To access the Storage library, select the Library icon 
found on the upper right hand corner of the main window. Choose the Storage component tab as highlighted in the image below view your options.
You may select the View and Edit Storage Library to view or edit one of the default batteries or choose to create a new component using one of the templates below.
•Idealized Storage Model: This models a simple storage assuming a flat capacity curve. The Generic 1kWh Li-Ion battery is an example of this model.
•Kinetic Storage Model: This model includes the available and bound storage tanks for reduction in available capacity at higher discharge rates. The Generic 1kWh Lead Acid battery is an example of this model.
•Advanced Kinetic Storage Model: This model includes rate dependent losses, temperature dependence on capacity, cycle lifetime estimation using Rainflow Counting, and temperature effects on calendar life. The Generic 1kWh Lead Acid [ASM] and Generic 1kWh Li-Ion [ASM] batteries are examples of this model.
View and Edit Storage Library
You may view the Storage Component details by clicking on one of the models. To edit an existing model, select the Copy button located on the upper right. You may customize all the parameters of the Component in the Library. Each storage model can have inputs in common with other models and unique inputs that are characteristic of the system. The following list contains inputs that are common across the storage models.
•General Parameters: Common to all storage models
•Storage inputs including the capacity curve: Unique to the Kinetic and Modified Kinetic storage model
•Lifetime Inputs: Common to all storage models except flywheel. Modified Kinetic model has a unique set of lifetime inputs.
•Temperature-sensitive information of the Storage System (Temperature versus Capacity and Temperature versus Lifetime): Unique to Modified Kinetic storage model
•Default Cost Information: Common to all storage models, although some of the inputs in this tab vary for different models
Variable |
Description |
Name |
A unique name used to identify this type of storage. |
Abbreviation |
A short, distinctive name to identify this storage on the schematic and in the results. There is no specific limit on the abbreviation length, but long abbreviations do not fit well on the schematic or results. |
Manufacturer |
An optional field used to specify the manufacturer of the storage. |
Website |
An optional field to provide text for a web link for the storage. |
Url |
The actual web address of the link defined in the Website input. |
Notes |
An optional field used to specify additional specifications, manufacturer contact information, or anything noteworthy. |
Storage type |
Select a type from the drop-down menu to change the category of storage component as it is organized in the pop-up menus on the Storage Set Up page under Design. This input has no effect on the technical modeling of the storage item. |
The Batteries (or Quantities) area under the Defaults tab includes the initial capital cost and replacement cost per storage, as well as annual operation and maintenance (O&M) costs per storage unit. When specifying the capital and replacement costs, be sure to account for all costs associated with the storage, including installation.
Note: The capital cost is the initial purchase price, the replacement cost is the cost of replacing the storage unit at the end of its lifetime, and the O&M cost is the annual cost of operating and maintaining the storage.
For more details on this input, see the Storage Component section of the help.
