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 !

BESS – main components:

Storage Converter: IEC: SC.250, SC.330, SC.500, SC.660 – ID – GER

UL: SC.300, SC.600 – ID – UL (complaince)

SC.LvS-1 / -2: Similar to PV.LvS-1 / -2

Trafo: 3 coils – On-Grid: as in PV; Off-Grid: t.b.d. similar to UPS

DiCa: Only for US market, due to UL requirements

BMS: i.e. Battery supplier

SC.LMU: Local Management Unit, based on PLC (Siemens S7)

SC.EMS: Energy Management Unit, based on PLC (Siemens S7)

25
