Low Frequency Oscillation Analysis of VSG Grid-Connected System

2021 3rd Asia Energy and Electrical Engineering Symposium (AEEES), 2021
Due to that VSG (virtual synchronous generator) simulates the operation characteristics of SG (synchronous generator), similar stability issue that is common in traditional power system may also exist in VSG grid-connected system.

Real-time low-frequency oscillations monitoring

Journal of Renewable and Sustainable Energy, 2021
A major concern for interconnected power grid systems is low-frequency oscillation, which limits the scalability and transmission capacity of power systems. Undamped or poorly damped oscillations will lead to undesirable conditions or even a catastrophic system blackout.
