| Description: | Number of cycles completed |
Flow Storage Age is the number of cycles completed in the given timeframe.
A complete charge and discharge, between the specified Min SoC and Max SoC values, is considered to be a full cycle with the Age based on 'shallow discharging', where the storage can partially draw down and then refill.
Age = (Withdrawal / Withdrawal Efficiency + Injection × Injection Efficiency ) × time / 2 × ( Max Inventory - Min Inventory )
The summary value of this property is simply the sum of the interval values.
