摘要

在各种环境条件下获得最高输出功率的能力是光伏系统应用中最关键的任务之一。尽管已经开发了许多尖端方法来实现这一目标,但大多数方法都有明显的缺点,例如跟踪能力差和计算负荷大。因此,本工作的目的是提出一种控制算法,该算法考虑了太阳能阵列输出功率与MPPT升压转换器控制器的PWM占空比之间的联系。本文提出的自定义CNN在MATLAB/SIMULINK中实现,并与已有的CNN进行了性能比较。研究结果表明,光伏系统在任何天气下发电的能力都有所提高,同时也减少了太阳辐射快速变化对输出功率的影响。

Performance Analysis of MPPT Algorithms Designed for Photovoltaic System
The capacity to reap the highest output power in various environmental conditions is one of the most critical tasks in the application of photovoltaic (PV) systems. Although many cutting-edge methods have been developed to accomplish this, the majority of methods have significant drawbacks, for instance, poor tracking capabilities and heavy computational load. Therefore, the aim of this work is to present a control algorithm that takes into account the connection between the solar array output power and the controller's PWM duty cycle of the MPPT boost converter. The proposed customized CNN is implemented in MATLAB/SIMULINK and compared with well known for its performance. The findings demonstrate an increase in the PV system's ability to generate power in any weather, as well as a reduction in the effects of rapid changes in solar irradiation on output power.
