    The topology of energy storage inverter is adopted with T-type three-level structure. The characteristics are analysed when the T-type three-level energy storage inverter is working on the grid-connected and isolated-island operation. In order to satisfy the stable switching operation from grid-connected to isolated-island, a seamless switching control strategy based on the virtual synchronous generator is proposed. A simulation model of seamless switching control for T-type three-level energy storage converter is built in MATLAB to verify the correctness of the proposed strategy.
