MATLAB-based implementation of Newton-Raphson power flow analysis, including PQ decoupling method and Fast PQ technique, demonstrated using IEEE 30-bus test system
Detailed Documentation
This article presents MATLAB implementations of power flow analysis methods including the Newton-Raphson technique, standard PQ decoupling approach, and Fast PQ method. Our implementation utilizes the IEEE 30-bus test system as a case study. The Newton-Raphson method employs iterative Jacobian matrix calculations to solve nonlinear power flow equations, while the PQ decoupling method separates active and reactive power computations for improved efficiency. Through these algorithms, we can accurately analyze power system load flow conditions, providing reliable guidance for power system design and operational decision-making. The MATLAB code features functions for bus admittance matrix formation, power mismatch calculations, and iterative solution convergence checking.
