CARP Simplified Model for Distribution
Note from Jennifer Curran, MISO:
The
attached is a highly simplified model of injection / withdrawal.
1)
The results should not be taken as the exact answer for how an
overlay would be shared across zones. A number of assumptions were
made for this quick model that would be improved as we move forward
with additional analytics. The model is primarily intended to help
further clarify the mechanics of the injection /withdrawal.
2)
This is very loosely based on the RGOS 765 kv/345 kv combination
overlay that OMS CARP decided to use in the upcoming analysis. It
does not reflect in any way other transmission including, but not
limited, existing transmission, planned reliability transmission,
planned generator interconnection costs, etc.
3)
Because it is loosely based on the RGOS overlay, and there is no
indicative overlay transmission currently mapped in Montana,
Kentucky or Pennsylvania, those states will show zero cost in the
local bucket (recall that the local layer reflects the location of
the transmission
4)
The simplified model allows you to change whether any layer is
access or usage, as well as how much revenue requirement is assigned
to each of the layers. Other assumptions (such as how much
transmission is physically located in a zone) are fixed.
