Modelling of a Storage Process
#2
The capacity of your storage represents the maximum amount of energy that can be stored by the device.

As far as I can see, your conversion of the storage flows from PJ to MWh are quite correct.  Therefore, in 2035 the daily input into your storage is in total 4839.8 MWh.  According to your input data, only 60% of the storage capacity is available for operational use, and therefore the capacity needed for the daily charging of 4839.8 MWh is 4839.8 / 0.6 = 8066 MWh.  This amount of energy is equal to 0.029 PJ,  which we can convert to the capacity unit by dividing it by PRC_CAPACT=31.536.  Thus, in terms of your capacity units, the capacity required for the daily charging is 0.029 / 31.536 = 0.00092 GW = 0.92 MW.

As you can see, the calculation gives a value just slightly larger than what you show in your table, 0.90 MW.  However, I think that is probably due to a rounding error, because your capacity unit appears to be GW, and ANSWER-TIMES reports the results with only 4 decimal places, and so the reported value would be 0.0009 GW.

For 2040, similar calculation gives the capacity required for the daily charging as 0.0359 / 31.536 = 0.001138 GW ≈ 1.1 MW.

So, in response to your request:

AL>  I see nothing wrong with your modelling of the storage process, other than your unnecessarily big capacity unit (GW). I don't know the reasons for the variation in the discharging flows (Var_Flo_Out), but I think such a variation is quite natural for a storage operation.
