Long-term co-firing tests were performed with two alternative bed materials, pure alumina sand and a mixture of alumina sand and silica sand (in equal wt.%), to mitigate bed agglomeration. All experiments were performed with constant operating parameters (total heat input to the reactor, energy share of the reburn fuel, excess air, and secondary-to-total air ratio). Physical and chemical characteristics of the bed materials and particulate matter were quantified at different time instants. The study showed weak effects of the bed material type on combustion and emission performance of the combustor. When co-firing the selected biomass fuels, high (over 99%) combustion efficiency can be achieved at about 45% NO emission reduction, as compared to firing the base fuel alone. Using the selected bed materials, bed agglomeration can be prevented in the combustor for a relatively long operating time. However, the bed materials showed time-domain changes in physiochemical characteristics and a diminishing capability to resist bed agglomeration, particularly when using a mixture of alumina and silica sand.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"36 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84665286","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}

Due to the increased variation between supply and demand, the power produced by the conventional generators is not sufficient to meet the load demand. Renewable sources are added to the system, to provide additional power to avoid the generation and load imbalances. When the power demand is met, the extra power can be sold back to the grid to yield monetary benefits. In case if, the power demand is not met by the conventional sources as well as the renewable sources, the power is drawn from the grid to meet out the demand. Two scenarios have been considered, with and without the addition of renewable penetration into the system. When renewable sources are not added to the system, the fuel cost and maintenance cost is high due to the conventional generator which supports the demand. When renewable sources are added, the fuel and maintenance is considerably reduced. In this study, renewable sources are free of cost.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"383 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75522658","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}

Nevertheless, Vertical Axis Wind Turbine (VAWT) titled Savonius Wind Turbines have many advantages over HAWT and Darrieus VAWT.This research aims to model, design and analyze the performance of different bladed Vertical Axis Wind Turbine (VAWT) by considering different design parameters.

It was carried out through the Asia—Pacific Integrated Assessment Model (AIM/Enduse), which is a bottom up type least cost optimization framework. A business as usual scenario and four alternative mitigation policy options were considered in this study. These policy options include two scenarios with 100 $/tonCO2, 500 $/tonCO2 carbon tax, a subsidy scenario with tax rebates for electric, hybrid vehicles and a scenario which promotes pubic transport. The results show that the transport sector energy consumption is expected to increase from 5 Mtoe in 2015 to 19.5 Mtoe in 2045. The CO2 emissions are expected to increase from 15 Mton in 2015 to 58 Mton in 2045. Out of the four scenarios, promoting public transport was most effective as it could reduce energy consumption by 52% and reduce CO2 emissions by almost 36% in 2045. At current electricity prices and other costs, electric vehicles are not found to be economical in the analysis.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"158 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77534311","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}

Identification of weak nodes in power system may be useful for system operators for actuating suitable controls to prevent voltage instability. Time series evolution of the conditional number of power flow Jacobian matrix is utilized in this paper to identify the weak nodes in the system. If the conditional number value goes beyond the threshold value, then the generators with minimum reactive power margin and loads with maximum change in nodal reactive power loss within the zone are identified. All these generators and nodes within the zone are ranked, the generator with minimum reactive power margin and the node with highest change in nodal reactive power loss in the minimum reactive power margin zone is the weakest node. This methodology is validated in New England 39 bus test system and the simulation results shows that this methodology is effective in identification of weak nodes in the power system.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"11 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81299543","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}

During the growing stage, this species can grow up to 1 m in height per year and tolerates to harsh environmental conditions. Its seed provides high levels of non-edible oil, thus making it ideal for biodiesel production. In addition, during the biodiesel production process, its waste and by-products can be used as a raw material in pharmaceuticals and cosmetic industries, and as a compost for soil enrichment. Growing various cash crops with Calophyllum inophyllum as agroforestry can provide extra income to farmers, thus create added value of Calophyllum inophyllum cultivation.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"3 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84264197","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}
