Standalone Battery Peak Shaving Dispatch

Hi Jethro,

SAM's automatic peak shaving algorithm does not have these options. You could use the manual dispatch option to set up a dispatch schedule that approximates the dispatch strategy you describe.

Hi Paul,Thanks for the response. Following up to get some more clarification for my use case (figures attached). So if the peak shaving algorithm is not driven at all by demand charges, what exactly is it driven by in my use case when accounting for my 8760-hr load power profile? Is it driven by the automatic dispatch process in this paper ( www.nrel.gov/docs/fy18osti/68614.pdf ) or is there another process/other documentation?

Thanks for your time.

Hi Jethro,

The automated dispatch algorithm for stand-alone batteries does respond to the load data and rates for demand charges.

In the results, you should see the battery discharging to the load during times of peak demand in an attempt to reduce the demand charges.

It looks like the battery you are modeling has a very high maximum discharge capacity of 3 million kW.

Best regards,
Paul.
