Abstract

Direct Current (DC) microgrids are gaining an international interest to improve the flexibility and the reliability of future distribution systems. DC microgrids are more suitable and efficient infrastructure for connecting and controlling distributed energy resources. However, they do present new challenges under different fault conditions. To design appropriate protection solutions to handle such challenges and ensure DC microgrid secure operation under different operation modes (grid-connected and islanded), there is a need to fully understand their fault behaviour under each DC microgrid mode. Therefore, this paper investigates in detail the fault behaviours associated with DC microgrids with local distributed energy resources under different fault conditions (e.g. DC pole to ground and pole to pole faults). A DC microgrid modelled in PSCAD/EMTDC with the appropriate layout, multiple earthing and control structures is used as a test network in the simulation fault studies.
