Sliding mode control power system stabilizer (PSS) for Single Machine Connected to Infinite Bus (SMIB)

This paper represents an alternative approach on designing PSS for a Single Machine and Infinite Bus (SMIB) system based on sliding mode control (SMC) technique. SMIB system is chosen as it is such a simple configuration which is extremely useful in understanding basic effects and concepts of PSS. In order to test the effectiveness of the proposed scheme, simulation will be carried out to analyze the small signal stability characteristics of the system about the steady state operating condition following the loss of a transmission line. For comparison, simulation of a conventional control PSS and optimal control PSS will be carried out. The main approach is focusing on the control performance which later proven to have the degree of a shorter reaching time and lower spike.
