  2. 1. Congestion Charging in Urban Networks : Modelling Issues and Simulated Effects

    Author : Ida Kristoffersson; Leonid Engelson; Otto Anker Nielsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport Modelling; Congestion Charging; Departure Time Choice; Dynamic Traffic Simulation; Welfare Effects; Equity;

    Abstract : One of the major challenges cities face today, in their development towards sustainable urban areas, is the need for an efficient and environmentally friendly transport system. This transport system should manage to tie together the city without strong adverse impact on urban environment, air-quality and climate change. READ MORE

    Abstract : Engine modeling and simulation have been necessary tools for efficient product development in the automotive industry for some time. The scope of this work is novel engine models, tools, and methods for powertrain research and development. READ MORE

  5. 3. Electric Vehicle Charging Modeling

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

    Abstract : 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.

  6. 4. Multiple Aspects of Dynamic Rating in the Power System

    Author : Seyede Fatemeh Hajeforosh; Math Bollen; Sarah Rönnberg; Alfredo Vaccaro; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic rating; Transmission lines; Overload Protection; Stochastic analysis; Hosting capacity; Transformers; Electric Power Engineering; Elkraftteknik;

    Abstract : Increased consumption and increased use of renewable energy make overhead lines and transformers more often congested. Dynamic rating (DR) uses a time-depending maximum permissible current instead of a long-term-fixed rating; it is an effective solution to upgrade the capacity of existing grid assets to minimize this congestion.

  7. 5. Modeling, Optimization and Analysis of Electromobility Systems

    Author : Gabriel Domingues; Industriell elektroteknik och automation; []
    Keywords : Electromobility; Electric Vehicles; Hybrid Vehicles; Charging; Modeling; Optimization;

    Abstract : Due to an increase in environmental awareness and an improved understanding on the impact of human activity on our planet’s climate, there is a strong desire both from governments and the general public to reduce harmful pollution and emissions. This requires action on different fronts, like decarbonizing electricity generation, industrial activity and not least the transport sector. READ MORE
