MPPT Design of Photovoltaic Power Generation System Based on Improved Fibonacci Linear Search Algorithm

At present, photovoltaic power generation is becoming increasingly popular, and one of its major drawbacks is the low photoelectric conversion efficiency of photovoltaic cells. In order to improve power generation efficiency, an equivalent circuit model of photovoltaic cells and a simulation structure of photovoltaic power generation systems have been established. The working principle and MPPT (Maximum Power Point Tracking) control process of the improved Fibonacci linear search algorithm have been analyzed to achieve the goal of improving power generation efficiency. The improved Fibonacci linear search algorithm is applied in the MPPT technology of photovoltaic power generation system, and simulation experiments are conducted. Through analysis and simulation, MPPT can quickly track the maximum power point when the external lighting conditions change and has good tracking effect.
