Abstract
The problem of small signal stability is one of the main problems in the current power system because the purpose of operating the system is close to the limit. Small signal stability is important because small disturbances in the form of non-dampened electromechanical oscillations have limited the power flow limit in a steady state, so the oscillation will affect the operating system in a security and quality review. The entry of renewable energy in the Sulawesi interconnection system certainly has an impact on system stability and the emergence of electromechanical oscillations. An estimated 75 MW of power will come from the PLTB that will be built in Sidrap and 62.5 MW in Jeneponto. This study aims to analyze small signal stability due to the development of EBT generators on the Sulawesi interconnection system through eigenvalue characteristics and participation factors. The PLTB that will be integrated in the Sulawesi system certainly affects power flow which has an impact on small signal stability. From the above explanation, it is considered necessary to conduct research on the analysis of the stability of small signals before and after the integrated power plant in the Sulawesi electricity system.
