SVP Additional Tools

This is collection of scripts and tests that are useful for debugging the System Validation Platform's interaction with different equipment. It provides examples of interacting with equipment of the same type, e.g., communicating with multiple DER devices. It also provides some simple examples of testing that are not included in the larger projects to create IEEE 1547-2018, UL 1741, and other working directories.

Multi-input inverter testing

The multi_mppt_analysis.py script was used to create a model and test protocol for overall DC-to-AC power conversion efficiency for multi-input inverters. Information on this work is at the following citations:

Stand-alone Scripts

These are helpful native python scripts that do not rely on the SVP GUI framework to run. They may be useful in early-stage debugging.

Installation

Install the SVP dependencies using this guide. It’s recommended to use Python 3.7.X because there were some issues reported for 3.9+.

To run an SVP test, you will need to do the following:

1. Copy the Lib directory from the svp_energy_lab into the Lib folder in svp_1547.1 (we decided to keep a single, separate copy of the drivers in svp_energy_lab to simplify management).
2. Run the ui.py code in the opensvp to generate the GUI.
3. Navigate to the Interoperability Test in tests in the left pane of the GUI, right click -> edit.
4. Run the test and verify it works.
