Dynamic disturbances in the power system are caused by sudden changes in load. This condition causes the stability of the generator to be disturbed, such as the emergence of oscillations in the generator in the form of oscillations of frequency and rotor angle. Power System Stabilizer (PSS) is an additional control that can increase generator stability. To get optimal PSS performance, proper tuning of PSS parameters is needed. Optimal performance of PSS can cause the frequency response and angle of the SMIB rotor to be stable. In this study, PSO is used for optimization of PSS parameters. PSS is able to provide stability so that overshoot oscillations can be suppressed, as well as faster settling time performance for the system to reach steady state conditions. To test the reliability of the SMIB, a case study of adding and subtracting loads was used.

Contingency analysis on a 150 kV network aims to see the network's reliability against interference. Contingency is a scheme for releasing one element of the generating unit or transmission line (N-1), which will affect the performance and reliability of the electric power system. Power flow analysis in an electric power system is an analysis that reveals the performance of an electric power system and the flow for certain conditions when the system is working. The analysis was carried out using the ETAP 16.00 software. The method used was the newton raphson to calculate the load flow in the N-1 contingency condition. From the results of the study, it can be seen that the power flow occurs in each channel of the 150 kV system in the South Sulawesi system. When conducting a contingency analysis of N-1 by removing the load on the middle lane of South Sulawesi, namely Maros and Sidrap, a voltage change occurs, increasing buses experiencing critical and marginal voltage conditions. This happens because of the sudden release of essential loads, so over or under voltage appears on the bus.
