This energy system model was used in the publication Flexibility options for enhanced use of electricity from renewable energy sources - A qualitative study on two regions in Germany that was presented at SDEWES 2020 . Below you find links to the results.

Summary and conclusions

The expansion of renewables leads to new economic and social challenges, for example grid congestions and land-use conflicts. This study investigates supply-oriented flexibility options for the electricity system (i.e. battery storages, power-to-heat, demand-side management) and their potential to enhance the integration of renewable energy sources into the energy system. The techno-economic potential is analyzed by using a dispatch optimization energy system model (see Energy system model ), applied to 39 distinct scenarios (see Scenarios ) that cover various combinations of renewable energy penetration, degree of autarkic supply, flexibility options, and restrictions on land-use.

Most importantly, we find

  • Enough space is available for required wind and PV installations to serve at least regional demand with RES

  • High potential for energy exports, depending on land use restrictions

  • Land use restrictions need to be revised for accessing large-scale RES potential

  • Climate neutral scenarios can technically work, even with a high degree of autarky by using flexibility options

  • Rather small amount of regional demand is served from national grid
