Open-Source Active Distribution Grid Model with a Large Share of RES- Features, and Studies

Future distribution grids are likely to shift away from a passive grid consuming power to an active grid with a high share of weather-dependent renewable generation. Distribution grid operations are greatly interlinked between different voltage levels and depend upon the fluctuating load demand. Thus it is imperative to study and analyze multivoltage level distribution grids to understand the challenges and opportunities in a distribution grid with a high share of weatherdependent generation.

In this research, an open-source multivoltage level distribution grid model, named the DTU 7k-Bus Active Distribution Grid Model, is presented. The distribution grid model spans across three voltage levels and is modeled on geographical data for network topologies. The generation and load time-series provided with the model are simulated from weather data and derived from measurement data respectively.

This work addresses key features of the model and highlights challenges due to the high share of renewables.
