The optimal cost analysis of HRES is done using Hybrid Optimization Model for Electric Renewable (HOMER). The HOMER energy modeling software is a powerful tool for designing and analyzing hybrid power systems. It is currently used all over the world by tens of thousands of people. HRES provides the electrical power for a remote located area. In this work, real time optimal cost analysis of HRES is done based on the load profile, solar radiation and wind speed which were collected from Mandapam in Ramanathapuram District, TamilNadu. HOMER is used here to optimize the system based upon the Total Net Present Cost (TNPC). Moreover, the optimization of system is obtained by varying the sensitivity Variables like solar radiation, wind speed etc.. Cash flow summary of the HRES system is obtained which will be useful for the optimal cost allocation of each individual component present in the system.","PeriodicalId":411175,"journal":{"name":"2013 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114722634","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 involves a careful system design, since requirements are very strict, battery life-time maximization, robustness, recovery strategies, network flexibility and re-configurability. This paper implements zigbee based wireless sensor network in agriculture such as monitoring of environmental conditions like weather, soil moisture content, soil temperature, soil fertility, weed detection, water level, monitoring growth of the crop, precision agriculture, automated irrigation facility and storage of agricultural products. The aim of this project is to monitor and maintain the farm from any part of the world through internet. Monitoring is done with the help of wireless sensor networks and all the control process is done with the help of the microcontrollers. Wireless cameras are used to feed live video of the farm to any part of the world. With the help of this project, modern technologies and new ideas can be implemented in the farm sector of our country. A farmer can see the real condition of his farm and also control his farm from any part of the world by logging into farming website. This makes the Indian farmers feel comfortable and reduces the risks involved in irrigation. The idea has the potential to attract entrepreneurs to invest in the agricultural sector.","PeriodicalId":411175,"journal":{"name":"2013 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129425217","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}

In this regard, distributed generation will continue to play a critical role in the energy supply demand. The common technologies available as DG are micro-turbines, solar, photovoltaic systems, fuel cells stack and wind energy systems. A dynamic model of solid oxide fuel cell is done. Fuel cells operate at low voltages and hence fuel cells need to be boosted and inverted in order to connect into the utility grid. A DC-DC converter and a DC-AC inverter were used for interfacing SOFC with the grid. The output voltage and current waveforms of the DC-AC inverter, load and grid are analyzed for various load for grid connected applications.","PeriodicalId":411175,"journal":{"name":"2013 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125574827","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 proposed work decomposes this problem into two sub-problems and proposes security solutions to each of them: (1) to secure the link between the patient and the device, and (2) to secure the link between the device and the network. Biometric identification is extremely an effective authentication. Thus we push the limits of the network security to the edge by authenticating the user using their biometric information; authenticating the device to the network at the physical layer and strengthening the security of the wireless link using steganography. The proposed authentication methods can be used for recording the medical data in a central database and for accessing medical records in various settings.

This method achieves the variation of Total Harmonic Distortion (THD) in the inverter and output voltage is observed from various modulation indices. Simulation is performed using MATLAB-SIMULINK.

The performance of a neural network to a large extent depends upon the type of architecture used and their learning algorithm. Eight commonly used domestic loads are identified and their harmonic signatures obtained. The data is used to design a Feed Forward neural networks (FF) and Single Neuron Cascade networks (SNC). The performance of these models was compared in terms of their recognition accuracy and network complexity. Both the networks are shown to perform well in terms of accuracy.
