DC fast charging is random in nature. At peak load demand periods of the distribution network, the energy requirement may become as high as five times the normal peak load, due to DC fast charging loads. This paper proposes a load management strategy for integrating fast charging infrastructure with the grid. An energy management system with a charge scheduling algorithm is proposed to control the charging rate of the electric vehicles in the DC fast-charging station, effectively decreasing the stress on the grid during peak load. The results of the load management strategy are compared with rulebased system and DC fast charging station devoid of any energy management system. The main contribution of the paper includes an optimized energy management system framework for a DC fast charging station connected to a low voltage distribution network. The performance of the centralized energy management system is tested on a given network – peak charging power due to fast charging on the grid is reduced, the voltage constraints are satisfied (confined within ± 5% band of the system base voltage), and voltage deviation is minimized, without integrating additional ESS or PV system.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116989742","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}

To lower the optimization time, it is common to split the problem into subproblems, i.e., to optimize successively the flux barriers for the electromagnetic performance, and then the ribs for the structural integrity of the rotor. This however leads in general to a suboptimal design, because the cross-coupling between design parameter subsets (e.g., magnetic and mechanical) is this way ignored. In this study, different splitting optimization strategies have been implemented and evaluated by comparing not only the electromagnetic performance reached by the optimized designs, but also the computation time. Results show that the optimization time can indeed be significantly lowered by performing a magnetic optimization followed by a mechanical optimization, with little impact on the mean torque output. Pre-dimensioning analytically the radial ribs within the magnetic optimization further reduces the optimization time and improves the performance of the design. Finally, performing an additional iteration on the approach leads to a mean torque and torque ripple very close to the ones obtained by carrying the global optimization, with however half the optimization time.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116391738","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}

Using this procedure, new bearingless motor windings can be designed and conventional motor designs with MP windings can be transformed into bearingless motors by simply modifying the phase currents. The resulting MP winding is excited by two current components – one responsible for torque creation and another for suspension force creation. By applying the appropriate Clarke transformation, independent control of force and torque can be achieved. Although there are numerous papers in the literature studying bearingless machines with MP windings and their advantages, this is the first paper to provide a formal design procedure that can be applied to any MP winding configuration. The proposed approach can be used to realize popular winding designs, including concentrated- and fractional-slot windings. The paper uses the Maxwell stress tensor to formulate the force/torque model for the MP combined winding and uses the results to derive design requirements for the MP combined winding. A sequence of winding design steps is proposed and used to design example MP combined windings.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123540226","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, there is lack of a quantitative dynamic characteristics design method to determine the settling time and overshoot of a DC-DC converter in engineering applications. In this paper, firstly, the dynamic model of Boost converter is established by period averaging and small-signal linearization modeling. After that, the dynamic characteristics of the Boost converter is accurately represented by the eigenvalues of the closed-loop system through motion decomposition. Then, the eigenvalues region of the closed-loop system that satisfies the expected dynamic characteristics of the Boost converter is analyzed. Furthermore, the PI parameters that conFigure the eigenvalues of the closed-loop system to satisfy the corresponding dynamic characteristics area are calculated by the eigenvalue configuration. Finally, the effectiveness of the proposed dynamic characteristics design method is verified by PSIM simulation and experiment. The proposed method provides a reference for the dynamic characteristics design of the Boost converter.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121922190","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 converter includes a novel architecture where a stacked switched-capacitor (SC) stage provides an efficient course step-down and reduces the voltage swing for the transformer and inductive stage. Compared with a conventional Dickson SC converter, the new SC stage features an advantageous 2X reduction in maximum operating voltage for flying capacitors, enabling capacitor size reduction. Through the transformer, two inductors at the output stage provide soft-charge and soft-discharge operations for the primary side flying capacitors and ensure a lossless capacitive power transfer operation. To support higher input voltages and larger conversion ratios, multiple modules of the proposed converter can be stacked in a series-input/parallel-output configuration. This modular architecture provides advantages of differential power processing with reduced input voltage and processed power for each converter module. A prototype of the modular architecture has been demonstrated for a 100V-to-3V point-of-load conversion with a maximum load of 60A. The peak efficiency of 91% is achieved at 57W/20A output.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122061012","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}
