光伏系统最大功率点追踪算法研究综述

A review of maximum power point tracking algorithmsfor photovoltaic systems

目前,能源危机日益严重,为了提高光伏系统的输出功率,保证在不同环境下始终能输出最大功率,需要对光伏电池最大功率点进行追踪。文中在分析最大功率点追踪的基本原理基础上,介绍了目前常用的最大功率点追踪方法,重点分析了单峰值和多峰值条件下最大功率点追踪算法,并对今后最大功率点追踪的发展趋势进行了展望。

With the increasingly serious energy crisis,in order to improve the output power of photovoltaic system and ensure the maximum output power in different environments,it is necessary to track the maximum power point of photovoltaic cells.Based on analysis of the basic principle of the maximum power point tracking(MPPT),the maximum power point tracking algorithm under single peak and multi-peak conditions was introduced,respectively,and the development trend of maximum power point tracking in the future was forcecasted.
