The Effect of an Interline Power Flow Controller (IPFC) on Damping Inter-area Oscillations in Interconnected Power Systems

The effect of an interline power flow controller (ipfc) on damping low frequency oscillations has been implied in some papers, but has not been investigated in detail. this paper investigates the damping control function of an interline power flow controller installed in a power system. for this purpose, a single machine-infinite bus model, integrated with ipfc, is used and the linearized model is established. using this model, the phillips-heffron model of the system for steady state digital simulations is derived. in this paper, the numerical results are presented using the matlab simulink toolbox, which shows the significant effect of ipfc on damping inter-area oscillations.
