Reserve Market was created by Douglas Lindén

Hi!

Me and my friend are doing out master thesis looking at peak shaving for an industry in Sweden. We investigating a BESS for the peak shave but we also want to use the battery in a reserve market in Sweden to get extra revenue streams and hopefully make the investment more profitable. But the problem is that we don't know how to include the reserve market in our SAM model. Can you somehow write code and then let SAM include it in the model? We have the data for when this market is available and our battery has to deliver electricity to the grid.

Maybe the answer is easier then we think and we are grateful for all guidance!

Hi Douglas,

By "peak shaving" do you mean that the battery will be used for a behind-the-meter application to reduce the peak electric consumption of a building or facility? Or, is it for a front-of-meter application to help reduce the peak load on the grid?

How will you model the reserve market? Would you represent it as an array of time-series prices?

I think SAM's PV-battery model should be able to model your scenario. You might look at a PV-battery / Commercial configuration to for a behind-the-meter application, or the PV-battery / Single Owner configuration for a front-of-meter application.

You posted your question to the SDK forum, which suggests that you plan to build your own model that interacts with SAM through the API. You may be able to do your analysis in SAM's user interface without using the API. In any case, I would recommend starting with the SAM user interface to understand its capabilities before trying to use the SDK tools build a model.

Best regards,
Paul.

Hi Paul and thank you for your reply!

So the battery will be used for behind-the-meter applications in 99% of the time. The model is going to peak shave a load coming from an industry but also participate in a reserve market. This reserve market is what we wanted to build a script for since we couldn't fins it in the interface. This only happens a few times of the year, so what we wanted is something that could tell the battery that it needs to deliver a specific power to the grid for a certain duration. We could solve this by running the simulation with the battery controller set to "Automated grid power target", with this results we can size the storage. Then extract the new electric load, then calculate how the battery is going to deliver energy for each hour and here also include the reserve market. Then run a second simulation but with the battery in "Manual dispatch" in the battery controller with our manipulated battery dispatch.

This is why we wanted a script that can do all this in one simulation and so we don't have to do this for every industry, we might have 10 of them.

Best regards,
Douglas
