This paper presents a theoretical study into the influence of closed-loop control of ac power flow on the small signal and transient stability characteristics of a single-generator study system. Both the constant power and constant angle modes of power flow control are examined for a range of controller response times. The results indicate that the effect of a power flow controller on system stability is dependent on both the mode of the controller and its response time. Copyright © 2004 IEEE.
