Battery augmentation strategy

Hi Luana,

For now, it is not possible to change the system design over time, so no, it is not possible to add battery capacity when the battery is replaced.

Can you describe more about the scenario you would like to model?

Best regards,
Paul.

Hi Luana,

Thank you for the explanation. The authors in that paper use the term "augmentation" to mean that rather than replacing the entire battery bank when its capacity degrades below a certain storage capacity, the system owner would add batteries to the bank.

To model that kind scenario in SAM 2020.2.29, choose the Replace at specified schedule option under "Battery Replacements" on the Battery Storage page. For Battery bank replacement schedule, click Edit array and enter a 1 in the row for each year you would like the battery to be replaced (Row 1 is for Year 1). Then, for Battery bank replacement percent, enter the percentage of the battery's original installed capacity required to achieve the desired "augmented" capacity in each of those years.

Be sure to also define the battery replacement cost on the System Costs page under "Operation and Maintenance Costs."

Best regards,
Paul.

Hi Jawwad Aga,

Please attach a sample Python script (and any supporting files) that demonstrates the results you are seeing if you would like me to help troubleshoot.

Best regards,
Paul.
