  1. 1. Designing Urban Road Congestion Charging Systems : Models and Heuristic Solution Approaches

    Författare :Joakim Ekström; Jan Lundgren; Anders Karlström; Linköpings universitet; []
    Nyckelord :transport modeling; congestion pricing; network design; bi-level optimization; toll locations; traffic assignment; user equilibrium; collection cost; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The question of how to design a congestion pricing scheme is difficult to answer and involves a number of complex decisions. This thesis is devoted to the quantitative parts of designing a congestion pricing scheme with link tolls in an urban car traffic network. LÄS MER

  3. 2. Benefits of Coordinating Plug-In Electric Vehicles in Electric Power Systems : Through Market Prices and Use-of-System Network Charges

    Författare :Ilan Momber; Lennart Söder; Tomás Gómez San Román; José Villar Collado; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicles; Power Systems; Optimization; Elektrische Voertuigen; Energiesystemen; Optimalisatie; Elbilarna; Elkraftsystem; Optimering; Vehiculos Electricos; Sistemas de Potencia; Optimización; Electrical Engineering; Elektro- och systemteknik; Economics; Nationalekonomi; Industriell ekonomi och organisation; Industrial Engineering and Management; Energy Technology; Energiteknik; Transportvetenskap; Transport Science;

    Sammanfattning : Both electric power systems and the transportation sector are essential constituents to modern life, enhancing social welfare, enabling economic prosperity and ultimately providing well-being to the people. However, to mitigate adverse climatological effects of emitting greenhouse gases, a rigorous de-carbonization of both industries has been set on the political agenda in many parts of the world.

  4. 3. Simulation-Based Optimization of a Series Hydraulic Hybrid Vehicle

    Författare :Katharina Baer; Petter Krus; Liselott Ericson; Seppo Tikkanen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Hybrid transmissions are characterized by their utilization of more than one form of energy storage. They have the potential to help reduce overall fuel consumption and vehicle emissions by providing the possibility of brake energy recuperation and prime mover operation management. LÄS MER

  5. 4. Optimal bidding of a hydropower producer insequential power markets with riskassessment : Stochastic programming approach

    Författare :Yelena Vardanyan; Mohammad Reza Hesamzadeh; Javier Contreras; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Short-term hydropower planning and bidding under uncertainty is a complicated task. The problem became more challenging with the liberalized market environment within the last two decades. LÄS MER

  7. 5. Optimal Control of Electric Bus Lines

    Författare :Rémi Lacombe; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eco-driving; Electric buses; Bus bunching; Nonlinear programming; Optimal control; Model predictive control;

    Sammanfattning : Bus lines are inherently unstable systems, where any delay tends to be further amplified by the accrued passenger loads encountered at stops downstream. This self-reinforcing mechanism, when combined with the multiple sources of disturbances of an urban environment, can lead to the problem of bus bunching. LÄS MER
