The EV owners tend to charge their EVs as fast as possible. The charging levels of EVs within the distribution network affect the voltage profile of buses of the network. In this paper, an exact Second-Order Cone Programming (SOCP) formulation of the full AC optimal power flow (ACOPF) problem of the distribution network is presented. The network includes solar generation units and EVs as Distributed Energy Resources (DERs). Different charging levels are considered to analyze the impact of EVs on the distribution network. The performance of the proposed model is illustrated for the modified IEEE-33 bus system for different charging levels for EVs. Besides, the impact of available solar power and battery degradation cost of EVs on the distribution network is investigated. It is illustrated that how EV charging will cause voltage deviation challenges for the distribution network.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129189985","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}

Plenty of work has been carried out to investigate the effect of PWM on motor losses and efficiency. In this paper, the focus is to study the impact of PWM on the acoustic noise and vibration performance of a 48-slot 8-pole interior permanent magnet (IPM) machine. The current and radial force harmonics generated due to the PWM effect are identified and the contributions to acoustic noise of the motor are outlined. Results show that the PWM effect on the acoustic noise levels for this motor are negligible since the total sound pressure levels (SPLs) are very similar for sinusoidal and PWM currents for base- and maximum-speed operations. However, the effect on acoustic noise can be significant if introduced PWM harmonics overlap with the stator's natural frequencies to cause resonance, which should be carefully considered during the design process.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126904507","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, ultra-fast charging causes extreme high peak load demand, going beyond the capabilities of current electric utility infrastructure in many location. A high power energy storage system has the ability to off-set such infrastructure power limitations. On top of providing the energy of an EV battery and peak load demands, the decisive metrics for such system are cost of ownership and longevity. The main contribution of this article is to update a previous developed approach to evaluate the economic plausibility of an energy storage system (ESS) solution for EVs ultra-fast charger buffering application. This approach considers the calendar and cycling aging of the energy storage system, the overall efficiency, OPEX, and CAPEX of the ultra-fast charger, but also the purchasing price of the grid electricity. Furthermore, this approach is used to compare the highest longevity lithium battery technology solution, named LTO, to a new super capacitor solution contender, named C-ion. The findings of this study show that both LTO and C-ion technology may represent a cheaper alternative than refueling a gasoline car.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121405695","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 proposed control system manages charging and discharging of an energy storage and regulate two bus voltages at the same time to minimize the number of circuit elements in the system. Since a fuel-cell voltage varies based on the load, a boost converter needs to be employed in the proposed system to provide a 48V DC power to a traction inverter for this light vehicle application. An additional voltage bus which can be higher or lower than the input fuel cell voltage is added for other electric loads. The new dual functional controller is employed for this system to control two different output voltages and manage a battery at the same time. Through the effort of the dual functional control system, one switching element and one inductor can be removed while keeping the same functionality. The proposed dual-functional control strategy and the converter structure are explained in detail first. Then, the feasibility of the converter is verified by experiments.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"29 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126090465","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 development of FCV involves complex architectures and requires an effective virtual testing methodology to improve R&D efficiency. Energetic Macroscopic Representation (EMR) is a graphical formalism to organize models and controls of multidisciplinary systems. It provides the seamless integrations of multi-level models and interconnections between virtual and real testing, which reduces the total development time of the electrified vehicles. Therefore, in this paper, the system-level model of FCV is designed using EMR for the high-fidelity virtual testing of electrified vehicles. An FCV Mobypost that is used for postal delivery in France is chosen as the studied vehicle. The virtual testing results are compared with the real testing. Good consistency is achieved, which validates the performances of the EMR-based FCV model in the virtual testing environment.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133597083","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}

This degradation is generally negligible in the early charge/discharge cycles. An increase in charging/discharging rates (C-rate) applied on a continuous cycling battery reduces its charging time, thereby resulting in a fast charging battery, however, this also escalates the degradation. This degradation can be studied from the resultant decrease in charging/discharging capacities, also termed as capacity fade. To analyze capacity fade, an approach using reference C-rate based charging/discharging capacity analysis is proposed for a time-limited degradation analysis. Further, a step-ahead forecasting approach is proposed for all the charging/discharging capacities' correlated original, and corresponding deviation parameters, to present time-ahead modeling of all the impacted parameters. A combinatorial empirical mode decomposition (EMD)-recurrent wavelet neural network (RWNN) model is proposed as the step-ahead forecasting approach for the correlated parameters. Finally, a comparison of error values between the proposed EMD-RWNN model is performed with combinatorial EMD-wavelet neural network (WNN), standalone WNN and RWNN models to effectively analyze the resulting superior performance of the recurrent nature of the proposed model by forecasting every decomposition.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132131073","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 presented work uses data from driving simulations conducted on Simulation of Urban MObility (SUMO) traffic simulator tool for a low-speed zone, particularly a university campus. A MATLAB/Simulink-based simulation is conducted for the proposed energy management strategy to demonstrate how the system manages the energy flow between the battery and the supercapacitors.
