摘要
在太阳能光伏发电中,实现高效的最大功率输出是重要的研究方向。本文主要对恒压跟踪法进行优化,在光伏发电板温度变化时,使恒压跟踪能相对精确地随温度实现变压跟踪,通过在PSIM上建立仿真模型进行分析验证。该方法具有较好的功率输出,控制及实现起来简单,所以它在具体的光伏发电工程中有很高的实用性。
In solar photovoltaic power generation,achieving high-efficiency maximum power output is an important re⁃search direction.This paper mainly optimized the constant voltage tracking method,which enabled constant voltage tracking to achieve variable voltage tracking with temperature relatively accurately when the temperature of the photovoltaic power genera⁃tion panel changed,the simulation model was established on PSIM for analysis and verification.This method has good power output and is simple to control and implement,so it has high practicability in specific photovoltaic power generation projects.
