摘要

光伏系统容易受到遮挡及不均匀环境条件的影响，旁路二极管的引入可以防止光伏组件中过热点的发生，但会在光伏阵列功率-电压特性曲线中产生大量峰值。此时运用传统的最大功率点跟踪方法可能会让系统工作在某一个局部峰值附近，而无法确保工作在最大峰值上。群优化方法可以解决这一问题，但其收敛时间过长。灰狼优化算法是一种快速且更可靠的优化算法，适用于在不同局部阴影遮挡下光伏系统的最大功率点跟踪。传统的灰狼优化算法涉及较长的转换时间、较大的稳态振荡和高故障率。本工作通过将布谷鸟搜索与灰狼优化算法相结合来解决这些问题，以提高最大功率点跟踪性能。并将该方法与传统的灰狼优化算法和基于扰动观测的最大功率点跟踪方法进行了比较。对比分析表明，在非均匀运行条件下，本文提出的灰狼优化-布谷鸟搜索混合算法优于其他两种方法。

Abstract

Photovoltaic (PV) systems are adversely affected by partial shading and non-uniform conditions. Meanwhile, the addition of a bypass shunt diode to each PV module prevents hotspots. It also produces numerous peaks in the PV array’s power-voltage characteristics, thereby trapping conventional maximum power point tracking (MPPT) methods in local peaks. Swarm optimization approaches can be used to address this issue. However, these strategies have an unreasonably long convergence time. The Grey Wolf Optimizer (GWO) is a fast and more dependable optimization algorithm. This renders it a good option for MPPT of PV systems operating in varying partial shading. The conventional GWO method involves a long conversion time, large steady-state oscillations, and a high failure rate. This work attempts to address these issues by combining Cuckoo Search (CS) with the GWO algorithm to improve the MPPT performance. The results of this approach are compared with those of conventional MPPT according to GWO and MPPT methods based on perturb and observe (P&O). A comparative analysis reveals that under non-uniform operating conditions, the hybrid GWO CS (GWOCS) approach presented in this article outperforms the GWO and P&O approaches.
