1. 21. From Passive to Active Electric Distribution Networks

   Författare :Javier Campillo; Erik Dahlquist; Wu Jianzhong; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active distribution networks; smart grids; smart Meters; real-time pricing; demand-side management; electric vehicles; power systems; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Large penetration of distributed generation from variable renewable energy sources, increased consumption flexibility on the demand side and the electrification of transportation pose great challenges to existing and future electric distribution networks. This thesis studies the roles of several actors involved in electric distribution systems through electricity consumption data analysis and simulation models. LÄS MER

3. 22. Transportation Mission Based Optimization of Heavy Vehicle Fleets including Propulsion Tailoring

   Författare :Toheed Ghandriz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; heterogeneous heavy vehicle fleet; optimal energy management; propulsion system tailoring; Automated Driving Systems; electrified propulsion; total cost of ownership; electromobility; transportation mission; fleet sizing;

   Sammanfattning : Over decades freight vehicles were produced for a wide range of operational domains so that vehicle-manufacturers were not concerned much about the actual use-cases of the vehicles. Environmental issues, costumer expectations along with growing demand on freight transport created a competitive environment in providing better transportation solutions. LÄS MER

4. 23. Modelling and Appraisal in Congested Transport Networks

   Författare :Jens West; Maria Börjesson; Oded Cats; Leonid Engelsson; Giulio Cantarella; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport modelling; Transit Assignment; Appraisal; Congestion; Crowding; Cost-benefit analysis; Value of time; Congestion charge; Dynamic traffic assignment; Transportvetenskap; Transport Science;

   Sammanfattning : Appraisal methodologies for congestion mitigation projects are relatively less well developed compared to methodologies for projects reducing free flow travel times. For instance, static assignment models are incapable of representing the build-up and dissipation of traffic queues, or capturing the experienced crowding caused by uneven on-board passenger loads.

5. 24. Metadata Management in Multi-Grids and Multi-Clouds

   Författare :Daniel Espling; Erik Elmroth; Erwin Laure; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; grid computing; cloud computing; accounting; billing; metadata; monitoring; structure; fairshare; scheduling; federated; Computer Science; datalogi;

   Sammanfattning : Grid computing and cloud computing are two related paradigms used to access and use vast amounts of computational resources. The resources are often owned and managed by a third party, relieving the users from the costs and burdens of acquiring and managing a considerably large infrastructure themselves. LÄS MER

7. 25. Optimal Powertrain Dimensioning and Potential Assessment of Hybrid Electric Vehicles

   Författare :Nikolce Murgovski; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; powertrain sizing; plug-in slide-in HEV; Dynamic Programming; convex optimization; Hybrid electric vehicle; power management;

   Sammanfattning : Hybrid electric vehicles (HEVs), compared to conventional vehicles, complement the traditional combustion engine with one, or several electric motors and an energy buffer, typically a battery and/or an ultracapacitor. This gives the vehicle an additional degree of freedom that allows for a more efficient operation, by e.g. LÄS MER
