  1. Operating the Future European Power System with 100% Renewables – A System Study based on the Energy [R]evolution Scenario Dr.-Ing. Eckehard Tröster Energynautics GmbH, Germany 17th March 2011

  2. Agenda 1. Objectives 2. Power System Analysis Method 3. Results on DSM, Storage, andGrid Upgrade 4. Conclusions

  3. Agenda 1. Objectives 2. Power System Analysis Method 3. Results on DSM, Storage, andGrid Upgrade 4. Conclusions

  4. Greenpeace Energy [R]evolution Scenario • RES share (TWh) 67% in 2030 and 97% in 2050 • Installed capacity in Europe:  Wind power plays a major role in the future power system! 376 GW 497 GW

  5. ObjectivesofGrid Study • Determine the grid infrastructure required for Energy [R]evolution Scenario • Explore different measures for optimal integration of Renewable Energy Sources into the European electricity grid

  6. Agenda 1. Objectives 2. Power System Analysis Method 3. Results on DSM, Storage, andGrid Upgrade 4. Conclusions

  7. European Electricity Grid Model • DC-model of European network in DIgSILENTPowerFactory. • Lines are aggregated to form a 224- node model connecting load centres. • Due to its simplicity it is well suited for a general European grid upgrade study.

  8. Methodology – Grid Planning

  9. Extreme Winter Event Low wind production!

  10. Extreme Winter Event Low solar production!

  11. Extreme Winter Event High demand!

  12. Agenda 1. Objectives 2. Power System Analysis Method 3. Results on DSM, Storage, andGrid Upgrade 4. Conclusions

  13. Curtailed energy for Base Scenario 2030 with DSM 5%, 10%, and 20%. Impact of DSM is limited!

  14. Curtailed energy for Base Scenario 2030 with storage Impact of Storage is limited!

  15. Grid upgrade optimisation process By further upgrading the grid, the amount of curtailed energy can be strongly reduced 12% 3%

  16. DSM/Storage vs. Grid Upgrade Contributes to RES integration and improve SoS RES Integration RES curtailment Security of Supply Grid upgrade Storage and DSM Back-up Capacity Contributes to RES integration when grid is restricted and RES-share is high, does not improve SoS... ...requiring backup generation to cover SoS

  17. High-voltage network of Europe in 2030 • Critical areas for grid upgrade in future: • South to Central Europe • North Sea Offshore Source: Reproduced with permission of ENTSO-E by energynautics.

  18. High-voltage network of Europe with the proposed HVDC Supergrid in 2030 The Supergrid starts to develop: It connects South and Central Europe! Source: Reproduced with permission of ENTSO-E by energynautics.

  19. High-voltage network of Europe with the proposed HVDC Supergrid in 2050 The Supergrid is formed: It connects North Africa with the Centre of Europe! Source: Reproduced with permission of ENTSO-E by energynautics.

  20. Summary of grid upgrades

  21. Overview of key results of all scenarios

  22. Agenda 1. Objectives 2. Power System Analysis Method 3. Results on DSM, Storage, and Grid Upgrade 4. Conclusions

  23. Conclusions • RES should be prioritized on a European level in order to reduce amount of curtailed energy • Impact of demand side management and storage is limited in 2030 but more significant in 2050 when transmission is constrained and RES-share is high • Further grid upgrades have highest impact on curtailment • Dispatchable generation has to be flexible to gain a high share of renewables in the system • Utilization of conventional power plants will be much lower than today (extended use of inflexible conventional power displaces renewables)
