In recent years, there has been a significant increase in incentives for using electric vehicles, especially in large urban centers, resulting in an increase in demand for residential chargers installed on low-voltage networks. However, the installation of these chargers can affect the allocation planning of data concentrators based on power line communication (PLC) technology, since they share the same infrastructure as the distribution network. In this context, this work presents a methodology for allocating PLC data concentrators considering the growing insertion of residential electric vehicle chargers. Different electrical load scenarios are considered, considering the number of electric vehicles connected to the grid, energy consumption, and other factors that could influence them. A test low-voltage distribution network was used to apply the proposed methodology, which contains 15 nodes and 45 connected end users, some of which have photovoltaic generation. The results of applying the proposed methodology show that the insertion of 20% of residential electric vehicle chargers into the network can affect the allocation planning of PLC data concentrators, leading to a considerable increase in the number of data concentrators required. Specifically, the addition of more than 80% of data concentrators may be required, resulting in an increase of more than double the initial cost.
