Dear Dr. Antti,
Greetings of the day.
Thank you for sharing such great insights every time.
I tried the ACT_UPS the way mentioned for a coal based power plant in hourly model.
I prescribed the following to the plant:
a) ACT_EFF as 0.30
b) ACT_UPS (LO) as 0.10 and ACT_UPS (UP) as 0.10
c) NCAP_AF (LO) as 0.55
d) NCAP_AF (UP) as 0.85
e) NCAP_COST, NCAP_FOM, NCAP_TLIFE, etc
Although the plants follow the limits of 55% and 85% for capacity operation however the ramping limits are not followed by the plants during some hours of a year. The ramping rate has been in the order of 20 to 30% for some hours in a year. Please suggest what could be the reason.
Further, I read the document shared by you and I really find that document interesting. I am particularly interested in using the partial load efficiencies for my coal process. However, I am confused about the parameters to be used for the same as in my AnswerTIMES I am not able to see these parameters (I am using Answer Version 6.9.7). Please help me with what parameters I need to use and from where to activate those parameters in my AnswerTIMES.
