    Sammanfattning : This thesis investigates the role of different short-term electricity market design aspects that can facilitate better coordination of resources within the power system. The work also emphasizes on better cross-border integration of the short-term markets to improve the market liquidity, competition, social welfare, and flexibility in the system, which is essential for facilitating the integration of renewable sources.

  3. 2. On Frequency Control Schemes in Power Systems with Large Amounts of Wind Power

    Författare :Camille Hamon; Lennart Söder; Magnus Perninge; Henrik Hult; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; Stochastic optimal power flows; Frequency control schemes; Tertiary frequency control; uncertainty; power systems;

    Sammanfattning : In recent years, large investments have been made in wind power, and this trend is expected to continue in the coming decades. Integrating more wind power in the production mix offers great opportunities for the society, such as reducing greenhouse gas emissions and the dependence on foreign fuel.

  4. 3. Analytical Results on the Performance of Shared Resource Allocation Systems

    Författare :Iosif Salem; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; energy dispatch problem; shared-object systems; Resource allocation; analytical performance evaluation;

    Sammanfattning : Resource allocation is a prevalent problem in a wide range of domains of computer science. Analytical tools that evaluate the performance of resource allocation systems allow us to compare with experimental ones, and utilize the design of such systems. LÄS MER

  5. 4. Optimisation and Incentive Mechanisms for Robust Generation Dispatch and Capacity Investment in Electricity Markets

    Författare :Lamia Varawala; György Dán; Mohammad Reza Hesamzadeh; José Manuel Arroyo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal power flow; Look-ahead; $N-k$ contingency criterion; Renewable energy; Environmental externalities; Electricity generation capacity; Strategic behaviour; Incentives;

    Sammanfattning : Power systems constitute a large-scale critical infrastructure and therefore, it is crucial that their operation be robust to deviations from normal functioning of its independent components. Furthermore, due to their large size, any inefficiencies in electricity market design can be very costly and therefore, must be optimised. LÄS MER

  7. 5. Energy system operation by Lagrangian relaxation

    Författare :Erik Dotzauer; Andrew B. Philpott; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Due to its relatively high total energy efficiency, the application of cogeneration, i.e. simultaneous exploitation of power and heat from the energy transformation process, is receiving increased attention. In many countries cogeneration is today an essential element in the energy supply system. LÄS MER
