Prescribing Ramp up and Ramp down rates for thermal power generation capacities
#4
Dear Dr. Antti,
Greetings of the day.

I would like to have some more details on prescribing ramp-up rates to a process. Although I tried to find details on ACT_UPS in TIMES documentation but could not find something concrete.

As per AnswerTIMES, ACT_UPS is the “max change in load level in proportion to the capacity, per hour”. You shared that its unit is fraction of nominal on-line capacity per hour.

For instance, if there is a plant having capacity 100 MW and in hour 01 it is operating at 60 MW with a ramp up and ramp down rate of 10%. So now if the model requires to ramp up the coal generation than what is the maximum capacity it can increase in Hour 02 ?

So, if 10% ramp up rate is prescribed on the online capacity 60 Mw than the capacity that can be achieved will be 66 MW in Hour 02?

Please clarify whether my understanding of the concept is right or not.
One more thing, is it necessary to prescribe unit size while defining ramp up rate for a process?

Warm Regards
Vinay Saini
