Photovoltaic (PV) arrays are power generation equipment in PV systems. Maximum power point Tracking (MPPT) scheme in the PV array affects the power generation efficiency of the PV system. In this paper, based on the deficiencies of existing MPPT methods, an algorithm by combining the increment conductance method with variable step size and Newton interpolation method is proposed, which can automatically adjust the step size according to changes in the external environment to avoid power loss and improve the photovoltaic power generation efficiency. The results show the improved MPPT algorithm can efficiently control the vibration amplitude of the power waveform output compared with the traditional conductance increment method. The problem studied in this paper is somewhat interesting. I have the following comments. Meanwhile, it presents a faster tracking speed and a good adaptability for the environment.
