  2. 16. Technical and Economic Conditions for Efficient Implementation of CO2 Capture - process design and operational strategies for power generation and process industries

    Author : Stefanìa Òsk Gardarsdòttir; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Post-combustion; CCS; chemical absorption; dynamic modeling; industrial sources; CO2 capture and storage; variable electricity generation;

    Abstract : This thesis investigates the operational parameters of fossil-based power generation and industrial processes in future energy systems that have stringent constraints on CO2 emissions, and, consequently, large shares of renewable energy. CO2 capture and storage, which is the focus of this work, is required for power and industrial processes that emit CO2. READ MORE

  4. 17. Balancing variable renewable electricity generation using combined heat and power plants, large-scale heat pumps, and thermal energy storages in Swedish district heating systems

    Author : Svante Monie; Magnus Åberg; Annica Nilsson; Joakim Widén; Magnus Wallén; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating systems; Power-to-Heat; Heat pumps; Combined heat and power; Thermal energy storage; Power balance; Variable renewable electricity; Biomass fuel; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Abstract : The global ambitions to hamper the greenhouse effect has led to ambitious targets for increasing renewable energy use. This, in combination with recent years' vast development of wind and solar power, implies that there will be significant amounts of variable renewable electricity (VRE) in future energy systems.

  5. 18. The roles of transmission and distribution networks in integrating variable renewable electricity generation

    Author : Joel Goop; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electricity generation; demand-side management; energy systems modelling; power systems; variable renewables;

    Abstract : Emission reduction targets, together with other factors, such as security of supply, are driving the expansion of variable renewable energy sources for electricity generation, mainly solar and wind power. Trading across the transmission grid is an important measure to handle the increased variability and to balance supply with demand. READ MORE

  6. 19. Wind-turbine harmonic emissions and propagation through a wind farm

    Author : Kai Yang; Åke Larsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy; Electric power system; Wind power; Power quality; Power system harmonics; Electric Power Engineering; Elkraftteknik; Energy Engineering; Energiteknik;

    Abstract : The increasing demand for sustainable energy is one of the driving forces behind the increasing use of wind power by means of wind-turbines in electric power systems. Modern wind turbines commonly employ variable-speed-generator technology associated with a power-electronic converter as part of the grid connection. READ MORE

  7. 20. Modelling interactions between distributed energy technologies and the centralised electricity supply system

    Author : Joel Goop; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy systems modelling; variable renewables; power systems; distributed generation; demand response; electricity storage;

    Abstract : Renewable electricity generators, such as solar photovoltaics (PVs), and variation management technologies, such as battery storage and demand response (DR) systems, can be deployed in a distributed fashion, which can benefit the overall system. Such distributed energy technologies interact with and influence the centralised generation and transmission systems. READ MORE
