| Abstract: | In order to track the maximum power point effectively in photovohaic systems, this paper sets up the simulation model of the PV module based on MATLAB/Simulink software and analyzes the non - linear output characteristics of the PV module according to its U - I, P - I and P - U characteristic curves. The variable step disturbance observation method, based on the dynamic characteristics of the PV module, is used to track the maximum power point. Simulation results indicate that this module can rapidly and stably track the maximum power point much better than the traditional methods. |
