Abstract

This paper investigates the impact of the charging level of high penetration level of Electric Vehicles (EVs) on the power quality of the electricity distribution network. The EV owners tend to charge their EVs as fast as possible. The charging levels of EVs within the distribution network affect the voltage profile of buses of the network. In this paper, an exact Second-Order Cone Programming (SOCP) formulation of the full AC optimal power flow (ACOPF) problem of the distribution network is presented. The network includes solar generation units and EVs as Distributed Energy Resources (DERs). Different charging levels are considered to analyze the impact of EVs on the distribution network. The performance of the proposed model is illustrated for the modified IEEE-33 bus system for different charging levels for EVs. Besides, the impact of available solar power and battery degradation cost of EVs on the distribution network is investigated. It is illustrated that how EV charging will cause voltage deviation challenges for the distribution network.

配电网内电动汽车高充电率对电能质量的影响分析

本文研究了高渗透率电动汽车充电水平对配电网电能质量的影响。电动汽车车主倾向于尽可能快地给电动汽车充电。配电网内电动汽车的充电水平影响配电网母线的电压分布。本文给出了配电网全交流最优潮流问题的精确二阶锥规划(SOCP)公式。该网络包括太阳能发电机组和电动汽车作为分布式能源(DERs)。考虑不同的充电水平，分析电动汽车对配电网的影响。以改进的IEEE-33总线系统为例，说明了该模型在不同充电水平下的性能。此外，还研究了太阳能可用电量和电动汽车电池退化成本对配电网的影响。说明了电动汽车充电对配电网电压偏差的挑战。
