However, renewable energy systems are facing two major difficulties: storing electrical power when consumption is quite below the production potential, and delivering electricity when high consumption peaks appear. This paper aimed to simulate an alternative process that can store and restore renewable electricity by forming and reforming the natural gas (methane). The specificity of this process is sharply interesting, since it uses methane as a means of storage instead of electricity, taking advantage of the high energy density of methane. The gas transformation will be coupled to a reversible solid oxide cells (RSOC) working at high temperature (1073 K). The simulation results showed that the installation can deliver electricity with 36.4% of energy efficiency, while electricity storage is performed with an efficiency of 92.4%. The best advantage lies on the process carbon balance: storing then restoring 1 MWh of electricity will only emits 69 g of additional CO2 in the air.","PeriodicalId":130577,"journal":{"name":"2013 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128751666","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 the following research a computational fluid dynamics study is performed to model the gasification of discrete coal particles stream using air as oxidizer. The main objective of the study is to understand the effect of the oxidizer's velocity on the conversion of coal particle and syngas composition. Initially the chemical composition of coal particle is measured using the proximate, ultimate and calorimetric analysis. The measured results are used to define the coal properties in the numerical simulation. Afterwards, a parametric study for inlet velocity of oxidizer is performed. The result shows that at lower velocities complete conversion of coal can be attained but at the same time the quality of syngas is degraded due to the formation of CO2 and H2O. On the other hand the increase in velocity tend to reduce the conversion of coal particle due to decrease in residence time in the gasifier. Further result of CO and H2 mole fraction, temperature and velocity contours are also presented.","PeriodicalId":130577,"journal":{"name":"2013 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129760097","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}

Since the former method replenishes material resources, it is favored where it is possible, i.e. for none polluted or mixed product. At some point after repeated use, the material may commence to degrade, by then it is destined to energy conversion or total breakdown subjected to incineration, gasification or pyrolysis. This work considers the material recycling of LDPE. LDPE represents nearly of 8-10% of the total MSW waste received at the landfill. Initially thermal analysis based on Simultaneous Thermal Analysis (STA) and Differential Scanning Calorimetry (DSC) is carried out to observe the plastic thermal behavior of two successively molded samples. The samples are remolding using the thermosientific mini extruder and the HAAKE MiniJet II injected. The mechanical and thermomechancial properties are assessed using uniaxial static and dynamic tests under well controlled conditions. Mild variation is obtained in the thermal behavior to the two samples observed by the similarity in melting, extent of thermal stability, and onset and end of degradation. However, the mechanical behavior between the three samples clearly demonstrates the gain in total modulus and lower tan delta for the cross-linked product but with a reversion to original LDP behavior following the molding of the waste. This work support successive material recovery for cable plastics with an additional cross-linking to the rejected waste.","PeriodicalId":130577,"journal":{"name":"2013 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126325527","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}

It is in this optic that the Algerian government creates Funds earmarked for a renewable energy supplied from 0.5% of petroleum rental. While solar energy remains the main focus of efforts to boost production from renewable energy, Algeria is looking at wind power by several projects, which will be integrated in the Algerian network. The main objective of this research work is to investigate the power quality issue to the transient stability problem caused by the wind power connection and consequently the enhancement of the rate of the wind power penetration limit without overloaded line and with an acceptable voltage level ensured by integration of flexible AC transmission system (FACTS) device such as Static Synchronous Compensator (STATCOM). Furthermore, in order to choose the adequate type of wind turbine, a comparative study between several types is established. It must be noted that all simulations are carried out on PSAT/Simulink. Finally, some meaningful conclusions and comments are given in this paper.","PeriodicalId":130577,"journal":{"name":"2013 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126541348","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}
