| Popis: | 31st European Photovoltaic Solar Energy Conference and Exhibition; 3107-3111 2006 the International Building Exhibition (IBA) started in Hamburg under the device “Cities new building”. One Part of the IBA Program was “Cities in climate change”. In these part the question of combining climate protection with urban growth should be answered. For this, a working group started to develop the “Energy atlas for Hamburg-Wilhelmsburg”. There, different scenarios of the future energy demand were developed, potentials for energy saving and energy efficiency were identified and concrete step for the realization of these scenarios were shown. 2012 the “Island-Power study Hamburg-Wilhelmsburg” was realized. These study replied the question of the dynamic between energy demand and supply in 2050 under consideration of the realization of the Excellence- Scenario from the Energy-Atlas, including storage technologies and load management. The simulated scenarios showed that the 100%-Renewable-Energy-supply that was calculated as a yearly balance in the “Energy-Atlas” is not accessible in form of a local autarky. The high fluctuation of the electricity supply in the dynamic scenario tends to high surpluses and deficits. System operators are confronted with a complete new situation; higher load and the changing of the load flow direction are crucial. 2014, the Island-Grid-Study followed, to show whether todays lowvoltage and middle voltage grids are able to transport the electricity under the aspect of load flow changes and high power production from the PV side installed in the city quartiers of the future. |
