Hosting capacity of meshed distribution grids with and without smart solutions

Alternative solutions, instead of building new transmission lines, are needed to enable the fast electrification of sectors such as industry, transportation, and heating. This includes smart-grid technology allowing for an increase in hosting capacity without the need for building new transmission lines. The increase in hosting capacity beyond the firm hosting capacity is, with many of the schemes, related to the ability of the installation to tolerate curtailment. The paper gives an overview of different smart-grid schemes and how they potentially increase the hosting capacity. The connection of a large electrolyser installation for hydrogen production is used as an illustrative example introducing some of the issues.
