Modelling the impact of the energy transition on gas distribution networks in Germany

The energy transition is leading to profound changes in all parts of the energy system, but the reduction of fossil fuels in the heating sector is a major challenge for the energy sector. The changing heat-generating structure also affects its supply infrastructures. The impact on the existing elect...
