Optimal Configuration for Power Electronic Transformer Ports Considering the Optimization of Transfer Paths

Power electronic transformers (PET) have received widespread attention in recent years due to their flexible networking, diverse operating modes and rich control objects. In this paper, first, Considering the constraints of PET and the N-1 transfer path constraints, we established a multi-objective port capacity configuration optimization model for multi-port PET. Then, aiming at the proposed multi-objective optimization model, this paper proposes a two-layer iterative solution method to solve the proposed model. Finally, a case study is used to verify the effectiveness of the method proposed in this paper, the PET port optimization configuration method proposed in this article can reduce the dimensions of the planning model, and can solve the problems of AC/DC coordination and network-source coordination optimization.
