This problem can be solved effectively by using a technique called network reconfiguration. It is useful to reduce the real power loss and to keep the voltage magnitude within the limits. The proposed work is presented by using Johnson's algorithm which is used to calculate the total minimum impedance to reach the destination feeder. The main purpose of the proposed work is to obtain the shortest path, so that the real power loss can be minimized and voltage regulation can be improvement. Therefore, the proposed algorithm for reconfiguring the network is investigated on IEEE test systems 33 and 118 radial distribution system and their performance is tested with distribution load flow analysis for comparing the real and reactive power loss before and after network reconfiguration.","PeriodicalId":134828,"journal":{"name":"2018 4th International Conference on Electrical Energy Systems (ICEES)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128367601","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}

Since these parameters affect the device ON and OFF currents, the studies are done by (i) constraining ON current (ii) constraining OFF current and (iii) without constraint. It is found that higher channel doping and lower substrate doping result in higher ION. Also lower channel doping and higher substrate doping gives lower IOFF. Better $mathbf{I}_{mathbf{ON}}/mathbf{I}_{mathbf{OFF}}$ ratio is achieved with heavy substrate and channel concentrations. Better $mathbf{f}_{mathbf{T}}$ and $mathbf{I}_{mathbf{ON}}/mathbf{I}_{mathbf{OFF}}$ ratio can be achieved at lower spacer lengths with ION constraint, using high K spacers.","PeriodicalId":134828,"journal":{"name":"2018 4th International Conference on Electrical Energy Systems (ICEES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130879625","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 first frequency band that was allocated for communication purpose was C-band (4–8 GHz). Achieving a compact size with improved bandwidth, gain, directivity of an antenna has been an important issue, especially for the satellite based application. Using dual orthogonal microstrip tapered feed lines, a broadband monopole antenna having dual circularly polarization is designed for C-Band applications. The modified ground plane structure generates circular polarization. Once CP is generated new challenges such as wide axial ratio, impedance bandwidth will arise. The design of combination of Inverted L-shaped Strips (ILSS) and L-Shaped Strips (LSS) along radiating edges of monopole maximizes the axial ratio and design of bevel at lower edge of monopole will improve the reflection coefficient for wideband impedance matching. The antenna is designed and simulated using HFSS software of version 17. The frequency of operation is from 1.4 to 9.0533 GHz (146%) with maximum reflection coefficient of −43.2321 dB. Since good 3-dB AR Bandwidth is achieved for the range of 4.84 to 7.52 GHz, this antenna can be used for the C-Band applications like WIFI (5.15-5.85GHz), WIMAX (5.15-5.85GHz), WLAN (5GHz, 5.2GHz, 5.8GHz) and C-band wireless system. Peak gain of 4.958 dB is achieved at 7.5 GHz and peak directivity 5.1108 dB is achieved at 5.7 GHz respectively","PeriodicalId":134828,"journal":{"name":"2018 4th International Conference on Electrical Energy Systems (ICEES)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125525240","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}

Solar energy is being converted to various forms such as heat, electricity etc. Solar panel has Photovoltaic (PV) arrays which directly converts light into electricity. The best PV cell has an efficiency of up to 30%. Hence output power is small for input that it takes. Therefore, panel is required to operate at its maximum power point (MPP) to achieve high efficiency. The output characteristics of PV module depends on the solar irradiance, temperature and output voltage of PV module. As the PV cell has nonlinear Current - Voltage (IV) and Power - Voltage (PV) characteristics, it is necessary to design a control circuit or algorithm so that the cell is tuned to operate at MPP irrespective of the load connected and external parameters variations such as illumination and temperature. The panel output characteristics are nonlinear in nature; therefore, it is necessary to model and simulate for use in PV system applications. In order to improve the output efficiency of PV system, a novel variable step size perturbation and observation P&O method is proposed to track the maximum power point of PV system.","PeriodicalId":134828,"journal":{"name":"2018 4th International Conference on Electrical Energy Systems (ICEES)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116043901","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 low power sensor devices can measure vital signal such as heartbeat rate, blood pressure or temperature. The wearable device module has to be powered for continuous operation. An investigation into the design of stand - alone photovoltaic for wearable device application is presented. This paper focuses on supplying power to the wearable device from a flexible photovoltaic cell. A flexible photovoltaic cell is proposed to be fabricated using CuO/ZnO thin film by sputtering deposition method. For monitoring the health result the proposed system uses Bluetooth module which can acquire those vital signal and wirelessly communicate to our remote device e.g. mobile phone. A microcontroller is used as an interface between sensor and Bluetooth. A rechargeable battery is used as a backup. This paper uses a photovoltaic cell equipped with DC-DC boost converter and maximum power point tracker to optimize the maximum power available so as to simultaneously supply power to the battery and wearable device. This system is modelled using MATLAB SIMULINK. To extend the operational life of the overall system a flexible photovoltaic cell is proposed.","PeriodicalId":134828,"journal":{"name":"2018 4th International Conference on Electrical Energy Systems (ICEES)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133908772","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}
