    The degradation of the electrical performance of photovoltaic panels UDTS 50W exposed to the sun for a long period of about 10 years in a Saharan environment of Adrar was presented. In this article, we will present some experimental results obtained during the analysis of the I-V characteristics of some UDTS 50W photovoltaic panels tested in the real conditions of the Saharan environment (Adrar region). The degradation of the electrical performance of the UDTS-50 W module is visualized through the analysis of the I-V and P-V characteristics experimentally or by visual field inspection of a renewable energy research unit in a Saharan environment. The physical parameters of the equation governing these characteristics were determined by the effective iteration method using only the information in the data sheet. The comparison between the experimental characteristic curves IV and PV of the PV modules (UDTS 50) and the reference in STC shows that the degradation of the electrical performances are due globally by the delamination and the discoloration of the EVA encapsulate after the long term exposure in a desert environment

    RST controlled DFIG based wind energy conversion systems
    (university Of Eloued جامعة الوادي, 2020-02-23) ARAMA Fatima Zohra; LARIBI Slimane; HAMOUDA Messaoud
    This work presents a field oriented control (FOC) of active and reactive power applied on Doubly Fed Induction Machine (DFIM) 1.5MW integrated in wind energy conversion system (WECS). The main objective of this work is to compare the performances of energy produced by the use of two types of controllers ( PI regulator and the RST regulator) in order to control the wind power conversion system to compare their precision & robustness against the wind fluctuation and the impact on the quality of produced energy. A field oriented control of DFIG stator is also presented to control the active and reactive power. To show the efficiency of the performances and the robustness of the two control methods those were analyzed and compared by simulation using Matlab/Simulink software. The results described the favoured method
