IEEE 14-Bus Power Flow Calculation with Expandable Node Support

This program implements a comprehensive power flow calculation solution for the IEEE 14-bus test system using Newton-Raphson or Gauss-Seidel numerical methods. The architecture employs modular data input structures where the base case data module can be easily replaced with alternative standard test cases including IEEE 30-bus, 57-bus, and other common power system benchmarks. Matrix variables within the codebase utilize Chinese pinyin naming conventions (e.g., "Juzhen" for matrix operations, "Daoshuyi" for admittance matrices) to maintain regional coding practices while ensuring computational accuracy. The implementation features robust convergence control algorithms and includes functions for Jacobian matrix formation, power mismatch calculations, and voltage correction iterations. This tool delivers precise power flow results with reliable performance for power system analysis, supporting both research and educational applications in electrical engineering.
