Battery Dispatch Scenarios

Hello and good day,

I am trying to model a commercial building with a grid connected PV and battery setup to simulate the following scenarios;

• Battery charges through PV when there is excess PV
• Battery charges through Grid when electricity price is below a certain limit
• Battery supplies to the system when PV is lower than the load and electricity price is higher than a certain limit
• Battery supplies to the grid when PV can sustain the load and/or the electricity price is higher than a certain limit 

I am wondering if this would be possible to simulate through SAM? If so which of the performance/financial models should be chosen?
Thanks in advance for your help!

Hi Deniz,

If the electricity price can be defined using the energy charge table on the Electricity Rates page (with no demand charges), then you should be able to model this scenario with the PV-Battery / Commercial configuration.

The attached example shows how to set that up for energy rates with four time-of-use periods.

If the electricity price varies by time step, or the rate structure involves demand charges, you could use the Price Signal Forecast option and write an LK script to calculate the time series prices.

Best regards,
Paul.
