I have a battery system configured to operate in GFM to energize a network without a substation. Despite the battery being relatively small, the loads are still being energized.
For simplicity, I have modified the load to be a constant value. Here are the specifics:
Despite the small battery size, the L-N voltage shows that the loads can still be energized. I am looking for insights or explanations as to why this might be happening.
It is clear that you forgot to add the InvControl. If you look at the other examples on GFM, the device behaving as GFM has an InvControl associated, this helps limiting the current of the device following the DSS control process.
Give it a look again and add this controller to your implementation.
Best regards,

Hi, Dear Davis
Thank you for your comments. However, in this case, I think I've already included the necessary InvControl in the code. Please see the attached. Sorry for not uploading the dss file in the previous post.

Dear all,
I have a battery system configured to operate in GFM to energize a network without a substation. Despite the battery being relatively small, the loads are still being energized.
For simplicity, I have modified the load to be a constant value. Here are the specifics:
Load Shape:
New Loadshape.ConstDailyLoadShape npts=24 interval=1 mult=(1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0)
Loads Definition (loadsL1.dss): constant loads
...
New Load.Load_1020889571 Bus1=Load_1020889571 Phases=3 kw=3.0 kv=0.207 pf=0.95 daily=ConstDailyLoadShape
New Load.Load_1020889572 Bus1=Load_1020889572 Phases=3 kw=3.0 kv=0.207 pf=0.95 daily=ConstDailyLoadShape

Battery DER Configuration:

Despite the small battery size, the L-N voltage shows that the loads can still be energized. I am looking for insights or explanations as to why this might be happening.

Hello,

Would you mind to provide the load declaration file?
Best regards,
