Energy in Storage
The methods available in the Energy in Storage category are used to calculate the total energy that could be produced by the water stored in the reservoir.
* None
Chosen if the user does not want to calculate the Energy In Storage. No slots are specifically associated with this method. This method performs no calculations.
* EIS Table Lookup
The EIS TableLookup method obtains the amount of Energy In Storage from a table of Pool Elevation vs Energy In Storage values and the Pool Elevation.
Slots Specific to This Method
 Energy In Storage
Type: AggSeriesSlot
Units: ENERGY
Description: Energy In Storage in the Reservoir
Information:  
I/O: Output only
 Energy In Storage Table
Type: TableSlot
Units: LENGTH vs ENERGY
Description: Pool Elevation vs Energy In Storage In the Reservoir
Information:  
I/O: Required input
Method Details  
The calculations involved with this method are very simple. The Pool Elevation for the current timestep is used to determine the Energy In Storage using the Energy In Storage Table. Simple linear interpolation is used.
* EIS Table Lookup with Cons Pool
This method will be available only when the Conservation Pool or Conservation and Flood Pools method in the Operating Levels category is selected.
Slots Specific to This Method
 Energy In Storage

Description: The EIS at the Top of the Conservation Pool
Information:  
I/O: Output only
Method Details  
The method is executed at the end of each dispatch method.
The Pool Elevation for the timestep is looked up in Energy In Storage Table. Simple linear interpolation is used. The resulting Energy in Storage is then set on the slot.
Next, the Conservation Pool Full EIS is calculated as follows:
    
    
Note:  In the equation, the appropriate Operating Level Table will be used based on the timestep and the computation in the selected method in the Conditional Operating Levels category.
