In this paper, the authors present the use of an advanced and versatile member of Flexible Alternating Current Transmission Systems (FACTSs) device which is Interline Power Flow Controller (IPFC) to improve the Available Transfer Capability (ATC). In general, IPFC is used in multiple transmission lines of a power system network. A mathematical model of IPFC, termed as Power Injection Model (PIM) is derived. A program in Matlab has been written in order to extend Repeated Power Flow (RPF) method based on this model for ATC enhancement.
