For a photovoltaic (PV) system, it is widely assumed that the peaks of a partially shaded P-V curve are located at the multiples of 0.8V oc , where V oc is the open-circuit voltage of the PV module. However, this assumption - known as the of 0.8V oc... Read More about An improved method to predict the position of maximum power point during partial shading for PV arrays.

This paper proposes a method to improve the efficiency of the P&O maximum power point tracker (MPPT) by reducing the steady state oscillation and eliminating the possibility of the algorithm to lose its tracking direction. A dynamic perturbation step... Read More about An improved perturb and observe (P&O) maximum power point tracking (MPPT) algorithm for higher efficiency.
