Abstract
Future MVDC grids will be used to reinforce the grid infrastructure enhancing transmission capabilities, minimizing losses, and providing capability to compensate reactive power as well as to control load flows. This paper addresses the protection of MVDC grids, which is one of the main challenges to be overcome, before taking advantage of all the inherent benefits that this technology will bring. The main objective of this paper is to validate a non-unit voltage derivative fault detection algorithm in a MVDC grid with green hydrogen production. The performance is analyzed with different fault cases and fault locations. As a main conclusion, the distance is the most relevant factor, which affects detection and tripping times.
