Distribution Network Power Flow Calculation Using Forward-Backward Sweep Algorithm

In power systems, distribution networks serve as critical components connecting power generation and consumption. Consequently, power flow calculation for distribution networks represents one of the core tasks in power system operation and management. The forward-backward sweep algorithm-based distribution network power flow calculation is a classical approach that enables rapid and accurate computation of current distribution within the network. The algorithm implementation typically involves iterative voltage updates at nodes and current calculations along branches, ensuring convergence through successive refinement. This method's source code can be widely applied across various domains of power systems, including load forecasting, grid planning and optimization, and electricity market analysis. The code structure generally incorporates bus admittance matrix formation, convergence criteria checks, and power loss calculations. Therefore, proficiency in both the algorithm and its programming implementation is essential for power engineers and researchers.
