Abstract: Three-phase voltage inverter has good adaptability and stability in the grid-connected process, and is the key equipment for realizing energy conversion and grid-connected output in new energy system. In the traditional control mode, the control strategy of microgrid inverter virtual synchronous generator adopts voltage and current double-loop structure, which has many problems such as multiple control loops requiring multiple coordinate transformations, difficult parameter setting and limited dynamic response ability. To solve this problem, a MPVC strategy for virtual synchronous generator is proposed. Firstly, the control strategy of virtual synchronous generator is briefly described. Secondly, the space voltage vector model of inverter is established. Finally, the key control function model of inverter model predictive voltage is derived, and the MPVC control algorithm logic is analyzed. The proposed method not only simplifies the control structure and improves the dynamic response capability of the system, but also provides good voltage and frequency support for the power grid. Finally, the correctness of the proposed control method is verified by setting up simulation and experiment platform.
