“…Nacmanson et al [27] simulated a combination of a detailed high-voltage network with a low-voltage grid, determined from only the number of users, showing that EV penetration can reach up to 80% of residential costumers in urban grids, while rural grids can only sustain 40% penetration. Kurth et al [28] considered a rural grid with only seven households to simulate the load complementarity of EVs with small photovoltaic (PV) generation systems, demonstrating how the two systems can complement each other to keep the voltage levels of the entire grid within the allowed limits. Among the cases studied, they did not consider the exclusive use of EV chargers without the support of PV systems.…”

The electric vehicle deployment, due to the plans defined according to the energy transition objectives, produces new challenges for the electrical system. These challenges are associated with the charging infrastructure of these vehicles since they require a high current during specific periods, which can increase losses in the network, overload the lines, or cause voltage drops that affect the system’s stability. To solve these challenges, one of the possible solutions is the investment in new network infrastructure to face the increase in demand, such as the construction of new transformation centers or new medium and low-voltage lines. However, in the case of rural networks with a small number of users, these investments may not be viable. This article analyzes the possible impacts of connecting electric vehicles in a rural low-voltage network located in a Spanish municipality, as well as possible implementable solutions that do not require investment in new infrastructure. The number of connected vehicles has been calculated based on the national plan for 2030, and the network model used is based on actual data provided by the distribution company that operates in the area.
