Mathematical modelling, analysis and effects of interline power flow controller (IPFC) parameters in power flow studies

An advanced and versatile member of flexible AC transmission systems (FACTS) controller is interline power flow controller (IPFC). In general, IPFC is used in multiple transmission lines of a power system network. This paper presents a power injection model of IPFC. The power injection model is incorporated in Newton-Raphson (NR) power flow solution method to study the effects of IPFC parameters in power flow studies. A program in MATLAB has been written in order to extend conventional NR algorithm based on this model. Numerical results are carried out on IEEE 14-bus system to demonstrate the performance of the IPFC model. It is shown that there is a possibility of regulating bus voltages, active power flow, reactive power flow and minimizing the power losses simultaneously with proper IPFC parameters.
