摘要(Abstract)：

针对现有光伏最大功率点跟踪MPPT(maximum power point tracking)技术在功率多峰值情况下的不足,提出一种基于电压-功率扫描的多峰快速MPPT方法。首先通过仿真分析了光伏陈列在局部阴影状态下的输出特性;然后提出通过对光伏输出端并联电容的电压-功率扫描实现现况下全局最大功率点识别的总体思路;紧接着给出了实现端口电压扫描的主电路拓扑,并对其进行了状态分析和控制算法设计;最后对所提方案进行了Matlab仿真与样机试验验证。结果表明,该方案能稳定、快速、有效地实现对当前全局最大功率点的追踪与锁定。

关键词(KeyWords)： 电压-功率扫描;光伏;功率多峰值;最大功率点跟踪技术
