Research on the structures and application scenarios of medium voltage AC-DC hybrid distribution network

AC-DC hybrid distribution network refers to the distribution network with AC-DC conversion power electronic devices such as converters and inverters. Compared with the traditional AC distribution network, AC-DC hybrid distribution network is more suitable to connect high penetration DGs and DC loads. This paper summarized the advantages and typical structures of medium voltage AC-DC hybrid distribution network along with their characteristics, then the application scenarios of medium voltage AC-DC distribution network are categorized and their suitable structures are analyzed.
