Abstract: The realization of the double-carbon goals requires the construction of a new power system with new energy as the main body and the integration of source, network, charge and storage. The reduction of the synchronous generators inevitably leads to the gradual reduction of inertia and damping of the power system, which further causes the problem of power stability. Virtual synchronous generator control technology (VSG) is an effective means to improve the active support capability of new energy to the power grid. In this paper, the requirements of the existing domestic new energy grid-connected standards for the VSGs to support the power grid are sorted out, the research trends and the existing achievements of the VSG are comprehensively combed, and the realization process and optimization of voltage-support and power-support-typed VSG are summarized. The equivalent relationship between the other power grid support control strategies and the VSG is established, which is unified in the VSG framework from the point of view of parameter design. Finally, the application of VSG in the new energy active power grid support is prospected.
