Abstract
A simulation model is established to track the maximum power point of solar array in Matlab/ Simulink,which can verify the effectiveness of different algorithms. Using the method of Perturbation and Observation(P&O) and Incremental Conductance(INC) track the maximum power point of a solar-array under different illumination intensity and panel temperature. Analyzed the influence of disturbance step length for tracking precision or response time and the influence of A/D sampling frequency for the tracking stability. Proposed a method to select appropriate disturbance step length and sampling frequency according to the scale of photovoltaic array.
