The sophisticated tool helps clinician to understand the cause of patient's particular health issue. RF Phased Array coils are used in MRI for better signal reception as they are more sensitive to signal close to the coil, thus detecting signals from organ of interest more efficiently. Hence attempts are made in order to improve the performance of the coil with respect to its signal to noise ratio, penetration depth, Specific Absorption Rate, etc. Phased Array coils are nothing but a number of overlapping surface coils. In this paper, we have designed, simulated and fabricated the MRI surface coil by overlapping to form phased array for 1.5 Tesla scanner. A balun is designed to feed the unbalanced coaxial signal to a balanced coil Return loss of single coil is 21.96 dB and that of array is 25.84 dB and reverse isolation is 37.08 dB with bandwidth of 7.6 MHz. Simulation and experimental result have been compared to validate the proposed design of single coil.","PeriodicalId":6552,"journal":{"name":"2015 International Conference on Technological Advancements in Power and Energy (TAP Energy)","volume":"27 1","pages":"165-169"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90929489","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 Flow Studies play a vital role in planning the future expansion of power system as well as for deciding the optimum operation of the existing power system. The uncertain and unbalanced nature of DG sources demand unbalanced power flow studies for analysing the DG integrated distribution system. DG sources such as Photo Voltaic(PV) installed in a distribution network are the major concern in this study. The randomness associated with the power production from the PV source should be modeled as a multistate variable in the power flow studies. The paper presents an unbalanced power flow algorithm based on the current summation method for the distribution system with the photovoltaic source. The uncertainty associated with the solar irradiance is modeled using Beta Probability Distribution Function(Beta PDF). The proposed algorithm is validated with IEEE 13 bus distribution feeder.","PeriodicalId":6552,"journal":{"name":"2015 International Conference on Technological Advancements in Power and Energy (TAP Energy)","volume":"12 1","pages":"29-34"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91198266","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}

Ravishankar","doi":"10.1109/TAPENERGY.2015.7229665","DOIUrl":"https://doi.org/10.1109/TAPENERGY.2015.7229665","url":null,"abstract":"Micro grid consists of a cluster of distributed energy resources (DER) connected at the point of common coupling. Amount of renewable energy penetrated into the grid must be monitored and controlled for the stable and reliable operation of the grid. An efficient communication system interacts between DERS's and the utility substation is required to perform the task. DER inverters are capable of providing real and reactive power support according to the grid requirement. This paper discusses about an efficient control to economically allocate the available DER based on cost analysis. A supervisory price controller (SPC) and a Distributed Energy Resource Controller (DERC) provides the initiation signal to bidirectional voltage source inverter of the selected resource which is then responsible to provide real power support to the AC and DC loads connected to it. Apart from this service, the inverter using the control algorithm also provides reactive power compensation, current harmonics mitigation and load balancing so that the supply currents are always sinusoidal and at unity power factor. Instantaneous Symmetrical Component Theory (ISCT) is used to provide the inverter all these functionalities. The centralized operation of micro grid under varying energy price is demonstrated. A MATLAB/SIMULINK model has been developed and simulation results shows the effectiveness to provide active power and ancillary services according to changing prices due to the coordination between the participating micro resources.","PeriodicalId":6552,"journal":{"name":"2015 International Conference on Technological Advancements in Power and Energy (TAP Energy)","volume":"194 1","pages":"472-478"},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89026090","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}
