Digital Twin Modeling of a Solar Car Based on the Hybrid Model Method with Data-Driven and Mechanistic
applied sciences Article Digital Twin Modeling of a Solar Car Based on the Hybrid Model Method with Data-Driven and Mechanistic Luchang Bai, Youtong Zhang *, Hongqian Wei , Junbo Dong and Wei Tian Laboratory of Low Emission Vehicle, Beijing Institute of Technology, Beijing 100081, China; [email protected] (L.B.); [email protected] (H.W.); [email protected] (J.D.); [email protected] (W.T.) * Correspondence: [email protected] Featured Application: This technology is expected to be used in energy management of new energy vehicles. Abstract: Solar cars are energy-sensitive and affected by many factors. In order to achieve optimal energy management of solar cars, it is necessary to comprehensively characterize the energy flow of vehicular components. To model these components which are hard to formulate, this study stimulates a solar car with the digital twin (DT) technology to accurately characterize energy. Based on the hybrid modeling approach combining mechanistic and data-driven technologies, the DT model of a solar car is established with a designed cloud platform server based on Transmission Control Protocol (TCP) to realize data interaction between physical and virtual entities. The DT model is further modified by the offline optimization data of drive motors, and the energy consumption is evaluated with the DT system in the real-world experiment. Specifically, the energy consumption Citation: Bai, L.; Zhang, Y.; Wei, H.; error between the experiment and simulation is less than 5.17%, which suggests that the established Dong, J.; Tian, W. Digital Twin DT model can accurately stimulate energy consumption. Generally, this study lays the foundation Modeling of a Solar Car Based on the for subsequent performance optimization research. -
ISU Speed Skating Season 2019/20
November 12, 2019 Lausanne, Switzerland The 2019/20 season will be one for the fast and the furious In 2019/20 Speed Skating will be faster than it has ever been. The season builds up to a climax at the ISU World Single Distances Speed Skating Championships on the fastest ice on earth in Salt Lake City in February. The six world records during last season's ISU World Cup Speed Skating finals at the Utah Olympic Oval, were just a prelude to what's yet to come. The 2019/20 season also has a couple of novelties in store. Milwaukee, USA, will host the first ever ISU Four Continents Championships in Speed Skating, Hamar will be home to the first ever combined ISU World Allround and ISU World Sprint Speed Skating Championships, and at the ISU World Cup Speed Skating Final in Heerenveen there will be a first ever mixed gender relay as demonstration event. The Junior Speed Skaters are looking forward to the 2020 Winter Youth Olympic Games in Lausanne in January. Early season form The season kicks-off with the first of six legs in the ISU World Cup Speed Skating in Minsk, Belarus, on November 15-17. Most skaters have already skated competitively beforehand, however. ISU World Allround Speed Skating champion Patrick Roest (NED) showed early season form when he broke the track record in the men's 10,000m (12:42.97) at the Dutch World Cup trials in Heerenveen on November 3. 1000m ISU World Speed Skating Champion Kai Verbij (NED) also impressed with a track record in the 1000m (1:07.48). -
Solar Racking Installation for ATN Final Report Fall 2016
1 Solar Racking Installation for an Automated Public Transportation System Solar Engineering Team San Jose State University Mechanical Engineering Department August, 2016 Advisor: Dr. Burford Furman Ron Swenson Eric Hagstrom Eric Rosenfeld Author: 2 Abstract The Sustainable Mobility System for Silicon Valley (SMSSV), also known as the Spartan Superway, is a project to develop a grid-tied solar powered Automated Transit Network (ATN) system. The ATN system will be elevated allowing for traffic and infrastructure below. The ATN system is designed for the vehicles or pods to be hanging from the track, giving the system opportunities for a solar module system on the top of the ATN. Recent work has focused on analyzing the power requirements and designing the solar power system for a potential implementation of ATN in the city of San José. The System Advisor Model (SAM) software from the National Renewable Laboratory (NREL) estimates the POA (plane-of-array) energy available for the ATN network and how much can be used for other applications. Results show to power 88 vehicles over a 14km guideway 24 hours a day requires 19,600 monocrystalline solar panels with an area of 38,000m2. 24/7 and be zero net-metered (on average) over a calendar year. Extensive research determining the boundary condition required for our solar racking system is underway. A design for a racking system utilizing bolts was analyzed showing more 3 difficult maintenance & installation, however cheaper infrastructure. Another design for a semi- automated design was analyzed essentially showing cheaper maintenance & installation, however more expensive infrastructure. Four different designs for semi-automated locking mechanism were created. -
Designing a Concentrating Photovoltaic (CPV) System in Adjunct with a Silicon Photovoltaic Panel for a Solar Competition Car
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Repositorio Institucional Universidad EAFIT Designing a Concentrating Photovoltaic (CPV) system in adjunct with a silicon photovoltaic panel for a solar competition car Andrés Arias-Rosalesa, Jorge Barrera-Velásqueza, Gilberto Osorio-Gómez*a, Ricardo Mejía- Gutiérreza a Design Engineering Research Group (GRID), Universidad EAFIT, Medellin, Colombia * Corresponding author: [email protected], Other authors’ e-mail: [email protected]; [email protected]; [email protected] ABSTRACT Solar competition cars are a very interesting research laboratory for the development of new technologies heading to their further implementation in either commercial passenger vehicles or related applications. Besides, worldwide competitions allow the spreading of such ideas where the best and experienced teams bet on innovation and leading edge technologies, in order to develop more efficient vehicles. In these vehicles, some aspects generally make the difference such as aerodynamics, shape, weight, wheels and the main solar panels. Therefore, seeking to innovate in a competitive advantage, the first Colombian solar vehicle “Primavera”, competitor at the World Solar Challenge (WSC)-2013, has implemented the usage of a Concentrating Photovoltaic (CPV) system as a complementary solar energy module to the common silicon photovoltaic panel. By harvesting sunlight with concentrating optical devices, CPVs are capable of maximizing the allowable photovoltaic area. However, the entire CPV system weight must be less harmful than the benefit of the extra electric energy generated, which in adjunct with added manufacture and design complexity, has intervened in the fact that CPVs had never been implemented in a solar car in such a scale as the one described in this work. -

TOWN of PETERBOROUGH Photovoltaic Project Proposal
Application to the New Hampshire Public Utilities Commission June 2013 TOWN OF PETERBOROUGH Photovoltaic Project Proposal 6/7/2013 Letter of Transmittal Borrego Solar, with its NH headquarters in Peterborough, NH, has teamed up with the Town of Peterborough to develop a 947kW ground mounted PV array to be located at the Peterborough Waste Water Treatment Facility (WWTF). The NH PUC has clearly stated that two of the most important selection criteria factors are the project’s likelihood to expand the production capacity of renewable energy facilities in NH (including REC qualification) and the capacity of the team to successfully complete the initiative. After reading our proposal we hope you will share our belief that our team is extremely qualified and has the experience and expertise to complete this project. This solar project will be a class I REC producing site, generating an estimated 1,150 REC’s in the first year. Borrego Solar has provided a detailed production estimate using the industry standard PVSyst software. Borrego Solar has essentially written the book on production estimating – see SolarPro article – Exhibit E. Our fleet of systems has historically produced at 103% of estimated production, and we will have a production guarantee in our PPA with the Town of Peterborough. That guarantee includes damages should the system under-perform, which ensures our commitment to hitting the annual production estimates. The Town of Peterborough has recently completed a state of the art WWTF at 58 Water Street. The new facility eliminates the need to have several acres of holding ponds. The waste from the ponds will be removed, and the ponds will be filled in. -
This Season Combines the New and The
November 13, 2018 Lausanne, Switzerland This season combines the new and the old After the exciting PyeongChang 2018 Olympic Winter Games last February, a new generation of long track Speed Skaters is gearing up to challenge the reigning champions in the next Olympiad. The 2018/19 season has a lot of variety to offer: outdoor ISU European Speed Skating Championships in Collalbo, ISU World Single Distances Speed Skating Championships at the Max Aicher Arena in German Inzell, ISU World Sprint Speed Skating Championships in Dutch Speed Skating Mekka Heerenveen, and a North American season climax with ISU World Allround Speed Skating Championships in Calgary and ISU World Cup Speed Skating final in Salt Lake City. Kramer chases 10th European and World Allround titles Since 2017 the format of the ISU European Speed Skating Championships alternates and last year saw the inaugural European Championships with a single distances format. This season the Championships will be Allround and will be held in Collalbo. The Italian town has hosted the European Allround Championships twice in the past, first in 2007, when 21-year-old Dutchman Sven Kramer won his first European title. In 2019 he will be aiming at his tenth European Allround title. The World Single Distances Championships will visit Inzell for the second time in history. The first time, in 2005, the Championships were held at the outdoor Ludwig Schwabl Stadion, which was roofed in to become the Max Aicher Arena in 2011. Olympic 500-meter champion Håvard Holmefjord Lorentzen (NOR) and Olympic 1000-meter champion Jorien ter Mors (NED) will defend their 2018 World Sprint titles in Heerenveen, which hosts the World Sprint Championships for the sixth time. -
