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:
- 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)
- How could I model ramp up and down rate for this process, and what are the parameters?
- How could I add 'full load operation in the generating mode' and overall plant efficiency?
- 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?
