Plug-in Hybrid Electric Vehicles (PHEVs) are seen to be a step forward in vehicle electrification, to replace ICE based conventional vehicles. Using a PHEV implies that part of the vehicle energy comes from the grid or other sources, such as renewable energy, to charge the battery. However, renewable energy sources being intermittent sources, these new needs would only shift the problem by increasing the number of nuclear and coal power plants, and will not permit solving the problem of pollution or fossil fuel depletion. There is a need to optimize the way, in which the available resources are utilized, in order to reduce dependency on nuclear and coal power plants. This will achieve the overall goal of minimizing pollution, reducing the depletion rate of fossil fuels, as well as reduce the overall cost. This paper proposes a hybrid power system for house energy needs by utilization of renewable energy sources, grid, as well as the PHEV battery source. Emphasis of paper is on optimization of the overall cost of the system, by selecting the most cost effective and feasible option among the available options; namely, renewable energy sources, the grid and the battery of the PHEV. As a prerequisite to the implementation of this scheme, it is desirable to work out an approximate amount of available energy. For this, the efficiencies of the various power converters involved must be determined and taken into account to reduce the energy losses.
插电式混合动力汽车(phev)被认为是汽车电气化的一个进步,将取代基于内燃机的传统汽车。使用插电式混合动力汽车意味着车辆的部分能量来自电网或其他来源,如可再生能源,为电池充电。然而,可再生能源是间歇性的,这些新的需求只会通过增加核电站和燃煤电厂的数量来转移问题,而不会解决污染或化石燃料枯竭的问题。有必要优化现有资源的利用方式,以减少对核能和煤电厂的依赖。这将达到最大限度地减少污染的总体目标,降低化石燃料的消耗率,并降低总体成本。本文提出了一种利用可再生能源、电网和插电式混合动力电池源的家庭能源需求混合动力系统。本文的重点是通过在可选方案中选择最具成本效益和可行性的方案来优化系统的总体成本;即可再生能源,电网和插电式混合动力车的电池。作为实施这一方案的先决条件,最好能计算出大致的可用能量。为此,必须确定并考虑到所涉及的各种功率转换器的效率,以减少能量损失。

Battery electric vehicle (BEV) technology is the most often used type of EV due to its reliable energy storage system. According to the different driving cycles of EVs, electric motors undergo degradation as a result of sudden variations in the dynamic state of torque. Therefore, reliability and performance assessment of the electric motor are important. This paper presents transient and harmonic analysis techniques that were engaged to observe the motor conditions in different operating modes. In order to study the system's behavior, in addition to the harmonic analysis on torque and stator currents, the transient response of stator current for different electric motors is also touched upon in this paper. In an ideal BEV, the motor voltage supplied by the battery is considered to be constant, whereas in real applications, the voltage drops due to the SOC characteristics of the batteries. This paper will also discuss the motor frequency response used to investigate the effects of motor input voltage on the performance of the system. Complete sets of the experimental test is discussed and reported in this study to verify the numerical investigation results.
纯电动汽车(BEV)技术由于其可靠的储能系统而成为最常用的电动汽车类型。根据电动汽车不同的行驶周期,电动机由于转矩动态的突然变化而发生退化。因此,电机的可靠性和性能评估是非常重要的。本文介绍了用于观察不同运行模式下电机状态的暂态和谐波分析技术。为了研究系统的特性,本文除了对转矩和定子电流进行谐波分析外,还对不同电机的定子电流的暂态响应进行了研究。在理想的纯电动汽车中,由电池提供的电机电压被认为是恒定的,而在实际应用中,由于电池的SOC特性,电压会下降。本文还将讨论电机频率响应,用于研究电机输入电压对系统性能的影响。本文讨论并报道了完整的试验结果,以验证数值研究结果。

In this paper, possible efficiency improvements of electric components used in drivetrain technologies for passenger vehicles are examined. The fuel consumption is determined for drivetrains with various degrees of electrification, combined with a set of combustion engine technologies. The simulations underline the importance of the energy efficiency of the electric drivetrain to obtain low CO2 emissions. The results help in deciding for which components the research has to focus on regarding efficiency improvements. A large sensitivity to total energy efficiency is observed for the electric motor, battery and power electronics efficiencies.

This paper presents a control solution based on dynamic disturbance decoupling control (DDC) for the implementation of an ultra high speed centrifugal compressor for the air management of fuel cell systems. Unlike other displacement compressors, centrifugal compressor has strong coupling between speed, mass flow and pressure, which gives difficulty for its implementation and limits its operation region. In this paper, a unique dynamic disturbance decoupling control strategy, based on the active disturbance rejection control (ADRC) framework, is developed. The simulation results show that it is a great fit for the highly nonlinear and multivariable centrifugal compression system.

This paper proposes a hybrid battery model-based high-fidelity state of charge (SOC) and electrical impedance estimation method for multicell lithium-ion batteries. The hybrid battery model consists of an enhanced Coulomb counting algorithm for SOC estimation and an electrical circuit battery model. A particle swarm optimization (PSO)-based online parameter identification algorithm is designed to estimate the electrical parameters of the cells sequentially. An SOC compensator is designed to correct the errors of the enhanced Coulomb counting SOC estimations for the cells sequentially. This leads to an accurate, robust online SOC estimation for individual cells of a battery pack. The proposed method is validated by simulation and experimental data collected from a battery tester for a four-cell polymer lithium-ion battery pack. The proposed method is applicable to other types of electrochemical batteries.

This paper proposes a novel Electric-Hydraulic Hybrid (EH2) drivetrain for Electric vehicles (EVs) and Plug-in hybrid electric vehicles (PHEVs). In the proposed energy storage system, a hydraulic accumulator is employed to utilize its high power density. It can accept high frequencies of charging and discharging, making it more promising for industrial and automotive use in regenerative braking. Therefore, this technology is highly suitable for passenger cars, sport-racing vehicles, express cars and trucks in cities.

This paper describes the modelling of the system poly-phase motor and multi-leg converter during normal and under fault conditions. The numerical simulation of the Direct Torque Control (DTC) applied to the five-phase asynchronous machine is presented. In the DTC method, the torque and the flux are imposed directly by a choice discriminating of the vector voltage imposed by the five-leg converter. Our objective is to achieve an effective control as well in permanent regime as in transient one using the combination of different strategies of commutation, to elaborate the most optimal working condition based on the mathematical reports of the special vectors; stator and rotor flux, and stators current and voltage. The implantation of the DTC is conceived on the basis of an algorithm of evaluation of the stator flux and the electromagnetic torque. Both normal and under fault conditions are simulated. Under fault conditions, resulting in loss of one or more phases consecutively, still the machine works with its desirable performance. Most poly-phases machines are used in propulsion maritime, aerospace, naval, railway traction, and in too many applications where the repartition of power is needed. To illustrate the performances of this technique, results by numeric simulation on MATLAB are presented.

Modeling is going to play a crucial role for utilities as Electric Vehicle (EV) ownership percentage increases. Utilities anticipate new demand peaks due to EV charging loads, particularly at high penetration levels. Several efforts in the utility industry have been using a demographic approach to find potentially worst overloaded distribution infrastructure and use these locations as test beds. This paper will demonstrate the methodology used in the demographics study to identify areas of interest for urban New Mexico feeders. Using existing infrastructure with real utility GIS data, several leading modeling tools were used to identify possible long-term and short-term outcomes. Using the demographic results, system- and component-specific analysis, an impact study will identify potential impacts and mitigation opportunities. The impact analysis methodology described in this paper will identify short term and long term impacts on voltage issues, protection, Power Quality, Loading, and Control. Through modeling results, data integrity gaps, generic to other utilities can also be identified. Other methods of modeling described in this paper will use Synergee (modeling tool developed by GL Group) as a baseline to simulate the EV penetration and correlate that with other Distributed Energy Resources such as PV. General conclusions will be made based on the results of the impact study. The conclusions will be used to identify business-case opportunities such as DR, TOU and possibly V2G. The modeling efforts will also support and identify gaps in modeling software in the utility and data integrity to have real time data for distribution planning for short term and long term impacts of all DERs.
随着电动汽车(EV)拥有率的增加,建模将在公用事业中发挥至关重要的作用。公用事业公司预计,由于电动汽车充电负荷,特别是在高渗透率水平下,将出现新的需求高峰。公用事业行业的一些努力一直在使用人口统计学方法来寻找潜在的最严重超载的配电基础设施,并将这些地点用作试验台。本文将展示在人口统计学研究中使用的方法,以确定新墨西哥州城市喂食者感兴趣的领域。利用现有基础设施和实际实用GIS数据,使用了几种领先的建模工具来确定可能的长期和短期结果。利用人口统计结果、针对系统和组件的分析,一项影响研究将确定潜在影响和缓解机会。本文中描述的影响分析方法将确定对电压问题、保护、电能质量、负载和控制的短期和长期影响。通过建模结果,还可以识别出数据完整性差距、通用到其他实用程序。本文中描述的其他建模方法将使用synergy (GL Group开发的建模工具)作为基线来模拟电动汽车的渗透率,并将其与光伏等其他分布式能源相关联。将根据影响研究的结果作出一般性结论。结论将用于确定商业案例机会,如DR, TOU和可能的V2G。建模工作还将支持和识别公用事业和数据完整性建模软件中的差距,以便为所有der的短期和长期影响的分配规划提供实时数据。

This paper will demonstrate the methodology used in the demographics study to identify areas of interest for urban New Mexico feeders. Using existing infrastructure with real utility GIS data, several leading modeling tools were used to identify possible long-term and short-term outcomes. Using the demographic results, system- and component-specific analysis, an impact study will identify potential impacts and mitigation opportunities. The impact analysis methodology described in this paper will identify short term and long term impacts on voltage issues, protection, Power Quality, Loading, and Control. Through modeling results, data integrity gaps, generic to other utilities can also be identified. Other methods of modeling described in this paper will use Synergee (modeling tool developed by GL Group) as a baseline to simulate the EV penetration and correlate that with other Distributed Energy Resources such as PV. General conclusions will be made based on the results of the impact study. The conclusions will be used to identify business-case opportunities such as DR, TOU and possibly V2G. The modeling efforts will also support and identify gaps in modeling software in the utility and data integrity to have real time data for distribution planning for short term and long term impacts of all DERs.","PeriodicalId":118616,"journal":{"name":"2013 IEEE Transportation Electrification Conference and Expo (ITEC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122234185","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}
