Hello everyone,
I am trying to assign ramping-rate attribute for each timeslice and ran into some trouble.
My timeslices are defined like the attached image ("Fig1")
I have assigned ramping rate attribute ACT_UPS for each time slice like the attached image ("Fig2"),
so that, for example, for technology “ELC11PP-ANS1E”, the ramping rate (ramp-up and ramp-down) for timeslice SKN, SKD, SKP be 0.5, 0.3, 0.7 respectively.
From what I have understood from the formulation described in “Dispatching and unit commitment features in TIMES“ document,
ACT_UPS (UP) defined for timeslice s describes a ramp-up rate between timeslice s-1 and s.
Then is it that, for my model, if s=SKN then s-1=SKP, and if s=SKD then s-1=SKN?
If not, how can I set the order of each timeslice? (Please be generous and explain how it works in case I’ve got it wrong)
Also, in order to use ACT_UPS attribute, is it necessary to declare ACT_MINLD?
If that is not the case, what is a default value of ACT_MINLD?
I observed some significant load changes even though I have assigned ACT_UPS=0 across all time slices while doing some test-runs to see if I was on the right track.
Reasoning from the formulation, it looks like ACT_MINLD has some value though I have not declared it.
Please share your thoughts with me, and please point out things that I have misunderstood.
Thank you so much.
