“…In contrast, our contribution presents a more durable solution by adding a cable that operates as a unipolar LVDC backbone where PV systems, BESS and EVs could be connected. While the scope of the presented work does not consider harmonic distortion, Marah et al [23] highlight the importance of mitigating the adverse impact on the overall network's power quality due to electric vehicle charging stations. Similarly, the impact of harmonic currents caused by electric vehicles is assessed in [24], demonstrating that the power quality could be jeopardized and thus influence the degradation of the low-voltage distribution transformers.…”

This paper presents an in-depth comparison of the benefits and limitations of using a low-voltage DC (LVDC) microgrid versus an AC microgrid with regard to the integration of low-carbon technologies. To this end, a novel approach for charging electric vehicles (EVs) on low-voltage distribution networks by utilizing an LVDC backbone is discussed. The global aim of the conducted study is to investigate the overall energy losses as well as voltage stability problems on DC and AC microgrids. Both architectures are assessed and compared to each other by performing a power flow analysis. Along this line, an actual low-voltage distribution network with various penetration levels of EVs, combined with photovoltaic (PV) systems and battery energy storage systems is considered. Obtained results indicate significant power quality improvements in voltage imbalances and conversion losses thanks to the proposed backbone. Moreover, the study concludes with a discussion of the impact level of EVs and PVs penetration degrees on energy efficiency, besides charging power levels’ impact on local self-consumption reduction of the studied system. The outcomes of the study can provide extensive insights for hybrid microgrid and EV charging infrastructure designers in a holistic manner in all aspects.

“…DC fast charging stations, for example, can require more than 50 kilowatts of power per vehicle and up to several megawatts per charging station, which is roughly equivalent to adding the peak load of several thousand homes at a single point on the distribution grid. Prior analysis has identified potential issues with steady-state voltage violations, equipment overloading, and in some cases, power quality and transient voltage stability with deployment of electric vehicle charging stations (Nour et al 2018;Bass and Zimmerman 2013;Marah et al 2016;Mehmedalic, Rasmussen, and Harbo 2013;Wamburu et al 2018). Even the spatial clustering of residential electric vehicle (EV) charging could introduce challenges for distribution systems (Muratori 2018), such as the potential need to upgrade distribute system infrastructure.…”

“…Also, they considered fast-charging stations in an IEEE 33 bus test system and evaluated the effect of fast charging behavior in such systems. As another sample, the effect of electric vehicle charging systems has been examined on modern low voltage distribution networks by [22]. This paper has evaluated the power factor and harmonic distortions of EV charging stations as the main aim of the research.…”

Electric vehicles (EVs) have received special consideration from modern society over the past several years. Although EVs are a fine example of environmentally friendly technology and have many advantages, they relatively increase the electricity demand upon a power grid as well. Therefore, their negative impact on busvoltage and line losses should be analyzed. In this study, the effect of EV loads and their penetration on bus voltage and line losses of an IEEE-33 bussystem has been examined via two scenarios. It is important to mention that the effect of EVs on the rate of air pollution, produced by fossil fuel electricity generators, has been investigated throughout the study. Also, the key role of demand response programs in the reduction of EVs' negative effects on the grid has also been discussed in the last scenario. Generally, the simulation of this paper provides a novel and wider perspective on EVs and their effect on grids and environmental pollution.
