Abstract

This paper presents a Modelica library for electrical grid systems for low-voltage distribution grids and in-building grids. The library is based on previous work; in which a library was presented to simulate fully balanced three-phase low-voltage distribution grids. This library is extended to simulate three-phase unbalanced low-voltage distribution grids as part of the IDEAS library. 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. Control strategies for appliances can use grid variables; such as voltages and power exchanges.
