[Equest-users] Using eQuest to Optimize CHP (co-gen) plant

[Bishop, Bill]

Russ,
 
In eQUEST, you have to manually enter the electrical generating capacity
of the plant. The Help Menu description is below:

CAPACITY
Accepts the capacity of the generator in kW. This is a mandatory entry,
as the program does not size electrical loads.
I would not create an eQUEST model for the sole purpose of sizing a
cogen plant if you have already done that with other programs and are
confident in your results.

Subject: [Equest-users] Using eQuest to Optimize CHP (co-gen) plant
 
Our firm has been told by a client that DOE-2 (and thus eQuest) can be
used to optimize the size of a combined heat-power (co-gen) plant within
the program (not by running several iterations and analyzing the results
to pick the optimal size). Is this correct?
We have already run iterations on the cogen plant size using two other
programs and completed manual analysis of the results to pick the plant
size, but would like to be able to answer our client's request.
 
Thank you,
 
Russ Arneson, PE
