Abstract
This paper presents a dataset describing two semi-urban and two rural Norwegian residential low voltage grids. The grids have a radial structure and have a nominal voltage of 230 V. Each grid comes with a corresponding load time series for each consumer with one hour resolution, spanning one year. In order for the dataset to be customizable, the load time series do not contain extra elements such as PV production profiles or electric vehicle charging. On its own, the dataset enables more precise power flow analysis of low voltage distribution grids, but it can also be coupled with medium voltage distribution grids for studies on integrated medium-low voltage distribution systems. © 2025 The Author(s)
