23. Electric mobility enables efficient integration of RES
Network integration is decisive for business model:
“Vehicle to Grid” (V2G) requires “Grid for Vehicle” (G4V)
Use of “plug-in” capable vehicles as distributed mass storage systems for
providing system services
+ Error tolerant
+ Regionally controllable
+ Cost effective due to double use
+ Additional energy sales
Bottlenecks:
- Battery storage (techn.)
- Grid connection (economic)
- Poss. greater loads in the low voltage Just 660,000 vehicles would be able to provide
sector in the low tension grid more balancing power (for approx. 1h) than all of the
German pumped-storage hydroelectricity plants
combined.
