Renewable energies integration in a DiNeMo model based on a German urban grid

With the emerging rise of electricity production coming from distributed generation (DG), the need of having reliable distribution grid models to study DG integration is emerging. Distribution Network Models (DiNeMo) platform aims at covering this gap by reproducing the representative distribution grid of a given area of interest. The models are based on data relative to the area and on indicators built from the data provided by 99 European Distribution System Operators (DSOs) supplying more than 100, 000 consumers. Among the outputs that DiNeMo provides, the key files are those which allow to run power flow simulations. In this paper, we report the results of AC power flow analyses relative to an urban network of the city of Hannover. Our focus here is the study of voltage fluctuations and line losses under different levels of household photovoltaic installation. Starting with a current state of demand without any household having installed photovoltaic (PV) panels, we move to the analysis of higher penetration levels. After that, we run additional simulations to assess the impact that meshed medium voltage (MV) network configurations can have on the capacity hosting of the grid in exam.
