中文摘要

摘要 部分阴影显著降低了光伏系统的性能,导致热点和失配损耗。为减轻部分阴影对光伏系统造成的不利影响,一种有效的解决方案是采用光伏阵列重构技术。本文全面综述了针对部分阴影问题所设计的光伏阵列重构技术的最新研究进展。所选取的重构技术被系统地讨论并分为两大类:静态重构和动态重构,这两类进一步细分为九个不同的子类别。除了对这些技术进行详细描述外,本文还基于阵列规模、算法复杂度、响应速度、性能优越的方法、优势、劣势、实施成本以及应用范围等多个维度进行了比较分析,以帮助研究人员和工程师为其特定应用场景选择最合适的重构技术。此外,本研究还探讨了实际实施过程中面临的技术挑战,并提出了未来研究方向的建议。

English Abstract

Abstract Partial shading significantly reduces the performance of Photovoltaic systems , leading to hotspots and mismatch losses. One effective approach to minimize the negative impact of partial shading in PV systems is the PV array reconfiguration technique. This paper presents a comprehensive review of the state-of-the-art developments in PV array reconfiguration techniques designed to address the problem of partial shading. The selected reconfiguration techniques are thoroughly discussed and categorized into two groups: Static and Dynamic, which are further divided into nine distinct subcategories. In addition to providing a detailed description of these techniques, a comparison is performed based on array size, algorithm complexity, response speed, outperforming methods, advantages, disadvantages, implementation cost, and applications range to help researchers and engineers choose the most suitable reconfiguration techniques for their specific applications. The study also discussed the implementation challenges and provided recommendations for further research direction.
