| 摘 要： | 为了寻找更好的实现光伏发电系统最大功率点跟踪控制方法,基于单个光伏电池的物理特性建立了太阳能光伏电池阵列的Matlab仿真模型,分析了太阳能光伏电池阵列所具有的随着光照强度和温度不同而变化的P-U和I-U非线性特性.基于光伏电池的动态特性,在最大功率点跟踪算法的设计中增加一个电流监测回路,并结合自寻优技术对电导增量法进行改进,提出了一种自适应变步长寻优算法.仿真结果表明,该算法能够快速准确的跟踪最大功率点.

| Abstract: | Photovoltaic array simulation can be used to find better methods to implement maximum power point tracking (MPPT) control for efficient solar power systems. An accurate and practical model for photovoltaic arrays is developed with Matlab for the photovoltaic cell mechanisms. The model could simulate both the P-U and I-U characteristics of photovoltaic arrays for any insolation level and ambient temperature. Test results prove that the improved variable step optimization algorithm with current monitor circui... |
