    Contribution to The Reliability Study of Photovoltaic Systems Using Static and Dynamic Analysis Methods
    (Inderscience, 2019) Mahdi, Ismahan; Nadji, Bouchra; Simeu-Abazi, Zineb
    The study of reliability has not been received great attention from researchers, an estimation of a lifetime and why not improve enhance is still possible. For that, it is necessary to distinguish the different failure modes, their causes and their effects on solar modules, in our case composed by Silicon, the most spread technology and the most used in the production of electricity. In this article, we will present a contribution to the reliability study of photovoltaic systems. First, the study will be focused on the static analysis of our system by using: structured analysis and design technique and function analysis system technique methods, which make it possible to carry out a functional analysis of our system. Next, our study will be based on the dynamic analysis by using: failure mode, effects, and criticality analysis, fault tree analysis and finally stochastic Petri nets methods. These allow making a dysfunctional analysis of the system by introducing the ‘time’ which is a very important factor in our study

    Reliability study of a system dedicated to renewable energies by using stochastic petri nets : application to photovoltaic (PV) system
    (Elsevier, 2017) Mahdi, Ismahan; Chalah, Samira; Nadji, Bouchra
    Access to energy is essential to reduce poverty. Globally, around 1.2 billion people, about 16% of the global population, still do not have access to electricity. Knowing that photovoltaic (PV) energy already lengthily showed its evidence in terms of operation and reliability, its development observed an improvement of technologies in terms of solar energy transformation output by the semiconductor, and the research in this field does not cease to progress. However, reliability and availability study of PV systems have not been received great attention from researchers, for that we decided to give it a consideration in our research works. So, we seek to study the reliability of such system by using functional and dysfunctional analysis methods. In this paper, we will be interested in the two parts of PV system: “PV module” composed by Silicon cells, and “the converter” which is the expensive component and the most complex in a PV system
