Several researchers suggested different alternatives for concentrated solar thermal and power systems. Among the various PTC alternatives, Semi-Parabolic Linear Fresnel Reflector (SPLFR) is considered a promising design to tackle the issue of manufacturing float glass mirrors in developing countries. In this study, an optical investigation was performed for different parameters of the SPLFR. With fixed strip mirrors widths of 45 mm, the heat flux was less affected by optical errors for a rim angle of 100°. Coupling errors have resulted in a compensation effect from which it was deduced that a control for non-random errors should be carried out for a better flux distribution. A displacement error of 6.2 mm with an offset angle of 45° has enhanced the optical efficiency for collecting rays diverged by the tracking error, thus an efficiency of 79% could be reached. This study also shows preliminary experimental results of a locally constructed SPLFR system.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":"260 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133619405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125349147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, automotive manufacturers and equipment suppliers are moving towards hybrid vehicles. This change is leading electronics designers to use Gallium Nitride (GaN) technology within power modules. The use of this new technology may call into question the reliability of the system, which is directly related to the device aging. Among factors that can influence component aging is temperature. This paper describes the internal structure of a chosen device which is presented in LGA (Land Grid Array) package in order to create a thermal model through a finite element study that aims at extracting an electrothermal model describing the real component behavior within power module.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122805574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce the TCE of the system which contains a PV/Wind sub-system and a battery, the conventional Genetic Algorithm (GA) based approach is used. The continuity of service requires the substitution of the production source overnight by the association of a lead-acid battery under the global system in order to control the output power by meeting the needs of consumers. By introducing the TCE as important factor, an economic evaluation is elaborated by presenting an acceptable cost of energy.
