主　　题：Virtual machine interlinking converter unified control microgrid. 

摘      要：The equilibrium between dc bus voltage and ac bus frequency(Udc-f equilibrium)is the algorithm core of unified control strategies for ac-dc interlinking converters(ILCs),because the equilibrium implements certain ***,what the mechanism is has not been explicitly explored,which hinders further studies on unified *** paper reveals that the state-space model of a Udc-f equilibrium controlled ILC is highly similar to that of a shaft-to-shaft machines *** a detailed mechanism is dis-covered and named“virtual shaft-to-shaft machine(VSSM)mechanism.A significant feature of VSSM mechanism is self-synchro-nization without current sampling or ac voltage sampling.
