SMC based power oscillation damping controller for SSSC connected network

This paper presents the algorithm for interfacing Voltage Sourced Inverter (VSI) based Static Synclironous Source Series Compensator (SSSC) with power system for enhancement of transient stability. The differential equations are solved by implicit integration method which is numerically stable. A standard 9 bus system is considered for analysis. The effectiveness of the sliding mode controller (SMC) over the conventional PI controller for SSSC in improving transient stability is illustrated.
