Analysis of the Impact of Power Grid Structure and Equipment Types on Distribution Losses

The structure of the power grid and the type of equipment are important components of the distribution network, which will affect the distribution of power flow and network losses. Based on the above factors, this article constructs a power grid model for simulation analysis. The simulation results show that selecting appropriate medium voltage line switch positions, power supply radii, branch stages, wire types, and substation transformer types can effectively reduce network losses in the distribution network and promote energy-saving and economic operation of the distribution network.
