“…Most of the EVs have the capability of regenerative braking, which can reduce external energy consumption by 20% in urban areas. [14][15][16] Coordinated or controlled charging of EV can be used to alleviate issues arisen from the uncontrolled charging.

Summary With the recent breakthroughs in battery technology and large scale production, electric vehicles (EVs) are becoming cheaper. In a few years, mass deployment of EVs will put severe stress on the electricity network. Charging of EV during peak hours may overload the distribution grid transformer, and EV owners may have to pay more money for electricity during peak hours. To address these issues, a coordinated scheduling model is proposed in this paper. A mathematical model is formulated to minimise the charging cost of each EV while satisfying the constraints. In this work, time of use (ToU) tariff from the utility and actual power demand from household and EVs are used to conduct simulation for one week in summer and winter season with different levels of EV penetration. The results demonstrate that the proposed scheduling model can significantly reduce the charging cost for the EV owner and power peaks in the distribution network.

“…In 2013, Jiang, et al, developed a comprehensive probabilistic approach based on Monte Carlo simulation to evaluate the impact of EV battery chargers in the distribution network in [18], which considers randomness in parameters such as the charging time, charging duration and location of vehicles. Moreover, a simple forecast model of EV penetration based on consumer trends is presented to study future scenarios.…”

The air in most large Latin American cities is polluted, primarily because their automotive fleet is composed of internal-combustion engine vehicles. This also implies a strong fossil-fuel dependency. Petroleum fuels are nonrenewable and, as a consequence, the current mobility model becomes unsustainable. Great expectations have been put in electric vehicles. Such vehicles are already penetrating the automotive market and, soon, will be part of the alternatives of mobility in countries of Latin America. Therefore, research and development efforts must be conducted in order to facilitate the transition between the old technology, of internal-combustion engine vehicles, to the new e-mobility technology, in an efficient and effective way. At the Instituto de Energía Eléctrica, a threeyear research project has begun. The scope of the project includes the analysis of potential impacts of massive penetration of electric vehicles on both: the power system and the way in which it is traditionally operated. In this paper, a partial result of the natural first step in a scientific research is presented, that is a literature/bibliographic review. The paper focuses on three main issues: the impacts on the network planning, on the power quality and on the tariff schemes. After a brief introduction and a quantitative analysis of the available literature on the subject, each one of the issues is separately presented. Finally, the conclusions of the paper are given. Index Terms-Network planning, Plug-in electric vehicle, Plug-in hybrid electric vehicle, Power Quality, Reliability, Smart Grid, Tariff, Time of use.

Electric vehicles (EVs) play a significant role in a gradual shift towards low-carbon society. However, the impact of electromobility on a power system includes different power quality problems that need to be mitigated. Power Quality Analyzer SONEL PQM-700 was used for the measurement and analysis of the power quality parameters during slow charging (at ~11A, ~8,3 A and ~5,5 A) of a BMW i3 electric vehicle. The read-out mode of the device was considered. The state of EV charge was 30%. The measurements focused on the values of supply voltage, drawn current, harmonics, values of active, reactive and apparent power. In this study, type 2 connector was used to charge the EV. The power quality parameters during the BMW i3 charging were within limits, not a single parameter was exceeded. Additionally, the current state of electric vehicle charging methods and EV charging infrastructure was described and power conditioning solutions were presented.
