This work 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 simple 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.
