Among this WBG is the SiC, which is presently one of the dominant power switching devices in renewable energy converters such as photovoltaic and automotive power electronic converters. This paper presents aging tests of SiC MOSFET from CREE subjected to repetitive short-circuit operations. The experimental tests are detailed. The evolution of the electrical static characterizations (drain current Id and gate-source voltage Vgs waves), before and after aging, is presented. Furthermore, the repetitive short-circuit aging effect on electrical parameters (threshold voltage Vth, on-state resistance Rdson and Igss gate and Idss drain leakage currents) is carried out.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":"97 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":"126888675","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 study aims to estimate equivalent circuit parameters of a single-phase transformer using current and voltage values at any known load. The difference between actual and estimated parameter values has been minimized using the MA technique and obtaining the best values for these parameters. The optimum value of the errors between the measured and the estimated values of the primary current, secondary current, and secondary voltage at full load using the proposed MA algorithm was compared with three other algorithms (Particle Swarm Optimization (PSO), Differential Evolution (DE) and Shuffled frog-leaping algorithm (SFLA)).

Biodiesel from waste vegetable oils is a promising alternative to fossil diesel. Several researchers show that increasing biodiesel percentages from 0% to 100% can affect the mixture properties such as density, viscosity, pH, humidity, cetane number, low heating value, etc and it can also reduce HC, CO, and PM emissions while increasing NOx emissions. The main objective of this work is to study the effect of adding percentages of soybean biodiesel in fossil diesel (B5 to B80) on some properties such as density, viscosity and cetane number. The results showed that the studied blends met the standards for considered properties, except for the viscosity at high percentage of biodiesel, also the results showed that mixing biodiesel up to an optimal value of around 45% with Algerian diesel is recommended to ensure the respect of norms for density, viscosity and cetane number.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":"22 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":"133273790","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}

In large-scale electrolysis systems with a high direct current supply, power rectifiers are important components to connect to the main power grid. Currently, Thyristor-based topology is most commonly used for large-scale industrial proton exchange membrane (PEM) water electrolysis applications due to its maturity. However, this topology cannot always satisfy the main grid requirements and instead lead to higher specific energy consumption per kilogram of hydrogen produced. Instead, the transistor-based topology is more promising to reduce the total system cost. In this research, 6-pulse thyristor-based and transistor-based topologies are compared and investigated to improve the power quality for a 20 MW PEM water electrolyzer in Air Liquide's Bécancour plant. We first built a Matlab/Simulink model to simulate the water electrolysis system.

Health care systems have been overwhelmed, already destabilized financial markets further jeopardized, with oil and energy markets plunging into crises and economic activities coming to severe halts. To keep people connected while working from home and upholding life-saving facilities in hospitals and around industrial regimes, reliable affordable electricity is imminent. As an immediate consequence of the pandemic, much pressure has befallen countries with low-energy reserves, where the energy sectors involved had already been staggering and facing major challenges ahead of COVID-19. Jordan’s, being of these impacted countries, peak demand on electricity decreased by 17.5% by early April 2020 compared with the mean 2019 levels. Based on the ARMA and ARIMA models obtained, the impact on 2020 electricity demand in Jordan depends on the durations and levels of the confinement/s, with a low estimate of 2.76% if pre pandemic conditions return by mid-September (2020), and a high estimate of 7% if some restrictions remain in effect worldwide until the end of 2020.

The structure, electromagnetic properties and the phase direction of rotation of the proposed permanent magnet machine were investigated at different phase angle. Background study on the mode structure of establishing the proposed topology of one stator and two rotors instead of the conventional one rotor for the motor operation was done. With attention paid to the losses on the stator and rotor, finite element method was used to establish the structure of the proposed permanent magnet machine. The load simulation of the electromagnetic properties was investigated using FEMM 4.2 and Ansys Maxwell to show the advantages of the proposed machine topology to allowing higher electric loading to increase power density in electric vehicles.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":"33 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":"125386975","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}
