Distribution Network Power Flow Calculation Program Using Forward-Backward Sweep Method

This distribution network power flow calculation program implements the forward-backward sweep method, specifically designed for radial open-loop power flow calculations in networks below 35kV. The algorithm implementation includes automatic handling of parallel backup branches through equivalent single-branch conversion prior to calculation. The program is optimized for loop-free network configurations, with detailed usage instructions and procedural steps available in the comprehensive program documentation. Key algorithmic features include efficient processing of diverse power flow calculation scenarios, significantly reducing manual effort and time requirements. The program incorporates automatic error detection mechanisms that identify common power flow calculation issues and provide effective solution strategies. The implementation includes an intuitive visualization interface that enables users to clearly observe the complete power flow calculation process and interpret results effectively. From a technical perspective, the forward-backward sweep algorithm operates through two main phases: the forward sweep propagates voltage magnitudes from the root node to terminal nodes, while the backward sweep calculates branch power flows from terminal nodes back to the root node. This iterative process continues until convergence criteria are met. Overall, this program represents an efficient, intelligent, and user-friendly power flow calculation tool that assists users in completing various power flow analysis tasks with enhanced accuracy and reduced computational complexity. The code structure ensures reliable performance while maintaining computational efficiency through optimized matrix operations and convergence acceleration techniques.
