  1. 26. Modelling Towards Control of Dynamic Systems : Applications on RDF Fired CFB Performance and DHN Distribution

    Författare :Nathan Zimmerman; Konstantinos Kyprianidis; Carl-Fredrik Lindberg; Erik Dahlquist; Natasa Nord; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat and Power; Circulating Fluidized Bed Boiler; District Heating; Model Predictive Control; Feed-Forward; CHP; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The combination of global warming along with increasing energy demand necessitates the importance of improving processes pertaining to the production and consumption of energy in combined heat and power plants. This thesis brings to light transient factors currently burdening process performance for circulating fluidized bed boilers (CFBs) combusting refuse derived fuels (RDFs) and district heating networks (DHN).

  3. 27. On the Selection of Methods and Tools for Analysis of Heat and Power Plants

    Författare :Pernilla Olausson; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Termisk teknik; termodynamik; Thermal engineering; neural networks; LCA; environment; thermoeconomy; exergy; economics; Methods and tools; energy analysis;

    Sammanfattning : The business climate of the energy market has been eventful over the last two decades, particularly with the introduction of the deregulated electricity market and promotion of environmental issues. This has subsequently lead to new analysis criteria, influencing both technology requirements and production costs. LÄS MER

  4. 28. 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

  5. 29. District Heating and CHP : Local Possibilities for Global Climate Change Mitigation

    Författare :Kristina Difs; G. Björn Karlsson; Louise Trygg; Thomas B. Johansson; Linköpings universitet; []
    Nyckelord :District heating; combined heat and power; carbon dioxide emissions; optimisation; energy policies; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Global warming, in combination with increasing energy demand and higher energy prices, makes it necessary to change the energy use. To secure the energy supply and to develop sustainable societies, construction of energy-efficient systems is at the same time most vital. LÄS MER

  7. 30. Exploiting the Synergies from Coupled Electricity and Heat Distribution Networks : Modelling, simulation and optimization based on an extended energy hub approach

    Sammanfattning : Recent literature shows that there is a significant potential of decarbonisation and efficiency improvement that can be achieved through the synergy from multi-energy systems (MESs). Coupling technologies, such as co-generation plants, heat pumps and thermal storages are widely recommended as means of unlocking additional flexibility and increasing the penetration of renewables in the heating and electricity sectors.
