STEAG PROJECT

Germany: Steag project

The challenge

Primary frequency regulation (PFR) to the

grid to ensure stability

Scope of supply:

• EPC for 6 BESS for 15 MW/ 23MWh

• Net Voltage: 10 KV

• Total Peak Power: 90 MW

• Total Capacity: 138 MWh

Technology

•Optimized configuration: 1.5 MW/2.3 MWh

in 40’ container

•Li Ion Batteries

8/1 8/16

PFR – a simple concept

Each week the German national grid issues a tender for PFR services with 1 MW min size.

With 52 bids/year the service provider must be fast and competitive….that’s why STEAG

chose BESS and NIDEC

9/1 9/16

Meeting the stringent German Grid Codes

Minimizing losses to maximize profit

Meeting Health & Safety regulations

Deliver the entire project – 6 sites in less than 12 months

Automatic and complete activation within 30 sec in case of frequency deviations

Proportional regulation with droop (Statik) as proportional gain

Typical value 0,4% with -Pmax @ 200mHz / Pmax @ -200mHz

Frequency band to be covered 49,8 Hz….50,2 Hz

Deadband 50 Hz ± 10 mHz (49,99 Hz …. 50,01 Hz)

Time period to be covered per single fault at least 15 min

Continuous full call of primary control in prequalified technical units with capacity

limitation for at least 30 minutes

The primary control must be provided throughout the entire offer period (one

week)

Project Challenges

The German Grid Code requirements

11/1 11/16

Minimizing losses from auxiliaries

Our challenge

a) Heat mitigation Vs Guaranteed PeGu

b) Cooling systems cons

• Further heat generation

• Energy consumption

The solutions

1. External cooling device(chillers) w free

cooling mode by fans

2. External and sealed oil trafo(natural

cooling)

3. Trafo designed for no load losses

4. Smart State of Charge(SoC) and

State of Health (SoH) management

through algoritm to optimize

performance of the system

5. Simulation of SoC during eng phase

12/1 12/16

Health & Safety –

OUR CHALLENGE:

Being the first often means

having to find solutions to

problems that have never

been faced before.

On the market today there

are no containers that are

fully compliant with fire

safety regulations

Working with safety experts we

identified a reliable innovative solution

to solve the problem installing cement

fire containment walls between the

trafo and containers.
