“…Several EV integration studies [4]- [10] have analyzed the existing and planned generation capacity to meet current and future EV demands. These studies conclude that if EVs are charged during off-peak load hours, new power plants will not be required to meet EV charging demand.…”

“…2) EV Load Impacts on Transformer Aging Large-scale EV deployment is likely to cause problems in the distribution system such as increased load demand, increased system losses, and additional voltage drops [10]- [28]. The increased load demand due to EV loads can overload service transformers, deteriorate the transformers' life, and increase system losses.…”

“…Therefore, both a system level analysis of the impacts of EV integration on the residential distribution circuit and solutions to address their impacts are needed. EV integration studies in the literature have primarily focused on evaluating the impacts of EV loads on 1) electricity generation adequacy [4]- [10], 2) transformer aging [10]- [14], and 3) distribution system power quality [10]- [28]. In section II, a short literature review of these three issues is presented.…”

This paper aims to understand, identify, and mitigate the impacts of residential electric vehicle (EV) charging on distribution system voltages. A thorough literature review on the impacts of residential EV charging is presented, followed by a proposed method for evaluating the impacts of EV loads on distribution system voltage quality. Practical solutions to mitigate EV load impacts are discussed as well including infrastructural changes and indirect controlled charging with Time-of-Use (TOU) pricing. An optimal TOU schedule is also presented, with the aim of maximizing both customer and utility benefits. The paper also presents a discussion on implementing smart charging algorithms to directly control EV charging rates and EV charging starting times. Finally, a controlled charging algorithm is proposed to improve voltage quality at the EV load locations while avoiding customer inconvenience. The proposed method significantly decreases the impacts of EV load charging on system peak load demand and feeder voltages.

“…Different penetration levels of PEVs have been considered. Reference [14] obtained that the capacity of this network for EV charging station is equal to 1.2 MW, in case of unity power factor consideration. In this study, we have considered 20, 30, 40 and 50 % penetration level based on the maximum capacity of the charging station, to see the impact of PEVs charging demand's increment on voltage profile and losses in the lines.…”

In recent years, automobile industries focus on the electrification and hybridization of the vehicle's production. The number of Plug in Electric Vehicles (PEV) and Plug in Hybrid Electric Vehicles (PHEV) are significantly increasing through the next years. These raises impose negative impacts on the electrical power grids. In this study, a supervision system is proposed with the aim of reducing the power losses and voltage profile improvement, thanks to a dynamic programming optimization algorithm. V2G (Vehicle to Grid) technology is introduced as benefits of vehicle electrification for electrical distribution grids.  Index Terms-vehicle to grid (V2G), distribution network, PHEV, PEV, dynamic programming (DP), supervision system operator (SSO)

“…In the last COP21 meeting in Paris, the world policy leaders agreed to reduce greenhouse gas (GHG) emissions as soon as possible, to limit global warming below 2 o C, and strive towards keeping global warming below 1.5 o C [1]. Transportation electrification is one of the most promising ways to achieve these COP21s goals and to limit the CO2 emissions from the transportation sector [2]. An increasing number of electric vehicles (EVs) are expected to enter to the transportation market [3].…”

In this paper we present a solution for an interconnected micro grid's design including electrical vehicles. This micro grid is oriented to be placed in Guayaquil-Ecuador and integrates electric vehicle charge stations, a photovoltaic generator, a thermal unit, a battery energy storage system and an interconnection point to a distribution network. Moreover, the proposed microgrid includes an electric vehicle fleet oriented for the commercial sector. The model takes advantage of renewable resource generated locally (photovoltaic solar energy). This helps us to minimize the purchases from distribution network and to reduce costs for electric vehicles charging. Technical and economic considerations are taken into account in the present analysis. Additionally, the model minimizes the greenhouse gas emissions including as an input a tax rate for emissions. The simulations results allow us to determine the minimal cost of implementing the microgrid and the optimal strategies to reduce the implicit cost of integrating electric vehicles in the network.
