“…A novel electric vehicle (EV) classification scheme for a photovoltaic (PV)-powered EV charging station (CS), that reduces the effect of intermittency of electricity supply and the cost of energy trading of the CS is proposed in [12]. An analysis of electric vehicle charging impact on the electric power grid based on smart grid regional demonstration project in Los Angeles is done in [13]. This paper presents monitoring of actual EV charging behavior of 64 EV owners (5 brands, 8 models) and charging stations for more than one year.…”

The rapid increase in the number of electric vehicles around the world, the high demands on the charging stations, and the challenges for locating the charging stations made researchers around the globe to think for a proper solution. In this paper, a new method to locate EV's charging infrastructures, based on the parallelism between mobility needs and heat equation implemented with Finite Element Method analysis (FEM), is proposed. The method is applied for two cities with similar metropolitan area: Boston (USA) and Milan (Italy), with further results. Although FEM is a mathematical tool for solving physical problems, the behavior of different parameters in this paper is modeled as physical objects. In addition, the parameters are modeled according to the heat equation. Heat density maps are elaborated for the considered case studies. The two cities with extremely different characteristics are chosen to demonstrate the general application of the proposed method. Heat density maps show the likely demand points to establish charging infrastructures for EV's. The annual electricity consumption maps of the two considered cities are reported. The analysis of heat density and electricity consumption maps, together with the considerations of mains supply capacity can give a perspective for the location of charging stations in the future urban environments. The developed method contributes to deploy charging stations in an urban environment.

“…The additional charging demand generated by electric vehicles during evening peak load times can be particularly problematic. In addition, based on actual electric vehicle charging behavior in intelligent grid regional demonstration project in Los Angeles, the effects of electric carloads on the California distribution network are evaluated at different electric vehicle penetration levels [10]. In [11], Wussow et al presented a methodology for modeling and analyzing the load in a distribution system considering grid-oriented charging of electric vehicles and adopted simulations in an extreme scenario.…”

This paper seeks to identify bottlenecks in the energy grid supply regarding different market penetration of battery electric vehicles in Stuttgart, Germany. First, medium-term forecasts of electric and hybrid vehicles and the corresponding charging infrastructure are issued from 2017 to 2030, resulting in a share of 27% electric vehicles by 2030 in the Stuttgart region. Next, interactions between electric vehicles and the local energy system in Stuttgart were examined, comparing different development scenarios in the mobility sector. Further, a travel demand model was used to generate charging profiles of electric vehicles under consideration of mobility patterns. The charging demand was combined with standard household load profiles and a load flow analysis of the peak hour was carried out for a quarter comprising 349 households. The simulation shows that a higher charging capacity can lead to a lower transformer utilization, as charging and household peak load may fall temporally apart. Finally, it was examined whether the existing infrastructure is suitable to meet future demand focusing on the transformer reserve capacity. Overall, the need for action is limited; only 10% of the approximately 560 sub-grids were identified as potential weak points.

“…Despite the advantages of the vehicle electrification for the smart grids, its impact on the electrical grid operation is of utmost importance and must be handled properly [50][51][52][53]. An on-line adaptive strategy for coordinating the EV parking schedules, in the perspective of maintaining the operability of the electrical grid, as well as the user convenience, is proposed in [54].…”
