Abstract

Electric vehicles are growing in importance owing to their desirable characteristics leading to utilization. It is a significant challenge to maintain voltage for DC microgrids when integrating with EVs. The work aims to enhance voltage stability in a DC microgrid and the electric vehicle charging using GaN devices in the converter. This is done by developing a DC microgrid with better voltage regulation, loss reduction, and increased efficiency and these are analyzed using PLECS software. Under different operating conditions, the proposed converter can respond to load fluctuations and maintain its voltage profile stable. The approach meets the increasing demand for vehicle charging by upgrading DC microgrid technology. The use of GaN-based converters improves voltage stability while allowing for efficient integration of EVs into the grid thereby giving more options for transportation.

使用模糊控制器的光伏直流微电网双向转换器在电动汽车充电应用中的电压稳定性

由于电动汽车的理想特性，其利用率越来越高。在与电动汽车整合时，如何保持直流微电网的电压是一项重大挑战。这项工作旨在利用变流器中的氮化镓器件提高直流微电网和电动汽车充电的电压稳定性。为此，我们开发了一种具有更好的电压调节、降低损耗和提高效率的直流微电网，并使用 PLECS 软件对其进行了分析。在不同的工作条件下，所提出的转换器能够应对负载波动，并保持电压曲线稳定。该方法通过升级直流微电网技术，满足了日益增长的汽车充电需求。使用基于氮化镓的转换器可提高电压稳定性，同时将电动汽车有效地集成到电网中，从而为交通提供更多选择。

期刊介绍： WSEAS Transactions on Systems and Control publishes original research papers relating to systems theory and automatic control. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with systems theory, dynamical systems, linear and non-linear control, intelligent control, robotics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
