摘　　要：为解决太阳电池组件模型精度和参数获取之间的矛盾,提出一种基于Lambert W函数的太阳电池组件参数确定及优化算法。利用Lambert W函数推导出太阳电池组件各参量的解析式,并结合太阳电池组件电压功率模型的最大功率点优化算法提高参量精度。实验表明,该方法不仅可精确获取太阳电池组件各参数值,且可使最大功率点的精度提高到1%以内。In order to solve the contradiction of model accuracy and parameters extraction for PV module, a new method based on Lambert W function was proposed, which could determine and optimize parameters. The analytical formula of each parameter was derived by using Lambert W function, and combining with optimization algorithm of maximum power point for voltage power model, the precision of parameters could be improved. Experiments show that this method not only can obtain parameters of PV module exactly but also can make the accuracy of the maximum power point up to the range of 1%.
