The Interline Power Flow Controller (IPFC) is one of the Voltage Source Converter (VSC) based FACTS controllers which can effectively manage the power flow via multi line transmission system. In this paper a new method for control of IPFC, with the aim of managing the power flow in transmission lines, is presented. Simplicity and fast system response are two characteristics of this method. An IPFC with the presented control method is simulated. The results of this simulation demonstrate the success of the method.
