PSCE Paper describing DG Protection Test Case. Based on a real system, it contains among other things a segment of line with 4 circuits sharing a common neutral. Neutral-Earth-Voltage (NEV) Test Feeder: This tests the capability of a program to represent very detailed models of a distribution system. 1-, 2-, 3-phase and split-phase circuits yielding over 8500 total node points. 2500 primary (MV) buses, 4800 total buses including secondaries (LV) and loads. 8500-Node Test Feeder: Will your algorithm scale up to large problems? Try it on this test feeder. : New solutions and model files available after solution agreements between WindMil and CYME. Comprehensive Test Feeder: This tests the capability of a program to represent a wide variety of components in one circuit. Provided by Tomas Yebra and Mayssam Amiri (University of Manitoba). : Added line configuration for line 51-151. 16 Sept 2010: Matrices for Config 2 and 4 corrected. 15 Sept 2010: Node 49, Phase C load changed from 25 kvar to 20 kvar. This circuit is “well-behaved” with minimal convergence problems. This circuit is characterized by overhead and underground lines, unbalanced loading with constant current, impedance, and power, four voltage regulators, shunt capacitor banks, and multiple switches. While this is not a popular voltage level it does provide voltage drop problems that must be solved with the application of voltage regulators and shunt capacitors. 123-bus Feeder: The IEEE 123 node test feeder operates at a nominal voltage of 4.16 kV. This circuit configuration is fairly uncommon. It is characterized by delta configured, all line segments are underground, substation voltage regulation is two single-phase open-delta regulators, spot loads, and very unbalanced. 37-bus Feeder: This feeder is an actual feeder in California, with a 4.8 kV operating voltage. 17 Sept 2010: Error regarding branch 858-864 corrected. It is characterized by long and lightly loaded, two in-line regulators, an in-line transformer for short 4.16 kV section, unbalanced loading, and shunt capacitors. 34-bus Feeder: This feeder is an actual feeder located in Arizona, with a nominal voltage of 24.9 kV. It is characterized by being short, relatively highly loaded, a single voltage regulator at the substation, overhead and underground lines, shunt capacitors, an in-line transformer, and unbalanced loading. 13-bus Feeder: This circuit model is very small and used to test common features of distribution analysis software, operating at 4.16 kV. Each of these represent reduced-order models of an actual distribution circuit. 
These systems were designed to evaluate and benchmark algorithms in solving unbalanced three-phase radial systems. These systems were originally created in 1992 and approved by the DSA Subcommittee during the 2000 PES Summer Meeting.
04 Sept 2012: Wye-Delta Center Tapped Xfm Test Feeder.doc,, Neutral conductor resistance changed from 0.492 to 0.592 Ohms/mile. A good match would have an error less than 0.05%. Since the problems are so small, very close agreement with the test feeder results is expected.

4-Bus Test Feeder Cases: These test the capability of a program to represent transformers of various configurations, full three phase lines, and unbalanced loads. The zipped data files require Microsoft Word and Microsoft Excel to read them. The original test feeder paper and data are provided below. McDermott, and W Kersting, “Analytic Considerations and Design Basis for the IEEE Distribution Test Feeders,” IEEE Transactions on Power Systems, vol. NEWS: New journal article published summarizing working group efforts and intended uses of Test Feeders.
