Both in balanced or unbalanced condition, the grid is supplied by the PV plant with the desired active power and with the developed strategy, it is possible to use the inverter as a reactive power compensator.

The flying capacitor multilevel H-bridge inverter uses many power semiconductor devices. In addition, two capacitors are used per phase in the inverter, although only one capacitor is required at applying 5-level voltage to the stator windings in an SRM. Therefore, the authors have proposed a novel asymmetric flying capacitor multilevel H-bridge inverter. This paper demonstrates through experiments that the proposed inverter is possible to output the same voltage levels as the conventional circuit during excitation interval. Moreover, the vibration characteristics of a switched reluctance motor are evaluated when the current hysteresis control is applied with the proposed circuit.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"21 1","pages":"971-976"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83871087","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}

Split-pi converter is a bi-directional voltage-fed input voltage-fed output converter. As most of the renewable sources are naturally voltage sources, this converter is very suitable for interfacing such sources. With interleaved split-pi converter can have smooth input current and output currents. The converter is simulated, and details of voltage and current stresses of the components are illustrated.

The software tools generally adopted for analytical studies are not suitable for the calculation of the arc-fault incident energy in the presence of capacitor banks. The reason for this deficiency is that the model of the electrical network is only valid for the analysis of short circuit currents at the fundamental frequency. The frequency of the outburst current from a capacitor bank is determined by the size of the capacitors and the impedance of the conductors connecting the capacitor bank to the fault. Given the large power ratings of capacitor banks at the substation of solar and wind farms, it is important to develop a method to determine the maximum contribution from these capacitor banks to the arc-flash incident energy.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"64 1","pages":"389-394"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90356659","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 network resonance has been described by IEEE 519 as a major contributor towards the harmonic distortion. Non-linear loads such as transformers, machines, silicon-controlled rectifiers (SCRs), solid state devices, power transistors, microprocessors and computers also contribute towards the injection of harmonics into a distribution system. The interaction between all kinds of elements of distribution systems and inverter based distributed generators like PV and Wind impacts the resonance modes to a definite extent. Based on the harmonic levels from the components in the system, the paper brings out a contribution in the form of a detuning methodology applied to a practical system to eliminate the harmonics. This would further serve as a recommendation for all the utility personnel and researchers. An exemplary North American system has been considered for the study towards detuning process. The phenomenon of resonance and harmonic issues has been inspired from a real situation due to capacitor switching towards power factor correction associated with an induction motor operating as an industrial load. Normally detuning is done on the capacitor banks when non-linear loads are active contributors to harmonics. Nowadays with more renewable penetration, this paper explores the observation during the interaction of renewables with the rest of the elements and an effective solution in the form of detuning to eliminate it is presented.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"50 1","pages":"435-440"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90550605","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}
