IEEE 34 Node Feeder XENDEE Test Cases

IEEE 34 Node Test Feeder is an existing feeder located in Arizona, with a nominal voltage of 24.9 kV. It is characterized by long and lightly loaded overhead transmission lines, two in-line regulators, one in-line transformer for a short 4.16 kV section, a total number of 24 unbalanced loads, and two shunt capacitors.

The guide provided in IEEE34Node.Zip is one of several designed to support skills development in distribution network modeling. It can be used during standard university curricula, a short industry course, self-guided lessons, peer learning, or other training opportunities. Files resulting from the guide can also be modified at the discretion of the user to pursue advanced topics of analysis. The IEEE Test Feeders are used as examples given their wide recognition and use. Resulting power flow analysis and short circuit analysis are presented in separate documents for each test feeder. Each guide is developed through a partnership between Arizona State University researchers and XENDEE. These training guides have been successfully used to train people individually, in small and large classrooms, during interactive microgrid boot camps, and during short sessions for industry integrators and operators.

File Information

This package (IEEE34Node.zip) includes XENDEE model files (.xpf) that can be imported to create a personal XENDEE project library. Additional supporting files required for independent testing and verification are also provided.

IEEE_34_LVRauto.xpf – A XENDEE model that implements line voltage regulators (LVRs) as suggested by EPRI. Specifically, OpenDSS simulates tap changes and then recalculates power flow. Many other software tools complete power flow studies using only estimates of tap changes.

IEEE_34_LVRtapsFixed.xpf – A XENDEE model of the same network but with single-phase transformers with fixed tap settings defined to match IEEE data.
