It contributes to produce fast torque response and extended constant power speed range for SRM drives. Moreover, an adaptive activation mechanism is proposed to ensure the stability of drives under all operating conditions. Besides, the problems of high torque ripples and variable switching frequency experienced by conventional direct torque control are solved by employing a constant switching frequency based torque regulator and combining it with the proposed over-modulation scheme. Simulation and experimental results are provided to verify the effectiveness of the proposed approach.","PeriodicalId":415217,"journal":{"name":"2018 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131749999","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}

In an anti-islanding test setup, the load parameters R, L and C vary as they are dependent on the distributed generation (DG) rating. With the proposed emulation technique, the parameters R, L and C of the load can be controlled, while preserving the dynamic behaviour of the passive load, under all operating conditions. Two different current control methods for emulation are discussed. A two-level voltage source inverter (VSI) is used to emulate the RLC load. The results are verified using detailed time domain modelling in PSCAD/EMTDC for different type of DGs. The steady state performance of the proposed emulation technique is verified experimentally for different type of loads.","PeriodicalId":415217,"journal":{"name":"2018 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"255 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131789278","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, based on the EMI standards, the measuring of the EMI emissions of the equipment under test (EUT) could be very time-consuming. Conventionally, the fast Fourier transform (FFT) results of the noise signals are used to evaluate the EUT's EMI performance. However, these results are not compatible with EMI standards, and have large difference compared with the standard-compliant measurement. In this paper, a technique to predict the EMI noise spectrum of any input time-domain waveform is proposed. The simulator emulates the spectrum analyzer's performance based on EMI standards. The prediction results from the proposed technique match the EMI standard-compliant measurement results very well in a wide frequency range, with different power converter applications and modulation strategies. Meanwhile, the prediction results can be obtained in a very short time which is much faster than measurement process.","PeriodicalId":415217,"journal":{"name":"2018 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125230177","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 economic dispatch consists of three stages: 1). A first-order consensus protocol is adopted to obtain the optimal active power regardless of the voltage and frequency regulation. 2). To track the reference, a novel secondary-order consensus protocol is proposed. 3). To optimize the system frequency and voltage, another secondary-order consensus protocol is used to control the droop parameters adaptively. In this paper, the consensus protocol at each stage is fully distributed, in which each agent only requires its neighbors' information. Moreover, the system has globally asymptotic stability proved by the extended Lyapunov theorem. Lastly, simulation cases are studied to validate the proposed strategy.","PeriodicalId":415217,"journal":{"name":"2018 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131232929","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}

High partial discharge initiated from high electric field regions damages the insulation materials and leads to insulation failure. Therefore, the study of the electric field intensity distribution in all components of a high power density SiC-based converter and among multiple converters, if modular multilevel converter used, is needed. In this paper, a three-dimensional model developed in ANSYS of a high power density H-Bridge PEBB, benefiting from 10 kV SiC MOSFETs on a 6 kV DC bus, is presented. Using the finite element method, the electric field distribution inside the converter is calculated, and critical areas with high electric field intensities prone to initiate partial discharges are identified. Moreover, by using this model, geometry-based modifications are investigated to relieve high electric field regions. Finally, partial discharge tests have been applied to multiple critical parts, like the laminated bus and the interconnectors. It helps evaluate various insulation designs, provide some design guidelines and improvement suggestions for such application as well.","PeriodicalId":415217,"journal":{"name":"2018 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132886083","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}

Unfortunately, the traditional way of modeling power systems using a BB model abstracts the individual components that make up a highvoltage substation. These are critically important when assessing substation related faults which is a crucial step in attempting to make a more resilient grid. This paper presents a way of modeling typical substation protection schemes, using an augmented Bus-Branch (a-BB) representation, for contingency analysis applications. Further, the impacts and benefits of augmenting the IEEE Reliability Test System 1996 (RTS-96) system are described. The experiments in this paper show at least a 17% decrease in the number of non-converging power-flow solutions for all $N-2$ contingencies simulated on the augmented RTS-96 (a-RTS) system.","PeriodicalId":415217,"journal":{"name":"2018 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"23 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132939085","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}
