Real-Time Experimental Assessment of a New MPPT Algorithm Based on the Direct Detection of the Short-Circuit Current for a PV System

To substantially increase the efficiency of photovoltaic (PV) systems, it is important that Maximum Power Point Tracking (MPPT) system has an output close to 100%.This process handled by MPPT algorithms such as Fractional Open-Circuit Voltage (FOCV), Perturb and Observe (P&O), Short-Circuit Current (FSCC), Incremental Conductance (INC), Fuzzy Logic Controller (FLC) Neural Network (NN) controllers. The FSCC algorithm simple be implemented uses only one current sensor. This method based on unique existence linear approximation between (MPP) short-circuit in standard conditions. speed this optimization technic fast, however needs PV panel each time order obtain short circuit current. leads energy losses high oscillations. In improve algorithm, we propose a direct detection shortcircuit simply reading panel. value allows directly calculating incrementing or decrementing solar irradiation. Experimental results show response attenuation, little oscillations, power reduction better accuracy enhanced compared conventional method.
