Earthing Systems of Hybrid AC/DC Medium Voltage Distribution Networks

Year: 2026

Type: conference-paper

Abstract: The growth of MVDC technology opens the option of shifting from medium voltage AC (MVAC) distribution networks to hybrid AC/DC MV distribution networks. The earthing system of hybrid networks has a significant role in their operation and protection. This paper focuses on earthing systems for hybrid AC/DC MV distribution networks based on MMC technology with a symmetrical monopole configuration. Guidance for selecting the earthing system for hybrid AC/DC MV distribution networks is provided through the analysis and comparison of earthing systems using transient simulations. The theoretical feasibility of a transformerless AC/DC MV hybrid network is also investigated in this paper.
