摘要
根据光伏太阳电池板的内部结构和输出伏安特性建立光伏方阵的Matlab仿真模型,利用实测的气象光强数据对恒压跟踪法、爬山法、爬山改进法和INC法等4种光伏系统最大功率跟踪(MPPT)控制算法进行计算机仿真,评价每种算法在不同天气的光照变化条件下特别是光照强度迅速变化时的跟踪效果,得出各个算法的优缺点。仿真结果用于指导太阳能光伏系统最大功率跟踪器的设计及其控制算法的选择。
The Matlab model of the Photovohaic array was set up based on the fabric andⅠ-Ⅴoutput characteristic of PV module. The model was used to simulate the maximum power point tracking（MPPT） of Photovoltaic System by using different MPPT control algorithms, including the CVT, the P＆O, the improvement-P＆O, the INC etc. according to actual irradiance data in different weather condition to evaluate and compare the efficiency of each MPFr control algorithm in different insolation condition , especially the quick changing irradiance one. The simulation result will be used to guid the design of MPPT controller and the choice of MPPT control algorithms.
