  Global warming leads the world to think of a different way of transportation:
avoiding internal combustion engines and electrifying the transportation
sector. With a high penetration of electric vehicle (EV) charging stations on
an existing power distribution network, the impact may be consistent. The loads
of the fast-charging stations would potentially result in increased peak load
demand, reduced reserve margins, voltage instability, and reliability problems.
The degrading performance of the power system due to the negative impact of the
EV charging stations can even lead to penalties to be paid by the distribution
system operator (DSO). This paper: i) investigates the impact of the \ac{ev}
charging station on the distribution network for what concerns voltage drop on
MV feeders and loading of transformers in primary substations, and ii) proposes
a mitigation mechanism. A realistic typical Italian grid has been used to
assess the impact of EV charging stations and to validate the mitigation
mechanism.
