This realization is due to the significant developments and increase in reliance on renewable energy resources. Wind power stations acquired dominant investments in utility-scale projects known as wind farms [1]. Aligned with selecting proper sites, wind turbine assemblage has extensive impact on the overall productivity and efficiency of the power station. The proficiency of a Wind Energy Conversion System (WECS) is accompanied by competent election of generator and electrical control systems; where the latter is multiplied and expanded to structure an adept wind farm. This paper investigates, models and simulates a doubly fed induction generator (DFIG)-based wind power system coupled to a back to back power converter and controlled by a vector control strategy. The DFIG based wind farm is simulated under fixed step where results are conferred and assessed.","PeriodicalId":426643,"journal":{"name":"2018 4th International Conference on Renewable Energies for Developing Countries (REDEC)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129383932","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}

The mathematical models of the system’s components including the evacuated tube heat pipe solar collectors, the PCM, the hot water driven lithium bromide absorption chiller, the heating system, and the domestic hot water tank were coupled in a fully programed calculator developed using \"Visual Basic ©\". The thermal and electrical consumption baselines were hourly simulated using the \"Design Builder\" Program, and then entered to the calculator to find the system’s optimized collectors and storage sizes.A feasibility study comparison shows that \"The All-Centralized\" is better than \"The Semi-Centralized\" configuration for integrating this system in a smart network for a group of 100 villas located in Riyadh KSA. Finally, applying a demand response scenario increases the system’s reliability through its ability in serving up to 7 % more of villas with the same installed smart network.","PeriodicalId":426643,"journal":{"name":"2018 4th International Conference on Renewable Energies for Developing Countries (REDEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127484204","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}

Nowadays, anaerobic digestion, as a green technology, is widely used to convert organic waste, into methane, and subsequently, into bioenergy. In this study, our main objective was to evaluate the feasibility of applying anaerobic digestion to treat Lebanese olive by-products, in particular olive pomace. Biochemical fractionation of our biomass showed high contents of cellulose (55.4% of total solids) and lignin (21.3% of total solids) which could limit the anaerobic digestion and result in low methane yield. Biochemical methane potential was assessed using anaerobic digesters in batch mode. These digesters containing the substrate and inoculum in a ratio substrate to inoculum of 1:3 (total solids basis) were incubated at 37°C. Results from anaerobic digestion showed that olive pomace is a great source of green energy. Alkaline pretreatment was effective in altering the lignocellulosic fractions of olive pomace. But when pretreated samples were subjected to anaerobic digestion, an inhibition occurred because of the formation of toxic compounds, mainly when higher NaOH dosages were used. Alkaline pretreatment also influenced the methane production rate constants and slowed down the anaerobic digestion process.","PeriodicalId":426643,"journal":{"name":"2018 4th International Conference on Renewable Energies for Developing Countries (REDEC)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125610296","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}

Although time-varying electricity price, demand response, and incentive programs are suggested in many papers as solutions to smooth the peak-load, the results are not satisfactory. For example, in the presence of a dynamic price, all PEVs at homes tend to charge during periods when the electricity price is low. They may create peak demands that exceed the transformer power limit in unexpected periods when the power consumption is low. The situation gets worse when a fixed price is used in some countries and regions. PEVs tend to charge at any time without considering the presence or not of a peak load. To solve the problem of high penetration level of PEVs, we propose three novel contributions as follows, (i) a novel power Soft-Constraint at home level, (ii) a novel Multilevel Power-based Soft-Constraint, and (iii) a new Multilevel Power-based Electricity Tariff System are proposed. Simulation results show that our approach improves the integration of PEVs even when high penetration level is considered and even when fixed electricity price is used.","PeriodicalId":426643,"journal":{"name":"2018 4th International Conference on Renewable Energies for Developing Countries (REDEC)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133708512","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}

Solar water heating system is transient in nature and its performance depends on dynamic parameters. Transient system simulations using SimSol and Solo softwares are done in order to assess the performance of the solar water heater for different weather files and component parameters. In a first step, the analysis was based on a definition of Domestic Hot Water demands performed by the scientific and technical center for building . Afterwards, 16 single component parametric variations for Centralized and Individual SWH are performed and analyzed. The results showed that the different parameters may increase the solar gain energy and reduce the heat losses through the system components. Impacts of these parameters are quantified for weather conditions in Lebanon. A simplified sizing procedure for solar domestic hot water systems is also presented. Finally, Requirements for the Chapter Hot Water of the Lebanese Energy Building Code are proposed based on the simulation results as a minimum energy efficiency measures which demonstrate the purpose of this endeavor.","PeriodicalId":426643,"journal":{"name":"2018 4th International Conference on Renewable Energies for Developing Countries (REDEC)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132265122","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}
