Transient Stability of Inverter-Based Resources

Xiongfei Wang


The loss of synchronism (LOS) under large grid disturbances has been challenging the security and reliability of inverter-based renewable power systems. Unlike synchronous machines, there is lack of physical mechanism in inverter-based resources to maintain the synchronism. This talk will provide a design-oriented analysis on the transient (synchronization) stability of inverter-based resources. The parametric impacts of phase-locked loop and power-synchronization control loops will be discussed. Enhanced synchronization control schemes will then be presented with case studies in experiments.
