Investigation of the best placement for voltage stability by STATCOM

The study is related to the identification of optimal point for Static Synchronous Compensator (STATCOM) for static voltage stability. The study undertaken in IEEE 14 buses systems utilized analysis for relationships in voltage maximum loading parameters of STATCOM placed between lines and analysis for change in the bus voltage. Maximum loading parameter values obtained for each line and the improvements in weak buses that provided the best results were given in tables and figures. The results of the study show that STATCOM improves the voltage instability cases that can occur in optimal place selection.
