摘要

通过对太阳能电池串联电路的动态特性分析，建立了不均匀光照条件下多峰值出现的充要条件.基于串联电路的工作原理，建立了局部峰值点功率之间的数学关系，确定了最大功率点区间位置的动态判断系数.该方法可快速定位全局最大功率点所在区间，确定该区间的上下边界，将电导增量法的运行初值保持在该区间，能够使其快速准确跟踪到全局最大功率点.该方法利用较少计算和小区间搜索代替全局搜索，具有良好的快速性和准确性.同时该方法改善了区间搜索重启条件使其拥有较强的鲁棒性.

Abstract

Based on circuit analysis, this paper shows that the number of peak points can be determined by short-circuit currents and maximum-power point currents of all the arrays in series. The principle is established based on which the number of the peak points is to be determined. Furthermore, based on the dynamic characteristic of solar array, this paper establishes the rule for determination of the relative position of the global maximum power point. In order to track the global maximum power point within an appropriate period, a reliable technique and the corresponding computer algorithm are developed for global maximum power point tracking control. It exploits a definable nonlinear relation is found between variable environmental parameters and the output current of solar arrays at every maximum power point, obtained based on the dynamic performance corresponding to partial shading conditon.
