A centralise tower consisting of heat transfer fluid which circulates throughout the plant. There are so many different kinds of heat transfer fluids (HTFs), each have different thermal and physical properties. In order to fulfil the energy requirements in rural areas, CSPP can be viewed as an alternative source for power generation ranging 10kW up to 1–2MW production capacity. Today, number of CSPP has already been installed at different locations along with large power capacities. These installed CSPP uses different types of HTF such as, therminol VP-1 synthetic oil, dowtherm A, etc As per govt. of India's central electrical authority report 2016, India produces 61% of electricity from coal which may depleted soon. But still India is unable to fulfill energy demand all over the country with non renewable energy sources. So they need some alternate sources of energy to bridging the gap between the demand and supply. In this paper we are reviewing the various properties of each heat transfer fluid with reference to CSPP in India. Then suggesting to utilize halide based salt in these plants for small scale power generations in rural areas and utilizing phase change material for two purpose, first to be working as a heat transfer fluid and second is to be using as heat storage material. This article also explains that how the solar radiations are concentrated to a solar power tower with the help of heliostats specifically for small capacity power generation unit, and thus to install small capacities solar power tower within the Indian smart cities with the help of different heat transfer fluids.","PeriodicalId":339848,"journal":{"name":"2016 21st Century Energy Needs - Materials, Systems and Applications (ICTFCEN)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128870037","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 thinner absorber layer has two main advantages (i) it reduces the material consumption and (ii) minimizes the time and energy required in production. For thin film silicon (Si) technology, thinning down the absorber layer is of particular interest since the device throughputs of vacuum deposition systems as well as the stability of the devices are significantly enhanced. The 3D nanorod structure in thin-film photovoltaics has got much attention due to their enhanced light trapping capability, and it also requires less thick active layer. The enhanced light trapping results in more efficient absorption of spectrum within the solar cell structure. This gives the higher short circuit current and hence higher power conversion efficiency. We have developed the ZnO nanorods on the glass substrate through galvanic cell based approach and designed a nanorod solar cell through numerical simulations using technology computer aided design (TCAD) tool. Numerical simulation shows that the highest conversion efficiency of 9.12% is obtained for the zinc oxide nanorod solar cell which is nearly 18.59% more than the planar a-Si:H solar cell with same absorber layer thickness.","PeriodicalId":339848,"journal":{"name":"2016 21st Century Energy Needs - Materials, Systems and Applications (ICTFCEN)","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124919090","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}

Considerations of thermal effects in Lithium-ion cells (related to cycle and calendar life) are important for the safety issues because higher temperature may leads to the thermal runaway. Electro-thermal modeling enables us to understand the thermal behaviour of cells, quantification of heat generation inside the cell and changes in cell chemistry at the time of battery operation. The various electro-thermal models of Lithium-ion cells have been investigated using methods like control volume, finite elementary, differential method. Substantial diagnostic and practical modeling efforts are required to fully understand the thermal and electrical characteristics of the Lithium-ion cells across various operating conditions for higher discharge rate. Higher discharge rate (approximately 10C) is preferred for some particular application like Torpedo, underwater vehicles etc. Several factors associated with cell fabrications, such as electrode thickness, compactness, electronic conductivity etc, need to be optimized to achieve better cell performance at higher discharge rate. Thermal behaviour of the cell at high discharge rate is another important issue that must be address properly to mitigate safety related concerns.","PeriodicalId":339848,"journal":{"name":"2016 21st Century Energy Needs - Materials, Systems and Applications (ICTFCEN)","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121619081","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}

Power distribution systems with wind generation units like Doubly Fed Induction Generator (DFIG) are bound by the standards like IEEE 1547 to detect formation of power islands and disconnect the DFIG from the system. This approach is not an economically viable option as the DFIG system with appropriate control may successfully continue to supply power to the local loads and hence operate as an islanded Microgrid. However, this decreases the time frame within which islanding detection relays (IDR) must operate. This paper presents a comparative study of advanced techniques based on the principle of a classic Rate of Change of Frequency (ROCOF) relay that has been proposed in recent research works for utilization in distribution systems with DFIG. This work evaluates these IDRs in terms of their operating characteristics. Simulations have been carried out in PSCAD to obtain the operating curves and to assess the vulnerability of these IDRs to non-islanding transient. The effect of these techniques on power quality is also highlighted.","PeriodicalId":339848,"journal":{"name":"2016 21st Century Energy Needs - Materials, Systems and Applications (ICTFCEN)","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123009535","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}
