Robust Energy Scheduling in Vehicle-to-Grid Networks
2017
The uncertainties brought by intermittent renewable generation and uncoordinated charging behaviors of EVs pose great challenges to the reliable operation of power systems, which motivates us to explore the integration of robust optimization with energy scheduling in V2G networks. In this article, we first introduce V2G robust energy scheduling problems and review the stateof- the art contributions from the perspectives of renewable energy integration, ancillary service provision, and proactive demand-side participation in the electricity market. Second, for each category of V2G applications, the corresponding problem formulations, robust solution concepts, and design approaches are describ…
An efficient wireless power transfer prototype for electrical vehicles
2017
Based on the inductive power transfer (IPT), the contactless approach allows safe and comfortable operations of battery charging for Electric Vehicles (EVs). In this paper, a contactless system particularly suitable for E-bike battery charging is proposed. A practical realization of the system has been carried out, aiming at the system evaluation in terms of working and efficiency. Through a phase shift modulation, a power regulation has been implemented. The target power level is 100 W.
Ev charging station at university campus
2017
This paper faces the technical and economic challenges related to the design of a green recharge area for electric vehicles at the Campus of Palermo, Italy, with the aim of reduce both costs and pollution connected to the charging process. Based on the behaviour of the student population, the electrical load is identified and two possible solutions are evaluated to manage the peak load: an orientation of the panels increasing the power at defined time and the use of a storage system. The main strength and weakness points of two systems are investigated by taking into account the Levelized Cost of Energy (LCOE), which reaches 75.3 â¬/MWh for the orientation of panel and 103 â¬/MWh for stor…
Master-Slave Control of Battery/Supercapacitor Based Hybrid Energy Storage System for E-Vehicle Application
2022
In this paper, management and control problem of hybrid energy storage system (HESS) has been solved by master-slave control strategy. Heuristic fuzzy rules based algorithm is developed for optimal power sharing between different power sources. The master control is followed by a slave level controller, designed by using terminal synergetic control method for tracking. Moreover, the stability analysis of closed-loop system has been carried out by using lyapunov theory. Finally, the proposed method has been tested in MATLAB/Simulink environment under Worldwide Harmonised Light Vehicle Test Procedure (WLTP).
Factors Affecting the Consumers’ Purchase Intention and Willingness-to-Pay More for Electric-Vehicle Technology
2021
This study conducted an in-depth analysis of the factors affecting consumers’ intention to purchase and willingness to pay more for an electric vehicle (EV) in the developing-country context, extending the theory of planned behavior with two new variables: environmental concern and willingness to pay (WTP) a premium. Survey data were collected from 358 responses and were analyzed using partial least squares structural equation modeling. Multi-group analysis was conducted, and the moderating role of gender was examined. The findings showed the significant effects of the theory-of-planned-behavior variables and environmental concern on EV technology purchase intention. The present study provi…
Priority Based Coordinated Electric Vehicle Charging System for Heterogeneous Traffic
2020
Despite the environmental and health merits associated with Electric vehicles (EVs), a massive deployment of EVs tends to create new technical and economic challenges for power systems. This is being addressed with different coordinated charging schemes where the charging coordination is distributed across multiple EVs and/or aggregators based on different objectives. This work analyzes an algorithm which maximize the operational profit of a charging station with a high charging station utilization while adhering all the constraints enforced by the utility grid. And it is analyzed the performance of the coordinated charging scheme which facilitates heterogeneous EV users whose arrival is un…
Different scenarios of electric mobility: Current situation and possible future developments of fuel cell vehicles in Italy
2020
The diffusion of electric vehicles in Italy has started but some complications weight its spread. At present, hybrid technology is the most followed by users, due particularly to socioeconomic factors such as cost of investment and range anxiety. After a deep discussion of the Italian scenario, the aim of the paper is to recognize whether fuel cell technology may be an enabling solution to overcome pollution problems and respect for the environment. The opportunity to use fuel cells to store electric energy is quite fascinating&mdash
Design and simulation of a fast DC recharging station for EV
2017
In this paper a detailed description of the design and simulation of a DC ultra-fast recharging station for Electric Vehicles is carried out. The system consist of a single AC/DC grid connected inverter, a DC-Bus and two DC/DC converter to recharge the batteries of the EVs. The system also has the vehicleto- grid (V2G) capability. The design of the components of the system and the control schemes are explained and a simulation of the system, performed in Matlab/Simulink environment is presented.
The Role of Technology in Participative Processes
2016
Smart city is more and more, in the common feeling, the crossroad of technologies, but first and foremost, the place where humans, contexts and technologies meet and must interact. Technological systems thanks to the deep human interaction acquire an uncertain behaviour that can be hardly modelled and controlled. The resulting complexity, cannot be easily handled with the tools that are available to separate scientific fields. The interdisciplinarity that comes from the implementation of technologies and the dialogue between these and the territories requires new tools for classification and design. New urban design tools are needed allowing to identify in a standardized way adequate suppor…
Electric-Motion in Romania - Overview - Study on Machining Parameters of EV Charging Station Mechanical Components
2016
This paper presents some relevant aspects of charging infrastructure for electric vehicles in Romania. It evidences the charging station and fast charging stations designed and installed by the first Romanian company dedicated 100% to e-mobility, E-Motion Electric. Also, a study on machining (milling) parameters of some mechanical components of electric vehicle (EV) charging station is done and, finally, the regression model for these parameters is determined. This model would be further used for machining process optimization.
