In the independent micro grid system, the generator set and the new energy grid connected inverter are both important components of the system. To solve the problem of stability of the parallel of the inverter and synchronous generator, this paper studied the droop control and the virtual synchronous machine control principle, analyzed their similarities and differences and essential characteristics; established the small signal model of the parallel system of the inverter generator set, analyzed the stability of different structural systems. It Comed to conclusion that the stability of the virtual synchronous machine control in the parallel system was stronger, and the system simulation model was built by Matlab / Simulink software to verify the theoretical analysis results.
