Regionalization of four storylines for the decarbonization of the European power system including flexibilities

In this paper, we investigate the impacts of different types of electricity demand with potential flexibiliy, such as heat pumps, battery electric vehicles, and photovoltaic battery storage systems on the balance of electricity generation and demand on a European scale. In order to evaluate this impact of flexibilities, first, we perform a regionalization to allocate generation capacities and flexible demands to the distribution grid level. Secondly, a stochastic dynamic programming model is applied to consider the impact of household batteries on the electricity generation and demand on a single node and national level. In order to consider uncertain future developments of generation capacities and demand, we apply the methodology to four storylines that have been defined within the ENSURE project. The results show that a high share of decentralized photovoltaic battery systems can contribute in a beneficial way in situations with a high positive or negative residual load. However, the uncoordinated dispatch of these storage units can also lead to some avoidable curtailments of renewable energies.
