Power Flow Calculation Program for 33-Node Distribution Network with Integrated Data

The power flow calculation program for 33-node distribution networks provides an efficient solution for network performance analysis and optimization. This MATLAB-based implementation utilizes the forward-backward sweep algorithm specifically designed for radial distribution systems, featuring automatic data handling for the standard IEEE 33-bus test case. The program calculates voltage profiles, power losses, and branch currents through iterative computations that ensure convergence for weakly meshed networks. Key implementation features include: - Automated data parsing for node parameters, line impedances, and load specifications - Robust convergence handling with configurable tolerance settings - Power flow visualization capabilities for voltage magnitude and angle distributions - Loss calculation modules for technical and economic analysis The pre-configured 33-node dataset follows the standard IEEE test case structure, including balanced three-phase load data and network topology information. This allows engineers to immediately perform baseline analyses or modify parameters for scenario studies. The program's modular architecture supports easy integration of distributed generation units, capacitor banks, and other network components. Whether for educational purposes or professional grid analysis, this tool provides accurate power flow results essential for identifying voltage violations, optimizing network configuration, and planning system upgrades. The code includes comprehensive documentation and example cases to facilitate rapid adoption by both experienced power system engineers and newcomers to distribution network analysis.
