In this study, three plants (a) Eugenia oleina (b) Muntingia calabura (c) Buxus sinica var (boxwood) have been selected due to their abundance in University of Malaya, Malaysia. Isopropyle alcohol has been utilized to extract the natural dye pigments from the falling leaves of these plants. Cocktail of these natural extract has also been investigated which displayed highest efficiency due to high light absorption ability. Another objective of this study is to use the spent leaves after extraction of dyeas fuel for heating purposes. The gross calorific value (GCV) has been measured using bomb calorimeter. The GCV values of individual and combined spent leaves were almost the same with very little difference. The maximum GCV value displayed by pellets prepared by spent leaves of Muntingia calabura was 16.84KJ/g.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"24 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78658854","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}

These abrupt qualitative transitions are crucial in deciding the stable operating regime in the case of a power system. However, in the actual power system, the control parameters such as the electrical power demand, the inertia of the system, damping of the system etc. are found to vary with respect to time. In this paper, bifurcations in an electrical power system for the quasi-static and rate dependent variation of the control parameters are investigated. The canonical power system is represented by assuming a single machine connected to an infinite bus (SMIB). The mathematical modeling of the canonical system is carried out by a second order swing equation model of the generator. We observe a delay in the point of transition for rate-dependent variation of the control parameter, mechanical power, Pm. We also investigate the influence of noise and sensitivity to initial conditions in rate-dependent variations of the control parameter. Our study is highly relevant as the stability regimes for the quasi-static and rate dependent variations of control parameters are different.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"7 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81824437","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 has created the \"Data Centre Business and Industry\" which will continue to grow with e-commerce, mobile users, social media, internet of things, smart grid and smart cities. Data Centre’s energy consumption and energy prices (cost) are increasing due to growing demand for Information and Communication Technology and Services. Thus, it has become increasingly important to focus on energy efficiency and sustainability to stay competitive and provide better services for Data Centre operators. Energy efficiency also reduces the carbon footprint by three times as one unit (energy) saved at consumer will save 3 units (energy) at the source. In addition, Energy Efficiency supersedes the benefit of using renewable energy in reducing carbon emissions. This has led to Green ICT initiatives to enhance energy efficiency in ICT devices as well as using ICT devices. Several countries conducted Benchmarking Energy Efficiency of Data Centres, namely US (2007), EU(2010), Japan (2011), Singapore (2012), India (2012 & 2014) and Malaysia (2015) This paper presents Benchmarking Energy Efficiency in Tropical Data Centres and proposes recommendations for Data Centre Industry to stay sustainable and competitive and reduce emission.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"8 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77111943","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 selected site was Sahacogen Green Co., Ltd. plantation area covering Lamphun and Lampang province. The investigated data of energy and economy were based on the data from experimental plantation and recorded data from the company, which included seedling, soil preparation and conditioning, cultivation, stump removal and soil recovery, harvesting and transportation. Eucalyptus plantation has been established since 2008 with a 2. 0 × 3. 0 m2 spacing. It was managed as a Short Rotation Coppice (SRC) which was first harvested at the 4th year following by 3 rotations of every 3 years. Stumps were removed, and soil recovery was counted at the end of 13th years. For biomass harvesting, saw cutting machine, tractor and Vermeer BC1000XL were used for woodchips production in the field at the end of each rotation period. Woodchips were transferred by truck to the steam power plant warehouse. The results of evaluation showed that woodchips production was characteristics of a highly efficient energy system with Cumulative Energy Demand (CED) 22.34 MJ/GJ of biomass and Net Energy Ratio (NER) of 44.76. The monetary values refer to cash inflows/outflow accomplished at the end of the cultivation period (2021) when assuming the woodchips price of 31.25 USD/t 40 wt% moisture, discount rate of 5.0% and inflation rate of 0.0% for 13 years on average indicating 1828.40 USD/ha which is equivalent to 2.46 USD/GJ. The economy of woodchips production project in terms of Net Present Values (NPV) and Internal Rates of Return (IRR) was −159.18 USD/ha and 3.94%, respectively.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"26 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":"82259772","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}
