  1. 26. Optimisation of Local and National Energy Systems : Development and Use of the MODEST Model

    Författare :Dag Henning; Carl-Johan Fogelholm; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Energy may be supplied by a multitude of components. Computer simulation helps in finding a beneficial system design. The energy-system optimisation model MODEST has been developed, and it has been applied to municipal, regional, and national energy systems. LÄS MER

  3. 27. Comparative Assessment of Fuel-Based Systems for Space Heating

    Författare :Åsa Karlsson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; cogeneration; district heating; electric heating; external cost; carbon dioxide mitigation; detached houses; fossil fuels; Energy systems; bioenergy;

    Sammanfattning : Replacing fossil fuels by biofuels and increasing energy efficiency are often considered to be options for reducing the net emission of greenhouse gases. This thesis presents the results of analyses of energy efficiency, emission and cost of whole energy system chains, from the natural resource to the end user when heating detached houses in a Swedish context.

  4. 28. Energy Storage Systems in Electrical Distribution Grids : Analysis and implementations of use cases for service stacking

    Författare :Johannes Hjalmarsson; Cecilia Boström; Karin Thomas; Louise Ödlund; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ancillary services; congestion management; distribution grids; energy storage systems; scheduling optimization; service stacking.;

    Sammanfattning : This Ph.D. thesis investigates the possibility of using energy storage systems for multiple services by implementing service stacking, with special emphasis on congestion management in distribution grids. LÄS MER

  5. 29. 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
