摘要
分析并建立了光伏阵列的数学模型,得出在不同光照强度和温度下光伏阵列的P-V特性曲线,针对光伏发电最大功率点跟踪传统方法,提出将模糊控制加入到扰动观察法中,在Matlab中通过仿真对比分析改进前后扰动观察法的输出功率曲线,证明加入模糊控制后的扰动观察法在跟踪的速度和稳定性上都有所提高。
The mathematical model of the PV array is analyzed and established,and the P-V characteristic curve of the PV array under different illumination intensity and temperature is obtained.Traditional method for tracking maximum power point of photovoltaic power generation is considered and the improved perturbation observation method is simulated comparison in Matlab.It prove that the disturbance observation method after adding fuzzy control improves the tracking speed and stability.
