Three-phase Power Flow Calculation and Static Voltage Stability Analysis of Low Voltage Distribution Network

The distribution network after new energy access has changed from a typical star-shaped structure to a multi-power structure, and power overpower and power quality have become new problems in low-voltage grid. Under this background, the power flow analysis of low-voltage distribution network has become a new demand. Due to the relatively short transmission lines and the disordered configuration of single-phase and three-phase users, it is necessary to use typical parameter schemes to quickly construct the distribution network topology. In this paper, the parameters of low-voltage lines are typically configured, and the power flow is calculated by ABC three-phase calculation.
