The interline power flow controller (IPFC) is one of the newest devices within the FACTS group. By utilizing this device, an enhanced controllability over independent transmission systems or those lines whose sending-end are connected to a common bus can be obtained. As an extended version of the UPFC (unified power flow controller), the IPFC appears as an excellent solution for the control of multiline systems, but it also presents its own complexities whilst operating under certain system conditions. The steady-state response and performance of a generalized IPFC controlling two independent AC systems, is in this paper evaluated. None-the-less, the study can be extended to systems having more than two transmission lines. In order to observe its dynamic behavior and simultaneously validate the previous steady-state analysis, an IPFC model was also built in the ATP program. The results obtained validated the IPFC model built and ratified its capability for controlling the power flow over the compensated transmission lines.
