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.
