The LLC converter is a good solution for high power application, hence many PV systems which use LLC converter have been proposed. The combination of the LLC converter and a multi-level conversion technique is also proposed to overcome a drawback of the LLC converter. It is important on mass production stage to clarify the relationship between its voltage gain tolerance and resonant circuit component variations, however it has rarely studied. Therefore, we study the voltage gain tolerance against three normalized parameters related to the resonant circuit with Monte Carlo simulation. As a result, it has found that a conventional LLC converter and a three-level LLC converter have approximately same voltage gain tolerance characteristics; small inductance ratio makes the voltage gain tolerance to be small and a quality factor has an insignificant effect on the tolerance when a normalized frequency is almost unity; small tolerance area appears on a quality factor-inductance ratio plane when the normalized frequency is lower than unity.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"1 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":"122573263","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 paper also introduces, describes and implements a seven parameter model for photovoltaic cell (PV cell) which includes two internal parameters and five external parameters. To obtain the model the mathematical equations and an equivalent circuit consisting of a photo generated current source, a series resistor, a shunt resistor and a diode is used. The fundamental equation of PV cell is used to analyse and best fit the observation data. Especially bisection iteration method is used to obtain the expected result and to understand the deviation of changes in different parameters situation at various conditions respectively. The produced model can be used of measuring and understanding the actions of photovoltaic cells for certain changes and parameters extraction. The effect is also studied with I-V and P-V characteristics of PV cells though it is a challenge to optimize the output with real time simulation. The working procedure is also discussed and an experiment presented to get the closure and insight about the produced model and to decide upon the model validity. At the end, we observed that the result of the simulation is very close to the produced model.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"30 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":"122579701","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}

However, when they are operated as autonomous systems, several technical problems related with its operations and control has emerged as a challenge. To overcome this impending issue, this paper proposes an optimized approach by implementing adaptive solar PV generators with MPPT control (maximum power point tracking) to support an islanded microgrid in a low voltage network. Due to improper control and high maintenance, the PV generator provides very low efficiency during conversion. Therefore, the proposed strategy offers an effective coordination between inverter V-f control (voltage and frequency) and P-Q control, MPPT control and energy storage control of the islanded microgrids to remove device fluctuations and deviations. Also, the control strategy employed take care of State of Charge (SOC) stabilization of battery unit. The simulation of the proposed model is carried out in Matlab/Simulink. The results clearly confirm the potency of suggested controlling and adaptive strategy.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"35 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":"130631614","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}

Protection of DC microgrid is a significant challenge and to build a well-functioning protection system, locating faults accurately is important. This is especially the case with the location of ground faults in DC microgrid because of the high likelihood of capacitors connected to ground associated with the connected distributed resources. The focus of this paper is to apply Wavelet Transform to decompose the common mode currents which are collected at different sensor points in a community DC microgrid and methodologies for the capture and characterization of single ground faults at different locations within the microgrid. Based upon these characterizations, a single ground fault location algorithm in DC microgrid is proposed. MATLAB/Simulink and PLECS are used to assist in the process. A community DC microgrid model is built based upon the sharing of energy resources among interconnected homes and single ground faults at different locations are applied.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"22 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":"123955965","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}
