The design procedure consists of computation of limiting requirements and rigorous simulation using material and energy balances. The results of the proposed design are compared with those of the conventional two-column system; the comparison shows that the fully thermally coupled distillation column requires 30.8% less energy than conventional system. From the required energy, the thermodynamic efficiency of fully thermally coupled distillation column is higher than that of conventional distillation system in the separation of the ternary mixture considered in this study.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129115789","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 circuit topology and the switching pattern of the boost inverter boosts up a low voltage DC (e.g. photovoltaic panel or fuel cell) of a sustainable energy source to inject the required filter currents. The proposed boost inverter can perform load balancing, harmonic compensation and reactive power control while supplying real power to the grid. In a PV based boost inverter, PV panels of low output voltage can be connected in parallel, and eventually, a panel's defect or malfunction will not affect the operation of the whole system significantly. The boost inverter's switching are controlled by the Power Balance concept. This inverter topology is connected to the Point of Common Coupling (PCC) of the distribution system. The reference waveform generated from instantaneous symmetrical component theory are used further to generate instantaneous boost reference parameters. These boost reference parameters are then tracked by the boost converters to inject the desired filter currents into the corresponding phase.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122636135","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}

Also, the paper identifies different issues in rural electrification in changing context and different initiatives taken so far on connection of micro hydropower and mini grid development. The study reveals that grid connection and mini grid initiatives are not internalized and owned by the policy and institutional mechanism. Policy and institutional mechanisms need to be revised and restructured so as to adopt mentioned initiatives and to introduce synergy effects which are not often realized because of parallel policy and institutional mechanism. The policy and institutional mechanisms should develop suitable financing/investment mechanism not only based on subsidy but also on the principle of private sector involvement, business operation modality especially trading mechanism, technology transfer and capacity building, and institutional structure of mini grid based on decentralization and liberalization which could encourage competition in the sector as whole. Such policy provision and institutional mechanism make the flow of financial resource from urban to rural and also retain the human capital in the local level.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132192007","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}

But the requirements for commercial fuels like kerosene eats away their petty incomes. In this regard, this paper investigates on the basis of a case study the adequacy of the Hybrid Solar Wind Power System. Among the various renewable resources, hybrid solar and wind energy seems to be promising solutions to provide reliable power supply with improved system efficiency for hybrid stand-alone applications in off-grid rural areas. This paper presents a method to investigate the reliability of small standalone Hybrid Solar/Wind Power System (HSWPS). The analytical reliability assessment methodology is to carry out the reliability indices of HSWPS. The base case study taken is the first pilot project on wind power in Nepal funded by Asian Development Bank (ADB) and implemented by Alternative Energy Promotion Center (AEPC) namely Dhauwadi VDC of Nawalparasi Electrification Project.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123481757","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 main goal of this paper is using magnetic resonance to supply power wirelessly via air and to determine the dependency of power supply on coil dimensions and other factors. Different types of source and load coils are analyzed like circular, spiral and helical. Different shapes of the coils are also taken into account like square and circular. From the analysis, it is found that the efficiency of power transfer is derivable by the equivalent circuit point of view and also using coupled mode theory. The analysis shows that the efficiency is dependent on the coil radius, distances between the coils and the Q-factors of the coils. From the analysis, an overview of the optimum design of the coils and distance between the coils has been given.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126671091","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}

Its steady-state operation and analysis for wide input voltage and varying power transfer capacity are discussed. Interleaving two full-bridge current-fed converters reduces the input current ripple. Phase-shift modulation with parallel input series output interleaving is adopted. The power density of the converter increases with small devices' ratings and less current/thermal stress on the semiconductor switches. The converter utilizes the energy stored in the transformer leakage and magnetizing inductance to maintain zero-voltage-switching over wide range of source voltage and load variation. It improves the converter efficiency and allows high switching frequency operation.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129682975","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}
