Abstract

The widespread growth of electric vehicles could pose significant grid and charging infrastructure challenges, especially in areas with underdeveloped infrastructure. This has affected the ease of charging electric vehicles. In this paper, I design a power supply strategy for electric vehicle charging facilities based on wind farm power supply. In this strategy, a preliminary selection of line conductors is carried out, and several schemes are preliminarily determined. Further comparative analysis is made from the three aspects of conductor, tower type, and bus. Through the PowerWorld software, a simulation model is established for each scheme, and an optimal strategy that takes into account economy, security, and system stability is obtained (AAC 31.5 mm double split, tower A and bus 5). This can assist in the transformation of electric vehicle power supply and the construction of wind farm power supply facilities.

Highlights

Energy is the cornerstone of the development of the automobile industry, and energy affects the degree of development of the automobile industry [1]
New energy [2] is gradually becoming the backbone of future electric vehicle development [3]
If the arrangement of three-phase conductors of different towers is inconsistent, the same conductors are erected on different towers, the calculation methods of mutual geometric mean distance (GMD) of transmission lines are different, and the line reactance and line susceptance are different

Summary

Introduction

Energy is the cornerstone of the development of the automobile industry, and energy affects the degree of development of the automobile industry [1]. Even in a modern society with the development of science and technology, the world’s energy source is conventional energy. New energy [2] is gradually becoming the backbone of future electric vehicle development [3]. New energy technology will be a key factor affecting people’s work and lives in the future. With the gradual exhaustion of fossil energy [4] and the aggravation of pollution, people begin to pay attention to the utilization of renewable resources, such as wind energy and light energy and develop a wind–wind complementary power generation system. The proportion of wind power in the world’s energy structure has been increasing year by year, and it is the fastest way to increase the proportion of renewable energy [6], creating great economic value and environmental value
