Dear Vinay
I just tested with a processs like you described, in an hourly test model. Just like you, I specified:
ACT_UPS (LO) = 0.10
ACT_UPS (UP) = 0.10
NCAP_AF (LO) = 0.55
NCAP_AF (UP) = 0.85
I fixed the capacity to 100 MW. In the results, the load levels of the process were the following in a sample day:
As you can see, all the ramp rates were exactly the maximum prescribed, 10% of the capacity per hour.
I also tested by trying to force the ramp rate a bit higher in a few timeslices, and got an infeasible solution, as expected.
Consequently, I cannot reproduce your findings on the basis of your description.
So, please provide more information, or a test model reproducing the unexpected behaviour.
