Wind Data Analysis for Assessing the Potential of Off-Grid Direct EV Charging Stations

04/25/2020 ∙ by Fuad Noman, et al. ∙ 0

The integration of large-scale wind farms and large-scale charging stations for electric vehicles with the electricity grids necessitate energy storage support for both technologies. Matching the energy variability of the wind farms with the demand variability of the electric vehicles (EVs) off-grid could potentially eliminate the need for expensive energy storage technologies required to stabilize the grid. The objective of this paper is to investigate the feasibility of using wind generation as direct energy source to power the EV charging stations. An interval-based approach corresponding to the time slot of EV charging is introduced for wind energy conversion and analyzed using different constrains and criteria including, wind speed averaging time interval, various turbines manufacturers, and standard high-resolution wind speed data sets. We performed a piecewise recursive of wind turbines' output energy to measure the EV charging efficiency. Wind averaging results show that the three minutes intervals have increased the total number of EVs by more than 80 due to decoupling of both technologies from the utility grid, energy storage systems, and the associated energy conversion power electronics has merit and research in this direction is worth pursuing
