中文摘要
三维曲面光伏(PV)模块可在建筑立面、车辆和可穿戴设备等不规则表面上实现灵活集成,但在非均匀辐照和电流失配条件下会面临严重的功率损失。本研究提出一种改进的模拟退火算法(ISAA),用于6×6曲面光伏模块的实时电气拓扑重构。该ISAA重构方法将面级辐照度反馈嵌入退火搜索过程,将全局最优电流失配指数引入其接受准则以克服局部最优问题,并执行并行、无参数的电池交换试验以实现快速收敛。本文在多种光照分布条件下对比了ISAA、TCT和SDS三种重构方法的性能,并评估了其在动态辐照环境中的适应能力。结果表明,ISAA在所有情况下均能将电流失配指数维持在1以下,平滑I–V/P–V特性曲线。此外,ISAA有效降低了电流失配的累积效应,在晴天和阴天条件下均能保持相对稳定的性能提升。与TCT和SDS相比,ISAA可将日均失配损失减少高达52%,日均能量输出提高42%~44%,并在快速变化的辐照条件下提升了填充因子和运行稳定性。总体而言,ISAA能够应对复杂的辐照分布、动态阴影以及天气波动,从而实现三维光伏系统性能的优化。
English Abstract
Abstract Three-dimensional curved photovoltaic (PV) modules offer flexible integration on irregular surfaces such as building facades , vehicles, and wearable devices , but it faces severe power losses from non-uniform irradiance and current mismatch. This study develops an Improved Simulated Annealing Algorithm (ISAA) for real-time electrical topology reconfiguration of a 6 × 6 curved PV module. The ISAA reconfiguration method embeds facet-level irradiance feedback into the annealing search, integrates a global-best current-mismatch index into its acceptance criterion to overcome local optima, and executes parallel, parameter-free cell-swap trials for rapid convergence. This paper compares the performance of ISAA, TCT, and SDS reconfiguration methods under various illumination distribution conditions and evaluates the adaptability under dynamic irradiance environments. Results show ISAA maintains a current mismatch index below one in all cases, smooths I–V/P–V characteristics. In addition, ISAA effectively reduces the cumulative effect of current mismatch and maintains relatively stable performance improvement under both sunny and cloudy weather conditions. ISAA reduces daily mismatch losses by up to 52 %, boosts daily energy yield by 42 % ∼ 44 % compared to TCT and SDS, and enhances fill factor and operational stability under rapidly changing irradiance. Overall, ISAA handles complex irradiance, dynamic shading, and weather fluctuations, enabling optimized 3D PV performance .
