Analysis for differences in the annual electric energy produced by twenty wind turbines of same model was carried out. Data related to wind farm were obtained from site and used in the calculations. Results of analysis showed that monthly system availability during May to August was having a significant effect on the annual performance of turbines. It was also observed that annual system availability was not the major factor affecting annual energy yields. Location of a wind turbine within the wind farm may also influence the annual energy yield of the turbine.","PeriodicalId":109404,"journal":{"name":"2014 1st International Conference on Non Conventional Energy (ICONCE 2014)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125193216","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}

Post disaster, one of the most immediate and important need is to setup a communications network, which is not feasible by conventional means. This paper describes the design of working prototype of a totally self-contained and easily re-locatable system, which can provide necessary power for communication equipment. The power will be generated by solar panels mounted on the top of the envelope of an aerostat, which is an aerodynamically shaped balloon filled with a lighter-than-air gas, and is tethered to the ground. The entire system will be mounted on the chassis of a truck or trailer, to make it easily re-locatable. In this study, a commercially available, light-weight flexible amorphous silicon solar panel with a peak power output of 64 W was procured and tested. A prototype aerostat envelope was fabricated, and a provision was made for integration of the solar panel on the top of the envelope, with a thermal insulation layer. The envelope was leak tested and an existing winching system for ground handling of the system was readied. The technical feasibility of this system has been established via the conceptual design, sizing and fabrication of a working prototype.","PeriodicalId":109404,"journal":{"name":"2014 1st International Conference on Non Conventional Energy (ICONCE 2014)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134411940","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 model has been implemented in MATLAB as well as a simulation has been verified in LabVIEW. The simulation has been designed to be very user-friendly and conveniently alter the various dynamic conditions and observe the responses. For the purpose of validating the model, a comparison has been made by using experimental data from the PEM fuel cell testing.

ELD is a significant optimization problem in power system to distribute load demand reasonably and scientifically so that fuel cost can be minimized while satisfying various operational constraints.

The thermal behavior of the developed materials is tested in comparison to natural materials that are used in the external building surfaces. Prior to the tunnel experiments, all materials are characterized with techniques like XRF, XRD, SEM, nitrogen and water vapor adsorption-desorption isotherms, thermal conductivity and reflectance measurements. In cyclic experiments inside the tunnel with simulated solar irradiation, the maximum temperature reduction due to the implementation of the water vapor cycle in the porous material is determined. The utilization of different parts of the solar spectrum for simultaneous multifunctional purposes (like UV-VIS for photodegradation and IR for providing the thermal energy for phase changes) by supporting semiconducting oxides on hydrophilic porous materials, is feasible.","PeriodicalId":109404,"journal":{"name":"2014 1st International Conference on Non Conventional Energy (ICONCE 2014)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115162452","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}

Biofuels play a crucial role in mitigating CO2 emission, reducing global warming and acting as potential cheap alternative in comparison with the soaring prices per barrel of petroleum. The production of algal biomass for biofuels combined with the production of bulk chemicals, application in wastewater treatment, aquaculture, food and feed ingredients as well as in human health is presently drawing attention in many countries.

Similar to network of solar cells, a network of metal is also made to carry the heat extracted from solar cell to the metal deposition and then to ambient. Thermal modeling based on energy balance of each component and analytical expressions of different parameters of a single solar cell (SSC) of glass-glass type PV panel have been derived.
