This paper focuses on systematic approach towards damping the tie-line power oscillations in an interconnected thermal power plant using Unified Power Flow Controller (UPFC) with Variable Structure System (VSS) Controller. Conventionally, Automatic Generation Control (AGC) is carried out by primary governor control and secondary Proportional-Integral (PI) controller. PI controller helps to damp out tie-line power and frequency oscillations when subjected to unit step load disturbance. Zieglerfatcat:jpnc3d7z55cnvhwucjdbrk27uu
