Modelling Pumped Hydro Energy Storage - Ansh_02 - 19-01-2024

Hello Dr. Antti Happy New Year. I hope you are doing well. I am developing a standalone power model for India and want to add pumped hydro energy storage technology. I have the following data to define my technology. Overall Plant Efficiency           74% full load operation in generating mode  6 hrs/day CYCLE EFFICIENCY              76% AUXILIARY CONSUMPTION   1% PLANNED OUTAGE          10 days Total Potential                97 GW Capacity till 2020            3 GW Technical lifetime            40 years Construction time           8 years Charging efficiency         80% Ramp Up Rate             50% of Full Load/Minute Ramp Down Rate            50% of Full Load/Minute Capital Cost        935 USD/PJ Fixed O&M         23 USD/PJ/yr So, I have added a process where I have defined the following parameters. Parameter         Item 5/6             2020      2030 CAP_BND           FX                         2.6        CAP_BND           UP                                        20 NCAP_AFC          DAYNITE             0.33         0.33 NCAP_BND         UP                                        20 NCAP_COST                                 935           935 NCAP_FOM                                   23              23 NCAP_ILED                                   -8              -8 NCAP_TLIFE                                  40             40 STG_CHRG                                   0.95        0.95 STG_EFF                                       0.9          0.9 STG_LOSS                                    0.03        0.03 The model horizon is extended till 2070, and I have the following queries:
  1.  I wanted to add cycle efficiency with STG_MAXCYC, but I couldn't find that in my parameter list (my TIMES version 6.9.24)
  2. How could I model ramp up and down rate for this process, and what are the parameters?
  3. How could I add 'full load operation in the generating mode' and overall plant efficiency? 
  4. With the above parameters, I was able to run the model, and in the results, I only got capacity numbers for this process but NO Activity nor VAR FLO OUT. Why is the process not generating even if it has capacity?
