Wind-Energy-Powered Electric Vehicle Charging Stations: Resource Availability Data Analysis

Abstract

The integration of large-scale wind farms and large-scale charging stations for electric vehicles (EVs) into electricity grids necessitates energy storage support for both technologies. Matching the variability of the energy generation of wind farms with the demand variability of the EVs could potentially minimize the size and need for expensive energy storage technologies required to stabilize the grid. This paper investigates the feasibility of using the wind as a direct energy source to power EV charging stations. An interval-based approach corresponding to the time slot taken for EV charging is introduced for wind energy conversion and analyzed using different constraints and criteria, including the wind speed averaging time interval, various turbines manufacturers, and standard high-resolution wind speed datasets. A quasi-continuous wind turbine’s output energy is performed using a piecewise recursive approach to measure the EV charging effectiveness. Wind turbine analysis using two years of wind speed data shows that the application of direct wind-to-EV is able to provide sufficient constant power to supply the large-scale charging stations. The results presented in this paper confirm that the potential of direct powering of EV charging stations by wind has merits and that research in this direction is worth pursuing.

“…The proposed model minimized the levelized cost of electricity and the power supply loss considering the energy exchange to the utility grid. The paper [320] investigated an interval-based framework to identify the feasibility of leveraging wind energy to supply electricity to EV charging stations considering the time interval over which wind speed is averaged, various turbine manufacturers, and standard high-resolution datasets of wind speeds.…”

Optimal Power Management for Sustainable Multipurpose Smart EV Charging Stations

“…The charging station in this proposed system comprises of multiple renewable energy sources, including two wind turbines each with a capacity of 15kW, two grid-connected charging points with 15kW each, one solar-powered charging point with 20kW, and two fuel cell systems for backup power. The wind turbines are equipped with boost converters that regulate the output voltages, ensuring efficient charging of the EVs [5] [6]. The grid-connected charging points are designed to draw power from the grid.…”
