Abstract

Maximum power point tracking (MPPT) technique with improved current feedback has been proposed for solar photo-voltaic system in this work. A proportional integral derivative (PID) type controller with online set-point adjustment has been designed. The parameters of PID controller have been tuned using relay tuning method. Performance of this technique has been compared with perturb and observe (P & O) method of maximum power point tracking (MPPT). Matlab/Simulink model of solar photo-voltaic system and boost converter with proposed maximum power point tracking (MPPT) technique and perturb and observe maximum power point tracking (MPPT) technique has been designed. Simulation results showed the superiority of proposed method for tracking maximum power point (MPP) under rapidly varying solar radiations as compared to P & O maximum power point tracking (MPPT) technique.
