Absttwct: In this pape~voltage stability is evaluated b-v both dynamic P V curves and time-domain simulations, considering the combined dynamic control effects of a static compensator (SZ4TCOh!) and transformer on-load-taps (OLT). The studied system is heavily loaded at hvo locations and an 80 Mvar STA TCOM is connected to improve the voltage stability of entire s~stem for a contingency of a three-terminal line outage. The resu[ts presented in this paper: (a) show that a STA TCOM can greatly
