| Popis: | Development of power electronics transformers (PETs) has made dc distribution and hybrid ac/dc systems a competitive solution for future network expansion. This study focuses on the functions of a multiport PET interfacing medium-voltage and low-voltage networks. A comprehensive power flow control scheme based on a globalised multiport transmission model of the PET and droop control is derived. This allows for a coordinated energy exchange between the ports of the PET, which enables autonomous operation. Simulations of the proposed approach in a hybrid ac/dc distribution network with different levels of distributed generation and loads verify the effectiveness of the method. |
