Does the ENET 39 network come with standard solar irradiance data, or does it assume a capacity factor of 1 if no irradiance data is fed?

If irradiance data needs to be fed, is there a tutorial for that?

Hi @keac139,

Yes, the ENET39 comes with solar irradiance data for the 6 PV objects in the network by default. Each PV object has its own associated profile and a PSET Event linking the profile with the object.

If you wish to add additional PV objects you can:

  • reuse those same profiles with your new PV objects by creating PSET Events for your new PV objects and pointing to the same profile of a nearby PV object that already exists in the ENET39
  • import your own profiles (check out this discussion for more details on that)
  • use the built-in weather data connections in SAInt to generate profiles from historical data directly in the SAInt GUI (follow these how-to guides 1, 2, and 3 if you are interested in that)

I hope this helps!

Thank you @will Can you provide more information on how to reuse the existing plant’s profiles as PSET events?

Hello @keac139,

It’s good to keep in mind that profiles, whether for the solar plants or in general, are only present in the scenario. The network does not contain profiles. The ENET39 has 6 PV objects, and each of the scenarios in the MRD are configured with 6 unique profiles for each of those PV objects. However, there is nothing constraining you from using the same profile for a variety of other objects/properties.

Let’s imagine you’re using the PCM_PEAK_DEMAND_WEEK.esce, which has 6 PV profiles that attach to the 6 PV objects in the network. You’ve added a new PV object, PV.keac139, and you’d like it to use the profile PRF.PV_QUINEBAUG_PSET_PU. This profile is normalized, which means it is intended to be scaled by the PMAXDEF of the PV object, which in this case represents the capacity of the PV plant. So, be sure to see PV.keac139.PMAXDEF to the value you’d prefer.

With the scenario open, you will add a PSET event to this PV.keac139 object. Now, check the property editor of this PSET event where you can find ProfileName, which has a drop down to select any profile present in the scenario. Select PRF.PV_QUINEBAUG_PSET_PU. Finally, in the Value field for the event, supply PV.keac139.PMAXDEF. There are some time shifting elements to be careful with, and I encourage you to read the documentation about them, but this general approach will get you started.

Happy Modeling,
