摘　　要：The integration of converter-interfaced generators(CIGs)into power systems is rapidly replacing traditional synchronous machines.To ensure the security of power supply,modern power systems require the application of grid-forming technologies.This study presents a systematic small-signal analysis procedure to assess the synchronization stability of gridforming virtual synchronous generators(VSGs)considering the power system characteristics.Specifically,this procedure offers guidance in tuning controller gains to enhance stability.It is applied to six different grid-forming VSGs and experimentally tested to validate the theoretical analysis.This study concludes with key findings and a discussion on the suitability of the analyzed grid-forming VSGs based on the power system characteristics.
