The protection of Multi Terminal high voltage Direct Current grids (MTDC) is one of the key issues to address to ensure the recourse to this technology for the transmission of power over large distances. This paper presents a method to compare protection strategies that can or could be used for such grids. This method is based on the use of dedicated key performance indicators (KPI) that are defined to evaluate the various protection strategies on the DC side. The method is described and applied on benchmark grid to compare three envisioned protection strategies.
