摘要
针对传统太阳能最大功率点跟踪算法效率较低的缺点,在原有经典定电压跟踪方法的基础上,提出了基于扰动观察法和梯度法的双重寻优最大功率点跟踪算法。采用Matlab/Simulink工具对单相光伏逆变并网系统进行仿真。仿真试验结果表明,该算法能更稳定、更高效地对太阳能最大功率点进行跟踪,并能保持系统稳定和跟踪精度,具有很好的动态性能。
Aiming at the shortcomings of traditional tracking method of the maximum power point of solar energy, and on the basis of classic rated voltage tracking method, the dual optimization tracking algorithm based on disturbance observation method and gradient method is proposed. The single-phase photovoltaic inverter grid system is emulated by adopting Matlab/Simulink simulation tools. The experimental simulation results show that the algorithm is able to track the maximum power point of solar energy more effectively and more stably, and ensure the stability of system and the tracking accuracy, and possesses excellent dynamic performance.
