摘要

与内燃机汽车(ICE)相比,电动汽车(EV)的大量使用克服了全球变暖对环境造成的快速增长的影响。在运输业中,这些车辆的替代降低了运行成本、生态排放和车辆维护费用。电动汽车通过可用的电池能量运行,并通过公用事业电网集成的电动汽车充电站供电。值得注意的是,由于电动汽车充电站中存在电力电子转换设备,这种充电站可能会带来电能质量问题,对电网产生很大影响。采用有源通用电能质量调节器(AUPQC)装置可消除电能质量对配电网的主要影响。AUPQC 的主要作用是通过可行的控制目标来缓解电网侧和充电站的各种电能质量问题。本研究提出了一种新的广义电压-电流参考(GVCR)控制目标,用于提取基本参考电压-电流信号。其主要发现是数学符号简单、无需变换、响应速度快、低 dv/dt 开关应力、低开关损耗和最高效率。主要目标是通过 MATLAB/Simulink 计算工具,在将各种电动汽车充电器集成到电网的情况下,验证所提出的 GVCR 控制 AUPQC 设备的设计、运行和性能,并提供仿真结果以供分析和解释。

PQ enhancement in grid connected EV charging station using novel GVCR control algorithm for AUPQC device
The rapid increase of environmental impacts together global warming is conquered by substantial selection of electric-vehicles (EV’s) over the internal-combustion engine (ICE) vehicles. The replacement of these vehicles in transportation industry has led to reducing the running cost, ecological emissions, vehicle maintenance. The EV’s are operated by available battery energy and energized through utility-grid integrated EV charging stations. It is noted that, such charging stations may introduce power-quality issues, highly impacting the electric-grid due to presence of power electronic conversion devices in EV charging stations. The primary emphasis of power-quality impacts on electrical distribution grid are counteracted by employing active universal power-quality conditioner (AUPQC) device. The main role of AUPQC has been selected for mitigation of various PQ problems on both electric-grid side and charging station by using feasible control objective. In this work, a novel generalized voltage-current reference (GVCR) control objective has been proposed for extraction of fundamental reference voltage-current signals. The key findings are simple mathematical notations, no transformations, fast response, low dv/dt switch stress, low switching loss and maximum efficiency. The main goal is design, operation and performance of proposed GVCR controlled AUPQC device has been validated under integration of various EV chargers to electric-grid by using MATLAB/Simulink computing tool, simulation results are presented for analysis and interpretation.
