摘要: 本文基于SGD-CMA算法对光伏发电系统中MPPT控制，并针对SGD-CMA算法收敛速度的缺点提出了基于小波算法的光伏发电系统MPPT控制设计方案。本文搭建了光伏电池的仿真模型模拟分析了光伏阵列在温度、光照变化情况下的功率输出特性，仿真结果显示改进后的扰动观测法会获得更稳定的电压和功率输出，系统的可靠性增加。
Abstract: In this paper, the SGD-CMA algorithm is proposed in MPPT control for the photovoltaic power generation systems. However, the convergence rate of SGD-CMA algorithm is slow. To solve this problem, wavelet SGD-CMA algorithm is proposed. A simulation model for the photovoltaic cell is set up to analyze the PV curve under the different condition of temperature, and illumination. The simulation results have shown that the improved algorithm can get more stable output power, and the reliability of the system is increased.
