摘要
提出一种依据功率变化大小的变步长扰动观察法,应用于光伏系统的最大功率跟踪(MPPT),并在实现MPPT算法的过程中融入系统不同工作模式下的降额处理方法,并通过仿真验证了此算法的正确性。
An observation method of power changes based on the size of the variable step size perturbation and method is proposed and applied in Maximum Power Point Tracking （MPPT） of PV systems. The derating processing methods of MPPT algorithm integrated into system under different operating modes and correctness of this algorithm is verified by simulation.
