Optimized POD in coordination with UPFC for damping of power system oscillations

This paper presents the effective control signals of Unified Power Flow Controller (UPFC) for damping of oscillations with Power Oscillation Damping Controller (POD) in Linearized Modified Phillips Heffron Model of Single Machine Infinite Bus System (SMIB). The POD parameters are optimized by using Nonlinear Control Design Blockset (NCD). The result indicate the significant improvement in damping of oscillations. Eigen value analysis validate the performance of various damping controllers.
