Abstract :
The tracking of maximum power produced by photovoltaic (PV) system is very important to increase the efficiency of solar energy utilization. This can be achieved using maximum power point tracking (MPPT) system based on power electronics converter that adjusts the electrical operating point of the PV module to output the maximum available power. In this work, MPPT control technique has been introduced with fast and accurate tracking speed. Perturb and observe (P&O) MPPT algorithm was simulated using Simulink, and experimentally implemented using micro-controller. The proposed technique was validated by examining simulation and practical results of the implemented setup. Experimental results showed good agreement with simulation results.
