    Futoshiki technique for PV array power optimization Under partial shading conditions
    (University of M'sila, 2023-07-16) ZIANI, Z IANE; BELKAIBECH, YOUNES; Enca/ Djamel, SAIGAA
    The energy generated from photovoltaic generators is somewhat low compared to others, and its efficiency is low due to the fluctuation of the amount of energy produced related to weather conditions (temperature, irradiation level...), and therefore it must be improved. In this work, we conduct a study in the proposed configurations (SP BL HC TCT) in order to improve the power of the photoelectric generator is not uniformly illuminated, the work that we have done after that is the optimization of the TCT configurations by futoshiki technique used in order to disperse the shading effect. By simulating partial shading scenarios for a photovoltaic generator and comparing the results before and after reconfiguration, the effectiveness of this strategy was confirmed.

    Photovoltaic Generator power Enhacement Competence using square technique
    (university of M'sila, 2022-09-25) TOUMI, Sarra; MAHMOUDI, Fatima ezzahra; Enca/ Djamel, SAIGAA
    Recently, the increasing interest in solar energy has led to the development of large scale solar arrays. Although the most commonly used TCT (total cross-connection) interconnection scheme minimizes mismatch losses. However, the shading in large PV arrays can significantly reduce the power output and cause multiple power peaks in the P-V characteristics. In order to avoid the problem of multiple peaks, PV arrays are reconfigured using electrical or physical reconfiguration techniques. For this purpose, the physical repositioning method proved to be effective and economical in achieving better shadow dispersion, as it neither requires complex switch arrangements or expensive controllers for reconfiguration compared to electrical methods. Therefore, this graduation thesis introduces an innovative Competence Square (CS) technology for the physical rearrangement of photovoltaic panels in a TCT interconnection scheme.
