Abstract: In order to sort out the influence of the virtual synchronous generators on the low-frequency oscillation of the system,and further explore its potential and application in providing damping and inertia,relevant research work has been carried out. Firstly,the research status of power system low frequency oscillation is summarized. Then,the influence of the non-synchronous machine power supply on the low-frequency oscillation is summarized and analyzed. Finally,the influence of the virtual synchronous generators with non-synchronous power supply on the low-frequency oscillation of the system is summarized,in view of the key problems that need to be solved urgently in the application of virtual synchronous generators in new power system,the further prospect and thinking are put forward.
