In this paper, a distributed energy resource (DER) optimal scheduling method for AC/DC hybrid systems with power electronic transformer (PET) is proposed. Firstly, a PET scheduling model considering loss is established. Secondly, an optimal scheduling model of the AC/DC hybrid system with PET is established. Finally, the optimal scheduling model of the AC/DC system with PET is verified by a case and the effect of PET efficiency on the operating state of the system is discussed. The results show that using the power regulation ability of PET, the distributed generation can be fully absorbed and the operating cost of the system can be reduced.
