Road transport electrification has a great potential to reduce greenhouse gas emissions and oil consumptions. However, massive integration of electric vehicles (EVs) may cause a trouble on power grid. This point of view looks at the future state of EV development, charging scheduling and drivers’ behaviors are becoming increasingly important to charging management strategy. An optimal charging management leads to minimum effects on power grid, reducing peak power via vehicle to grid (V2G) mode and lower charging costs. In order to make an optimum charging management strategy, it requires some information of driver behavior, such as daily driving, parking times and usage frequency of the vehicle. At this perspective, a campus based driver behavior is gathered with face to face survey in Yildiz Technical University, Turkey. Survey data is utilized to determine daily optimum charging profile and increase the functionality of EVs. In this study, the comparison of possible effects of different charging scenarios on power grid are presented and analyzed. A case study is performed in the university campus and the simulation is realized in MATLAB/Simulink environment with actual data.

This study considers whether electric vehicles (EVs) can be exploited as a flexibility management strategy to stimulate investments in and operation of renewable electricity under stringent CO2 constraints in four regions with different conditions for renewable electricity (Sweden, Germany, the UK, and Spain). The study applies a cost-minimisation investment model and an electricity dispatch model of the European electricity system, assuming three types of charging strategies for EVs. The results show that vehicle-to-grid (V2G), i.e., the possibility to discharging the EV batteries back to grid, facilitates an increase in investments and generation from solar photovoltaics (PVs) compare to the scenario without EVs, in all regions except Sweden. Without the possibility to store electricity in EV batteries across different days, which is a technical limitation of this type of model, EVs increase the share of wind power by only a few percentage points in Sweden, even if Sweden is a region with good conditions for wind power. Full electrification of the road transport sector, including also dynamic power transfer for trucks and buses, would decrease the need for investments in peak power in all four regions by at least 50%, as compared to a scenario without EVs or with uncontrolled charging of EVs, provided that an optimal charging strategy and V2G are implemented for the passenger vehicles.

Sustainable campuses have become one of the main objectives of agendas for a wide range of universities as a result of the impacts generated by the activities carried out within an academic life and how they directly affect the environment. An important aspect of the educational model of the International University of Ecuador, considering education as a focal transforming point of collective change, is to teach values and responsibility for the environment, considering that in terms of sustainability a higher education should not be understood only from the technical point of view, but as a process of realizing the significance of substantial values that would encourage future professionals to commit to the construction of a more fair and equitable society. For this reason, the objective of this study is to analyze sustainability through the implementation of electric mass transport vehicles in the internal route of the International University of Ecuador, for which the methodology is based on a quantitative approach, whose type of study is exploratory and of an inductive-deductive nature, analyzing the variables that directly influence a sustainable environment such as altitude above sea level (geographical location), benefited people, consumption and routes. Instruments such as sampling and surveys will be used to determine the decrease in polluting emissions that can affect the natural environment of the area. The technical considerations are the following: the location of the campus presents average slopes of 7.76 ° at 2560 masl, the results of autonomy in a route are 14.8 km benefiting around 450 people a day from the university community, having an annual load consumption of 297311 KWh during day hours and of 114715 KWh during night hours. With the implementation of an electric vehicle for the internal route, a power of 154.7 KW is required to overcome a slope of 18 ° with a campus route of 178.4 km, with this it would stop emitting 29.6 tons of CO2 and 0.76 tons of gases harmful for the environment per year

Electric Vehicles (EV) adoption targets have been set by governments from countries throughout Europe, related to the European goals, for the decarbonization of the road transport sector. The change for electric vehicle technology can be challenging to EV users for a number of reasons such as battery autonomy, time to charge the vehicle, and the different driving conditions. The work in this paper aims to study how users from Madeira and Porto Santo islands deal with the challenges of EV adoption. Furthermore, this paper also studies the role of the orography in the Regenerative Braking System technology integrated into electric vehicles. To assess such information, an online questionnaire was prepared and sent out to the electric vehicle community of both islands. The main results of this study show drivers’ preference to charge the vehicles at their household and that users are satisfied with the vehicle’s technology. Also, users’ battery range anxiety did not seem to have a significant impact. Moreover, from the drivers’ point of view, there is still the need to study the role of orography, while using the regenerative braking system.

Abstract: The increasing mobility of electric vehicles has inspired vehicle growth to power grid technology. Such as vehicle to grid technology allows to transfer the power from the electric vehicle battery to the power grid. This enable speak load shaving, load leveling, voltage regulation, and improved stability of the power system. To develop the vehicle to grid technology requires a specialized EV battery charger, which permits the bi-directional energy transfer between the power grid and the electric vehicle battery. There is a specific control strategy used for a bi-directional battery charger. The proposed control strategy is used for charge and discharge battery of EV. The charger strategy has two parts: 1) Bidirectional AC-DC Converter in two-way Communication System. 2) Bidirectional DC-DC Buck-Boost Converter. There are two modes of operation for a bidirectional ac-dc converter: for G2V, rectifying mode is used, and for V2G, inverter mode is used. The suggested charge strategy not only allows for two-directional power flow but also provides power quality management of the power grid. Fuzzy logic controller (FLC) transforms linguistic control topology evaluations knowledge into an automated control topology using FLC. The FLC is more stable, has less overshoot, and responds quickly. The operation of a standard PI controller and a FLC was compared in this study using MATLAB and Simulink, and different time domain characteristics were compared as toshow that the FLC had a smaller overshoot and a faster response than the PI controller. Keywords: Bi-directional AC-DC converter, bi-directional DC-DC Buck-Boost converter, electric vehicles (EVs), on-board battery charger (OBC), grid to vehicle (G2V), vehicle to grid (V2G).

Long Run

Although the increasing adoption of electric vehicles (EVs) is overall positive for the environment and for the sustainable use of resources, the extra effort that requires purchasing an EV when compared to an equivalent internal combustion engine (ICE) competitor make them less appealing from an economical point of view. In addition to that, there are other challenges in EVs (autonomy, battery, recharge time, etc.) that are non-existent in ICE vehicles. Nevertheless, the possibility of providing electricity to the power grid via vehicle-to-grid technology (V2G), along with lower maintenance costs, could prove that EVs are the most economically efficient option in the long run. Indeed, enabling V2G would make EVs capable of saving some costs for their vehicle owners, thus making them a better long-term mobility choice that could trigger deep changes in habits of vehicle owners. This paper describes a cost–benefit analysis of how consumers can make use of V2G solutions, in a way that they can use their vehicle for transport purposes and obtain revenues when injecting energy into the power grid.
