An Improved Method to Predict the Position of Maximum Power Point During Partial Shading for PV Arrays


For a photovoltaic (PV) system, it's widely assumed that the peaks of a partially shaded P–V curve are located at the multiples of $0.8V_textoc$, where $V_textoc$ is that the open-circuit voltage of the PV module. However, this assumption—known as the of $zero.8V_textoc$ model for partial shading—is not essentially true. If the same model is employed to design the utmost power point tracker (MPPT), it's terribly possible that the algorithm can scan the wrong region of the P–V curve and, hence, an incorrect international peak detection. This paper attempts to prove the inadequacy of the $zero.8V_textoc$ model when the amount of modules within the string increases. Further, the work suggests a straightforward relationship to predict the right position of the peaks. It is found that for a string of twenty modules ($V_textoc$ of four hundred V), the utmost deviation between the actual and computed peak is but 3 V, whereas for the $0.eightV_textoc$ model, the deviation reaches up to fifty V. Additionally, using the proposed technique, the MPPT potency can be improved by approximately two%.
