Practical 118-Node Distribution System Dataset

Processed topology, impedance, and load data for a practical 118-node distribution system modeled from two feeders in a city in Zhejiang Province, China.

GitHub About

Processed practical 118-node distribution-system dataset from two feeders in Zhejiang, China, with confidential load and impedance data sanitized for public research use.

Data Disclosure

The system topology is based on two practical distribution feeders from a city in Zhejiang Province, China. For security and confidentiality, the released load and line-impedance values are processed versions of the original field data rather than direct disclosure of operational measurements.

Files

• matlab/bus_118.mat: original MATLAB MAT file containing the bus matrix.
• matlab/branch_118.mat: original MATLAB MAT file containing the branch matrix.
• matlab/practical_118_node_system_data.m: MATLAB function returning all processed data and metadata.
• matlab/practical_118_node_system_data.py: Python module returning the same data as NumPy arrays.

MATLAB Usage

data = practical_118_node_system_data();
bus = data.bus;
branch = data.branch;
topology = data.topology;
line_impedance = data.line_impedance_ohm;
load_data = data.load_kW_kVAr;

Python Usage

case = load_case()
bus = case.bus
branch = case.branch
topology = case.topology
line_impedance = case.line_impedance_ohm
load_data = case.load_kW_kVAr
