To provide inertia and damping for the system and to improve the stability of voltage and frequency in independent micro-grid, Virtual Synchronous Generator (VSG) control strategy of inverters is recommended, which mimics synchronous generators. However, the traditional VSG parallel system is challenged by rational distribution of reactive power and DC suppression. Firstly, the accurate power sharing mechanism of VSG is analyzed based on the principle of VSG. Besides, an improved reactive power control method is proposed from the angle of voltage compensation to construct the integrator, which can realize the decoupling of reactive power distribution and line impedance. Furthermore, the double loop control is redesigned to suppress the DC by using the quasi resonant controller. At the same time, the method of parameter matching is studied to ensure the accurate power sharing of VSG. Finally, the validity and effectiveness of the proposed VSG control are verified by Matlab simulation.
