Abstract As an effective way for renewable energy to access the power grid, microgrid has attracted more and more attention. Distributed generations in microgrid mostly need to be connected to the grid through inverters. However, the traditional control algorithm only considers the response speed and accuracy, and does not have the inertia characteristics similar to synchronous generators, so it will bring great impact on the power grid. In order to increase the inertia of new energy resources based on inverter interface for maintaining power system stability, this paper draws lessons from the rotor motion equation, frequency modulation characteristics and reactive power regulation characteristics of synchronous generators. A control strategy of T-type three-level energy storage inverter based on virtual synchronous generator (VSG) is proposed. Finally, the effectiveness of the proposed control strategy is verified by using the simulation platform of Matlab/Simulink.
