Important Notes
- All Eleven Symbols Required: Even if some symbols are not used for overriding, empty symbols must still be included in the
override.gdx
file for compatibility.
- Example File: For reference, you can check the
excelOverrides.gdx
file in the directory ..\vSPD-master\Override\
in vSPDv3.0.4
. (https://www.emi.ea.govt.nz/Content/Tools/vSPD/vSPDv3.0.4.zip)
- Understanding Dimensions: For the
demandOverrides(dim1, dim2, dim3)
symbol:
- dim1: Trading period (e.g.,
TP1
.. TP50
) or specific datetime (e.g., 01-APR-2020 07:30
).
- dim2: Node (e.g.,
ALB0111
) or island (NI
or SI
).
- dim3: Can be
scale
, increment
, or value
(in your case, use value
).
For additional details on the dimensions of each symbol, you can refer to the vSPDoverrides.gms
file.
Hope this helps clarify the structure and requirements!
