Abstract
Much research is directed to evaluate the performance of renewable energies such as photovoltaic (PV) and wind due to their significant impact on the reliability of the power system. This paper presents the reliability assessment of the solar PV system by concentrating on the probabilistic of the variability power PV connected to components of dc converter circuits. Three different types of dc chopper (Boost, Buck-Boost, and cuk) are analyzed based on each converter component's failure rate and the mean time between failures. PV integration with a dc converter improves the probabilities of various levels of PV; therefore, system adequacy indices such as reference yield and loss of load expectation are evaluated to evidence the system reliability performance. A comparison of the dc converters and loss indexes is made using the MATLAB environment. The outcome of shows more stability and reliability with the Cuk dc converter.
