| Abstract |
This paper introduces an approach to the modeling and simulation of instability scenarios, aiming to analyze and prevent sub-synchronous oscillations. It examines the root causes of instability observed in real-world cases and incorporates the instabilities of inverter-based resources into simulation models. The study verifies the 2007 Minnesota, 2009 Texas, and 2015 Xinjiang SSO cases. Based on MATLAB/Simulink, the simulation model refer grid structures and instability conditions of real events. The results confirm that this simulation modeling can similarly replicate the dynamic characteristics of real-world instabilities, supporting further analysis and mitigation of SSO. |
