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.

“…This can be brought down to 7 Euro cents/KWh with off-peak charging and with higher renewables and low general costs, down to 5.6 Euro cents/KWh. Mahalik et al [14] performed a simulation to realize EV impacts on the Illinois grid in 2020 and concluded that on-peak uncontrolled charging would require an additional 400 MW unit to support the state's reserve margin. If off-peak and controlled charging is facilitated, no additional supporting grid would be needed.…”

The idea of grid friendly charging is to use electricity from the grid to charge batteries when electricity is available in surplus and cheap. There are several ways of achieving this, for example using droop control, using night time electricity tariffs, or using smart metering. The goal is twofold: to avoid putting additional load on the electricity grid and power generation, and to reduce the cost to the consumer. This paper looks at the saving potential when charging an electric car using real time tariffs provided by a smart meter, using the Ameren tariffs in Illinois as an example. If prices are known in advance (day-ahead pricing), the optimization only requires picking the cheapest time slots for charging the battery. Further savings can be made by using real time prices that are not known in advance, but the optimization problem then depends on price prediction models, and it becomes much more difficult to solve. This paper presents a simple suboptimal approach, and it quantifies the potential improvements that could be made using more sophisticated price predictions.The result is that cost savings in the order of about 50 USD (1/3 of the electricity costs) are feasible if a fast charger is used using real time pricing. The scale of the savings is such that complex optimization strategies are not worthwhile, and for the foreseeable future simple solutions are expected to be more cost effective.

“…It revealed that every 10% increase of EV penetration created an 18% increase in maximum demand when uncontrolled charging had taken place. On the other hand, an impact study on the electricity grid in Illinois [27] concluded that the total increment in network load would be 0.8% for a maximum EV market penetration of 10%, by 2020. It confirmed that an addition of 400 MW generation to the grid would be sufficient even if EVs tended to charge on-peak.…”

Electric vehicle integration - grid stability concerns and countermeasures

The electrification of transportation has become a sustainable solution to the global economic and environmental challenges associated with the fossil fuel-dependent transportation. Substantial electric vehicle (EV) integration has resulted in the recent past owing to the distinct advantages and various incentives provided by governments. It can be expected that EV penetration will further accelerate along with technological advancements. This strategic shift of primary source of transportation energy from oil pipelines to power grids will inevitably bring numerous challenges to power grids around the world. The potential impacts of EV integration on power grids are yet to be discovered. This research concentrated on modelling the EV charging load, evaluating its impact on power system stability and identifying remedies. Further, two computationally efficient indexes were developed to identify voltage stability and oscillatory stability prudent charging solutions. A comprehensive EV charging infrastructure planning strategy was also developed. This research investigated the probable grid impacts associated with EV charging by comprehensively reviewing the available literature. Even though there were number of system studies on wide variety of grid impacts, scant attention has been paid to impact of EV charging on system stability. Electrification of transportation brings significant load integration to the grid. Hence, it is important to understand the EV charging impact on power system stability.
