Power flow management by IPFC in transmission system

Interline Power Flow Controller (IPFC) is one of the newest FACTS (Flexible AC Transmission Systems) devices. This controller can simultaneously control power flow of multiple lines. In this paper IPFC converters are considered as hypothesis bus in the power flow equations and then are matched with the Newton power flow, a program in MATLAB has been written oder to extend conventional NR algoritm based on this model. A case study is conducted on 6-bus & 3-machine and 30-bus & 6-machine systems, and the results are examined in the absence and presence of IPFC in the network. This represented with two VSC in the case study. The numerical results of this study show the capability of this tool in controlling the power flow in power system.
