I. Introduction
The additional incentives and supportive regulatory frameworks of several countries encouraged electric vehicle (EV) diffusion, despite the global car sales drop due to the pandemic [1]. Thus, the increasing number of integrated charging stations affect the distribution grid operation, since connected EV charging demand modifies grid global load profiles. Several studies focused on the effects of EV integration into power grids, in terms of load profile, voltage profile and harmonic distortion [2]. Another potential effect is registered in [3] on transformer performances, especially considering EV uncoordinated charging. In [4] the impact of EV integration on a low voltage distribution network is evaluated considering different EV penetration levels and showing that the uncoordinated charging implies the infrastructure upgrade, with respect to the case of EV coordinated charging. The possibility to control EV charging, in order to minimize total energy losses, has also effects on improving distributed generation into distribution networks [5]. Furthermore, in [6] EV charging stations are integrated into the optimization model of economic dispatch as flexible loads with price elasticity, confirming that the charging loads is able to avoid grid congestions.
