Type: article

Abstract: Considering the diverse connection modes and complex control strategies of photovoltaic (PV) inverter power sources integrated into low-voltage distribution networks, this paper delves into the establishment of a control model for the three-phase voltages and powers of PV inverter power sources relative to the neutral point. On this foundation, the paper further proposes a comprehensive low-voltage distribution network three-phase power flow calculation model that takes into account both the asymmetry of phase angles at balanced terminals and the factors involved in the integration of PV inverter power sources. To validate the effectiveness and accuracy of this model, simulation experiments were conducted on a modified IEEE-13 node test system. The simulation results clearly demonstrate that the model constructed in this paper can accurately and efficiently calculate the three-phase power flow in low-voltage distribution networks incorporating PV inverter power sources, providing robust theoretical support and technical means for the planning and operation of low-voltage distribution networks.
