This paper proposes a method to optimize AC/DC hybrid distributed energy system with power electronic transformer. First, the steady-state model of power electronic transformers under normal operation mode is established; subsequently, the model of AC/DC hybrid system containing power electronic transformers is established. The scheduling model to realize full consumption of distributed energy and economic optimization in AC/DC hybrid system is optimized. Finally, an example is used to verify the AC/DC system model with power electronic transformer. The results show that the power electronic transformer can be used in the AC/DC hybrid system, the power transfer function between the AC network and the DC network is controlled by the power regulation function of the power electronic transformer, which can effectively realize the full consumption of the distributed power generation. In addition, the application of power electronic transformer reduces the operating cost of the system and realizes the economical operation of the AC/DC hybrid system.
