Multi-objective Distribution Network Reconfiguration Based on Backward/Forward Sweep-Based Power Flow Calculation

As an indispensable part of power system operation, distribution network fault recovery is of great significance to power supply reliability evaluation. In this paper, a fault recovery algorithm based on forward/backward sweep-based power flow calculation and improved genetic algorithm is proposed. This paper analyzes and establishes the distribution fault recovery model, which takes the minimum network loss and switch action times as the comprehensive objective function, and takes the distribution network topology, branch voltage and power as constraints. The specific steps of genetic algorithm for distribution network reconfiguration are given. The simulation results show that the method has good convergence and accuracy.
