MATLAB-Based Power System Newton Power Flow Source Code

This MATLAB-based power flow calculation program employs Newton's iterative method for solving power system load flow problems. The implementation features sophisticated mathematical modeling of electrical network components, including resistance and reactance parameters for transmission lines, transformers, and generators. The algorithm utilizes the Newton-Raphson method to solve the nonlinear power flow equations through iterative Jacobian matrix updates, ensuring quadratic convergence characteristics. The program provides electrical engineers with accurate power flow distribution analysis, enabling comprehensive system operational assessment. Key computational functions include admittance matrix formation, power mismatch calculations, and voltage correction updates at each iteration cycle. The implementation handles various bus types (PQ, PV, and slack buses) with appropriate constraint handling in the solution algorithm. For enhanced usability, the program incorporates a structured data input system for network parameters and includes visualization components for result interpretation. The modular code architecture allows for easy integration of additional features like contingency analysis or optimal power flow extensions. Engineers can efficiently evaluate system stability, reliability margins, and perform network optimization studies through this computational framework.
