Subject to the energy shortage and environmental pollution and based on the traditional photovoltaic cell mathematical model, a simple and accurate photovoltaic cell model was established in Matlab/Simulink environment. It can be seen from the input/output curve that this model can perfectly reflect the input/output characteristics of photovoltaic cells. The disturbance algorithm and the fuzzy algorithm are combined into the model to establish the MPPT simulation system of the photovoltaic cell. The simulation results show that the system can track the Maximum Power Point (MPP) in the current environment.
