Power flow analysis in the presence of Power Injection Model of IPFC

The latest development of Convertible Static Compensators (CSC) drives the importance of the Flexible AC Transmission System controllers to higher levels because of their controllable nature and effective power flow management of multi-line systems. To realize the effect of CSC on a given power system Interline Power Flow Controller (IPFC) is considered and Power Injection Model (PIM) for the same device is proposed in this paper. The comfort in mathematical modeling and the incorporation procedure in Newton-Raphson load flow with PIM increase its importance. In this paper, proper location to install device using contingency analysis is discussed. Numerical results without and with IPFC for the variation of device control parameters is presented. The obtained results show the performance of the proposed IPFC model.
