  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. Optimization modeling of frequency reserves and inertia in the transition to a climate-neutral electricity system

    Författare :Jonathan Ullmark; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; generation expansion planning; frequency reserves; inertia; Energy system modeling; synthetic inertia; frequency control;

    Sammanfattning : The ongoing transition towards electricity production systems that are dominated by wind and solar power challenge both the traditional strategy for meeting a varying electricity demand and the traditional way of controlling the AC frequency of the electricity grid. This work investigates how frequency reserves (FR) and inertia, as well as inter-hourly variation management interact in the transition to a climate-neutral electricity system. LÄS MER

  5. 4. Optimization of empty freight car distribution in scheduled railways

    Författare :Martin Joborn; Warren B. Powell; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In a railway system, empty freight cars have to be repositioned to enable transportation demand to be fulfllled. These empty car movements are planned and implemented in the empty freight car distribution process. LÄS MER

  7. 5. Prediction-driven approaches to discrete choicemodels with application to forecasting car typedemand

    Författare :Shiva Habibi; Anders Karlström; Stefan Mabit; KTH; []
    Nyckelord :Transportvetenskap; Transport Science;

    Sammanfattning : Models that can predict consumer choices are essential technical support fordecision makers in many contexts. The focus of this thesis is to address predictionproblems in discrete choice models and to develop methods to increase the predictivepower of these models with application to car type choice. LÄS MER
