Grid services: Frequency control
Timeline of the mains frequency:
- Charging
- Dis-charging
16
Grid Services: Frequency Control - Primärregelleistung
Frequency Control:
• Required approx. 550 – 600 MW in Germany, 3.000 MW in Europe
• Weekly auction for the following week
• Till today just a few provider, manly power plant owners
• Min. volume: 1 MW, prequalification required

BESS ON- / OFF-grid - Applications
ON – grid: Current source (similar to Solar Inverter), unit injects current !
OFF – grid: Only in parallel to GenSets ?
The unit isn’t building the grid!
Yes: ON – grid:
Current source !
No:
Voltage source !
Grid building
mode!
Unbalanced loads
Different grid trafo (“Z-type”)
Protection:
- Overload
- Inrush currents
- Fuse clearance
- Selectivity of protection
SC.EMS !
