摘要
详细介绍了一种基于 MPPT 的光伏发电系统,并对光伏电池功率电压曲线进行了详细分析,根据分析结果把模糊 PID 控制应用到光伏发电系统最大功率点跟踪的控制当中,模糊 PID 控制能快速响应外界环境的变化,使光伏系统始终工作在最大功率点,提高系统的稳定性。
This paper introduced in detail one kind of photovoltaic power system base on maximum power point tracking. According to the asymmetric characteristics of photovoltaic array,a novel fuzzy PID control method is introduced for MPPT of photovoltaie generation system. Photovoltaic energy generation system can track the maximum power of PV cell rapidly and improve the stability of the system by using fuzzy PID control.
