In electric bus drivetrains, energy management strategy can be utilized to optimize operation of auxiliary systems, charging systems, and the operation of the electric powertrain. The electric powertrain is composed of several components linked in series, each having their own optimum band of operation. The paper studies various strategies to actuate the electric motor complemented with appropriate gearbox ratios to maximize the efficiency of the propulsion energy transmission, maintain vehicle speed and acceleration constraints, and electric motor angular speed and torque constraints. This paper also proposes an ECO friendly velocity profile based on smooth velocity changes, and limitations in top speed and acceleration to reduce energy consumption and using regenerative braking to recover energy. Results show that bang-bang actuation styles have less optimal energy utilization; however, maximum power actuation style can recover the most energy from braking.","PeriodicalId":166751,"journal":{"name":"2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127965316","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}

Besides affecting mobility patterns, autonomous driving will open new perspectives in terms of interactions with the power grid. This paper explores the potential of autonomous EVs of reducing grid congestions thanks to the possibility of reaching the most suitable recharging locations autonomously. We first develop an algorithm for the coordinated charging of non-autonomous EVs accounting for grid constraints. We then augment its formulation by modeling the charging locations as decision variables of the problem, adopting an efficient linear mixed-integer program based on a linearized grid model and McCormick (exact) relaxations to handle some bi-linear terms appearing in the formulation. Considering the CIGRE' benchmark system for LV residential grids, we compare non-autonomous versus autonomous EVs and show that the additional degree of freedom coming from autonomous driving achieves reducing grid congestions.","PeriodicalId":166751,"journal":{"name":"2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114152386","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}

Nevertheless, the ageing response of WBG-based converters in the EVs throughout a complete mission-profile has remained a significant concern for Automotive Original Equipment Manufacturers (OEMs). This paper presents a reliability assessment of a WBG-based Interleaved Bidirectional high-voltage (HV) DC/DC Converter (IBC) for EV-drivetrains. The reliability of IBC is assessed stepwise using a standard mission-profile based on a reliability estimation toolchain that simulates the thermal wear-out of failure-prone components like the semiconductor’s module and DC-link electrolytic capacitor. A modified rainflow algorithm is used to count the thermal stress, swings and expansion of the active and passive components on the IBC system. Outcomes of this article depict that the DC-link capacitor and the upper MOSFET of the half-bridge module are the most failure-prone components when the EV is driven using the dynamic WLTC mission-profile. Moreover, experimental results have presented the accuracy of the electro-thermal modelling by operating 30kW IBC prototype at different load conditions.","PeriodicalId":166751,"journal":{"name":"2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123732322","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 subtropical and hot-humid climates, typically cooling is required in buildings year round to maintain a comfortable indoor environment. The reduction of energy consumption, in turn, reducing the production of greenhouse gases can be achieved through effective operation of the built environment. In order to move forward with the mitigation of climate change, the impacts of rapid urbanisation need to be-offset. Eco-roofs are one way to achieve this. The aim of this study is to report the energy and cost savings, and achieving environmental benefits of the implementation of eco-roofs in subtropical climates. Eco-roofs use plants to improve roofs performance, appearance or both. They fall into two main categories, which are intensive and extensive green roofs. In this study, an extensive rooftop greenery setup was used for experimental data collection and comparison with non-green roofs setup in a subtropical and hot-humid climate. From the experimental data, it was found that the eco-roofs reduced the cooling load by approximately 13.5% in such climate.","PeriodicalId":166751,"journal":{"name":"2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114256948","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}

An affordable and grid-quality supply of energy can open new possibilities for socioeconomic progress. As part of a joint project between South Africa’s Eastern Cape province and Germany’s state of Lower Saxony a Photovoltaic (PV) hybrid mini-grid is developed in the municipality of Upper Blinkwater in Eastern Cape for a rural community of 70 households with 90% living off of social grants and no access to the main national grid. The aim of this work is to develop a smart Monitoring and Evaluation Framework (MEF) for hybrid renewable mini-grids by integrating cutting-edge technologies in a scalable platform of replicable solutions towards connecting the mini-grid with diverse stakeholders with enhanced observability of both generation and consumption profiles. The MEF provides the opportunity to streamline the flow of real-time energy data (generation, consumption, and storage) from the system to generate accurate and high-resolution data-driven load profiles for rural households. Simultaneously, the interrelation between energy access and social development will be studied and analyzed.","PeriodicalId":166751,"journal":{"name":"2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114867755","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}

It is demonstrated that the Power- and Current-Based Control strategies present distinct operational features in relation to classic droop control, mostly concerning how active and reactive power are shared among inverters. Additionally, it is shown how the strategies differ in steady-state operation and response time while comparing to classic droop-based methods. Discussions are presented based on simulation results using Matlab/Simulink, comprising two distributed inverters in a low-voltage microgrid and considering different operational scenarios, such as load changes, existence of linear and nonlinear loads, as well as line impedance variations.

However, electrification leads to a change in the vehicle as we know it from the last decades. The small machine and the big and heavy energy storage challenge manufacturers in developing cars with similar properties like internal combustion vehicles. Therefore, engineers use virtual tools to find optimal solutions in terms of package, performance, and efficiency in the very early stage of the development process. One of those tools is the longitudinal dynamic simulation that is used for sizing the battery and powertrain. In this paper, the authors present a longitudinal dynamic simulation with a low computing time, which helps the user to estimate acceleration, maximum speed, and energy consumption of a full-electric vehicle. The efficiency diagrams for the electric machines are computed by an electric machine design tool instead of scaling one diagram. Both the longitudinal simulation and the efficiency diagrams tools will be provided open source to make it usable for the scientific community and improve it over time.","PeriodicalId":166751,"journal":{"name":"2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121561877","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}

Condition monitoring technique is a common approach for evaluating switch health by analyzing the changing trend of some specific switch parameters. Due to the basic differences between wide bandgap-based and silicon-based power modules, applying the existing condition monitoring approaches does not lead to the expected accuracy in circuits using wide bandgap devices. Considering the existing limitations in electrical parameters-based condition monitoring approaches, a multiphysics condition monitoring technique is proposed in this paper. Complete profiles of switch operational parameters have been employed in an iterative process in order to obtain junction temperature of the switch as the main failure indicator. The effect of thermal, electrical, and magnetic physics are considered to have a more accurate junction temperature assessment. Weibull-Arrhenius lifetime model is employed to assess the switch lifetime based on the real-time switch parameters. The proposed multiphysics condition monitoring approach is simulated for a case study of electric vehicle application (Toyota Prius 2010 DC/DC converter system). In the developed simulation platform, COMSOL, PLECS, and MATLAB are employed as the thermal and magnetic analyzer, circuit analyzer, and reliability assessment center respectively.","PeriodicalId":166751,"journal":{"name":"2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125144723","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}
