Sustainability | Free Full-Text | A Novel Hybrid Approach for Maximizing the Extracted Photovoltaic Power under Complex Partial Shading Conditions


The handy design of a most energy level monitoring (MPPT) controller is vital to the success of photovoltaic (PV) system efficiency with a view to maximize the extracted energy, which is affected considerably by climate fluctuations, notably partial shading situation (PSC). This paper proposes a novel hybrid MPPT method based mostly on a modified Perturb and Observe (P&O) assisted by the Extremum In search of Management (ESC) technique, combining the advantages of those easy algorithms and, in the meantime, eliminating their drawbacks. The proposed algorithm is ready to monitor the utmost doable energy beneath any stage of climate fluctuation, with complete enhancement on all features of excessive efficiency, boosting the PV array effectivity to 100%, decreasing the convergence time to lower than 100 ms, utterly eradicating the oscillations across the achieved energy, and sustaining the simplicity ranges of each concerned methods. Extra importantly, this algorithm is relevant for any PV array configuration, which boosts the robustness and novelty of the algorithm. The efficiency is verified utilizing MATLAB/Simulink. A lift converter is used for controlling DC to DC (direct present to direct present) energy. The proposed algorithm’s efficiency is in contrast with the standard P&O and incremental conductance (IC) algorithms beneath 4 completely different instances of climate situations. The shortcomings of those algorithms are illustrated and the evaluation confirms the effectiveness of the proposed algorithm accordingly.
