Dynamic modeling of Interline Power Flow Controller for small signal stability

This paper addresses the formulation of the nonlinear dynamic model of the power system installed with Interline Power Flow Controller (IPFC). The linearized model for both single-machine infinite-bus and multi-machine power system installed with IPFC is developed and incorporated into the Phillips-Heffron model. These models lay the foundation for small signal stability studies of the power system using IPFC. The application of the models is demonstrated for a Multi-machine power system.
