This paper presents a Modelica library for electrical grid systems for low-voltage distribution grids and inbuilding grids.The library is based on previous work, in which a library was presented to simulate fully balanced three-phase low-voltage distribution grids [1].This library is extended to simulate three-phase unbalanced low-voltage distribution grids as part of the IDEAS library [2].The library also allows to simulate in-building AC and DC grids.The AC grids can be single-phase or three-phase (un)balanced grids.Electrical grids may connect many different energy systems (loads and generation units), different grids and/or buildings within districts.The library allows to assess the grid impact of these systems on different grid types.Control or optimization strategies can use grid variables, such as voltages and power exchanges.
