  1. 16. Impact of High levels of Wind Penetration on the Exercise of Market Power in the Multi-Area Systems

    Författare :Ekaterina Moiseeva; Mohammad Reza Hesamzadeh; Frank Anthony Wolak; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind integration; market power; game theory; mathematical programming; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : New European energy policies have set a goal of a high share of renewable energy in electricity markets. In the presence of high levels of renewable generation, and especially wind, there is more uncertainty in the supply. It is natural, that volatility in energy production induces the volatility in energy prices. LÄS MER

  3. 17. Strategies, Methods and Tools for Solving Long-term Transmission Expansion Planning in Large-scale Power Systems

    Författare :Desta Zahlay Fitiwi; Lennart Söder; Michel Rivier; Fernando de Cuadra; Andres Ramos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transmission expansion planning; uncertainty and variability; optimization; stochastic programming; moments technique; clustering; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Driven by a number of factors, the electric power industry is expected to undergo a paradigm shift with a considerably increased level of variable energy sources. A significant integration of such sources requires heavy transmission investments over geographically wide and large-scale networks. LÄS MER

  4. 18. Sustainable Design and Control of Automated Material Handling Systems

    Författare :Maziar Mashaei; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixed integer leaner model.; CPN tool; Universal design framework; Sustainable production philosophy; Conceptual and detailed design phases; Automated material handling system; Pallet system; Synthesis and evaluation methods;

    Sammanfattning : An automated material handling system is a collection of electro mechanical components, electronics, and computer-based devices that act together to maintain flow of parts and materials in a modern production environment. Material flow is a significant factor in the design of manufacturing plants. LÄS MER

  5. 19. Look-ahead Control of Heavy Vehicles

    Författare :Erik Hellström; Lars Nielsen; Jan Åslund; Lino Guzzella; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive control; dynamic programming; predictive control; fuel-optimal control; long haulage truck; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Automatic control; Reglerteknik;

    Sammanfattning : Trucks are responsible for the major part of inland freight and so, they are a backbone of the modern economy but they are also a large consumer of energy. In this context, a dominating vehicle is a truck with heavy load on a long trip. LÄS MER

  7. 20. Optimization models and methods for harvest planning and forest road upgrading

    Författare :Jenny Karlsson; David Martell; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : The purpose of this thesis is to contribute to the development and the use of optimization models and methods to support efficient decision making in Swedish forestry. The main problem areas concerned are forest road upgrade planning and operational harvest planning. Today much of the planning is done manually by experienced managers. LÄS MER
