Newton-Raphson Power Flow Calculation Program

This code implements a power flow calculation program based on the Newton-Raphson method algorithm. It performs power flow analysis in electrical power systems to compute key parameters including node voltages, branch currents, and active/reactive power distributions. The implementation features a modular Newton-Raphson solver that handles the nonlinear power flow equations through iterative Jacobian matrix updates and mismatch calculations. To utilize this program effectively, users should possess fundamental knowledge of power system analysis and numerical methods. The code architecture supports customization through additional computational modules or modifications to existing calculation components. Key functions include bus admittance matrix formation, power mismatch computation, and voltage correction updates through partial derivative matrices. The package includes comprehensive documentation covering program usage guidelines, configuration parameters, and troubleshooting procedures for common numerical convergence issues. Error handling mechanisms address singularity detection in Jacobian matrices and convergence monitoring for iterative solutions.
