Research in Machine Learning (ML) has developed techniques and systems that parallelize Deep Learning (DL) training over numerous devices or compute nodes as the pace of innovation in these domains has quickened recently. Many systems have failed to deliver overall performance on a variety of DL models as the models' structural complexity increases. Particularly, the knowledge and time needed to map from a suitable distribution strategy to the model are frequently underestimated when it comes to ML scale-up. More specifically, when Autonomous and Connected Vehicles (CAVs) are used as dew devices in cloud-dew computing systems and are planning a safe route in specific road circumstances. Applying parallel training systems to complicated models leads to lower-than-expected performance and nontrivial development overheads in addition to model prototyping. This article identifies and addresses research difficulties in both usability and performance in parallel ML approaches and system implementations, when a CAV generates the dataset for path planning and communicates it on the cloud-dew network, we use a hybrid DL model that uses an LSTM-AE built-in a cyber-attacks detection system. We emulate the situation of numerous CAV s using the same data profile for motion planning on the same road environment. We examine the configuration in a distributed architecture employing synchronous data parallelism, which enables an optimized speedup and improved training runtime by comparing various processing units.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123268336","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 capability has the potential to provide even more energy savings when considered in the speed planning stage of Autonomous Electric Vehicles (AEVs). The RB process, however, suffers from low-speed limitation which can have adverse effects on energy recuperation at low speeds. This paper presents a comparison of two approaches that use fixed and dynamic low-speed boundaries (LSBs) to address RB limitation at low speeds and studies the impact of each approach on the eco-driving control problem for AEVs. The eco-driving problem is executed with Mixed Integer Linear Programming (MILP), and two different case studies associated with the operation of RB at low speeds are analyzed for a predetermined signalized route. It is shown that up to 3.9% increase in energy harvesting is achievable by employing dynamic LSB. The results of this study further illustrate the importance of considering a dynamic RB boundary when it comes to solving the eco-driving problem for AEVs.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123495146","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}

Cascaded H-bridge (CHB) is used as the active front-end rectifier and dual active bridges (DABs) are utilized for DC-DC conversion and isolation. One issue with this topology is the unbalance of the DC-link voltages during unequal loading. Another issue is the large size of DC link capacitors required to decouple the second-harmonic ripple power introduced from the AC grid. To address these two issues, an AC link Solid State Transformer (SST) topology and its control are proposed in this paper. The AC link is constructed by using a three-winding transformer in the DAB converter wherein the third winding of all the converters are connected in parallel. The AC link enables flow of circulating power among the H-bridges in all the three phases and eliminates the issue of voltage unbalance even in 100 % unbalanced loading conditions. The magnetic flux associated with the second harmonic ripple is also cancelled in the AC link due to three phase symmetry and hence the DC link capacitor size is drastically reduced. Simulation results are presented to verify the claims.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123823427","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 usage of single-layer wound coils is possible in this topology, and by using this type of winding it is possible to implement advanced in-slot cooling systems.

The PWM effects are studied on a Surface Permanent Magnet Synchronous Motor (SPMSM) of 150 kW, 20000 rpm designed for an aerospace application. A 3D-Finite Element Model (FEM) of the machine is used for analysis in JMAG software. First, the machine model is studied for various electromagnetic losses using an ideal sinusoidal current waveform. These losses are used to study the thermal characteristics of the machine using Motor-CAD. The PWM currents are generated by modelling the motor drive with a 3-Level Active Neutral Point Clamped (ANPC) converter controlled by Field Oriented Control (FOC) algorithm in PSIM software. The machine losses are analyzed in FEM software by feeding the PWM current thus obtained. Using the thermal model of the machine developed in Motor-CAD, the thermal characteristics are studied. The switching frequency of the inverter is varied over a range of values to investigate its effect on the losses and thermal characteristics. Thus, this paper presents the effect of PWM current ripples on the electromagnetic losses and thermal characteristics of a high-speed machine.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126289188","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}

Within this paper, a reverse auction is formulated through an optimization problem to minimize the utility energy cost using Vehicle-to-Grid (V2G) operation, as well as transition residential communities to dispatchable aggregate constant load profiles for demand response (DR). The evolution-ary V2G Auction (eV2GA), including the non-dominated sorting genetic algorithm (NSGA-II), is proposed for the formulated problem. It uses co-simulation with OpenDSS for power flow analysis as part of the objective function to account for physical constraints of infrastructure on the cost analysis. The results are verified against a greedy method in two case studies on the IEEE 123 test feeder with modified residential load showing over 20 % reduction in cost from no v2G. It is demonstrated that physical power system constraints, such as line active power flow limits, may be implemented into the optimization through the proposed approach and do affect the V2G design solution by placing influence on location of the selected EV s in the distribution system.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"646 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116840307","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 battery capacity estimation is essential to determine diagnostic details on the battery and in determining several other battery parameters. Past research has shown that a normalized open-circuit voltage characterization independent of temperature is also dependent on accurate capacity estimation. In most works, the normalized OCV characterization approaches were done at C/30 rates where the entire data collection took approximately 60 hours. The undesirably long data collection process motivated the need to determine the expected accuracy at lower C-rates in realistic conditions. However, little attention was paid in the literature to investigate capacity estimation error at various C-rates. Thus, in this paper, the battery capacity estimation is repeated at seven C-rates: C/2, C/4, C/8, C/16, C/32, C/64 and C/128, to compare their accuracy using data collected from a laboratory-based battery cycler. It was found that with a lower current rate, a maximum of 0.3 Ah error is observed in the charge capacity. An error of 0.16 Ah was observed for the discharge capacity at the lowest C-rate of C/2 A.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121663209","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}
