The main purpose of this paper is to investigate power flow regulating capabilities of an UPFC's injection model by using all three UPFC's control parameters simultaneously. The control system of the model is developed and its contributions to power flow regulation are explored on a multi-machine test system. The analysis is carried out from dynamic aspect utilising time-domain simulations. With the UPFC being embedded in the system, the analysis is concentrated on a transmission system
