Gas Storage Withdrawal Volume

Units:	1000·~ (Metric), ~ (U.S. Imperial)
Mode:	Input Only
Multi-band:	True
Default Value:	0
Validation Rule:	Any Value
Key Property:	No
Description:	Storage volume for which withdrawal is allowed
Detail:

Gas Storage Withdrawal Volume is Storage volume for which withdrawal is allowed in that given band. Further withdrawals from the storage causing the volume to drop below this value takes the simulation into the next band. The value Withdrawal Volume corresponds with the Withdrawal Rate Scalar value for each band.

When Use Additive Ratchet is Yes, the input is incremental, starting from the last band to the first. Consider the following gas storage withdrawal ratchet:

Property	Value	Units	Band
Max Volume	1000	TJ	1
Initial Volume	1000	TJ	1
Withdrawal Ratchet	100	TJ	1
Withdrawal Volume	400	TJ	1
Withdrawal Rate Scalar	50	%	1
Withdrawal Volume	300	TJ	2
Withdrawal Rate Scalar	30	%	2
Withdrawal Volume	300	TJ	3
Withdrawal Rate Scalar	20	%	3

This defines a 1000 TJ Gas Storage with three withdrawal bands. Band 1 has a volume of 400 TJ and can be withdrawn from at a rate of (0.5 + 0.3 + 0.2) * 100 TJ per time period. Band 2 has a volume of 300 TJ and can be withdrawn from at a rate of (0.3 + 0.2) * 100 TJ per time period after band 1 has been depleted. Lastly, band 3 has a volume of 300 TJ and can be withdrawn from at a rate of 0.2 * 100 TJ per time period, after bands 1 and 2 have been depleted.
