With the increasing share of variable renewable energy sources (VRE) in energy systems, the dependence of electricity production on weather conditions increases. In addition to dispatchable power plants, storage systems, demand-side management, the expansion of electricity grids and the import and export of electricity with foreign markets can provide the increased need for flexibility. European balancing depends on market-driven decisions and physical restrictions on the topology of the transmission grids and in particular on cross-border interconnectors.
The aim of the project is to assess the security of supply of electricity in Germany in extreme weather situations, taking into account the potential for intra-European balancing. In addition to the European expansion of the VRE, the potentials of cross-border trade between several European market zones and the cross-border net transfer capacities (NTCs) are included in the calculations. The NTCs depend on the given system conditions and the prevailing weather and are therefore dynamic. These interdependencies, especially in the case of extreme weather events, are explicitly integrated into the analysis of cross-border trade.
The functional scope of the REMix-EnDAT and AMIRIS models, developed at DLR, will be extended in this project. On the one hand, we calculate the effect of extreme weather events on the security of supply in electricity systems with high VRE shares; on the other hand, we take into consideration the power plant structures in the European countries, the transmission restrictions and the European electricity trading.
