Power Flow Calculation Software Modified from MATPOWER

This power flow calculation software is derived from modifications to the MATPOWER framework. It implements multiple numerical algorithms to solve power flow problems for IEEE standard test cases ranging from 9 to 300 buses, including DC power flow approximation, Newton-Raphson method for precise AC solutions, Fast Decoupled (PQ) decomposition method for improved computational efficiency, and Gauss-Seidel iterative technique for sequential calculations. The software maintains MATPOWER's core data structure using MATLAB's bus, branch, and generator matrices while extending solution capabilities through customized power flow solver functions. By leveraging this enhanced toolkit, users can perform power flow analyses more conveniently while obtaining accurate results validated against standard test cases. Whether for power system planning studies or operational control applications, this software provides valuable computational support with configurable algorithm selection and detailed convergence reporting.
