1. 1. Infrastructural requirements for indirect and direct electrification of road transportation

   Författare :Therese Lundblad; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogen supply; electric vehicles; hosting capacity; low-voltage grid; home charging; hydrogen infrastructure; charging strategies;

   Sammanfattning : This thesis analyzes the integration of electricity and transportation systems for a future in which transportation is increasingly electrified. The focus is on exploring the infrastructures required for the indirect electrification of heavy transportation and the direct electrification of passenger vehicles. LÄS MER

3. 2. Electric Vehicle Charging Modeling

   Författare :Pia Grahn; Lennart Söder; Ola Carlsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : With an electrified passenger transportation fleet, carbon dioxide emissions could be reduced significantly depending on the electric power production mix. Increased electric power consumption due to electric vehicle charging demands of electric vehicle fleets may be met by increased amount of renewable power production in the electrical systems.

4. 3. Evaluation and variability of power grid hosting capacity for electric vehicles : Case studies of residential areas in Sweden

   Författare :Maria Sandström; Erik Dotzauer; Chris Bales; Pei Huang; Björn Laumert; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hosting capacity HC ; Power grid; Electric vehicle EV ; Charging strategies; Power flow simulations; Uncertainty analysis; Hållbar stadsutveckling; Sustainable Urban Development; inget Strategiskt forskningsområde SFO ; no Strategic Research Area SFO ;

   Sammanfattning : Electric vehicles (EVs) are increasing in popularity and play an important role in decarbonizing the transport sector. However, a growing EV fleet can cause problems for power grids as the grids are not initially designed for EV charging. The potential of a power grid to accommodate EV loads can be assessed through hosting capacity (HC) analysis. LÄS MER

5. 4. Electric Vehicle Charging Impact on Load Profile

   Författare :Pia Grahn; Lennart Söder; Ola Carlsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : One barrier to sustainable development is considered to be greenhouse gas emissions and pollution caused by transport, why climate targets are set around the globe to reduce these emissions. Electric vehicles (EVs), may be a sustainable alternative to internal combustion engine vehicles since having EVs in the car park creates an opportunity to reduce greenhouse gas emissions. LÄS MER

7. 5. High Power Radio Frequency Solid-State Amplifiers and Combiners for Particle Accelerators : From module to system design approach

   Författare :Long Hoang; Dragos Dancila; Paul Tasker; Uppsala universitet; []
   Nyckelord :solid state technology; power amplifier; superconducting cavities; optimal charging; high efficiency; particle accelerators; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

   Sammanfattning : The rise of Big Science projects brings issues related to the energy consumption and the associated environmental impacts of such large-scale facilities. Therefore, environmentally-sustainable developments are undertaken towards the adoption of energy savings and improved energy-efficient approaches. LÄS MER
