Abstract

The present paper presents specific issues that arise in Photovoltaic Energy Conversion Systems, being focused on maximizing the output power. There is proposed a model for Photovoltaic PV panel external characteristics. The coordinates of maximum power point are determined and used for imposing the appropriate load resistance to maximize the provided power. A comparison is made considering the classical control methods and the proposed optimized method, that prove better performances than methods based on output power measurement.

光伏能量转换系统建模与优化控制
本文介绍了光伏能源转换系统中出现的具体问题,重点是最大限度地提高输出功率。提出了光伏板外部特性模型。确定最大功率点的坐标,并用于施加适当的负载电阻,以最大限度地提供功率。将经典控制方法与本文提出的优化方法进行了比较,结果表明该方法比基于输出功率测量的方法具有更好的控制性能。
