  2. 6. Effects of Irradiation and Thermal Ageing on the Nanoscale Chemistry of Steel Welds

    Author : Kristina Lindgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spinodal decomposition; thermal ageing; low alloy steel; reactor pressure vessel; irradiation damage; atom probe tomography; core barrel; clustering;

    Abstract : Structural materials of nuclear power plants degrade during operation due to thermal ageing and irradiation from the reactor core. Effects on the materials are an increase in hardness and tensile strength, and a decrease in ductility and fracture toughness, i. e. embrittlement. READ MORE

  4. 7. Dynamics of large-scale fluidized bed combustion plants

    Author : Guillermo Martinez Castilla; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operational flexibility; combined heat and power; process control; thermal power plant; biomass combustion;

    Abstract : Fluidized bed combustion (FBC) plants are widely used in energy systems across the world for the thermochemical conversion of solid fuels, and are especially suitable for low-rank fuels (a category to which renewable solid fuels belong). FBC plants are traditionally operated for base-load electricity production and for heat production, both of which processes are characterized by steady and stable operation. READ MORE

  5. 8. A Techno-Economic Framework for the Analysis of Concentrating Solar Power Plants with Storage

    Author : Rafael Guédez; Björn Laumert; Zhor Hassar; Viktoria Martin; Alberto Traverso; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating solar power; thermal energy storage; techno-economic analysis; Termisk solkraft; termisk energilagring; techno-eknomiska analys; Energiteknik; Energy Technology;

    Abstract : Concentrating solar power plants can integrate cost-effective thermal energy storage systems and thereby supply controllable power on demand, an advantage against other renewable technologies. Storage integration allows a solar thermal power plant to increase its load factor and to shift production to periods of peak demand. READ MORE

  6. 9. Combined heat and power plant flexibility - Technical and economic potential and system interaction

    Author : Johanna Beiron; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combined heat and power; Flexibility; Process optimization modeling; Electricity price volatility; Waste to energy; Combined cycle; District heating; Dynamic modeling;

    Abstract : The share of variable renewable energy sources in electricity generation systems is expected to increase, leading to increased variability in the load that must be provided by conventional power plants or other flexibility measures. Thus, thermal power plants need to consider implementation of technical measures that enhance flexibility; to maintain profitability of operation with increased electricity price fluctuation, and to support electricity system stability.

  7. 10. Short Term Scheduling of Hydrothermal Power Systems With Integer Hydro Constraints

    Author : Nilsson Olof; Lennart Söder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro power; Optimization; Integer Constraints; Lagrange relaxation; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The thesis presents models for short term planning (24 hours) of a hyro dominated hydrothermal power system. The purpose of the models is to minimizae the system operation costs to provide a forecasted load and keep enough spinning reserve... READ MORE
