  1. 1. Cooperation in local electricity markets : modelling of technical measures

    Författare :Maria Andersson; Björn Karlsson; Curt Björk; Tomas Larsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system; System cost; Electricity market; Co-operation; Demand-side management; Energy efficiency; Shadow prices;

    Sammanfattning : This thesis presents a system analysis for co-operation in local electricity markets including distributors and customers. The purpose of co-operation is to minimise the system cost of local markets by introducing system measures, such as end-use measures and municipal co-generation plants. LÄS MER

  3. 2. Load Shifting and Storage of Cooling Energy through Ice Bank or Ice Slurry Systems : modelling and experimental analysis

    Författare :Marino Grozdek; Per Gunnar Lundqvist; Michael Kauffeld; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigeration systems; cool thermal energy storage system; ice; modelling; simulation; field measurement; experiment; indirect system; ice-on-coil system; external melt; ice slurry; homogeneous storage; heterogeneous storage; Thermal energy engineering; Termisk energiteknik;

    Sammanfattning : Ice based Cool Thermal Energy Storage (CTES) systems have attracted much attention during last few decades. The reasons are mainly of economical and environmental nature. LÄS MER

  4. 3. Cost-effective incentives for local electric utilities and industries in co-operation : modelling of technical measures

    Författare :Maria Andersson; Björn Karlsson; Curt Björk; Tomas Kåberger; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system; System cost; Electricity market; Co-operation; Demand-side management; Energy efficiency;

    Sammanfattning : In the Swedish electricity system there is a great potential for increasing the cost efficiency of the electricity use. However, today the economic incentives, offered for instance by existing electricity rates, are too weak to improve the use of the system. LÄS MER

  5. 4. Efficient Simulation Methods of Large Power Systems with High Penetration of Renewable Energy Resources : Theory and Applications

    Författare :Ebrahim Shayesteh; Lennart Söder; Enrique Acha; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system simplification; power system reduction; power system aggregation; power system equivalencing; renewable energy resources; wind power modelling; storage allocation problem; spinning reserve determination; multi-area power system analyses; power system operation and planning; electricity market analysis.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Electrical energy is one of the most common forms of energy these days. Consequently, electric power system is an indispensable part of any society. LÄS MER

  7. 5. System Expansion and Allocation in Life Cycle Assessment With Implications for Wastepaper Management

    Författare :Tomas Ekvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; paper recycling; waste incineration; environmental life cycle assessment; LCI methodology; allocation; waste management; system expansion; system boundaries; life cycle inventory analysis;

    Sammanfattning : The choice of system boundaries and allocation methods can have decisive effects on the results and conclusions of a life cycle assessment (LCA). System expansion makes it possible to model the indirect effects of a decision; however, this modelling is often based on inaccurate assumptions. LÄS MER
