Antti, Thanks for a quick feedback.
we have defined both type of stg technologies, TSS and IPSS. I am not interested to have the latter, but without which I am getting infeasibility. I suspect, it was due to lower bound on pumped hydro, input to which is fed from the two storage technologies. But initial storage is not defined in the modelled (which I must do now). Thus I added the small capacity of IPSS and the model solves. But the IPSS keep on generating some output and activity, but no input. from yr feedback, now I guess, the IPSS tech simply assume an inital storage and keep on generate commodity outputs!
The fact is that, if I switched off the IPSS, even the TSS is not taking up. model chose dummy import to fulfil the pumped hydro ACT bound. I should have defined an initial storage (STG_CHRG ) for TSS! let me try now. Sorry, what is BoH?
Since it is a hourly model, I am keen to use the weekend solar PV outputs for pumping. but it not happening, even if I adjusted the cost to pick up this stg tech
