Storage - Depth of discharge Dianaprz7 Junior Member Posts: 31 Threads: 10 Joined: Apr 2019 25-04-2019, 07:54 PM Hi, How can I model the "Depth of discharge" or "minimum storage charge" of a storage process in VEDA-TIMES? is there a specific attribute for this characteristic?

Absolute or proportional minimum?  For charge or discharge? If proportional, proportional to what? Absolute bounds for storage discharge can be defined by STGOUT_BND. A minimum discharge flow proportional to the storage level can be easily defined by FLO_SHAR (if it is a timeslice storage). Minimum discharge flow proportional to capacity would be also possible, but would require defining an auxiliary storage flow, and then a UC constraint referring to the aux flow and the capacity. Absolute bounds for storage charge can be defined by STGIN_BND. A minimum charge flow proportional to the storage level or capacity would be possible by defining an auxiliary storage flow, and then a UC. EDIT: Or do you mean minimum level for the state of charge?

Per instance, you can discharge 100% of a flow battery, on the other hand, CAES technology can only be discharge up to ~40% of its storage capacity.
