The improved SVM manage to produce a balanced three phase output voltage under non-linear load condition compared to the previous work where it only works in resistive load condition. The improved SVM considers the switching sequence in four different sectors while previous SVM technique for this topology consider the switching sequence in two different sectors only. The initial simulation results obtained from the MATLAB/Simulink showed that the proposed system is capable to produce a balanced output voltage under three phase balanced load conditions. A small signal modelling were also proposed to support the modulation technique for this topology to work under unbalanced load condition in future work.","PeriodicalId":275077,"journal":{"name":"2017 IEEE Conference on Energy Conversion (CENCON)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133224355","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 approach proposed by the authors generally explains the procedures of the PV module modeling process via the assisting works of real measurement and simulation. With the matching of the I-V curves between the simulated and measured data, the characteristic parameters can be determined with the resultant errors computed. Extensive works are added in the progress of data analysis and interpretation for results evaluation, in which further assist in the development of the algorithm using the renowned numerical software.","PeriodicalId":275077,"journal":{"name":"2017 IEEE Conference on Energy Conversion (CENCON)","volume":"370 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124636238","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}

One additional inductor and capacitor to the classical Cuk converter is added as voltage booster. Therefore, it minimizes the parasitic effects of the circuit components. Diverse classical DC-DC boost converter types are used in renewable energy applications. However, the output voltage is limited due to parasitic effects which cause voltage drop, and lower efficiency. Modified Cuk converter circuit overcomes these difficulties and maximizes the output voltage generation with higher efficiency. Numerical simulations conducted on Matlab/Simulink and validate the analytical analysis and accuracy of the modified topology.","PeriodicalId":275077,"journal":{"name":"2017 IEEE Conference on Energy Conversion (CENCON)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122096225","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}

Implementation of renewable energy (RE) sources into the grid generally requires load flow and short circuit analysis to study the contribution of RE system into the grid. However, the study involving arc flash assessment is not well known and therefore not mandatory in some countries for new installation of RE system. Arc flash assessment covers the safety aspect in terms of arcing current due to a fault at any location in a network. Therefore, a comparative study for both 17kW and 255kW PV system is conducted using arc flash assessment to evaluate the hazard level between the two and analyzing the correlation of arcing current intensity and personal protective equipment (PPE) used to minimize the hazard. Both of the PV networks are designed and simulated using electrical power system or ETAP.","PeriodicalId":275077,"journal":{"name":"2017 IEEE Conference on Energy Conversion (CENCON)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115489920","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}
