High-powered wind turbines in the electric power system lead to a significant challenge in balancing production power and electrical power consumption caused by the winds intermittent. In this study, assessing the steady state stability limit (SSSL) in South Sulawesi system when wind turbines is penetrated the Sidrap bus using the REI-Dimo method. The method developed by Paul Dimo was later known as the Radial Equivalent Independent (REI)-Dimo to determine the stability of the system, the condition of the generator which is still stable when a disturbance or load changes occur. REI-Dimo serves to determine the Z equivalent to the generator so that a state of stability can be known. This study is conducted to determine the stability of the steady state generator in South Sulawesi system with 15 generators, 44 buses on the 150kV interconnection system. The simulation results show that the normal condition is 0.0323o, the Critical clearing angle is 111.903o, and the condition of the 100% loading of the critical clearing angle is 90.00o.

W artykule założono limit stanu trwałej stabilności SSSL w systemie w prowincji South Sulawesi. Wykorzystano metodę zaproponowana przez Paula Dimo znaną jako Radial Equivalent Independent (REI)-Dimo do określania stabilności systemu kiedy warunki pracy generatora są stabilne przy zaklóconym odbiorze.
