EPRIs OpenDER model aims to accurately represent steady-state and dynamic behaviors of inverter-based distributed energy resources (DERs). The model follows interconnection standards or grid-codes and is informed by the observed behaviors of commercial products. Currently, model version 2.0 includes photovoltaic (PV) and battery energy storage system (BESS) DER behaviors according to the capabilities and functionalities required by the IEEE standard 1547-2018. This first-of-its-kind model can be used to run snapshot, Quasi-Static Time Series (QSTS), and a variety of dynamic analyses to study the impacts of DERs on distribution operations and planning.

OpenDER is under active development. Use the following resources to get involved.
Python >= 3.7
Dependencies of the package are auto-installed by pip command below.
pip install opender
Example script: main.py
This example generate DER output power in a dynamic simulation to demonstrate DER trip and enter service behavior. The grid voltage is set to be alternating between 1 and 1.11 per unit every ~10 minutes. DER should be observed to enter service and trip periodically.
