The IEEE 8500-node test feeder

IEEE test cases provide a benchmark for power systems analyses community. The 8500-node test feeder represents a large radial distribution feeder which provides a challenging circuit for distribution studies. The 8500-node test feeder includes many elements that may be found on a North American medium voltage (MV) distribution feeder: multiple feeder regulators, per-phase capacitor control, feeder secondaries, and service transformers. The test feeder description and results are provided herein.
