Protection assessment in electrical distribution grids based on state estimation

Solutions for blinding of protection in today's and future German LV grids with high inverter penetration – simulative and experimental analysis

“…The IIDGs are configured to follow the present and future VDE‐AR‐N 4105 guideline. Due to the fact that the CIGRE LV benchmark grid does not completely resemble typical German LV configurations, especially regarding line types and lengths, additional altered grid configurations are investigated [3]. On the basis of the results, alternative fault detection methods, as known from higher‐voltage levels, are analysed and benchmarked.…”
