.
