Optimum placement of the distribution transformer with QGIS software with the aim of reducing the voltage drop and analyzing the section using the back-and-forth sweeper algorithm (sample network of five feeders in Farsan city)

One of the missions of electricity distribution companies is to minimize losses and deliver energy with high reliability to subscribers. Installing a new transformer in the distribution network is one of the ways to reduce losses and voltage drop in the weak pressure network. Optimum placement of the transformer requires monitoring of various components such as losses, determination of the contribution of each feeder and energy consumption area to the total amount of network losses, the number of subscribers on each feeder and the length of the feeder. In this article, we present a quick and practical method with QGIS software to locate the transformer by considering the center of gravity of the load, and then analyze the load section with the round-trip sweeper algorithm.
